Abstract

The present invention relates to the management of cables extending to and from fiber termination blocks with sliding angled fiber adaptor modules within a fiber distribution frame.

Claims

1. A signal transmission cable management system comprising:

a fixture; and

a plurality of modules mounted on the fixture with each of the modules movably mounted on the fixture for movement along a line of travel, each one of the modules including a plurality of adaptors for holding a fiber optic connector, each adaptor having opposite ends for coupling to a fiber optic cable connector, each one of the adaptors movable with the one of the modules along the line of travel, the plurality of adaptors linearly disposed along the line of travel for each of the modules, each adaptor defining a longitudinal connector axis, the connector axes positioned parallel to one another, the line of travel of each module positioned at a non-perpendicular angle to the connector axes.

2. As system according to claim 1 wherein each of the plurality of adaptors couples first and second SC fiber optic cable connectors.

3. A system according to claim 1 wherein each of the plurality of adaptors couples first and second FC fiber optic cable connectors.

4. A system according to claim 1 wherein the modules each have a longitudinal axis, the modules mounted on the fixture in side-by-side relation with the longitudinal axes generally parallel to the line of travel, the plurality of adaptors linearly disposed along the longitudinal axis.

5. A system according to claim 1 wherein the fixture defines a plurality of channels, each of the modules being disposed within a respective channel, and further comprising cooperating guides on each of the modules and within the channels accommodating movement of each of the modules along the line of travel.

6. A system according to claim 5 further including a plurality of spaced-apart walls, opposing pairs of the walls defining the plurality of channels, each of the modules being disposed within a respective channel, and wherein the cooperating guides are on each of the walls for attaching the modules to the walls.

7. A system according to claim 1, further comprising a releasable lock for locking each module to the fixture in a first position, each of the locks being releasable to allow movement of each of the modules to a second position along the line of travel.

19. A system according to claim 1, wherein the adaptors are staggered along the line of travel.

8. In a signal transmission cable management system having a fixture including a plurality of spaced apart walls defining a plurality of parallel spaced apart cavities, the walls including first and second parallel and opposing recesses;

a module for mounting in the cavities, the module comprising;

a body sized to be slideably received within the cavity for movement along a line of travel, the body having first and second parallel rails, the rails sized to be slideably received within the recesses; and

the body including a plurality of adaptors for connecting a plurality of fiber optic cables to the body, the plurality of adaptors linearly aligned along the line of travel, each adaptor defining a longitudinal connector axis, the connector axes positioned parallel to one another, the line of travel of each module positioned at a non-perpendicular angle to the connector axes.

9. A module according to claim 8 wherein each of the plurality of adaptors couples first and second SC fiber optic cable connectors.

10. A module according to claim 8 wherein each of the plurality of adaptors couples first and second FC fiber optic cable connectors.

11. A module according to claim 8 comprising a latch for securing the body to the fixture in a first position.

20. A module according to claim 8, wherein the adaptors are staggered along the line of travel.

12. A fiber optic connector assembly comprising:

a fixture having a first end and a second end;

a plurality of signal transmission modules mounted on the fixture between the first and second ends, with each of the modules movably mounted on the fixture for movement along a line of travel, each one of the modules including a plurality of adaptors for holding a fiber optic connector, each one of the adaptors movable with one of the modules along the line of travel, each adaptor defining a longitudinal axis, the longitudinal axes extending parallel to one another between the front end and the back end of the fixture, the line of travel of each module positioned at a non-perpendicular angle to the longitudinal axes;

a cable fanning device positioned at the first end, the cable fanning device including a series of spaced cable guides, each cable guide having a linear body extending transversely to the longitudinal axes, the linear body having a curved outer surface, the cable guides positioned such that each of the cables connected to a first side of the modules extends from the adaptors in the modules to the curved body of one of the cable guides and passes into a cable channel on the first end of the fixture;

wherein the line of travel of each module is angled toward the cable fanning device.

13. The fiber optic connector assembly of claim 12, wherein a first and a second group of signal transmission modules are movably mounted adjacent to one another on the fixture and are configured so that the line of travel of the first group of signal transmission modules is positioned in a mirror image to the line of travel of the other group of signal transmission modules, and further that the first group and the second group of signal transmission modules are configured to move in opposite angled directions to the cable fanning device.

21. The fiber optic assembly of claim 12, wherein the adaptors are staggered along the line of travel.

14. An optical fiber distribution frame comprising:

a support structure defining a vertical support;

a plurality of fiber optic connector assemblies mounted on the vertical support in a single row, each fiber optic assembly including;

a fixture having a first end and a second end;

a plurality of signal transmission modules mounted on the fixture with each of the modules movably mounted on the fixture for movement along a line of travel, each one of the modules including a plurality of adaptors for holding a fiber optic connector, each one of the adaptors movable with one of the modules along the line of travel, each adaptor defining a longitudinal axis, the longitudinal axes extending parallel to one another between the front end and the back end of the fixture, the line of travel of each module positioned at a non-perpendicular angle to the longitudinal axes;

a cable fanning device positioned adjacent to the first end, the cable fanning device including a series of spaced arcuate cable guides, each arcuate cable guide having a linear body extending transversely to the longitudinal axes, the linear body having a curved outer surface, the arcuate cable guides positioned such that each of the cables connected to a first side of the modules extends from the adaptors in the modules to the curved body of one of the arcuate cable guides and passes into a cable channel on the first end of the fixture;

wherein the line of travel of each module is angled toward the cable fanning device.

15.
