[001] [001] This application claims priority for US Provisional Patent Applications serial numbers 62 / 532,710 filed on July 14, 2017, 62 / 549,655 filed on August 24, 2017, and 62 / 588,276 filed on November 17, 2018 , whose descriptions are incorporated by reference here. Field of the Invention
[002] [002] The present description refers in general to ultra-low form factor optical connectors and related connections in optical adapters and transceivers. Foundations
[003] [003] The prevalence of the Internet has led to unprecedented growth in communication networks. Consumer demand for service and increased competition has led network providers to continually seek ways to improve service quality, while reducing cost.
[004] [004] Certain solutions included the provision of high density interconnected panels. High-density interconnected panels can be designed to consolidate the increasing volume of interconnections needed to support fast-growing networks in a compact form factor, thereby increasing service quality and decreasing costs, such as floor space and support air. However, there is still room for improvement in the area of data centers, specifically with regard to fiber optic connections. For example, manufacturers of connectors and adapters are always looking to reduce the
[005] [005] In communication networks, such as data centers and switching networks, numerous interconnections between conjugated connectors can be compacted into high density panels. Panel and connector producers can optimize such high densities by decreasing the size of the connector and / or the spacing between adjacent connectors on the panel. While both approaches can be effective in increasing the density of panel connectors, decreasing connector size and / or spacing can also increase support costs and decrease quality of service.
[006] [006] In a high density panel configuration, adjacent high density cable and connector sets can obstruct access to individual release mechanisms. Such physical obstructions can prevent an operator's ability to minimize the stresses applied to cables and connectors. For example, these stresses can be applied when the user reaches a dense group of connectors and separates the surrounding optical fibers and connectors to access an individual connector release mechanism.
[007] [007] Although an operator may attempt to use a tool, such as a screwdriver, to reach a dense group of connectors and activate a release mechanism, adjacent cables and connectors can obstruct the operator's line of sight, making it difficult to guide the tool for the release mechanism without separating the adjacent cables. In addition, even when the operator has a clear line of sight, guiding the tool to the release mechanism can be a time-consuming process. Thus, the use of a tool may not be effective in reducing support time and increasing quality of service. SUMMARY OF THE INVENTION
[008] [008] An optical connector that holds two or more optical ferrules type LC is provided. The optical connector includes an outer body, an inner front body that accommodates two or more LC-type optical ferrules, ferrule springs to propel the optical ferrules towards a conjugate receptacle, and a support body to support the ferrule springs. The outer body and the inner front body are configured in such a way that four LC-type optical ferrules are accommodated in a small form-factor pluggable transceiver footprint (SFP) or eight LC-type optical ferrules are accommodated in a plug-in type transceiver footprint. small quad form factor (QSFP). A conjugate receptacle (transceiver or adapter) includes a receptacle hook and a housing with an opening that accommodates the receptacle hook in a flexed position as the optical connector connects to the conjugate receptacle by inserting the receptacle hook into a recess of optical receptacle hook. BRIEF DESCRIPTION OF THE DRAWINGS
[009] [009] This description is not limited to the particular systems, devices and methods described, as these may vary. The terminology used in the description is only for the purpose of describing the particular versions or modalities, and is not intended to limit the scope.
[0010] [0010] In the form used in this document, the singular forms "one", "one", and "o", "a" include plural references, unless the context clearly dictates otherwise. Unless otherwise defined, all technical and scientific terms used here have the same meanings as are normally understood by one skilled in the art. Nothing in this description should be construed as an admission that the modalities described in this description are not authorized to predate such description by virtue of a previous invention. As used herein, the term “comprising” means “including, but not limited to”.
[0011] [0011] The following terms must have, for the purposes of this request, the respective meanings presented below.
[0012] [0012] A connector, in the form used here, refers to a device and / or components of it that connects a first module or cable to a second module or cable. The connector can be configured for fiber optic transmission or electrical signal transmission. The connector can be any suitable type currently known or later developed, such as, for example, a ferrule connector (FC), a fiber distributed data interface connector (FDDI), an LC connector, a mechanical transfer connector ( MT), a square connector connector (SC), a CS connector, or a straight tip connector (ST). The connector can generally be defined by a connector housing body. In some embodiments, the housing body may incorporate any or all of the components described here.
