Abstract

A rack or cabinet system, including: a cabinet adapted to receive a circuit pack; a trough assembly movably coupled to the cabinet, where the trough assembly is adapted to receive a plurality of client fibers from a faceplate of the circuit pack; and a hinge assembly coupled to the cabinet and adapted to pivot the trough assembly away from/towards a front portion of the cabinet and the circuit pack. The trough assembly and the hinge assembly are collectively adapted to pivot the trough assembly away from the front portion of the cabinet and the circuit pack to move the plurality of client fibers such that a plurality of fabric cables coupled to front-side portions of the circuit pack behind the plurality of client fibers can be accessed by a user.

Claims (31)

1 . A rack/cabinet system, comprising:

a cabinet adapted to receive a circuit pack;

a trough assembly movably coupled to the cabinet, wherein the trough assembly is adapted to receive a plurality of fibers or cables from a faceplate of the circuit pack; and

an assembly coupled to the cabinet and adapted to move the trough assembly away from/towards an open portion of the cabinet and the circuit pack;

wherein the trough assembly is movable or rotatable from a position corresponding to an internal portion of the circuit pack in an open configuration exposing fibers or cables coupled to a side portion of the circuit pack to another position corresponding to the side portion of the circuit pack in a closed configuration in which an associated side of the cabinet blocks the fibers or cables coupled to the side portion of the circuit pack.

2 . The system of claim 1 , wherein the trough assembly comprises a trough body adapted to route the plurality of fibers or cables upwards and/or downwards to a top and/or bottom of the cabinet.

3 . The system of claim 2 , wherein the plurality of fibers or cables utilize a degree of slack that is adapted to span a distance between a top and/or bottom portion of the trough body and the top and/or bottom of the cabinet when the trough assembly is moved away from the open portion of the cabinet and the circuit pack.

4 . The system of claim 2 , wherein the trough assembly further comprises a bend limiter disposed at a top and/or bottom portion of the trough body adapted to limit a degree of bending of the plurality of fibers or cables at the top and/or bottom portion of the trough assembly.

5 . The system of claim 2 , wherein the trough assembly further comprises a bracket adapted to couple the trough body to the assembly.

6 . The system of claim 2 , wherein the trough body defines a plurality of slots adapted to receive the plurality of fibers or cables from the faceplate of the circuit pack.

7 . The system of claim 1 , wherein the assembly is a hinge assembly and comprises a fixed arm coupled to the cabinet and a pivoting arm pivotably coupled to the fixed arm.

8 . The system of claim 7 , wherein the hinge assembly further comprises a stop feature that limits a degree of pivoting of the pivoting arm relative to the fixed arm.

9 . The system of claim 1 , wherein, in the open configuration, the trough assembly is away from the open portion of the cabinet and the circuit pack, and is pivoted to the associated side of the cabinet and the open portion of the cabinet and the circuit pack in the closed configuration.

10 . A trough assembly for a rack/cabinet system, the trough assembly comprising:

a trough body adapted to be movably coupled to a cabinet adapted to receive a circuit pack, wherein the trough body is adapted to receive a plurality of fibers or cables from a faceplate of the circuit pack; and

an assembly coupling the trough body to the cabinet and adapted to move the trough body away from/towards an open portion of the cabinet and the circuit pack;

wherein the trough assembly is movable or rotatable from a position corresponding to an internal portion of the circuit pack in an open configuration exposing fibers or cables coupled to a side portion of the circuit pack to another position corresponding to the side portion of the circuit pack in a closed configuration in which an associated side of the cabinet blocks the fibers or cables coupled to the side portion of the circuit pack.

11 . The trough assembly of claim 10 , wherein the trough body is adapted to route the plurality of fibers or cables upwards and/or downwards to a top and/or bottom of the cabinet.

12 . The trough assembly of claim 11 , wherein the plurality of fibers or cables utilize a degree of slack that is adapted to span a distance between a top and/or bottom portion of the trough body and the top and/or bottom of the cabinet when the trough body is moved away from the open portion of the cabinet and the circuit pack.

13 . The trough assembly of claim 11 , wherein the trough assembly further comprises a bend limiter disposed at a top and/or bottom portion of the trough body adapted to limit a degree of bending of the plurality of fibers or cables at the top and/or bottom portion of the trough body.

14 . The trough assembly of claim 11 , wherein the trough assembly further comprises a bracket adapted to couple the trough body to the assembly.

15 . The trough assembly of claim 11 , wherein the trough body defines a plurality of slots adapted to receive the plurality of fibers or cables from the faceplate of the circuit pack.

16 . The trough assembly of claim 10 , wherein the assembly is a hinge assembly and comprises a fixed arm adapted to be coupled to the cabinet and a pivoting arm pivotably coupled to the fixed arm.

17 . The trough assembly of claim 16 , wherein the hinge assembly further comprises a stop feature that limits a degree of pivoting of the pivoting arm relative to the fixed arm.

18 . The trough assembly of claim 10 , wherein, in the open configuration, the trough body is away from the open portion of the cabinet and the circuit pack, and is pivoted to the associated side of the cabinet and the open portion of the cabinet and the circuit pack in the closed configuration.

19 . A method for providing access to a plurality of blocked fibers or cables in a rack/cabinet system, the method comprising:

providing a cabinet adapted to receive a circuit pack;

providing a trough assembly movably coupled to the cabinet, wherein the trough assembly is adapted to receive a plurality of fibers or cables from a faceplate of the circuit pack; and

providing an assembly coupled to the cabinet and adapted to move the trough assembly away from/towards an open portion of the cabinet and the circuit pack;

wherein the trough assembly is movable or rotatable from a position corresponding to an internal portion of the circuit pack in an open configuration exposing fibers or cables coupled to a side portion of the circuit pack to another position corresponding to the side portion of the circuit pack in a closed configuration in which an associated side of the cabinet blocks the fibers or cables coupled to the side portion of the circuit pack.

20 . The method of claim 19 , wherein, in the open configuration, the trough assembly is away from the open portion of the cabinet and the circuit pack, and is pivoted to the associated side of the cabinet and the open portion of the cabinet and the circuit pack in the closed configuration.
