Abstract

Disclosed is a module for connecting optical fibers in a lightwave cross-connect distribution system. The module includes a curved channel for receiving an optical fiber cable. The channel is open along a major surface of the module housing to permit the cable to flex out of the channel while the module is inserted or removed from a distribution shelf.

Claims

1. A device comprising:

a housing including an interior and a curved outer surface;

a channel formed within a portion of the curved surface, said channel being open along said curved surface and including a port communicating with the interior of the housing;

an optical fiber cable secured to said housing so that the cable enters the interior at said port and a portion of the cable is positioned within the channel while the device is installed within a shelf and said portion is free to flex outside the channel during the device installation in and removal from the shelf; and

an array of optical fiber connectors mounted at another surface of said housing.

2. The device according to claim 1 wherein the cable includes a sheathing which has a diameter in the range 0.15 to 0.36 inches.

3. The device according to claim 1 wherein the cable is secured to the housing by a clamp located near said port.

4. The device according to claim 1 further comprising a movable member at a portion of the channel remote from the port, which member retains the cable within the channel and is moved out of the channel during device installation and removal to permit flexing of the cable outside the channel.

5. The device according to claim 1 wherein the radius of curvature of the curved surface is at least 3 inches.

6. The device according to claim 2 wherein the cable includes at least one fiber and reinforcement member within the sheathing, and the sheathing and reinforcement member are removed within the interior of the housing to expose the fiber.

7. The device according to claim 1 wherein the channel is formed in a plane which is offset from the plane including the connectors.