[0013] [0013] A “fiber optic cable” or an “optical cable” refers to a cable containing one or more optical fibers to conduct optical signals in
[0014] [0014] Several modalities described here in general provide a remote release mechanism in such a way that a user can remove connectors from the cable assembly that are spaced on a high density panel without damaging the surrounding connectors, accidentally disconnecting the surrounding connectors, interrupting transmissions through surrounding connectors, and / or the like. A number of modalities also provide narrow-pitch LC duplex connectors and small-width multi-fiber connectors, for use, for example, with future narrow-narrow LC and future narrow-width SFPs. The remote release mechanisms allow the use of narrow duplex LC duplex connectors and small width multi-fiber connectors in dense arrays of narrow narrow LC LC and small width multi-fiber SFPs.
[0015] [0015] FIG. 1A shows a perspective view of a standard 6.25mm pitch LC connector of the prior art 100. The SFP 100 is configured to receive a duplex connector and provides two receptacles 102, each to receive a respective LC connector. Step 104 is defined as the geometric axis to geometric axis distance between the central longitudinal geometric axes of each of the two receptacles 102. FIG. 1B shows a perspective view of a prior art standard 6.25 mm LC adapter 106. Adapter 106 is also configured to receive a duplex connector, and provides two receptacles 108, each to receive a respective LC connector. FIG. 1C is a top view of the adapter 106 of FIG. 1B. The pitch of adapter 106 is defined similarly to that of SFP 100, as the axis-to-axis distance between
[0016] [0016] FIG. 2A shows a prior art LC duplex connector 200 that can be used with conventional SFP 100 and conventional adapter 106. The LC duplex connector 200 includes two conventional LC connectors 202. FIG. 2B shows another prior art LC duplex connector 204 having a remote release pull tab 206, and including two conventional LC pull connectors 208. As shown, the remote release pull tab includes two teeth 210, each configured to attach to the extension member 212 of a respective LC connector 208. FIGS. 2C and 2D show top and side views, respectively, of the conventional LC connector 208, having a width of 5.6mm, and additionally showing the extension member 212.
[0017] [0017] As discussed here, current connectors can be improved by various means, such as, for example, reducing the footprint, increasing the structural resistance, allowing changes in polarity, etc. Several modalities described here offer improvements over the current state of the art technology, as will be further discussed below.
[0018] [0018] In some embodiments, as shown in FIG. 3, a connector 300 may comprise several components. Referring to FIG. 3, an illustrative embodiment of a connector 300 is shown in an exploded view to show detail. In some embodiments, and as further discussed here, a connector 300 may have an outer housing 301, a front body 302, one or more ferrules 303, one or more ferrule flanges 304, one or more springs 305, a support body 306 , a rear post 307, a crimp ring 308, and a boot 309. In some embodiments, the support body 306 may comprise one or more protrusions 306.1 that can lock with a window / cutout 302.1 on the front body 302. This can
[0019] [0019] Referring now to FIG. 4, an embodiment is shown in which the connector 400 is mounted. In some embodiments, the mounted connector may have an outer housing 401, a front body 402 positioned within the outer housing, one or more ferrules 403, one or more ferrule flanges (not shown), one or more springs (not shown), a support body 406, a rear post (not shown), a crimp ring (not shown), a boot 409, and a push-pull tongue 410. In some embodiments, the connector may have one or more locking mechanisms consisting of a window 412 in the outer housing 401 next to the push-pull tongue 410 and a protrusion 413 in the front body. The locking mechanism constituted by the window 412 and the protrusion 413 securely fix the outer housing 401 to the front body 402. In an additional embodiment, the outer housing 401 can have a recess 411 to receive a locking tongue or locking mechanism from an adapter (shown in FIG. 13, below). The recess 411 of the outer housing 401 is used to lock with an adapter (shown in FIG. 13, below) or transceiver receptacle to secure the connector to the adapter. As those skilled in the art should understand, the push-pull tab 410 allows removal of the connector from a receptacle without requiring additional tools. Alternatively, the push-pull tab can be removed and the connector removed manually. In one or more modalities
[0020] [0020] FIG. 5 represents a procedure for changing the polarity of the optical connectors of the present description. As shown in FIG. 5, in some embodiments, the locking mechanism of the connector 500 may consist of two main parts: a window (not visible) and one or more protrusions 513. As illustrated in FIG. 5, the outer housing 501 can slide into or be removed from the front body 502 by disengaging the locking mechanisms formed by the protrusion 513 that exit through the window, by which it makes contact with a rear window wall (refer to FIG 4 for an illustrated example of the outer housing being attached to the front body via the locking mechanism). In some embodiments, the push-pull tab 510 can be permanently attached to the outer housing 501, as shown.
