Abstract

A fiber optic telecommunications system includes a frame and a fiber optic module mounted on the frame via a slide assembly that includes a gear mechanism. The slide assembly is defined by a rack mount portion, a center portion, and a main housing portion. The rack mount portion is stationarily coupled to the frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction. The center portion includes a latch for unlatching the center portion for slidable movement, wherein movement of the center portion with respect to the rack mount portion moves the main housing portion relative to the frame along the sliding direction. The main housing portion is configured for mounting adapters that receive connectorized cables for routing through the frame. The main housing portion includes electrical contacts for relaying an electrical connection established between an adapter mounted on the main housing portion and an optical connector inserted into the adapter, the electrical connection relayed from the electrical contacts of the main housing portion to a frame controller mounted on the frame via printed circuit boards.

First claim

The invention claimed is:

1. A fiber optic telecommunications system comprising:
a telecommunications frame; and
a fiber optic module mounted on the telecommunications frame via a slide assembly that includes a gear mechanism, the slide assembly defined by a rack mount portion, a center portion, and a main housing portion, wherein the rack mount portion is stationarily coupled to the telecommunications frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction;
the center portion including a latch for unlatching the center portion for slidable movement, wherein slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the telecommunications frame along the sliding direction;
wherein the main housing portion is configured for mounting fiber optic adapters that receive connectorized cables to be routed through the telecommunications frame;
wherein the main housing portion includes electrical contacts for relaying an electrical connection established between a fiber optic adapter to be mounted on the main housing portion and a fiber optic connector inserted into the adapter, the electrical connection relayed from the electrical contacts of the main housing portion to a frame controller mounted on the telecommunications frame via printed circuit boards.

2. A fiber optic telecommunications system according to claim 1 , further comprising the fiber optic adapters mounted to the main housing portion of the fiber optic module.

3. A fiber optic telecommunications system according to claim 2 , wherein the fiber optic adapters are LC-format adapters.

4. A fiber optic telecommunications system according to claim 2 , wherein the fiber optic adapters are removably mounted to the main housing portion with a snap-fit interlock.

5. A fiber optic telecommunications system according to claim 1 , wherein the printed circuit boards include a first circuit board positioned on the main housing portion, a second circuit board positioned on the center portion, a third circuit board positioned on the rack mount portion, and a fourth circuit board positioned on the telecommunications frame which is configured to electrically communicate with the third circuit board of the rack mount portion.

6. A fiber optic telecommunications system according to claim 1 , wherein the center portion of the fiber optic module includes a radius limiter for guiding cables between the main housing portion and the telecommunications frame.

7. A fiber optic telecommunications system according to claim 1 , wherein the fiber optic module is removably mounted to the telecommunications frame with a snap-fit interlock.

8. A fiber optic telecommunications system according to claim 1 , wherein the telecommunications frame includes a plurality of the fiber optic modules coupled thereto.

9. A fiber optic telecommunications system according to claim 1 , wherein one of the printed circuit boards includes a flexible printed circuit board in the form of a ribbon cable that is housed by the slide assembly, wherein the ribbon cable is configured to flex as the fiber optic module is slidably moved.

10. A fiber optic telecommunications system according to claim 1 , wherein the slide assembly houses at least one light-emitting diode to identify a particular fiber optic module, the at least one light-emitting diode electrically connected to the printed circuit boards.

11. A fiber optic telecommunications system according to claim 10 , wherein at least a portion of the latch defined by the center portion is made out of transparent material for piping a light emitted by the at least one light-emitting diode.

12. A fiber optic telecommunications system according to claim 1 , wherein the telecommunications frame includes at least one spring-loaded pivot door for allowing and limiting access to the fiber optic module slidably mounted on the telecommunications frame.

13. A fiber optic telecommunications system according to claim 1 , wherein the frame controller is removably mounted to the telecommunications frame.

14. A fiber optic telecommunications system according to claim 1 , wherein the telecommunications frame is mounted on a telecommunications rack, the frame controller electrically communicating with a rack controller of the telecommunications rack.

15. A fiber optic telecommunications system according to claim 14 , wherein the telecommunications rack includes a plurality of the telecommunications frames mounted thereon.
