Abstract :
We propose an optical subcarrier multiplexing system that uses optical sampling multiplexer to suppress optical beat interference in an up-link. This type of interference can be dramatically suppressed without distorting the signal by replacing the passive coupler-based multiplexer in a conventional subcarrier multiplexing system with our proposed time sampling multiplexer. We discuss from theoretical viewpoints the effect of our proposed multiplexer on the BER, CNR and CIR performance
