Optimized Design of Bandwidth of a F P Filter in ASK Modulation WDM Transmission Systems

提出了采用幅移键控（ＡＳＫ）调制的波分复用（ＷＤＭ）系统中光滤波器带宽的优化设计问题。并根据对长距离波分复用系统中影响信噪比的主要因素的分析，计算了优化设计问题。

An optimized design of bandwidth of a F P filter in ASK modulation WDM transmission systems is studied in this paper. The main interference on SNR of a long haul WDM transmission system is analyzed. An optimal bandwidth of F P filter in a long haul ASK modulation WDM system is found, and the numerical simulation confirms the result.
