DETAILED DESCRIPTION
[0033] Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0034] The present disclosure is directed to a communications panel 100 (e.g., for telecommunications) including a chassis 114 that mounts to a standard rack (e.g., in a data center). For example, brackets B may be disposed at opposite first and second sides 106, 108 of the chassis 114 to attach the chassis 114 to the rack. The chassis 114 extends along a depth D between a front 102 and a rear 104, along a width W between the opposite sides 106, 108, and along a height H between a top 110 and a bottom 112. Front ports 116 are accessible from the front 102 of the chassis 114. A cable entrance location 118 (
[0035] A feeder cable F can enter an interior 115 (
[0036] In certain implementations, groups S of fibers of the feeder cable F can be separated out after extending through the cable entrance location and routed to respective fanout holders 125 (e.g., see
[0037] In certain implementations, an anchoring station 120 is disposed at the rear 104 of the chassis 114 (e.g., see
[0038] In certain implementations, the one or more anchor members 130 are coupled to a mounting bracket 124, 224 that is movable relative to the chassis 114 to carry the anchor members 130 between at least two configurations. In the first configuration, the anchor members 130 are positioned relative to the chassis 114 to define a first cable routing path extending in a first direction to the cable entrance location 118 (e.g., see
[0039] Advantageously, the feeder cable F can be pre-anchored to the mounting bracket 124, 224 at a factory during cabling of the chassis 114. Pre-anchoring the cable F allows the internal ports 117 of the chassis 114 to be populated in the factory. An end user then installs the pre-populated chassis 114 and pre-anchored feeder cable F at an installation site. The anchor members 130 protect the connectorized ends of the cable F from pulling out of the internal ports 117 during shipping and/or installation. The movable mounting bracket 124, 224 allows the end user to select which cable routing path is desirable from the feeder cable F. For example, the movable mounting bracket 124, 224 allows the pre-anchored feeder cable F to be routed to the cable entrance location 118 from the first side 106 of the chassis 114 or from the second side 108 of the chassis 114.
[0040] The mounting bracket 124, 224 carries the anchor members 130 along a controlled path P (
[0041] In certain implementations, the anchor station 120 includes a support ledge 122 that extends outwardly from the chassis 114. In certain implementations, the mounting bracket 124, 224 is coupled to the support ledge 122. In certain examples, the pivot axis A extends through the support ledge 122. In certain implementations, a cover 126 can be mounted to the support ledge 122 to cover the end portion of the feeder cable F. The cover 126 may cooperate with the ledge 122 to form a passage extending between opposite side openings 128. The mounting bracket 124, 224 can be positioned relative to the support ledge 122 to define each of the first and second cable routing paths through the passage to a respective one of the side openings 128.
[0042] In certain implementations, the chassis 114 and mounting bracket 124, 224 include aligning elements that aid in securing the mounting bracket 124 to one of the pre-determined mounting positions. In certain examples, the chassis 114 defines slots 129 and the mounting bracket 124, 224 includes tabs 139 that fit within the slots 129. When the mounting bracket 124, 224 is disposed at the first pre-determined mounting position, a first of the tabs 139 extends into a first slot 129 in the rear wall of the chassis 114 (e.g., see
[0043]
[0044] In certain implementations, the body 131 is configured to be secured in one of the pre-determined mounting positions. For example, the body 131 may define fastener apertures 137 that align with the fastener apertures 132 at the pre-determined mounting positions to allow the fasteners 134 to extend therethrough. In certain examples, the body 131 defines a first set of fastener apertures 137 that align at the first pre-determined mounting position and a second set of fastener apertures 137 that align with the second pre-determined mounting position (e.g., compare
[0045]
[0046] In certain implementations, the body 231 is configured to be secured in one of the pre-determined mounting positions. For example, the body 231 may define fastener apertures 137 that align with the fastener apertures 132 at the pre-determined mounting positions to allow the fasteners 134 to extend therethrough. In certain examples, the body 231 defines a first set of fastener apertures 137 that align at the first pre-determined mounting position and a second set of fastener apertures 137 that align with the second pre-determined mounting position.
[0047] In certain examples, the body 231 includes a planar surface extending along a length of the body 231 from the aperture 233, past the mounting region 235, to the fastener apertures 137. In certain implementations, the body 231 includes opposing sidewalls 239 that extend along the length of the body 231. The sidewalls 239 may aid in retaining the fibers and/or cable on the mounting bracket 224 during movement of the mounting bracket 224. In certain examples, the tabs 139 extend laterally outwardly beyond the sidewalls 239.
[0048] Referring to
[0049] In certain implementations, the cable entrance location 118 is elongate along the width of the chassis 114. The width of the cable entrance location 118 accommodates movement of the cable F along the controlled path P. In certain implementations, the cable entrance location 118 is formed at an open end of a cable guide 140. The cable guide 140 extends into the interior 115 of the chassis 114 to guide the feeder cable F. A cable guide 140, 240 provides bend radius protection to the feeder cable F even while the pre-anchored cable is being moved with the mounting bracket 124 to a pre-determined mounting position. In particular, the cable guide 140, 240 provides bend radius protection when the cable F and anchor station 120 are disposed in the first position and provides bend radius protection when the cable F and anchor station 120 are disposed in the second position.