[0021] [0021] The front body 502 can be removed from the external housing 501, rotated 180 ° as indicated by the arrow 520, and reinserted in the external housing. This allows for a change in the polarity of the front body 502, as shown by the arrow diagram in FIG. 5, and therefore ferrules can switch quickly and easily without unnecessarily jeopardizing delicate fiber cables and ferrules.
[0022] [0022] In some embodiments, it may be beneficial to connect two or more connectors together to increase structural integrity, reduce the overall footprint, and cut manufacturing costs. Accordingly, as shown in FIG. 6, a connector 600 may, in some embodiments, use an external housing 601 which is capable of containing two front bodies 602. Several other embodiments are described here, and it should be noted that the embodiments described here are all non-limiting examples shown for explanatory purposes only.
[0023] [0023] Thus, although the modality shown in FIG. 6 use a 601 duplex external housing, additional or alternative modes may exist with more capacity, for example, six or eight optical connectors within a single external housing. As shown in FIG. 6, in some embodiments, the outer housing 601 can accept two front bodies 602, each with two separate ferrules 603. As shown, the front body (s) 602 can (m) attach firmly to the outer housing 601 by means of the locking mechanism 612 and 613. In additional embodiments, the push-pull tongue 610 can be modified, as shown, in such a way that a single tongue can be used to release the two or more connectors of an adapter. As illustrated in FIG. 6, the push-pull tab 610 and the outer housing 601 of a single body can have two windows 612 with which they receive multiple protrusions 613 of the front body (s) 602. As discussed here, the recesses 611 of the outer housing 601 are used to attach the connectors to an adapter (shown in FIG. 13 below). In one or more additional embodiments, the connectors may have individual support bodies 606 and boots 609 (i.e., one support body / boot per front body) as shown.
[0024] [0024] Alternatively, in some embodiments, such as that shown in FIG. 7, connector 700 may have a single boot 709 and a duplex support body (i.e., single body) 706 instead of individual support bodies (for example, as shown in FIG. 6). In some embodiments, the duplex support body 706 may have different dimensions than the individual support bodies of FIG. 6, such as, for example, they can be longer to accommodate the need for routing the fiber after it leaves the boot 709. As with other modalities discussed here, the connector shown in FIG. 7 may also include an outer housing (e.g. duplex outer housing) 701, one or more ferrules 703, at least one locking mechanism formed by the protrusion (not shown)
[0025] [0025] As stated, it can be beneficial to connect two or more connectors to each other to increase structural integrity, reduce the overall footprint, and cut manufacturing costs. Thus, similar to FIG. 6, FIG. 8 shows a connector 800 which can, in some embodiments, use an external housing 801 which is capable of containing multiple (e.g., four) front bodies 802.
[0026] [0026] As shown in FIG. 8, some embodiments may have an outer housing 801 capable of accepting up to four frontal bodies 802, each with one or more ferrules 803. As shown, each frontal body 802 can securely attach to the outer housing 801 by means of the locking mechanism 812 and 813. In additional embodiments, the push-pull tongue 810 can be modified in such a way that a single tongue can be used to remove up to four connectors from an adapter. As illustrated in FIG. 8, the push-pull tab 810 can include four recesses 811, which, as discussed here, are used to secure the connector to a receptacle such as an adapter (shown in FIG. 13, below) or the front receptacle portion of a transceiver. In one or more additional embodiments, the connectors may have individual support bodies 806 and individual boots 809 (i.e., a support body / boot per front body) as shown.
[0027] [0027] Similar to FIG. 8, FIG. 9 shows an embodiment where the outer housing 901 is capable of accepting up to four front bodies 902, each with one or more ferrules 903. As shown, each front body 902 can securely attach to the outer housing 901 by means of the locking mechanism 912 and 913. In additional embodiments, the push-pull tab 910 can be modified in such a way that a single tab can be used to remove up to four CS connectors from an adapter. Like
[0028] [0028] In another aspect, the present description provides a method for reconfiguring optical cables in which the outer housings of the connectors can be removed and the remaining portion of the mounted connector is inserted into a housing having a greater or lesser capacity. For example, the outer housings of several ferrules of two ferrule capacity can be removed and the inner body of the connector and associated components inserted in a second outer housing which has both a four ferrule and an eight ferrule capacity. Alternatively, an external housing with a capacity of four ferrules can be removed and the internal bodies and associated components are inserted into two second external housings, each of the two second housings having a capacity of two ferrules. Similarly, an external housing with a capacity of eight ferrules can be removed and replaced with two housing of four ferrule capacity or two housing of two ferrule capacity. In this way, the cables can be flexibly reconfigured to match the capacity of a corresponding optical-electrical component such as a transceiver. This aspect of the present description is demonstrated with reference to FIG. 10.
