    A telecommunications frame (100) includes a frame body (101) defining a restricted region (130). A plurality of splice trays (132) are disposed in the restricted region (130) and a bounding wall arrangement (140) separating the restricted region (130) from other regions of the frame body (101). A door (135) covers the restricted region (130) to inhibit user access to the restricted region (130) when the door (135) is closed. The frame body (101), bounding wall arrangement (140), and door (135) cooperate to inhibit user access to the restricted region (130). The bounding wall arrangement (140) includes at least one section (141) that is removable to provide an open gap (142) through which splice trays (132) within the restriction region (130) may be accessed without moving the pivot axes (P) of the splice trays (132).

    DESCRIPTION
    Region for isolated joints, with removable wall Background
    In the telecommunications industry, the use of fiber optic cables to transport transmission signals is spreading rapidly. Fiber distribution racks have been adapted to help connect fiber optic equipment. In order to connect fiber optic equipment in the fiber distribution frame, or to connect fiber optic equipment between fiber distribution racks, fiber optic cable is arranged routed between the fiber optic equipment and / or the distribution racks fiber For example, feeder cables can be routed to the rack from an optical signal source; distribution cables can be routed from the racks to the subscriber equipment; and connection cords can be routed between racks or between equipment located within a rack.
    One or more coupler modules (eg termination modules, splice modules, etc.) may have been mounted on the frame as fiber optic equipment. In some implementations, one or more termination modules (eg, connection panels) are mounted on the frame. The ends provided with a connector, belonging to intermediate fibers, can be plugged into rear doors or adapters of the termination modules, and routed to splice trays for connection with the feeder and / or distribution fibers. The ends provided with a connector, belonging to the connection cords, can be plugged into the front doors of the adapters. Typically, the connections made by the connection cords are intended to be temporary or modified, while the connections made in the splice trays are intended to be more permanent or fixed.
    Further development in fiber distribution frame systems is desirable. Compendium
    Aspects of the present invention relate to a telecommunications frame that includes a frame body, which has an interior accessible through an open front part. The interior of the frame body defines a confined region. A boundary wall arrangement is coupled to the body of the frame in order to separate the confined region from the rest of the frame. The border wall arrangement and the body of the frame cooperate to make it impossible for a user to access the confined region through the rear, the top, the bottom, a first side and a second side of the confined region . The border wall arrangement includes at least one section that is removable from the border wall arrangement while leaving a remaining portion of the border wall arrangement intact. The frame also includes a door configured to move between a closed position and an open position. The confined region is accessible through the open front of the frame body when the door is in the open position. The door has been sized and shaped to cover the confined region so as to prevent access by a user to the confined region through the open front of the frame body, when the door is in the closed position.
    In some implementations, a plurality of splice trays have been arranged in the confined region. Each of the splice trays is mounted within the confined region so that it pivots around a respective pivot axis. The border wall arrangement and the door prevent access by the user to the trays for joints arranged within the confined region, respectively when they are intact and closed.
    In certain implementations, the frame also defines a coupling region and / or a storage region.
    Other aspects of the present invention relate to a method for accessing splice trays within a confined region of a telecommunications frame. The confined region is separated from the rest of the frame by a boundary wall arrangement. The method includes opening a door to provide access to the confined region through a front opening of the frame; disassemble at least a portion of the border wall arrangement; and sliding the portion of the boundary wall arrangement forward through the front opening of the frame, in order to provide the user with access to the splice trays through an open side of the confined region. The method also includes accessing the splice trays without moving the pivot axis of any of the splice trays with respect to the frame.
    Retaining the pivot axes of the splice trays in fixed positions with respect to the frame protects the optical fibers / cables laid to and from the splice trays. Moving the pivot axes could cause tension in the optical fibers / cables or bend the optical fibers / cables or bend the optical fibers / cables beyond an appropriate radius of curvature, which can lead to damage to the optical fibers / cables or may otherwise lead to optical signal losses.
