Abstract
A plurality of differential encoders encodes a plurality of parallel data bit streams. XOR gates interleave the outputs of the differential encoders forming a single high speed differentially encoded bit stream with a data rate that is the sum of the data rate of the parallel data bit streams. The high speed data stream provides a single differentially encoded input to a differential phase shift keying modulator that generates symbols for a high speed optical communication system.
