中文摘要：

基于幅移键控／频移键控（ASK／FSK）正交调制光标记交换（0LS）系统工作原理，提出了一种利用光带通滤波器（OBPF）对FSK标记进行谱均衡的方法，从而有效改善ASK净荷接收灵敏度。利用仿真，对40Gb／sASK／FSK正交调制OLS系统，在使用3种不同类型OBPF进行谱均衡时的传输性能进行了验证与比较分析。结果表明，采用24GHz带宽巴特沃茨（Butterworth）滤波器可得到最佳谱均衡效果，使ASK信号接收灵敏度提高1．2dB，光信噪比（OSNR）性能提高0．5dB。

英文摘要：

A novel scheme of spectrum equalization for effectively improving receiving responsibility of amplitude shift keying （ASK） payload by applying an optical band-pass filter （OBPF） is proposed, which is utilized in amplitude shift keying/frequency shift keying （ASK/FSK） orthogonal modulation optical label switching system. The transmission performances of 40 Gbit/s ASK/FSK optical label switching system with three types of OBPFs are demonstrated and compared by simulations. The results reveal that a Butterworth filter with 24 GHz bandwidth shows the optimal spectrum equalization characteristics：1. 2 dB power penalty and 0. 5 dB optical signal-to-noise ratio （OSNR） penalty of the ASK payload could be obtained.
