摘　　要：通过数值模拟研究了 1 6× 1 0 Gbit/s高速通信系统中非线性效应对系统误码率的影响 .模拟结果表明 :G.6 5 2光纤中存在的 SPM和 XPM非线性效应使得系统误码率随入纤光功率的增大呈现多级变化 ;入纤光功率的取值范围应为 9d Bm≤ Pin ≤ 1 6 d Bm.这些研究结论具有实用价值 .The influences of fiber nonlinear effects on 16×10 Gbit/s system are simulated and studied. From the simulation, the following conclusions are drawn: (1) SPM and XPM effects existing in G.652 fiber are main reasons for the irregular changes of system BER versus the input-fiber-power; (2) if the input-fiber-power is less than 16 dBm and larger than 9 dBm, the system design can be run smoothly.
