In a binary asymmetric channel (BAC) it may be necessary to correct only those errors that result from incorrect transmission of one of the two code elements. In optical fibre multichannel systems, the optical amplifiers are critical components and amplified spontaneous emission (ASE) noise in the optical amplifiers is the major source of noise in it. In this study, performance of single as well as concatenated error correcting codes in such systems in presence of stimulated Raman scattering and ASE noises (ASE, ASE-Signal beat and ASE-ASE beat) with asymmetric channel statistics with binary pulse position (BPPM) modulation scheme is reported. The error probability performances have been evaluated and compared between un-coded OOK, coded BAC with OOK and coded BPPM systems. The coded BPPM is found to be more efficient and has a better error rate than others.
