Abstract
In this paper the authors report on experiments in a 107 Gbit/s RZ-DPSK system. The receiver was based on pure electrical time-division multiplexing. It comprised a high-bandwidth balanced photodetector (u2t) and a CDR-chip ('Clock & Data Recovery', Micram) for simultaneous demultiplexing and recovery of the clock signal. The transmitter used optical time division multiplexing (OTDM) techniques. This allowed to generate a high quality 107 Gbit/s RZ-DPSK signal, which was not limited by the bandwidth of the modulator or the electrical driver amplifiers. Measurements of eye diagrams and bit-error rates for 53.5 and 107 Gbit/s are presented and com-pared. The transmission of 107 Gbit/s DPSK signals over 320 km dispersion managed fiber is demonstrated