[0029] [0029] Referring now to FIG. 10, several modalities can exist such as a single housing 1001 that receives a single connector
[0030] [0030] Alternatively, in some embodiments, the connector can use one or more duplex support bodies with a single boot, similar to that shown in FIG. 7. Thus, similar to FIG. 7, a modality can allow for an even smaller footprint, less cabling, and easier maintenance of the connector. In this way, one or more modalities can have an external housing that can accept up to four frontal bodies, each with one or more ferrules. In some embodiments, each front body can be securely attached to the external housing by means of a locking mechanism. In additional embodiments, the push-pull tongue can be modified in such a way that a single tongue can be used to release up to four front bodies of an adapter. The push-pull tab can include four openings with which it receives multiple locking tabs from the outer housing. As discussed here, the locking tabs on the outer housing are used to attach the connectors to an adapter (shown in FIG. 13) or to the optical receptacle portion of a transceiver.
[0031] [0031] In additional modalities, the connector can use a single monoblock support body with a single boot (that is, as shown in FIG. 9). Thus, a modality can allow for an even smaller footprint, less cabling, and easier maintenance of the connector. In this way, one or more modalities can have an external housing that can
[0032] [0032] The optical connectors of this description are all configured to be received in a receptacle. In the form used here, the term "receptacle" refers generally to a housing that receives an optical connector. A receptacle includes both optical adapters, that is, components that correspond to two or more optical connectors, and transceivers, which include an optical receptacle that contains connectors that are for communicating with an optoelectronic component (for example, a component that converts optical signals into signals electrical). As shown in FIG. 11A, in an 1100A embodiment, the outer housing 1101 may comprise one or more recesses 1111. As discussed and shown here, one or more recesses may allow a receptacle 1114 to securely connect to connector 1100A. Thus, in some embodiments, receptacle 1114 may have a receptacle hook 1115, which is flexible and can attach connector 1100A to the receptacle by means of locking on the recess wall 1111, as shown. This locking occurs when the outer housing 1101 is pushed forward into the receptacle. The inclined portions of the outer housing 1101 allow the receptacle hook 1115 to slide up and over the front of the outer housing thereby securing the connector 1100A within the receptacle.
[0033] [0033] Additionally, or alternatively, in some
[0034] [0034] Referring now to FIGS. 12A and 12B, as discussed here and previously shown in FIG. 5, the front body 1202 can be removed from the outer housing 1201. In some embodiments, a portion of the outer body 1201 can be flexibly extended out of the front body 1202 as shown by the arrows in FIG. 12A. as discussed here, in some embodiments, the front body 1202 may comprise a protrusion 1213 that locks with a window (not shown) in the outer housing 1201. Thus, when force is applied to the outer housing 1201 in a way that removes one or more protrusions 1213 of one or more windows (not shown, see FIG. 4), the front body 1202 can be removed from the outer housing.
[0035] [0035] Referring now to FIG. 13, a modality 1300 is shown in which the connector (not shown in its entirety) is inserted into a receptacle such as adapter 1314. In this specific non-limiting example, the connector is similar to that shown in FIG. 8 (that is, comprising four front bodies each with its own support body 1306 and boot 1309). However, unlike FIG. 8, the mode shown here uses four individual 1310 push-pull tabs instead of a duplex push-pull tab system that handles two
[0036] [0036] Various benefits and details have been discussed here with respect to the connectors and their modular capacity (for example, to include multiple connectors in a single housing). In addition to the reduced footprint, structural improvements and cost reduction, several modalities here can also be beneficial in terms of reducing the cabling load in a data center environment. Illustrative modalities shown in FIGS. 14A through 14C represent cable configurations that can be used to reduce the complexity of optical cables in a compact environment. Note that any of the optical connectors described in this description can be used in these modalities, including the optical connectors of FIGS. 21B, 37 and 41, to be discussed in detail below. FIG. 14A shows two duplex cables similar to the cable shown in FIG. 6. In some embodiments, one or more detachable clamps 1401 can be attached to two or more zip cables to prevent the zip cables from becoming detached. This allows two or more cables to be bundled and reduces the risk of entanglement with additional cables. FIG. 14B is an illustrative example of how easy it is for a modality to be able to separate into two individual connectors disuniting the cables and thus quickly and easily creating two independent fiber optic channels that can move and be connected independently. FIG. 14C shows an embodiment in which a duplex connector like that of FIGS. 6 and 14A is connected to two separate individual connectors. By the variable housing configurations shown above in FIG. 10, the cable of FIG. 14A can be reconfigured like the cables of both 14B and FIG. 14C.