    A variety of additional aspects will be presented in the description that follows. These aspects may refer to individual characteristics and combinations of characteristics. It should be understood that both the above general description and the following detailed description are only by way of example and explanatory, and are not limitative of the broad concepts on which the embodiments disclosed herein are based.

    Reference will now be made in detail to the exemplary aspects of the present invention that have been illustrated in the accompanying drawings. Whenever possible, the same reference numbers will be used throughout all the drawings to refer to the same or similar structure.
    In general, a telecommunications frame defines an interior that is accessible through an open front part. The interior of the frame defines a confined region. A boundary wall arrangement is coupled to the body of the frame in order to separate the confined region from the rest of the frame. The boundary wall arrangement and the body of the frame cooperate to prevent access by a user to the confined region. The boundary wall arrangement includes at least one section that is removable from the boundary wall arrangement in order to provide an open separation space through which user access to the confined portion can be provided.
    Before the boundary wall section is removed, a user can access the splice trays through the front of the confined region, between the boundary wall arrangement and one side of the frame body. Once the border wall section has been removed, the user can also insert an arm / hand through the open separation space.
    One or more splice trays may have been arranged within the confined region. It is possible to access the splice trays by disassembling at least one section of the boundary wall arrangement; and sliding the section of the boundary wall arrangement forward, through the open front of the frame, in order to provide the user with access to the splice trays through the open side of the confined region. The method also includes access to the splice trays without having to move the pivot axis of any of the splice trays with respect to the frame. For example, splice trays can be accessed without having to move the trays laterally.
    In certain implementations, the frame also includes a door configured to move between a closed position and an open position. The confined region is accessible through the open front of the frame body, when the door is in the open position. The door has been sized and shaped to cover the confined region to prevent the user from accessing the confined region through the open front of the frame body, when the door is in the closed position. In such implementations, the method of access to the splice tray includes opening the door to provide access to the confined region through a front opening of the frame, before removing the section of the boundary wall arrangement.
    Figures 1 and 2 illustrate an exemplary provided implementation of a telecommunications frame 100 that includes a frame body 101, which defines an interior 108 and which has an open front part 102, a rear part 103, an upper part 104 , a lower part 105, a first side 106 and a second side 107. The interior 108 of the frame body 101 defines a confined region 130 that is separated from the rest of the interior 108 of the frame. In some implementations, the interior 108 of the frame also defines a coupling region 110 and / or a storage region 112. In certain implementations, the coupling region 110 is disposed above the confined region 130, and the storage region 112 it extends side by side with both the coupling region 110 and the confined region 130. In other implementations, regions 110, 112, 130 may have been arranged in any desired configuration.
    One or more coupler modules (eg termination modules and / or splice modules) 111 may have been arranged in the coupling region 110. Each coupler module 111 has been configured to optically couple with at least two optical fibers. In certain implementations, each coupler module 111 has been configured to mate with multiple pairs of optical fibers. In an exemplary implementation provided, the coupler module 111 includes a termination module. In another implementation provided by way of example, the coupler module 111 includes a splice tray. One or more cable storage structures 113 (for example, reels, spool halves, radio limiters) may have been arranged in the storage region 112. The cable storage structures 113 guide the optical cables (i.e., or fibers). ) through the interior 108 of the frame, they organize the cables / fibers and / or prevent the cables / fibers from bending excessively. One or more trays 132 may have been arranged for splices within the confined region 130, as will be explained in greater detail herein.
    The body 101 of the frame defines one or more doors 109 for cables through which one or more fiber optic cables can be routed within the body 101 of the frame. In certain implementations, the body 101 of the frame defines at least one cable door 109 located in the upper part 104 of the body 101 of the frame, and at least one cable door 109 located in the lower part 105 of the body 101 of the frame. In the example shown, the frame body 101 defines a first upper cable door 109a, a second upper cable door 109b and a lower cable door 109c. Additionally, cable doors can also be defined by the body of the frame (for example, a cable door through which connection cords can be routed to adjacent frames).
