Abstract :
Long-term BER measurements (10 h) of a single-channel 160 Gbit/s transmission over 4/spl times/80 km high-dispersion fibre are reported, using a single polarisation signal, RZ-DPSK coding and EDFA amplification solely. Pulse source, demultiplexing optical gate, clock recovery and the balanced detector are based on semiconductor components. Completely error-free transmission was observed for more than 5 h without using FEC.
