A 50 to 400 mbit/sec single chip fiber optic receiver circuit

A high speed fiber optic receiver is described which uses a single chip to perform all of the electronic functions. These functions include low noise preamplification, amplification to a logic compatible signal level, and automatic level restoration which maintains the correct receiver decision point over a large range of optical input power. The receiver has operated at bit rates from 50 to 400 Mbit/sec with sensitivities as high as -33 dbm. © 1984 SPIE.
