摘要
以PTDS仿真实验平台为基础,对传输速率为2.5 Gbit/s的光码分多址通信系统性能进行了研究。仿真研究了传输信道和光功率对光码分多址系统性能的影响,分析了传输距离、光纤色散系数、光纤衰减、入纤光功率等与误码率和Q值的关系。
The performances of 2.5 Gbit/s optical code division multiple access (OCDMA) communication system are investigated based on emulation experiments of PTDS (Photonic transmission design suite). The influences of length, dispersion index and attenuation index of transmission fiber and incident optical power on BER (bit error rate) and Q value of the system is analyzed.
