Abstract:     A fiber optical control system for use in an optical switch generally includes, in one embodiment, a fiber assembly (86), a signal separator (88), a sensor unit (90), a lens assembly (92), stationary mirror (94), targeting RED (96), moveable mirror assembly (98) with mounted alignment REDs (100), window (102) and a processor (104). The separator (88) separates the control signals from the communication signals so that the control signals are received by the sensor unit (90) and the communication signals are received by fiber (106). The control signals received by the sensor unit (90) provide target identification and alignment information for connecting target fibers. In particular, the targeting RED (96), or in alternative embodiments the alignment REDs, associated with a signal fiber can be pulsed or otherwise operated to convey target identification information, thereby avoiding the need for a long series of column and row signaling for targeting. The moveable mirror assembly (98) includes moveable mirror surfaces (132) with related control elements and REDs (100) mounted on a housing (134). The assembly (98) is used to actuate both targeting and alignment adjustments. The mirror surfaces (132) move in response to commands from processor (104) to allow for adjustment of the optical path of the communication and control signals received through window (102) in two dimensions relative to the fiber (106) and sensor unit (90).

First Claim:
Show all 22 claims		 What is claimed is:     1. An apparatus for use in controlling a fiber optic switch to establish a connection with a target optical fiber from among a plurality of optical fibers, said apparatus comprising:
  • a plurality of control signal source systems, associated with said plurality of optical fibers, for transmitting control signals for use in controlling switching as between said plurality of optical fibers; and
  • targeting means for operating one of said source systems associated with a corresponding one of said plurality of said fibers so as to transmit a target identification code signal, wherein said code signal transmitted by said one source system associated with said one fiber includes identification information sufficient to identify said target fiber.
