光码分多址(OCDMA)的实现及应用

Implementation and application of OCDMA

光码分多址(OCDMA)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OCDMA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OCDMA技术的OCDMA-PON、隐匿通信等应用。

OCDMA technology is the next generation optical technology that can used in-optical channel mul- tiplexing, 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 included hidden communication based on OCDMA, OCDMA over PON are discussed.
