.Improvement of normalized throughput in WDM+OCDMA system using optical hard-limiters[J].Optoelectronics Letters,2006,2(1):55-57 Improvement of normalized throughput in WDM+OCDMA system using optical hard-limiters JI Jian-hua XU Ming YANG Shu-wen ZHANG Zhi-peng Advanced Technology Research Center of Shenzhen University, Shenzhen 518060, China Abstract:       A scheme of WDM+OCDMA system employing optical hard-limiter (OHL) is proposed, and its performance of normalized throughput is analyzed. The upper bound of the normalized throughput is obtained when all the simultaneous users are equally allocated to different wavelength channels. The lower bound of the normalized throughput is obtained when all the simultaneous users are firstly allocated to the same wavelength channels. Compared with the performance of WDM+OCDMA system without OHL, both the upper bound and lower bound of the normalized throughput in WDM+OCDMA system with OHL can be improved.