[0050]
[0051] In certain implementations, the feeder cable F is loose within the cable guide 140. Accordingly, the feeder cable F can slide within the passage 148 of the cable guide 140 during movement of the cable bracket 124 and the anchor members 130 along the controlled path P. The mounting bracket 124 is configured so that the controlled path does not lead to sufficient sliding of the cable F to apply a pulling force on the connectorized ends disposed at the internal ports 117.
[0052]
[0053] In certain implementations, the cable guide 240 routes the feeder cable F from a first height level to a second height level as the cable extends along the passage 248. For example, the wider axial end 245 of the passage 248 may be raised by a distance R relative to the narrower axial end 243. Accordingly, the raised end 245 clears a bottom portion of the rear chassis wall 127 while the narrower end 243 transitions the feeder cable F onto the bottom of the chassis 114 (e.g., see
[0054] In certain implementations, the cable guide 240 includes a first piece 242 and a second piece 244 that cooperate to define the internal passage 248. In certain examples, the bend radius limiters 246 are defined by the first piece 242. In the example shown, the first piece 242 defines an open-topped channel extending between the narrower end 243 and the wider end 245. The second piece 244 mounts to the first piece to close the open top of the channel to form the internal passage 248. In certain examples, the first piece 242 and second piece 244 are formed from different materials (e.g., the first piece 242 being formed from plastic while the second piece 244 is formed from metal).
[0055] In other implementations, opposing radius limiters can be used instead of a cable guide 140, 240. For example, a first radius limiter may extend into the chassis 114 from a rear entrance while curving in a first direction and a second radius limiter may extend into the chassis 114 from the rear entrance while curving in a second direction that is opposite the first direction. In some examples, the first and second radius limiters can be separate pieces that are separately mounted to the chassis 114. In other examples, the first and second radius limiters can be monolithically formed or separate pieces mounted to a common base.
[0056] In accordance with certain aspects of the disclosure, pre-cabling the internal ports 117 of the chassis 114 at the factory allows the chassis 114 to hold the internal ports 117 in a dense configuration that need not provide finger access to the end user for each internal port 117. Accordingly, pre-cabling the chassis 114 at the factory allows a 5RU chassis 114 to hold at least 432 internal ports 117. In certain examples, the chassis 114 can hold at least 576 internal ports 117 within a 5 RU space. In certain examples, the chassis 114 can hold at least 864 internal ports 117 within a 5 RU space (e.g., see
[0057] In some implementation, the internal ports 117 are formed by optical adapters having aligned external (e.g., front) ports 116. In some examples, the internal ports 117 are single-fiber ports. In an example, the internal ports 117 are LC ports. In another example, the internal ports 117 are SC ports. In other examples, the internal ports 117 are multi-fiber ports (e.g., MPO ports). In other implementations, the internal ports 117 are electrical sockets or electrical contacts for receiving wires of the feeder cable F.
[0058] As shown in
[0059] As shown in
[0060] In certain implementations, the front face 152 of the frame 150 includes first and second angled sections 162, 164 that meet at an apex 160 at an intermediate location along the width W of the chassis 114. In the example shown, the first and second angled sections 162, 164 have a common length and the apex 160 is disposed at a center of the width W of the chassis 114. The first and second sections 162, 164 extend inwardly and forwardly from the sidewalls of the chassis 114 to the apex 160. In certain examples, the frame 150 forms a v-shape. Angling sections of the front face 152 increases the surface area at which the ports 116, 117 can be disposed compared to a front face extending straight along the width of the chassis 114.
[0061] In some implementations, the apertures 154 at the first angled section 162 are laterally aligned with the apertures 154 of the second angled section 164 along the width W of the chassis 114. In other implementations, the apertures 154 of the first angled section 162 are offset towards the top 110 or bottom 112 of the chassis 114 relative to the apertures 154 of the second angled section 164. In certain examples, the offset is less than the vertical height of one of the front ports 164. In certain examples, the offset is less than 0.1 inches. In certain examples, the offset is less than 0.09 inches. In certain examples, the offset is about 0.08 inches. In an example, the offset is about 0.08 inches.
[0062] In certain implementations, the chassis 114 includes a front cover 166 that selectively extends across an open front of the chassis 114. The front cover 166 blocks access to the front ports 116 when the front cover 166 extends across the open front of the chassis 114. In some examples, the front cover 166 pivots to an open position to expose the front ports 116. In other examples, the front cover 166 is removable from the chassis 114. When the front cover 166 is disposed in the blocking position, the front cover 166 is spaced from the apex 160 of the frame 150 by a gap G (
