光码分多址(OCDMA)的实现及应用

摘要

OCDMA technology is the next generation optical technology that can used in optical channel multiplexing,multiple access optical networks,secure transmission of optical signals.The fundamental of optical code division multiple access (OCDMA) is introduced,followed by analysis code word sequence,encoder/de coder,narrow pulse receiver and other key technologies of OCDMA system.Finally,the application includedhidden communication based on OCDMA,OCDMA over PON are discussed.%光码分多址(0CDMA)技术是下一代的光通信技术,可广泛用于光信道复用、光网络多址接入和光信号安全传输等.概述了实现0CDMA系统的光码码字序列、光编解码器、超短脉冲光源和接收机等关键技术,最后介绍了基于0CDMA技术的0CDMA-P0N、隐匿通信等应用.
