Abstract
Depletion in power due to Stimulated Raman Scattering (SRS) impairs Wavelength Division Multiplexed (WDM) system performance. This is countered usually by placing optical amplifiers to maintain required Bit Error Rate (BER) performance. Also, impact of crosstalk in N x N WDM systems causes high noise power. In this paper we propose the use of block codes for forward error correction as a possible method for improving the performance of WDM systems in the presence of SRS and crosstalk. Our results show that with 200 users and with error control coding, the detector can effectively receive the required power and attain the desired BER performance in SRS limited WDM systems. Our results also show that the multiplexer crosstalk effectively comes down to -44 dB from -34 dB. © 2006 ISRAMT. All Rights Reserved.
