Optical crossbar switch

1. An optical crossbar switch for optically coupling optic fibers comprising:

at least one first fiber and a plurality of second fibers;

a moveable fiber-end carriage coupled to an end of the at least one first fiber and having at least one latching hook and being constrained to move along a predetermined trajectory;

at least one moveable slack-control carriage coupled to the body of the at least one first fiber and constrained to move along a predetermined trajectory;

an array of sockets defined by walls, at least one of which walls of each sockets formed having a latch hole for receiving the latching hook; and

at least one moving device controllable to move the carriages;

wherein to optically couple a first fiber to a second fiber, the at least one moving device moves the fiber-end carriage of at least one of the first and second fibers to a socket and inserts the fiber's fiber end into the socket so that the at least one latching hook latches into the latch hole and secures the carriage to the socket array.

2. An optical crossbar switch according to claim 1 wherein the latching hooks are spring loaded.

3. An optical crossbar switch according to claim 2 wherein the moving device is configured to oppose the spring loading of the at least one latching spring to insert or extract the fiber end into the socket.

4. An optical crossbar switch according to claim 1 wherein the fiber-end carriage comprises an optical reflector.

5. An optical crossbar switch according to claim 1 wherein the moving device comprises a light source and an optical detector and the moving reflects light from the light source from the reflector towards the detector to determine if the moving device is aligned with the fiber-end carriage.

6. An optical crossbar switch according to claim 1 wherein the fiber end carriage comprises at least one bifurcated prong that seats on a wall of a socket when the fiber end is inserted into a socket.
