摘　　要：本文提出了一种正交调制光标记交换系统,将幅移键控(ASK)净荷与频移键控(FSK)光标记引入该系统,利用仿真对携带40Gb/sASK净荷和2.5Gb/sFSK标记的光标记交换系统传输的性能进行了验证。同时,通过对系统消光比(ER)与色散补偿方案进行优化,得到了传输性能最佳的ASK/FSK光标记交换系统模型:FSK标记与ASK净荷接收灵敏度在背靠背传输时分别达到-19.8d Bm与-16d Bm,传输100km后,功率代价小于5d B。A novel orthogonal modulated optical label switching system was proposed.Amplitude shift keying(ASK)payload and frequency shift keying(FSK)label are applied in our model.Transmission performance of optical label switching system with40Gb/s ASK payload and2.5Gb/s FSK label was demonstrated by simulation.Extinction ratio(ER)and dispersion compensation scheme were optimized in the model to improve received signal quality.At last,an optimal system model was obtained:sensibility of FSK label and ASK payload reaches-24.5dBm and-19.5dBm,respectively,and power penalty less than5dB after100km transmission.