[0037] [0037] In addition to connecting existing fiber cables, some modalities here can use a new four-fiber zip cable. Referring now to FIG. 15A, a conventional zip cable (that is, one with a single filament of
[0038] [0038] A specific example using multiple filament cables is shown in FIG. 16 for illustrative purposes only. It should be understood that numerous alternatives and modifications are possible, such as, for example, that shown in FIGS. 18A-18B and FIGS. 19A-19D. As shown, a 1630 switch (for example, 100G switch) is shown with a 1631 transceiver (for example, 100G transceiver). The 1631 transceiver has a receptacle for receiving 1632 duplex connectors. From each of the two 1632 duplex connectors, a cable 1633 four-fiber extends to connect to several other connectors and transceivers. In some embodiments, as discussed here, a 1640 clamp (for example, detachable clamp) can connect two or more cables (for example, 1633) to ensure that the zip cables do not come apart. As shown, a 1633 four-fiber cable is divided into two 1634 two-fiber cables, which are then attached to a single 1635 simplex connector and placed on a 1636 transceiver (eg 25G transceiver). As additionally shown, a of the 1637 four-fiber cables is connected to a single 1638 duplex connector, which is then inserted into another transceiver (for example, 50G transceiver)
[0039] [0039] An additional or alternative embodiment is shown in FIG.
[0040] [0040] Thus, the modalities described here allow for improvements in relation to the current cutting edge technology. As a specific example, connectors in general have three types of fixed cables. In addition, some cables can be split. As such, the cable cannot be split once installed and the polarity of the cables cannot be changed. Alternatively, the modalities discussed here may allow a user to switch from a four-way connector to a 2-Duplex, to a 4-simplex, etc. (for example, FIG. 20). In addition, as discussed here, individual connectors can be divided into individual connectors at any time, even after arrangement. In addition, the polarity can be within the connectors easily in a way that poses no risk of damage to one or more ferrules and fibers, as discussed herein. It should also be noted that the connectors depicted are used here for illustrative purposes only, and that several other connectors can be used in any mode (for example, an MT connector, such as that shown in FIGS. 18A-18B, and the connectors figures of Figures 21, 37 and 41).
[0041] [0041] FIGS. 18A-18B depict an optical connector including a MT 1810 ferrule in a housing that is substantially similar to the housing 301 of FIG. 3. As with the embodiment of FIG. 3, the various features of the connector are configured in such a way that two connectors
[0042] [0042] FIGS. 19A-19D show alternative modalities of the optical connectors of FIG. 3 in which the push-pull tabs are not integrated with the optical connector housing. As seen in FIGS. 19A-19B, a push-pull tongue 1930 is a separable element from a connector housing. The push-pull tongue 1930 acts as a latch 1910 to insert and extract the connector of an adapter or transceiver. An alternative latch mechanism is shown in FIGS. 19C-19D. The 1950 latch includes a groove that is actuated by the 1960 push-pull tongue.
[0043] [0043] FIG. 20 represents the disassembly of a four connector housing (two duplex connectors in a single housing) into two duplex connectors. This can be done when changing, for example, a connector as shown in FIG. 14A for a connector as shown in FIG. 14C. In FIG. 20, an optical connector 2000 is shown including a housing 2010 that houses two duplex connectors (four optical fibers). The 2010 housing is removed, leaving the two duplex connectors 2020. Two 2030 housings are then provided and two individual 2040 duplex connectors are then created from the single initial housing connector 2000. This reconfigurable housing simplifies cable management, for example, when optical cables are interconnected between lower speed transceivers and higher speed transceivers as seen in FIG. 16.
[0044] [0044] FIG. 21A represents an embodiment of an optical connector 2100, shown in the exploded view, while 21B represents the optical connector 2100 in an assembled view. The optical connector 2100 may include an outer housing 2110, a front body 2115, one or more ferrules 2122,
[0045] [0045] In optical connectors of the prior art, an internal closed housing was used in place of the open front body 2115. The front body 2115 includes top and bottom portions, but no side walls, called "open side walls" in this modality. By using the front body 2115, the space occupied by the side walls of the internal housing of the prior art is available to increase the density of optical connectors in a given footprint, an advantage over the connectors of the prior art. It was determined that the outer housing 2110, combined with the front body 2115, provided sufficient mechanical strength and ferrule protection, advantageously providing the space for additional optical connectors. Removing the side walls increases the available space by 1-2 mm.