    One or more cable routing paths extend between the various sections of the interior 108 of the frame. For example, one or more vertical routing paths can extend from the cable doors 109 to the rest of the interior 108 of the frame. In some implementations, the interior 108 of the frame includes one or more exterior vertical paths 114. The exterior paths 114 extend from the first and second doors for upper cables 109a, 109b to the lower part 105 of the body 101 of the frame. For example, a first outer path 114 extends along the first side 106 of the body 101 of the frame, and a second outer path 114 extends along the second side 107 of the body 101 of the frame.
    In some implementations, the interior 108 of the frame includes one or more interior vertical paths 115. In certain implementations, a first interior vertical path 115 extends between the storage region 112 and the coupling region 110. In the example shown, the first Inner vertical path 115 also extends between the storage region 112 and the confined region 130. A second interior vertical path 115 extends along an opposite side of the confined region 130 and / or the coupling region 110. Some retention fingers 116 are arranged along the lengths of the outer paths 114. As shown in Figure 1, a first type of retention fingers 116a may have been disposed within the second outer path 114, and a second type of retention fingers 116b may have been arranged within the other paths 114, 115. In other implementations, however, it may have Leave any desired type of cable retainer within any of the routing paths 114, 115.
    The cables can be routed to the inside of the frame 100 from any of the doors 109. The cables entering the body 101 of the frame from the first cable door 109a are routed vertically down through the first outer cable path 114, around a curvature radius limiting arrangement 117, and vertically upwardly along the first inner cable path 115, to the coupling region 110. The ends provided with connectors, belonging to the cables, can be plugged into doors adapters located in the coupling region 110. A loose, or excess, length of the cables may be wound around reels 113 arranged in the storage region 112, which is located between the outer and inner paths 114, 115.
    The cables entering the body 101 of the frame from the second cable door 109b are routed vertically down through the second outer cable path 114, and back up, along the second inner cable path 115, to the confined region 130 and / or the coupling region 110. In some implementations, the ends devoid of connectors of one or more of the cables may be routed to the trays 132 for splices located within the confined region 130. In other implementations , the ends provided with connectors of other cables may be routed beyond the confined region 130, to the coupling region 110, in which the ends provided with connectors can be plugged into adapter doors.
    The cables entering the body 101 of the frame from the third cable door 109c (Figure 3) are routed vertically upwards, into the confined region 130. The ends devoid of connectors, belonging to the cables, can be coupled to other cable ends devoid of connectors, trays 132 located for splices arranged in the confined region 130. In certain implementations, the ends provided with connectors of one or more cables entering the body 101 of the frame through a door 109c for cables, they can be routed around curvature radius limiters 117 and into the second inner path 115, to the coupling region 110, for connection to the adapters. In other implementations, the ends devoid of connectors and belonging to the cables entering from any of the doors 109, are routed to the coupling region 110 for optical coupling to other fibers through a splice housing or other coupling members .
    In some implementations, one or more main doors can be coupled to the body 110 of the frame to move between open and closed positions. Each door covers, at least partially, the interior 108 of the frame when it is in the closed position. In certain implementations, the doors can be locked or otherwise secured releasably in the closed positions. In some implementations, a first main door 118 and a second main door 119 are pivotally coupled to the body 101 of the frame. In the example shown, the first main door 118 has been configured to cover at least the coupling region 110 when it is closed, and the second main door 119 has been configured to cover at least the coupling region 122 when it is closed. As shown in Figures 1 and 2, the first main door 118 is shorter than the second main door 119, as will be discussed in greater detail below.
