4-Gbit/s transmission over 103 km of optical fiber using a novel electronic multiplexer/demultiplexer

Abstract

Using a multiplexer and demultiplexer built from discrete GaAs FET's, a directly modulated distributed feedback laser, and a low capacitance avalanche photodiode receiver, we have achieved transmission at 4 Gbit/s over 103 km of single-mode optical fiber at 1.54 μm.
