• This paper investigates the effect of crosstalk in multichannel coherent optical ASK systems. A closed-form signal-to-noise ratio (SNR) expression as a function of number of channels, channel separation, laser phase noise, intermediate frequency (IF) filter bandwidth expansion factor (α), system bit rate (R_b= 1/T), and additive shot noise is presented. When the desired channel is between two channels in the electrical domain, the minimum permissible electrical domain channel spacing for a 1 dB sensitivity penalty due to crosstalk is found to be 4.85R_b when α is optimum ; and 8R_b when α=5 for ΔυT=0.30 at BER = 10^lt-9gt. A fairly good agreement is found between the results of this work and those of a previous study.
