基于光纤CDMA技术的全光网实现

Implementation of All-Optical Network base on OCDMA

对基于光纤CDMA(OCDMA)技术的全光网进行了研究。分析了OCDMA技术应用于全光网的优点:如多用户可扩展性,好的保密性等。文章还介绍了OCDMA应用在全光网所采用的硬件结构,重点阐述了光纤的选择、光收/发模块的设计及基于系统集成设计的可调光编/解码器的设计。最后探讨了全光网具体实现中存在的一些问题,得出结论:OCDMA技术是实现全光网传输的比较好的备选方案之一。

This article researches the all - optical network base on OCDMA technology. The author analysis the virtue of OCDMA technology when implementing in all - optical network like： multi - user expansibility and excellent security character. Also, this article introduces the hardware structure that OCDMA adopted, expatiate the fiber choosing, optical transceiver and tunable optical coder/decoder design. At last, the author put forward some practical problem existing in the implementation of all - optical network and draws a conclusion said： OCDMA technology is comparatively a perfect solution for all - optical network transmission.
