Reed Solomon Code and Semiconductor Optical Preamplifier in OOK Communication System: A Comparative Study

In this paper, performance of OOK communication system with Reed-Solomon (R-S) (31,27,2) code and semiconductor optical amplifier (SOA) has been analyzed. In the analysis, effect of intersymbol interference (ISI) due to Gaussian filter in the receiver has been considered. It is observed that the use of SOA is much more advantageous than coding scheme. For a BER of 10 -9 , the coding gain is 1.7 dB, while the gain due to optical preamplifier is 21.2 dB.
