✦ Synopsis

NRZ, duobinary, RZ, CS-RZ and SSB-RZ modulation formats are evaluated numerically at a bit rate of 40 Gbit/s for single-channel and WDM systems using long fibre spans of 80 km SMF + DCF or SMF + IDF Â 2. For the singlechannel system, conventional RZ with narrow pulses is found to be optimum, whereas CS-RZ performs the best for the WDM system. Using SMF + IDFÂ2 fibre span results in significant longer transmission distance due to reduced span loss.
