This paper presents a performance analysis of spectrally phase-encoded optical CDMA over WDM networks. Random access protocol is adopted to assign wavelengths. The discrete time Markov chain model is used to build analytical model of multi-channel random access protocol. The authors measure several performance characteristics, namely, steady-state throughput and average packet delay time. Additionally, the efficiencies of the system, which are based on both the processing gain and the number of WDM wavelengths, are considered. Exponential retransmission is used for solving packet collision problems.