[0046] [0046] Note that, in this modality, the external housing is configured to contain two optical ferrules 2122. Typically, two optical ferrules can be used in a pairing for “transmission” and “reception” of optical fibers, called a duplex connector. However, the outer housing can be configured to contain more or less optical ferrules, including a single optical ferrule, multiple of single optical ferrules, or multiple pairs of optical ferrules, depending on the application. Additionally, the front body 2115 can be removed from the housing
[0047] [0047] Back to FIGS. 29A and 29B, isometric and front views of the outer housing 2110 are shown. As seen in the front view of FIG. 29B and in the cross sectional view of FIG. 29C, 2910 connector orientation protrusions are provided inside the outer housing
[0048] [0048] FIGS. 35A-35C represent the sequence of operations to remove a front mounted body from the outer housing in order to reverse the
[0049] [0049] In some embodiments, the support body 2130 may comprise one or more protrusions or hooks 2134, but well seen in FIGS. 28A and 28B, which can lock with a window / hook cutout of the support body 2119 on the front body 2115. This can allow the support body 2130 and the front body 2115 to be securely attached to each other around the ferrule (s) 2122, ferrule flange (s) 2124, and spring (s) 2125. The support body 2130 includes a cable hole 2820, spring guides 2132, and side protrusions 2810.
[0050] [0050] During assembly, ferrule flanges 2124 fit ferrule flange alignment slots 2117 (see FIGS. 27A and 27B) adjacent to ferrule openings 2116 in front body 2115, compressing springs 2125 (preload) that are positioned along spring supports of the front body 2118. The ends of the springs 2125 are secured in spring guides 2132 (FIGS. 28A, 28B) of the support body 2130 by the spring tension. As seen in the assembled cross sectional views of FIGS. 23A and 23B, springs 2125 are positioned to urge ferrules 2122 to contact conjugated connectors or transceiver optics, ensuring minimum
[0051] [0051] Additional reductions in the size of the connector can be obtained by reducing the size of the springs 2125, see FIG. 21. Using a maximum spring external diameter of 2.5 mm, the pitch of the ferrules, that is, the spacing between adjacent ferrules, can be reduced to 2.6 mm when coupled with the removal of the internal housing walls and walls that separate adjacent ferrules. This advantage is best seen in FIG. 22 representing the front of the connector 2100 showing the general dimensions of the connector and ferrule pitch. Connector size 4.2 x 8.96 x 30.85mm (excluding optional pull tab 2107 and connector alignment key 2105) with a 2.6 mm ferrule pitch.
[0052] [0052] As best seen in FIG. 21B, the outer housing 2110 and the front body 2115 together provide a receptacle hook ramp 2940 (in the outer housing) used to guide a receptacle hook to a receptacle hook recess 2170 (in the front body 2115), also shown in FIGS. 27A and 27B (receptacle hook recess 2710 and receptacle hook retainer surface 2720). The receptacle hook, to be discussed in more detail below, can be an adapter or a transceiver to fix the optical connector 2100 to it.
[0053] [0053] The 2100 optical connectors can be used in a variety of connection environments. In some applications, the 2100 optical connectors will match other optical connectors. Typically, this correspondence will occur with a receptacle such as an optical transceiver adapter or receptacle. An exemplary adapter 2400 shown in FIG. 24 in an exploded view and shown in FIG. 31 having four
[0054] [0054] Back to FIG. 24, additional size reductions in the overall optical connector set plus adapter or connector plus transceiver can be achieved through several connection mechanisms to be described with respect to the 2400 adapter, but they also apply to optical connection features at the front end of the transceiver 3600. Adapter 2400 includes an adapter housing 2402 having an adapter alignment assembly 2430 positioned therein. The adapter alignment set 2430 includes alignment liners 2410 positioned within alignment liner openings 2440 of alignment liner holders 2442. The adapter alignment set additionally includes receptacle hooks 2302 that will take the connectors
[0055] [0055] It should be understood that the presented description of connection mechanisms with respect to the 2400 adapter can be applied in a substantially similar manner with respect to the 3600 transceiver receptacle. In particular, the 3600 transceiver receptacle may include a receptacle housing having a receptacle alignment set positioned thereon. The receptacle alignment assembly includes alignment liners positioned within the alignment liner openings of the liner liner supports. The receptacle alignment assembly further includes receptacle hooks that will pick up optical connectors 2100 through the connector hook recess of the front body 2710 of FIG. 21B. As seen in FIG. 30, receptacle hooks 2302 include an inner surface 3110. The receptacle housing additionally includes connector alignment slots that correspond with the connector alignment key of FIG. 21A. The 2100 connectors are received through the connector opening of the receptacle housing which also includes a bending tab, cutout, mounting plate and panel hook. To assemble the
