    Due to the exponential increase in the amount of information needed by subscribers at the same time as the industry is developing, began an era of fiber in the home (FTTH), in which optical cables reach inside buildings to increase the amount of information transmitted in a remarkable way.
    In some telecommunication networks, a hybrid cable, which transmits both optical signals and power signals, is connected to equipment or other devices, such as a heat exchanger, a base station (FIG. BS) or a remote radio head (RRH), to finally enable the transmission and reception of a high-frequency wireless signal or the like. In addition, the rapid increase in mobile communication data traffic, attributed to the introduction and proliferation of smartphones, has resulted in the faster-than-expected introduction of 4th Generation (4G) communication. (the 5th generation to be followed shortly), and communication service providers have improved structures for efficient network deployment and reduced cost of operation.
    As the number of antennas installed in a BS or the like increases in accordance with the recent communication plan (topologies / network designs), the number of RRHs or equipment connected to the RRH also increases.

    According to various embodiments, the at least one signal distribution block 31 serves to distribute the opto-electric hybrid garter cable 32 in an optical cable and in a power cable inside the RRH 20. The opto-electrical hybrid garter cable 32 may be connected to the opto-electrical hybrid distribution cable 120 by means of a connector structure comprising a connector of an opto-electric hybrid type or the like, which will be described later on. a detailed way.
    According to various embodiments, cables 111 of optical fiber, for transmitting an optical signal, may be arranged in a central region and power cables 112, for transmitting an electrical signal, may be arranged around cables 111 of FIG. fiber optic, in the opto-electric hybrid power cable 110. In another example, the opto-electrical hybrid distribution cable 120 may contain an optical fiber cable 121 having a plurality of optical fibers and a pair of power cables 122 disposed in a partial region of the outer circumferential surface of the cable 121 of optical fiber.
    In one example, each of the optical fiber cables 111 and 121 may comprise a central voltage element, a plurality of tubes 111a or 121a, and a tube assembler 111b or 121b. The central voltage element is disposed at the center of the optical fiber cable 111 and provides a pulling force to the optical fiber cable 111. The plurality of tubes 111a disposed around the central tension member are tubular cylinders and a plurality of optical transmission media may be accommodated in the voids.

    We will describe, below, a precise structure of the enclosure 130 distribution.
    FIG. 2a is an exploded perspective view of an assembly 200 of opto-electric hybrid cable according to various embodiments of the present disclosure and FIG. 2b is an exploded perspective view of the assembly 200 of hybrid opto cable. -electric seen from a direction different from that of Figure 2a.
    Referring to Figures 2a and 2b, the assembly 200 of opto-electric hybrid cable may comprise an opto-electric hybrid power supply cable 210 for transmitting an optical signal and an electrical signal at the same time, an enclosure 230 distribution system for distributing light and power of the opto-electric hybrid power supply cable 210 into a plurality of opto-electric hybrid groups and distributing the opto-electric hybrid groups, and outgoing opto-electric hybrid distribution cables 220 of the enclosure 230 of distribution, then connected to a RRH. The assembly 200 of opto-electric hybrid cable illustrated in FIGS. 2a and 2b may be wholly or partially identical to the assembly 100 of opto-electric hybrid cable illustrated in FIG.
    According to various embodiments, the enclosure 230 distribution comprises a tube-shaped housing. The opto-electric hybrid power supply cable 210 can be inserted into a distribution end 230 and the opto-electric hybrid power supply cable 210, which has been inserted, can be distributed in the distribution enclosure 230 and extend to a plurality of opto-electric hybrid cables 220 in the other end of the distribution enclosure 230.
    According to various embodiments, the enclosure 230 distribution may comprise a housing 231, seals 232 mounted in the housing 231, an optical distribution box 235, elements 233 and 236 support and an element 234 of seal.
    The housing 231 may be formed by cooperating a plurality of shells 231a and 231b distinct (or "supports 231a and 231b"), each being a separate half. The housing 231 may be shaped, for example, as a tube or conduit, both ends of which are open.
    According to various embodiments, the housing 231 may be manufactured in the form of first and second shells 231a and 231b separated, and then completed by cooperating the first and second shells 231a and 231b with each other. The first and second shells 231a and 231b may be injection molded into a polymer (polycarbonate (PC) or poly (ethylene terephthalate) (PET)), sodium salt of polyacrylic acid (PAAS), poly (sulfide of phenylene) (PPS) and polyphthalamide (PPA). The first and second shells 231a and 231b can be made by casting in a zinc shell or casting in an aluminum shell or by treating a metal. In another example, the outer circumferential surfaces of the first and second shells 231a and 231b may be coated with a material resistant to hypersaline water. Thus, for example, the outer circumferential surfaces of the first and second shells 231a and 231b may be coated or plated with a corrosion-resistant material in hypersaline water so as to be able to protect from the atmosphere. ambient electronic parts placed in the first and second shells 231a and 231b.
