可调谐滤波器在DWDM系统中的应用

Tunable optical filters and their applications in DWDM

可调谐滤波器是实现未来全光网络的重要器件,在DWDM系统中有着广泛应用。文章介绍了几种常用的可调谐滤波器的原理、最新研究及其在可重构光分插复用和光传输性能监测中的应用。

Tunable optical filters are essential for the performance in future all optical network. They are also widely used in DWDM system. We introduce the recent research on the typical tunable optical filters and their applications in DWDM, such as reconfigurable optical add/drop multiplexer （ROADM） and optical performance monitor （OPM）.
