摘要
声光可调滤波器以其宽的调节范围、窄的滤波线宽、多信道并行滤光等特点,在光纤通信系统中作动态增益均衡器具有很多优点。用声光可调滤波器实现EDFA级联的WDM系统的动态增益均衡,可扩展增益带宽(~52 nm),提高传输距离 (~ 2400 km)。
Acoustooptic tunable filters have virtue of broad tuning range, narrow filter bandwidth, and simultaneous independent multiple-channel filtering, working as dynamic gain equlizer in optical fiber communication systems. In the latest system using acoustooptic tunable filters as gain equlizers, the gain band--width and transmission distance achieved 52nm and 2400km, respectively.
