摘要: 提出了一种新的基于光码分多址的WDM-PON系统(OCDMA+WDM PON),分析了系统的性能。仿真结果表明,将OCDMA和WDM相结合用于无源光网络,在每个WDM信道中嵌入一组OCDMA用户,有利于系统扩容,网络性能也能得到保证。

Abstract: The structure of OCDMA over WDM-PON system was proposed, the performance of this system was analyzed. The simulation results show that when OCDMA and WDM were combined in passive optical network by inserting a group of OCDMA subscribers in each WDM channel, the number of subscribers can satisfy the demand easily, and the performance of the system can be guaranteed.

Key words: optical code division multiple access(OCDMA), wavelength division multiplexing(WDM), passive optical network(PON)
