摘　　要：提出了一种差分八相移键控/反转归零码(D8PSK/IRZ)正交调制的光标记方案。该方案采用D8PSK进行载荷信号调制,IRZ进行标记信号调制,实现D8PSK/IRZ的正交光标记调制。仿真实现了传输速率为120 Gbit/s的D8PSK/IRZ正交信号的百公里传输,在仿真系统接收端得到了较好的信号眼图,且在最佳消光比时系统有较小的误码率,使得该方案的可行性及有效性得以验证。A novel optical labeling scheme based on differential 8-level phase-shift keying（D8 PSK）/Inverse-return-to-zero（IRZ）orthogonal modulation is investigated. In this scheme,D8 PSK is used as the modulation formats of the payload signal,whilethe label signal uses IRZ as its modulation formats. The results of simulation show that better performance can be achieved after thetransmission in 100 km optical fiber while the transmission rate of 120 Gbit/s.