[0056] [0056] To further reduce the size of optical connectors and associated conjugate components, adapter housing 2402 includes receptacle hook openings 2420, seen in FIGS. 25A and 25B. Receptacle hook openings 2420 accommodate the clearance required by receptacle hooks 2302 when they flex upward before locking with connectors 2100. Interaction of receptacle hooks 2302, having angled internal surfaces 3110 with receptacle hook openings 2420 it is best seen in FIGS. 32B and 34A-C. Before locking (FIG. 34A), receptacle hook 2302 is in an uninflected condition inside the receptacle (adapter or transceiver). As connector 2100 is inserted into adapter housing 2402 or the transceiver, receptacle ramp 2490 presses against internal surfaces of receptacle hook 3110, flexing receptacle hook 2302 in receptacle hook opening 2420. Without provision from the opening, additional clearance would need to be provided to accommodate the flexion of receptacle hook 2302. This additional required clearance is shown on the prior art connector / adapter of FIG. 32A. As seen in FIG. 32A, a 3210 connector lock gap must be provided in the prior art to accommodate prior art connector hooks, increasing the overall footprint of the prior art connector / adapter assembly. By providing receptacle hook openings 2420 in the present description, approximately 2.25mm of the actual valuable footprint state is obtained, which can be used to increase connector density.
[0057] [0057] Another improvement in adapter size is achieved by removing the prior art adapter walls between adjacent connectors. This is best seen in the front view of a mounted adapter
[0058] [0058] FIG. 31 represents a 2400 mounted adapter with four pairs of conjugated connectors 2100 locked in them. Note that, in the locked position, receptacle hooks 2302 do not extend into receptacle hook openings 2420. This is additionally visible in the cross-sectional view of a mounted adapter 2400 of FIG. 25A. Connector alignment keys 2105 are positioned within connector alignment slots 2403. As seen in the cross-sectional view of FIG. 23A, the push-pull tongue 2017 can extend beyond the connector boot 2145 providing clearance to easily grab the tongue and remove a connector. Also seen in FIG. 31 is the adapter flexing tongue 2401 and panel hook 2490 for interaction with shelves or other equipment.
[0059] [0059] In the various features described above, the density of 2100 optical connectors that can be provided in the standard transceiver footprint connector footprint spaces can be doubled. For example, in a 14 x 12.25 mm plug-in small form factor (SFP) footprint, two 2100 connectors having four 1.25 mm outside diameter 2122 type LC ferrules can be accommodated as seen in FIG. 33B. Similarly, in a 13.5 x 19mm quad form factor (QSFP) pluggable footprint, four 2100 connectors having a total of eight LC 2122 ferrules can be accommodated as seen in FIG. 33A. Additionally, providing the connectors in transmission and reception pairs, greater flexibility in
[0060] [0060] Back to FIG. 37, another embodiment of an optical connector is shown. In this embodiment, the last two digits of each element correspond to similar elements in the optical connector of FIG. 21A et seq. In FIG. 37, connector 3700 may include an outer housing 3710, a front body 3715, one or more ferrules 3722, one or more ferrule flanges 3724, one or more springs 3725, a support body 3730, a rear post 3735, a ring crimping tool (represented with an optional thermal contraction tube extending from it), and a boot
[0061] [0061] In FIG. 38, an isometric view of the front body 3715 is shown. In this embodiment, the 3819 support body hook cut moved forward, advantageously reinforcing the connector mounted in side loading environments. A 3895 alignment tongue is provided to correspond with a receiving recess in the support body. The receptacle hook recess 3910 operates in a substantially similar manner to the recess of FIG. 21A, described above. A 3817 ferrule flange alignment slot is also provided.
[0062] [0062] In FIG. 39, the support body 3730 is shown, showing the recess of the alignment tongue 3997 to receive the alignment tongue 3895. The front body hook 3934, for interconnection in the hook cutout of the support body 3819, extends out of the portion
[0063] [0063] As seen in FIGS. 40A-40C, the mounted front body 3715 can be removed from the outer housing 3710, rotated 180 ° as indicated by the arrow (FIG. 40B), and reinserted into the outer housing (FIG. 40C). This allows a change in the polarity of the 3715 front body, so ferrules can switch quickly and easily without unnecessarily jeopardizing delicate fiber cables and ferrules. As previously described with reference to FIGS. 35A-35C, connector flap 3703 is flexed out to release the front body from the outer housing.
