Abstract
Long haul incoherent optical multichannel communication systems employing N * N Wavelength Division Multiplexing (WDM) in presence of Stimulated Raman Scattering (SRS) and other receiver noises including channel and Amplified Spontaneous Emission (ASE) beat noises is analyzed. Concatenated error control coding techniques are employed to counter system degradation due to these limiting factors. It is shown that the Bit Error Rate (BER) of the order of 10-9 can be achieved for large values of N (=270) at link length of 200km without crossing SRS threshold of 1dB. Also power penalty due to multiplexer crosstalk effectively comes down from 5.5dB to 0.14dB for a 64 channel WDM system. © 2007 ISRAMT. All Rights Reserved.
