常规光纤非线性对色散补偿光纤位置的影响

The Influence of Optical Nonlinearities to the Position of the Dispersion Compensation Fiber for Dispersion Compensation

通过数值计算的方法分析了色散、自相位调制和激光器啁啾等因素对10Gb/s 100km G.652光纤通信系统的综合效应。对10Gb/s G.652光纤系统中用色散补偿光纤(Dispersion Compensation Fiber.即DSF)的两种方案进行了比较。然后简单讨论了色散补偿光纤在密集波分复用(DWDM)中的应用,最后给出通过以上分析得出的结论。

The combined effects of chromatic dispersion, selfphase modulation and laser chirp are numerically investigated for a 10Gbit/s IM - DDsystem over 100km of standard single-mode fiber. Precompensation and postcompensation of the chromatic dispersion based on Dispersion Compensation Fiber is compared. The application of DSF in DWDM is simply disgussed and the conclusion is given at last.
