摘要
针对40 Gbps光传输系统中存在的色散问题,利用光域补偿速度快、非线性小等优点,设计了一种啁啾光纤光栅补偿系统,并在OptiSystem7.0环境中,对该系统的色散(PMD)补偿效果进行了仿真,通过性能分析表明采用啁啾光纤光栅后置补偿结构能够进行有效的色散均衡,最后还分析了入纤功率对系统性能的影响.
In order to compensate the dispersion in 40 Gbps optical links,the optical dispersion compensator was discussed because of its high compensation speed and small nonlinearity.An optical equalizer of the post compensation scheme was presented and the simulation results showed that the equalizer composed by chirped fiber grating can mitigate dispersion effectively.Further more,the incident power has been discussed in order to reduce the nonlinear effect.
