Abstract
A system to facilitate alignment of an optical connector to respective optical channels of one or more optical arrays. Optical planar arrays having multiple optical emitters and multiple optical detectors of a multi-channel optical link are aligned by employing supporting circuitry and software that controls the optical devices, enabling all receivers, turning on the transmitters sequentially, and recording the optimal transmitter/receiver pairs. Another feature of the invention is the aspect of redundancy, wherein the system establishes a record of spare emitters and spare detectors that are used when the selected transmitter receiver pair degrades or fails. The techniques of the present invention also provide a unique multiplexer/demultiplexer arrangement for a single wavelength channel of emitters and detectors.
