Abstract: In this paper, performance of RZ (Return to Zero On-Off Keying) modulation was investigated in WDM (Wavelength Division Multiplexing) based Single Mode Fibre (SMF). The simulation was done by the Industrial Software OptSIM for 40GBit/s. Three different length of Single Mode Fibre (90 km, 180 km, 270 km) were chosen for 4 and 16 channel WDM and the length of Dispersion Compensated Fibre was fixed accordingly. For each number of channel, fibre span was varied in accordance with the lengths mentioned above. The BER (Bit Error Rate) was estimated for the best as well as the for the worst channel scenario. Analysing „4 Channel WDM‟ simulation, rapid increase of BER was observed for “RZ-OOK” as it increased from 10-9 to 10-8. “RZ-OOK” continued to show poor result as its BER was ranged from 10-6 to 10-4 for 16 channel. Therefore, it was concluded that for long haul transmission in SMF, RZ showed moderate performance both in 8 and 16 Channel WDM
