Abstract

A optical transceiver that employs matched pairs of photonic components, including laser diodes, photodiodes and filters, and differential electrical compensation with common mode rejection to achieve a high effective level of optical and electrical isolation between signals at the transmitter waveband and signals at the receiver waveband. A novel configuration of WDM filter also improves isolation and both techniques are extended to the triplexer transceiver. Innovative arrangement of the components and contacts permits the realization of a very compact packaged transceiver unit.
