The all-optical code translation Scheme for an OCDMA optical code division multiple access system based on nonlinear optical loop mirror

提出了一种利用非线性光纤环镜(NOLM)实现二维全光码字转换方法,设计了基于NOLM的码字转换方案,并进行了系统性能仿真分析。研究结果表明:该方法能够成功实现系统的数据传输;采用这种码字转换方法,系统误码率性能远远高于没有进行码字转换的系统性能。

The code translation method for the wavelength-time optical code division multiple access （OCDMA） system based on nonlinear optical loop mirror （NOLM） is proposed. The all optical code converter scheme is designed. Moreover,the biterror-rate （BER） performance of the proposed converter scheme is analyzed and simulated. The simulation results show that the OCDMA system using the code converters has better BER performance than that without code converters. The data can be successfully transmitted.
