Abstract

Apparatus and methods for controlling the movement of optical fiber cables wherein said apparatus includes a cam plate which defines a pair of cam tracks. A pair of cam followers is also provided such that the cam plate moves with respect to the cam followers from a first location to a second location, and in such a manner that both the extent of the movement and the direction of movement of the structure and an attached optical fiber are controlled.

Claims

1. Apparatus for controlling the movement of cables attached to a panel comprising:

a support structure associated with said cables;

an attachment member selectively supported by said support structure at a first location, and movable between said first location and a second location, at least one of said cables secured to said attachment member;

a cam plate secured to said attachment member, said cam plate defining a pair of cam tracks, each having a selected path shape and a selected length of path; and

a pair of cam followers supported in a fixed position with respect to said support structure, said cam followers being received by said cam tracks such that the direction of movement and the amount of movement of said attachment member and said at least one cable is controlled by movement of said cam followers in said cam tracks.

2. The apparatus of claim 1 wherein said at least one cable comprises more than one cable.

3. The apparatus of claim 1 wherein said at least one cable is an optical transmission fiber.

4. The apparatus of claim 1 and further comprising at least one securing member and wherein said attachment member is secured to said support structure by said at least one securing member.

5. The apparatus of claim 1 and further comprising an optical connector and wherein said at least one cable is secured to said attachment member by said optical connector.

6. The apparatus of claim 1 wherein said attachment member includes a bulkhead optical connector having an inside portion and an outside portion and said at least one cable is attached to said inside portion of said optical connector.

7. The apparatus of claim 1 wherein said cam tracks allow limited movement in a first direction and then allows movement in at least one second direction.

8. The apparatus of claim 7 wherein said cam tracks allow rotation of said attachment member upon completion of said first limited movement to allow said limited movement in said second direction.