    Figures 3-6 are enlarged views of the confined region 130 of the frame 100, from which several components have been removed so that region 130 is more easily seen. As seen in Figure 2, one or more limiters may have been arranged 117 of curvature radius in the confined region 130. Non-limiting examples of curvature radius 117 limiters include storage reels, partial reels and curved panels. In the example shown, two partial reels and a horizontal panel curved upwards from their opposite sides have been arranged in the confined region 130. In addition, a plurality of trays 132 may have been arranged for splices in the confined region 130. As shown in Figure 6, splice trays 132 may have been mounted on one or more brackets 131 that are fixedly mounted on body 101 of the frame. In the example shown, splice trays 132 are mounted between two triangular brackets 131 that are fixedly mounted at the rear 103 of body 101 of the frame.
    Each splice tray 132 has been configured to pivot along a pivot axis P (Figure 2), with respect to the bracket 131 and / or with respect to the body 101 of the frame. In the example shown, splice trays 132 pivot between a removed, non-operative position, in which an upper part of the tray 132 faces the rear part 103 of the body 101 of the frame, and an accessible position, in which the upper part of the splice tray 132 is generally facing upwards, in the direction of the upper part 104 of the frame body 101. Of course, in certain implementations, splice trays 132 may be partially angled forward when they are in the accessible position. The trays 132 for splices can be retained in the removed, non-operative positions, until access is desired. In the example shown, two tapes 133 are wrapped around splice trays 132 and joined together (for example, using Velcro®). In other implementations, a single tape may be arranged wrapped around the trays 132, or the tray 132 may be held in place using a magnet, a hitch or other retention structure.
    In the example shown, splice trays 132 are positioned in such a way that the pivot axis P of each tray 132 extends between the first side 106 and the second side 107 of the frame body 101 (see Figure 2) . As shown in Figure 6, the trays 132 for splices are staggered vertically in such a way that the pivot axes P define a plane that is angled with respect to the upper part 104, the lower part 105, to the front 102 and to the rear 103 of the body 101 of the frame. For example, the pivot axis P1 of a first splice tray 132 is located below and in front of the pivot shaft P2 of a second splice tray 132 mounted on the brackets 131. Such a configuration allows access to a tray 132 for splices located towards the rear part 103 of the stack, by means of the forward and downward pivoting movement of that splice tray 132 and any trays 132 for splices located in front of it, from the removed, non-operative positions, to the accessible positions .
    A door 153 is pivotally coupled to the body 101 of the frame to move between a closed position and an open position. The door 135 has been sized and shaped so as to cover the confined region 130 in order to prevent user access to the trays 132 for splices arranged within the confined region 130, through the open front part 102 of the body 101 of the frame, when the door 135 is in the closed position. The confined region 130 is accessible through the open front part 102 of the body 101 of the frame when the door 135 is in the open position. In the example shown, the door 135 has a height H (Figure 1) that is substantially the same value as that of the confined region 130. As shown in Figures 1 and 2, the heights of the door 135 and the First main door 118, combined, are approximately equal to the height of the second main door 119.
    Door 135 has been configured to be retained in the closed position. For example, the door 135 includes a first locking mechanism 136 that secures the door 135 to the body 101 of the frame and / or to the boundary wall arrangement 140. For example, the first locking mechanism 136 may include a rotating flange that moves behind a portion of the body 101 of the frame and / or the boundary wall arrangement 140, as will be explained in more detail below. In certain implementations, the door 135 also defines a locking opening 137 that aligns with a locking flange 134 coupled to the body 101 of the frame and / or to the boundary wall arrangement 140. A fastener (for example, a screw) it may have been inserted through opening 137 and secured (for example, threaded) to locking flange 134.
    By limiting access to the confined section 130, connections between more permanent fibers (or what is the same, less temporary) (for example, in splice trays 132) can be protected (for example, from improper handling), while providing access to more temporary (i.e. less permanent) connections between fibers (for example, in coupler modules 111). Accordingly, in certain implementations, a less skilled technician may be allowed to access the coupling region 110 of the interior 108 of the frame, in order to adjust plug-type connections in the termination modules 111, while being prevents adjusting the existing optical splices in trays 132.
