Abstract

A cable mount for fixing a strength member of a fiber optic cable to a fixture includes a front end, a rear end, and a longitudinal channel therebetween, the channel defined by upper and lower transverse walls and a vertical divider wall. The channel receives a portion of the cable. A strength member pocket receives the strength member of the cable, the pocket located on an opposite side of the divider wall from the longitudinal channel, the pocket communicating with the longitudinal channel through an opening on the divider wall. A strength member clamp fixes the strength member of the cable against axial pull. Cable management structures in the form of spools define at least one notch that communicates with the longitudinal channel for guiding optical fibers extending from a jacket either upwardly or downwardly therethrough. The cable mount also allows routing of the optical fibers through the longitudinal channel all the way from the rear end to the front end.

First claim

What is claimed is:

1. A cable mount configured for fixing a strength member of a fiber optic cable to a fixture, the cable mount comprising:
a front end, a rear end, and a longitudinal channel extending between the front end and the rear end for receiving a portion of the fiber optic cable, the cable mount further comprising a divider wall;
a strength member pocket for receiving the strength member of the fiber optic cable, the strength member pocket located on an opposite side of the divider wall from the longitudinal channel, the strength member pocket communicating with the longitudinal channel through an opening provided on the divider wall; and
a strength member clamp configured to fix the strength member of the fiber optic cable against axial pull relative to the cable mount.

2. A cable mount according to claim 1 , further comprising a mounting structure for mounting the cable mount to the fixture.

3. A cable mount according to claim 2 , wherein the mounting structure is configured to define a slidable interlock with the fixture.

4. A cable mount according to claim 3 , wherein the slidable interlock is defined by dovetail structures.

5. A cable mount according to claim 3 , wherein the strength member clamp is defined in an inset portion of the cable mount so as to not interfere with the slidable mounting of the cable mount to the fixture.

6. A cable mount according to claim 1 , wherein the strength member clamp is defined by a base of the cable mount and a fixation plate that is clamped to the base with at least one clamp fastener.

7. A cable mount according to claim 1 , further comprising at least one cable management structure in the form of a spool for managing and guiding optical fibers extending from a jacket of the fiber optic cable from the longitudinal channel.

8. A cable mount according to claim 7 , wherein the spool is removably mounted to the cable mount base portion via a snap-fit interlock.

9. A cable mount according to claim 1 , wherein the longitudinal channel defines a jacket channel adjacent the rear end of the cable mount and a fiber channel adjacent the front end of the cable mount, the jacket channel configured to receive the jacket of the fiber optic cable and the fiber channel configured to receive the optical fibers extending from the jacket of the fiber optic cable.

10. A method of fixing a strength member of a fiber optic cable to a fixture, the method comprising:
inserting a front end of the fiber optic cable through a longitudinal channel of a cable mount that is on the fixture;
inserting the strength member of the fiber optic cable through an opening on a divider wall into a pocket located on an opposite side of the divider wall from the longitudinal channel while keeping optical fibers extending from a jacket of the fiber optic cable on the side of the longitudinal channel; and
clamping the strength member of the fiber optic cable against axial pull relative to the cable mount.

11. The method of claim 10 , wherein the fixture is a fiber optic distribution element defined by a chassis and a tray slidable with respect to the chassis.

12. The method of claim 10 , wherein the cable mount is removably mounted to the fixture.

13. The method of claim 12 , wherein the cable mount is slidably mounted to the fixture.

14. The method of claim 13 , wherein the cable mount is slidably mounted to the fixture via dovetail shaped interlock features.

15. The method of claim 10 , wherein the strength member is clamped between a base defined by the cable mount and a fixation plate that is fastened to the base with at least one clamp fastener.

16. The method of claim 10 , further comprising guiding the optical fibers extending from the jacket of the fiber optic cable around a cable management structure in the form of a spool of the cable mount.
