Design and Implementation of High-performance Local Area Cwdm Network with Technique

采用波长间隔为 10～ 2 0nm的CWDM(coarsewavelengthdivisionmultiplexing)技术 ,设计完成了高性能波分复用计算机局域网。采用该设计方案可把现有的单波长光纤局域网无缝升级为多波长网络 ,不仅提供网络带宽的升级 ,同时实现网络结点间的波长路由功能 ,减小了数据包在网络中的通信延迟。为实现网络规模的扩展 ,本文同时在 85 0nm和130 0nm窗口设计了两种光纤网卡。实验证明 。

A high-performance local area network (LAN) is designed with 10～20 nm separated coarse wavelength division multiplexing (CWDM) technique. Using this design scheme, single-wavelength optical fiber LAN can be seamlessly upgraded to multi-wavelength LAN. Not only the bandwidth of the LAN can be upgraded, wavelength routing function can also be achieved. As a result, the data packet communication latency can be decreased. To expand the scale of the network, two kinds of network interface cards have been designed using laser diodes at the 850nm and 1300nm wavelength windows respectively. The experiment indicates that CWDM technique can be implemented at the two wavelength windows simultaneously.
