Abstract

In a highly asymmetric channel it may be necessary to correct only the errors result from incorrect transmission. A Long haul incoherent optical multichannel communication systems with EDFAs employing N × N Wavelength Division Multiplexing (WDM) in presence of Stimulated Raman Scattering (SRS) and other receiver noises, including channel beat noise, is analyzed. Error control coding techniques such as Block, RS, Golay and rate 1/2 convolution codes are employed to counter system degradation due to these limiting factors. Without coding BER of 10-9 can be achieved at the maximum of 70 channels while, with coding, it can be achieved beyond 100 channels. In other words the power penalty for 100 channels reduces from 2.6dB to 0.7078dB with coding in presence of both SRS and channel beat noise.
