摘要
设计了利用啁啾光纤光栅(CFG)对10Gbit/s光信号进行色散补偿的仿真模拟系统,该模拟系统研究了5种不同的色散补偿方案对系统误码率的影响,选出了最佳的一种补偿方案.模拟研究了入纤光功率对系统误码率的影响,结论是在保持光探测器接收功率不变的条件下,入纤光功率越高,误码率越大.对于最佳色散补偿方案,入纤光功率为6dBm时既能保证较高的传输功率又有较好的误码性能.
We designed a 10 Gbit/s simulation system whose chromatic dispersion was compensated by chirped fiber Bragg gratings. We researched the influences of five compensation methods on system bit error rate (BER) and selected the best one. We investigated the influence of input fiber optical power on system BER and the conclusion was that the system BER increased with the increase of input power. For the best compensation method, the system had both high transmitting power and low BER when the input was 6 dBm.