    According to various embodiments, the opto-electric hybrid cables 210 and 220 cooperate and extend from the open end portions of the housing 231 by forming a pipe structure. Thus, for example, one end of the housing 231 may include a first aperture 231c, in which the opto-electrical hybrid cable 210 is inserted. A mounting surface shaped correspondingly to the shape of the outer circumferential surface of the opto-electric hybrid power cable 210 may be formed along the periphery of the first aperture 231c, so that the cable 210 can be mounted. Opto-electric hybrid power supply on the mounting surface and in cooperation with it. In another example, a mounting surface shaped correspondingly to the shape of the outer circumferential surface of a cooperation between the optoelectric hybrid power supply cable 210 and the sealing member 234 may be formed along the periphery of the first opening 231c.
    According to various embodiments, the other end of the housing 231 may comprise a second opening 231d, in which extend the opto-electric hybrid distribution cables 220, which have been distributed. A mounting surface shaped correspondingly to the shape of the outer circumferential surface of the second support member 236 cooperating with the opto-electrical hybrid distribution cables 220 may be formed along the peripheral of the second aperture 23ld.
    According to various embodiments, the mounting surfaces formed along the peripheries of the first and second openings 231c and 231d may be formed by cooperating the first support 231a with the second support 231b. Thus, for example, semicircular mounting surfaces can be formed on the first and second shells 231 and 231b and a circular opening can be formed by cooperating the shells 231a and 231b with each other. . But, although the openings 231c and 23d and peripheral portions of the openings 231c and 23ld are circular, their shape is not limited to a circle. The openings 231c and 23ld and the peripheral portions of the openings 231c and 231d may thus have various shapes depending on the shapes of the opto-electric hybrid supply cable 210 and / or opto-electric hybrid distribution cables 220.
    According to various embodiments, the housing 231 is configured as an open enclosure type, comprising the first and second shells 231a and 231b, whose cooperation regions correspond. The interior space of the housing 231 can thus be controlled during an operation. As a result, operators can easily find a lack of cooperation of interior parts and intervene quickly, thereby saving energy. Thus, for example, after the opto-electric hybrid power supply cable 210 and the plurality of opto-electric hybrid distribution cables 220 have been mounted or cooperated within the first carrier 231a, the second support 231b can be made to cooperate with the first support 231a. In another example, after the cables inside the opto-electrical hybrid power supply cable 210 have been subdivided into at least one group and the at least one group has been connected to the plurality of hybrid opto distribution cables 220 -electriques, one can cooperate the first shell 231a with the second shell 231b.
    According to various embodiments, it is possible to cooperate the first and second shells 231a and 231b with each other thus forming the outside of the assembly 200 of opto-electric hybrid cable and by reinforcing it. resistance. For example, it is possible to form a plurality of openings or cavities in the first and second shells 231a and 231b depending on the arrangement of electronic parts in the device and that parts in openings or cavities, so as to increase the resistance.
    According to various embodiments, various structures can be formed on the surfaces of the first and second shells 231a and 231b depending on the arrangement of electronic parts in the assembly 200 of opto-electric hybrid cable or in a structure of cooperation between the first and second hulls 231a and 231b. For example, it is possible to form a space for housing the optical distribution box 235 and the plurality of support elements 233 and 236 in each of the first shell 231a and the second shell 231b or by cooperation between the first hull 231a and the second hull 231b. The space for the optical distribution box 235 and the plurality of support members 233 and 236 may be formed in the form of a cavity or rib that surrounds parts. According to various embodiments, cooperating bosses or mutually corresponding cooperation holes may be formed between the first shell 231a and the second shell 231b. Thus, for example, whereas a cooperation element, such as a screw, cooperates with a cooperation element with a cooperation hole, the first shell 231a and the second shell 231b can cooperate with one another. with each other, face to face or with a partial region of each hull housed in. the other hull.
    According to various embodiments, the seals 232 may be arranged along the periphery of the housing 231, to prevent introduction of foreign material. For example, grooves or cavities may be formed to mount the seals 232 to peripheral regions of the first shell 231a and the second shell 231b and the seals 232 may be placed in the cavities to effectively seal the seals. internal space of the housing 231 from the cooperation regions of the first shell 231a and the second shell 231b on the basis of the cooperation mechanism of the first shell 231a and the second shell 231b. The seals 232 may be formed in a closed loop each comprising a pair of curved surfaces. The seals 232 may be of resilient material, thus effectively sealing the interior, while the opto-electric hybrid cable is mounted thereon to the outside.
    According to various embodiments, the enclosure 230 distribution can be arranged around the first opening 231c of the housing 231 and may include the first support member 233 supporting the opto-electric hybrid power supply cable 210 inserted into the first opening 231c.
    The first support member 233 may be configured to include a hollow hole corresponding to an end portion of the opto-electric hybrid power supply cable 210 and support the opto-electric hybrid power supply cable 210, so as to that the opto-electric hybrid power supply cable 210 can be inserted into the hollow hole and thus can not move. In addition, the first support element 233 can support the optical cables coming out of the opto-electric hybrid power supply cable 210, so that they do not move in the optical distribution box 235.
    Thus, for example, that the first support member 233 can be configured into a plurality of segments, and then the segments can cooperate with each other by surrounding an end portion of the power supply cable 210 Opto-electric hybrid. The first and second shells 231a and 231b may be provided with grooves, in which the first support element 233 is mounted, and thus the first support element 233, cooperating with the optoelectric hybrid power supply cable 210, can be mounted fixed in the grooves.
    According to one embodiment, while the first support element 233 is shaped in a square and configured as separate elements, the first support element 233 is not limited to this precise configuration.
