Description

AREA

[0001] The present disclosure relates generally to fiber optic telecommunications equipment. In particular, the present disclosure relates to fiber optic telecommunications fiber management housings and routing structures. BACKGROUND

[0002] In fiber optic telecommunications and data centers, very small form factor (VSFF) connectors and adapters have helped increase fiber density to as high as 288 fibers per rack unit (RU). However, despite significant fiber density increases by data centers and developers, patch cord and cable management remain a challenge, becoming increasingly so as fiber density grows.

[0003] Furthermore, fiber optic management equipment and modules added to existing data racks and storage may require additional space and volume beyond the rack unit that provides the fiber optic density, which may generally not be available.

[0004] Therefore, devices, modules, and systems for patch cable and fiber optic management would be useful and advantageous. Furthermore, a telecommunications data rack panel that addresses one or more of the aforementioned problems would be beneficial and useful. SHORT DESCRIPTION

[0035] By now focusing on the Fig. Reference is made to Figure 7-23. In embodiments of the adjustment arm assembly 120, they are configured to receive and support the fiber management tray 160 at the second mounting interface 123. In various embodiments, the second mounting interface 123 includes a guide element 167, for example, a pin, which can be inserted into a slot 166 on the fiber management tray 160. The second mounting interface 123 includes an opening 165 configured to receive a fastening element 164, for example, a pin, a clip, or a spring-loaded device, which can be inserted into the opening 165 on the fiber management tray 160. For example, the tray 160 may include a post 168 on which the slot 166 and the element 164 are positioned.

[0036] In some embodiments, the fastening element 164 includes a spring-loaded device (e.g. a spring-loaded screw) to facilitate the mounting or dismounting of the tray 160 on / from the second sleeve 126 of the adjusting arm assembly 120.

[0037] With reference to Fig. 21 The shelf 160 can have a substantially flat or laterally extending platform 161. With reference to Fig. 22-23 the shelf 160 can include a V-shaped or notched platform 161, which can, for example, form an enlarged opening area between the platform 161 and the body 110.

[0038] In various embodiments, an opening 162 is formed in the platform 161 to accommodate a cable management guide 140. With reference to the Fig. Figures 23-24 show an embodiment of a cable management guide 140. The guide 140 comprises an insert element 142 configured to project into the opening 162. The element 142 may include plugs, teeth, or snap-fit ​​devices configured to bend and flex at the edges or perimeter of the platform 161 at the opening 162. The guide 140 comprises multiple walls 148 forming a guide frame 144, including a base wall 146 from which the element 142 extends. The side walls 148 form a region 147 within which cables can be guided for fiber optic routing management.

[0039] Referring to the Fig. 24 to 25, at least one side wall 148 forms a passage 143 through which a user can route cables to and from the area 147. The side walls 148 include a deformable, elastic, or pivotable wall 145 configured to allow the passage 143 in the side wall 148 to open. For example, the passage 143 can form a lateral entrance through the frame 144 into or from the area 147.

[0040] By now focusing on the Fig. Reference is made to figures 26-32. In some embodiments, at least one side wall 148 is movable to form an optionally pivotable wall 145, which allows cables to enter and exit the area 147. The side wall 148 may have an opening 155 into which a bar 153 at the end of an adjacent side wall 148 may project. For example, the bar 153 may form a curved, hook-shaped, or L-shaped end of a deformable wall 145, as shown, for example, in the following. Fig. Figures 30-32 show the frame 144 having a notch 151 on its side walls 148. The notch 151 forms at least one of the side walls 148 as a pivotally hinged wall 145 to selectively open the passage 143 and provide access to the area 147. For example, the notch 151 facilitates bending or flexing the pivotally hinged side wall 145 from a closed position (e.g., Fig. 25, Fig. 27) into an open position (e.g. Fig. 26).

[0041] With reference to Fig. 29, and what's next in the Fig. As shown in Figures 6A-6B, in some embodiments an upper wall 149 of the side walls 148 may have an opening 159 (e.g., an opening in the upper wall) configured to receive an element 142 from a vertically adjacent cable management guide 140 and / or platform 161. For example, the opening 159 may be aligned with an opening 162 on the platform 161. A cable management guide 140 and a platform 161 of a vertically adjacent arrangement (e.g., Fig. 6A-6B) can allow the element 142 to extend into the opening 159 on a vertically lower frame 144 or the vertically lower platform 161 or into both.

[0042] By now focusing on the Fig. Reference is made to Figures 33-34, which provides an embodiment of a hinge arrangement 190. Embodiments of the hinge arrangement 190 can form a torque-locking hinge. With reference to the Fig. 33-34, and as in Fig. As shown in Figure 4B, the hinge assembly 190 comprises a first arm 191 and a second arm 192. Mounting interfaces 193 and 194 are provided on the respective arms 191 and 192. The first mounting interface 193 includes mounting openings 197 configured to connect to the second mounting interface 123 on the adjustment arm assembly 120. The second mounting interface 194 includes mounting openings 196 configured to connect to a door 170. Fig. 1-6B). The hinge arrangement 180 may include a spring-loaded device 195 to limit the speed at which the door 170 can pivot into the open or closed position, for example to enable a ‘soft’ opening or closing.

[0043] Referring to Fig. In some embodiments, the arm 192 is positioned such that no part of the arm 192 or of a wall extends along a larger length dimension of the fastening interface 194. For example, the larger length dimension may essentially correspond to the extension of the door 170 along the vertical direction V in the closed position. The arm 192 is attached to the fastening interface 194 from a proximal end to avoid forming a wall against which a cable could be pinched or trapped.

[0044] Embodiments of the adjusting arm assembly 120 can be configured to allow optional articulated movement along the depth direction D and to provide for the load bearing of the fiber management tray 160, the door 170 and the mass of the cables guided by the cable management guides 140 on the tray 160.

[0045] In various embodiments, door 170 can include a label 171 that is optionally removable from door 170. Door 170 can include hems, pins, notches, slots, or rails in which the label 171 can be positioned for attachment to door 170. In some embodiments, the label 171 includes an adhesive configured for attachment to door 170 without rails, slots, notches, pins, hems, etc.

[0046] The embodiments provided herein can enable the accommodation and routing of at least 288 fibers per RU, which can, for example, facilitate VSFF connectivity. Additionally or alternatively, the embodiments provided herein can enable the management, routing, and load-bearing of cables with multiple RUs (e.g., 1 RU, 2 RU, 4 RU, 6 RU, etc.), as described in the Fig. 6A-6B shown as examples.

[0047] The embodiments provided herein can facilitate cable management on a front cable management tray, improve the speed and ease of installation and assembly of Panel 100, Bodies 110, and routing, and permit installation on standard (e.g., 19-inch) and non-standard telecommunications racks and frames. The embodiments provided herein can eliminate the need for additional rack RU space, allow for depth adjustment of the front door and cable management tray, and accommodate at least 288 fibers per RU.