[0064] [0064] Back to FIG. 41, another embodiment of an optical connector is shown. In this embodiment, the last two digits of each element correspond to similar elements in the optical microconnectors of FIG. 21A and FIG. 37. In FIG. 41, connector 4100 may include an outer housing 4110, a front body 4115, one or more ferrules 4122, one or more springs 4125, a support body 4130, a crimp ring 4140, and a boot 4145. The outer housing 4110 may include a connector flap 4103 and an optional pull tab 4107 to facilitate removal of the 4100 connector when connected to a dense array of optical connectors. Optionally, ferrules can be ferrules type LC having an outside diameter of 1.25 mm.
[0065] [0065] As seen in FIG. 42A, the front body 4015 in this embodiment includes an intermediate wall 4260 disposed between the ferrules and the springs when the front body is mounted. This intermediate wall reduces the possibility that the springs are intertwined with each other, connecting the connector and breaking the optical fibers. Front body 4015 also includes an alignment cutout guide 4625, seen in the side view of FIG. 42B.
[0066] [0066] The support body 4030, shown in an enlarged view in FIG. 43, includes an alignment guide 4377 that fits the alignment cutout guide 4265 of FIG. 42B. The 4378 wall frame also holds the front body to prevent overcompression of the springs and provides resistance under a lateral load.
[0067] [0067] Several modifications in the external housing, represented in FIGS. 44A-44C, can be used with any of the optical connectors shown in FIGS. 21, 37 and 41 or previous modalities. In FIG. 44A, the push-pull tongue 3707 can include a 4473 release recess. The 4473 release recess allows insertion of a tool or nail to remove the connector from an adapter or transceiver without disturbing adjacent connectors. Similarly, FIG 44B represents a release hole 4499 in the push-pull tongue 3707 to allow insertion of an extraction tool to remove the connector from an adapter or transceiver. FIG. 44C shows a modified connector flap 3703 with a larger cutout size of 1 mm to facilitate the insertion of a tool or a finger to flex the flap 3703 and remove the front body assembly while performing a polarity change or body aggregation with other frontal bodies in a larger external housing.
[0068] [0068] Another embodiment of a transceiver adapter / receptacle is shown in FIG. 45. Unlabeled elements are substantially similar to the elements represented in FIG. 24. In this FIG., The adapter housing hooks 4532 can be seen together with receptacle hooks 4502. Back to the cross-sectional view of the adapter mounted in FIG. 46, the engagement of these elements can be seen.
[0069] [0069] Another embodiment of an optical connector 4700 is shown in FIG. 47. The optical connector of FIG. 47 includes external housing 4710, front body 4715, ferrules 4722, springs 4725, support body 4730, rear post 4735, crimp ring 4740, and boot 4745. Here, the emphasis is on the support body, 4730. A more detailed view of the support body 4730 is shown in FIG. 48. In this embodiment, the rear post flange has a substantially rectangular shape in order to narrow the overall connector profile by approximately 0.5 mm. Overmolding the rear post 4859 accommodates the rear post flange 4857 and reduces the potential for rear post breakage. The rear wall 4853 is extended in length from 1.5 mm to 3 mm to improve the lateral load resistance of the general connector. The positioning of the 4855 crimp ring is reversed from previous modalities to improve the aramid fiber retention of a fiber optic cable, improving the retention of the cable on the rear post.
[0070] [0070] Many advantages are achieved by the rear pole of FIG.
[0071] [0071] In view of the various modifications of this modality, FIG. 50 represents a front view of the 4700 connector showing the reduced overall 3.85 mm connector width. Such a reduction in size allows 4 optical connectors (a total of 8 ferrules) to be accommodated in a 16mm transceiver or connector footprint (including tolerances). In this way, the connectors of the present invention can be used to connect 8 fibers housed in LC ferrule in a QSFP footprint.
[0072] [0072] To further decrease the space required by the optical connectors, a reduction in the lateral thickness can be performed in the connector boot 4700. The reduction in the lateral thickness 5103, represented in FIG. 51, narrows the boot thickness anywhere, reducing the space required by the boot to a 3.85 mm profile of 4700 connector. In this way, four connectors will fit into the QSFP transceiver footprint. This footprint is shown in the front view of the adapter of FIG. 52- as noted here, the front view of an adapter and that of a transceiver are substantially similar from an optical perspective. In FIG. 52, the internal wall of the adapter is reduced from 17.4 mm to 16 mm. All modifications shown in the embodiment of FIG. 47 et seq. They allow the four connectors to fit the profile of FIG. 52.
