Abstract

See full text

An optical add/drop multiplexer incorporates an integrated receiver module and an integrated transmitter which are interfaced to an intervening electrical network to provide an add/drop/pass-through functionality. The receiver module incorporates a wavelength demultiplexer which is in turn combined with optical/electrical converters PIN photodiodes, and amplifiers on a per wavelength basis to output a plurality of parallel electrical signals in response to a common optical input. The transmitter module combines an integrated plurality of drive circuits and lasers for converting a plurality of parallel input electrical signals to a plurality of optical signals, on a per wavelength basis, which in turn are coupled via an optical wavelength multiplexer to a common output optical fiber. The interconnected electrical network, ring mesh or tree, can provide a reconfigurable electrical add/drop interface to other portions of the network.
