摘要
光码分多址(OCDMA)技术近年发展迅速,将成为宽带光纤通信网的主要扩频技术之一.详细分析了OCDMA系统网络的结构原理、组网技术、光交换技术;较为全面地论述和评价了几种主要的光编码器、光解码器的实现方案、技术特点和应用范围;重点讨论了基于布拉格光纤光栅阵列波导光栅的光编界解码器的编解码原理和实现技术.分析了OCDMA技术在现代光纤通信中的应用前景.
Abstract
ptical code division multiple access (OCDMA) system is one of the most competitive multiplexing technologies and will be widely applied in the field of optical communication. The scheme fiber-optical OCDMA system was analyzed in details. The strategies in the designing of encoder/decoder were compared and evaluated. Especially, the encoder/decoders based on fiber Bragg-grating and arrayed guide grating are discussed. The future application of OCDMA in the field of optical communication is predicted.
