Abstract

A fiber optic telecommunications device includes a frame defining a right vertical support and a left vertical support. A chassis is mounted to the right and left vertical supports, wherein the chassis is configured to pivot about a pivot axis that is defined by one of the right and left vertical supports. A plurality of modules are mounted on the chassis, each of the modules slidable on the chassis along a direction extending between the right and left vertical supports, wherein the chassis is configured to pivot about a plane parallel to the sliding direction of the modules, each module defining fiber optic connection locations.

Claims

1. A fiber optic chassis comprising:

a right rack mount portion and a left rack mount portion and at least one slide extending between the right and left rack mount portions, one of the right rack mount portion and the left rack mount portion defining at least a part of a hinge structure for pivotally mounting the fiber optic chassis to a telecommunications fixture;

a plurality of modules mounted on the chassis along a horizontal stack extending between the right and left rack mount portions, each of the modules slidable on the slide along a direction extending between the right and left rack mount portions, wherein each module includes at least one slide hole that is completely surrounded around its periphery, the at least one slide hole extending through the module and defining open ends that are aligned along the direction extending between the right and left rack mount portions, the at least one slide hole configured to receive the slide of the chassis for allowing the module to be slidable between the right and left rack mount portions, each module configured to receive fiber optic equipment defining fiber optic connection locations.

2. A fiber optic chassis according to claim 1, wherein each of the modules is populated with the fiber optic equipment that defines the fiber optic connection locations.

3. A fiber optic chassis according to claim 2, wherein the fiber optic connection locations are defined by fiber optic adapters.

4. A fiber optic chassis according to claim 3, wherein the fiber optic adapters are LC-format adapters.

5. A fiber optic chassis according to claim 2, wherein the fiber optic equipment are fiber optic cassettes removably mounted to the modules, the fiber optic cassettes defining fiber optic adapters at a first end, a cable extending from an opposite second end, and fibers extending within the cassette from the cable to the fiber optic adapters.

6. A fiber optic chassis according to claim 1, wherein each module defines a cable management structure for guiding cables extending to and from the fiber optic connection locations.

7. A fiber optic chassis according to claim 6, wherein the cable management structure defines a split-ring configuration.

8. A fiber optic chassis according to claim 1, wherein one of the right rack mount portion and the left rack mount portion defines a latch for locking the chassis in a closed position when the chassis is not pivoted with respect to the telecommunications fixture.

9. A fiber optic chassis according to claim 1, further comprising a cable management module slidable along the same direction as the modules, the cable management module including a cable management structure in the form of a split-ring configured to manage cables extending to and from the modules.
