摘　　要：数据擦除机制是未来宽带接入网络的最经济、最具前途的方案。本文建立基于注入法布里-珀罗(FP-LD)激光器数据擦除式的载波再调制无色双向波分复用无源光网络(WDM-PON)模型,在10 Gbit/s速率下比较FP激光器的偏置电流、消光比、限制因子和注入功率等参数对数据擦除效率的影响。仿真采用Optisystem 15.0软件,设定注入功率为-25~-5 dBm,偏置电流为20~100 mA。结果显示,该模型具有较好的擦除性能,并且能够抑制下行残留消光比小于0.5 dB。Data erasure mechanism is the most economical and promising option for future broadband access network.In this paper,a carrier re-modulated colorless bidirectional wavelength division multiplexing passive optical network(WDM-PON)model based on data erasure of injected Fabry Perot(FP-LD)laser is established.The effects of bias current,extinction ratio,limiting factor and injection power on the data erasure efficiency of FP lasers at 10 Gbit/s are analyzed.The simulation uses Optisystem 15.0 software,the injection power range is-25 dBm to-5 dBm,and the bias current is 20 mA to 100 mA.The results show that the system has good erasure performance and can restrain the residual extinction ratio of downlink less than 0.5 dB.
