Abstract

A cable routing guide attached to a fiber optic apparatus, such as a module positioned on a fiber optic equipment tray is disclosed. The cable routing guide is adapted to receive a length of at least one fiber optic cable intended to be connected to a cable connection point, such as a fiber optic adapter disposed on the module. The cable routing guide allows the at least one fiber optic cable to move in response to the fiber optic equipment tray or the module moving between a first position and a second position in a manner such that the length of the at least one fiber optic cable from the cable routing guide to the fiber optic adapter remains substantially unchanged. Moreover, the at least one fiber optic cable that is received by the cable routing guide may be retained and maintained by the cable routing guide without being tensed or stressed. In this manner, the at least one fiber optic cable that is routed to and through the fiber optic apparatus may not be affected by the movement of the module frame, the module, and/or the adapter between the first and second positions.

Claims

1. A cable routing guide, comprising:

an arm adapted to be attached to a structure, wherein the structure includes at least one cable connection point movable with respect to the structure between a first and second position; and

a guide piece attached to the arm, wherein the guide piece is adapted to receive a length of at least one cable intended to be connected to the at least one cable connection point, and wherein the guide piece is oriented to the structure such that the guide piece allows the at least one cable to move in response to the cable connection point moving between the first position and the second position in a manner that the length of the at least one cable from the guide piece to the cable connection point remains substantially unchanged.

2. The cable routing guide of claim 1, wherein the guide piece is displaced from the longitudinal axis of the cable connection point a certain distance.

3. The cable routing guide of claim 1, wherein the guide piece is displaced from a transverse axis of the cable connection point a certain distance.

4. The cable routing guide of claim 1, wherein the guide piece is angularly displaced from a longitudinal axis of the cable connection point.

5. The cable routing guide of claim 4, wherein the guide piece is angularly displaced from a longitudinal axis of the cable connection point between 0 and 90 degrees.

6. The cable routing guide of claim 1, wherein the guide piece is located between the first and second positions of the cable connection point.

7. The cable routing guide of claim 1, wherein the cable is a fiber optic cable having at least one optical fiber with a connector attached thereto.

8. The cable routing guide of claim 7, wherein the cable connection point comprises a fiber optic adapter configured to receive the connector.

9. The cable routing guide of claim 1, wherein the cable connection point comprises a fiber optic module with a fiber optic adapter disposed on the fiber optic module, and wherein the fiber optic module moves between the first position and the second position.

14. The fiber optic apparatus of claim 1, further comprising a jumper guide attached positioned between the cable routing guide and the at least one adapter, and wherein the jumper guide receives a portion of the length of the fiber optic cable from the cable routing guide.

15. The fiber optic apparatus of claim 14, wherein the jumper guide is adapted to align the portion of the length of the fiber optic cable with the at least one adapter.

16. The fiber optic apparatus of claim 15, wherein the cable routing guide is located between the first and second positions of the module.

10. A fiber optic apparatus, comprising:

a fiber optic equipment tray;

at least one module movably engaged with the fiber optic equipment tray, wherein the module moves between a first and a second position;

at least one adapter disposed on the module, the adapter configured to receive a connectorized end of a fiber optic cable;

a cable routing guide, wherein the cable routing guide is adapted to receive a length of the fiber optic cable intended to be connected to the at least one adapter, and wherein the cable routing guide allows the fiber optic cable to move in response to the module moving between the first position and the second position in a manner that the length of the fiber optic cable between the cable routing guide and the module remains substantially unchanged.

11. The fiber optic apparatus of claim 10, wherein the cable routing guide is displaced from a longitudinal axis of the at least one adapter a certain distance.

12. The fiber optic apparatus of claim 10, wherein the cable routing guide is displaced from a transverse axis of the at least one adapter a certain distance.

13. The fiber optic apparatus of claim 10, wherein the cable routing guide is angularly displaced from a longitudinal axis of the at least one adapter.

17. A fiber optic apparatus, comprising:

a movable fiber optic equipment tray;

a fiber optic module positioned on the fiber optic equipment tray, wherein the fiber optic module has a fiber optic adapter disposed therein; and

a cable routing guide adapted to receive a length of at least one fiber optic cable intended to be connected to the fiber optic adapter;

wherein the cable routing guide allows the at least one fiber optic cable to move in response to the fiber optic equipment tray moving between a first position and a second position in a manner wherein the at least one fiber optic cable that is received by the cable routing guide may be retained and maintained by the cable routing guide without being substantially tensed or stressed.

18. The fiber optic apparatus of claim 17, wherein the length of the at least one fiber optic cable from the cable routing guide to the adapter remains substantially unchanged.

19. The fiber optic apparatus of claim 17, wherein the at least one fiber optic cable received by the cable routing guide is routed through the fiber optic apparatus to the cable routing guide, and wherein the at least one fiber optic cable is not substantially affected by the movement of the fiber optic equipment tray, the module, and/or the adapter between the first and second positions as the at least one fiber optic cable is routed to the cable routing guide.
