Abstract : this article introduces the structure of dwdm networks and some applications of fiber bragg grating 文摘:介绍了dwdm网络的结构特点以及光纤光栅在其中的一些应用
The desinged wide band net is composed of five 80gb / s dwdm loop routes and one 80gb / s dwdm chain route 所设计和实现的宽带传输网为5个80gb s的dwdm环路及一个80gb s的dwdm链路。
Dense wavelength division multiplexing ( dwdm ) is a new communication technology that is rapidly progressing during recent years 密集波分复用( dwdm )是近年迅速发展的一种光纤通信新技术。
So it can be expected that two - segment dfb lasers will play important roles in future dwdm and multi - wavelength network 因此，两段式dfb激光器可望在密集波分复用以及多波长网络中获得应用。
As interleavers have a fairly high cost performance , they have been extensively used in narrow interval dwdm systems 摘要梳状分波器由于具有较高的性价比，在窄间隙密集波分复用系统中已大量使用。