    As shown in Figures 1-3, the confined region 130 is separated from the interior 108 of the frame body (for example, from the storage region 112 and / or the coupling region 110) by a boundary wall arrangement 140 provided by way of example, coupled to the body 101 of the frame. The boundary wall arrangement 140 and the body 101 of the frame cooperate to make it impossible for the user to access the trays 132 for joints arranged within the confined region 130, through the rear, the top, the bottom, the first side and the second side of the confined region 130. The boundary wall arrangement 140 cooperates with the door 135 to prevent access to the confined region 130, while providing access to the coupling region 110 and / or the region of storage 112. In some implementations, the boundary wall arrangement 140 defines a periphery around the confined wall 130. In other implementations, however, the boundary wall arrangement 140 extends along only part of the periphery of the region confined 130. In such implementations, the ends of the boundary wall arrangement 140 are sufficiently closed with the body 101 of the frame so that the body 101 of the frame effectively prevents user access to the confined region
    130.
    For example, in Figure 3, the boundary wall arrangement 140 extends along a first side of the confined region 130 and along an upper part of the confined region 130, thereby preventing access by the user to splice trays from the first side and the upper part of the confined region 130. The boundary wall arrangement 140 does not extend along the second side, the bottom or the back of the confined region 130 However, the second side 107 of the body 101 of the frame is located close enough to the confined region 130 to make it impossible for the user to access the trays 132 for splices from the second side; the lower part 105 of the body 101 of the frame is located close enough to the confined region 130 to prevent the user from accessing the trays 132 for splices from the bottom; and the rear part 103 of the body 101 of the frame prevents access to the confined region 130 from the rear part of the confined region.
    The density of the frame 100 (ie, the number of fibers / cables that may have been disposed within the frame 100) may be important in certain applications. To facilitate that a sufficient number of cable routing paths 114, 115 of sufficient thickness is provided, the confined region 130 of certain frame bodies 101 may have a narrow width W (Figure 2). For example, in certain implementations, the boundary wall arrangement 140 has been placed in such a way that the width W of the confined region 130 is large enough to allow splice trays 132 to be disposed within the confined region. 130, but also small enough to prevent a user from sliding their hands through the confined region 130, towards the rear wall 103 of the body 101 of the frame. For example, the boundary wall arrangement 140 and / or the side wall 107 of the frame body 101 may have been placed too close to the sides of the splice trays 132. Accordingly, the boundary wall arrangement 140 of certain frame bodies 101 may limit access to one or more trays 132 for splices (eg, trays 132 for splices located toward the rear of the stack of splice trays ).
    The boundary wall arrangement 140 includes at least one section 141 that is removable from a remaining part of the boundary wall arrangement 140, while leaving the remaining portion of the boundary wall arrangement 140 intact. The removable section 141 leaves a Open separation space 142 in the boundary wall arrangement 140 when section 141 is removed. The open separation space 142 provides the user with access to the confined region 130 (for example, to trays 132 for joints disposed within the confined region) through the open separation space 142 (see, for example, in Figure 6 ). In the example shown, the removable section 141 leaves an open separation space 142 extending along the first side of the confined region 130. In other implementations, the removable section 141 may leave an open separation space 142 along on any desired side of the confined region 130. In certain implementations, the open separation space 142 extends vertically at least along the height of the stack of splice trays. In the example shown, the open separation space 142 extends along the stack of splice trays and below it to provide access to the curvature radius limiters 117 arranged in the confined region 130.
    In the example shown, the boundary wall arrangement 140 includes a first panel 143 that extends at least partially along the first side of the confined region 130, and a second panel 147 that extends at least partially along the upper part of the confined region 130. In certain implementations, a third panel 149 also extends along the first side of the confined region 130. As shown in Figures 3 and 4, the first panel 143 is coupled so detachable to the second and third panels 147, 149. In certain implementations, the first panel 143 is removably coupled to the second and third panels 147, 49 using screws or other removable / releasable fasteners 150.
    In some implementations, the first panel 143 includes a first front flange 144 through which a fastener can be inserted and secured to at least one of the other panels 147, 149. In certain implementations, the first locking mechanism 136 It is configured to selectively engage with the first front flange 144 or with the first panel 143 to retain the door 135 in the closed position. For example, the front flange 144 can be attached to the first flange 148 of the third panel 149. In certain implementations, the first panel 143 also includes a second front flange 146 through which a fastener can be inserted and secured to the minus one of the other panels 147, 149. In the example shown, the first front flange 144 is secured to the third panel 149 and the second front flange 149 is secured to the second panel
    147. In certain implementations, the first panel 143 also includes an upper flange 145 that has been configured to sit on a portion of the second panel 147.
    In some implementations, the locking flange 134 for the door 135 extends from the second panel 147 (see, for example, Figure 3). In certain implementations, a curvature radius limiter 117 extends upward from the second panel 147 (see Figure 3). In some implementations, the third panel 149 is disposed in an elevated position with respect to the lower part 105 of the frame body 101, in order to allow the access of the cables into the confined region 130 through the lower part on the first side of the confined region 130. The third panel 149 is located, however, close enough to the lower part 105 of the frame to prevent user access to the confined region through the gap between the third panel 149 and lower part 105 of the frame. In other implementations, the third panel 149 extends to the lower part 105 of the frame, but defines an opening 151 (Figure 4) that provides the cable access to the confined region 130 (for example, from the first inner path 115 and / or from storage region 112). A cover panel 152 may have been removably mounted on the third panel 149 to close the opening 151 when cable access is not desired.
    Referring now to Figures 3-6, there is illustrated an exemplary procedure for accessing trays 132 for splices located within telecommunications frame 100. The procedure includes opening door 135 to provide access. to the confined region 130 through the open front part 102 of the body 101 of the frame. In certain implementations, the door 135 is initially secured in the closed position and the procedure includes unlocking the door 135 before opening the door 135. To unlock certain types of doors 135, a user can rotate the locking mechanism 136. In order If certain types of doors 135 are unlocked, a user can undo the door 135 of the boundary wall arrangement 140 and / or the body 101 of the frame.
    The method of accessing the trays 132 for splices also includes dislodging at least a section 141 of the boundary wall arrangement 140 with respect to the rest of the boundary wall arrangement 140; and extracting section 141 of the boundary wall arrangement 140 to leave an open separation space 142 leading to the confined region 130. In some implementations, the mismatch of the removable section 141 includes unscrewing the removable section 141 from the rest of the arrangement of wall 140. In some implementations, removal of section 141 includes sliding section 141 of boundary wall arrangement 140 forward, through the open front portion 102 of body 101 of the frame, in order to provide access by the user to the confined region 130 through the open separation space 142. For example, the upper flange 145 of the first panel 143 of the boundary wall arrangement 140 can be slid along the upper surface of the second panel 147 as the first panel 143 is being removed from the rest of the boundary wall arrangement 140.
    The method also includes accessing at least one of the trays 132 for splices located within the confined region 130, without having to move the pivot axis P of any of the trays 132 for splices with respect to the portion 101 of the body. Retaining the pivot axes P of the trays 132 for splices in fixed positions with respect to the body 101 of the frame protects the optical fibers / cables routed to and from the trays 132 for splices. The movement of the pivot axes P could cause tensions in the optical fibers / cables or bend the optical fibers / cables beyond an appropriate radius of curvature, which can lead to damage to the optical fibers / cables or may otherwise mode, lead to optical signal losses.
    For example, with the first panel 143 removed, a user can extend a first arm through the open front of the confined region 130 and a second arm through the open side separation space 142 of the confined region 130, with the in order to access trays 132 for splices.
