摘要
搭建通信速率为10 Gbps的光DPSK调制发射、自相干接收单元实验测试平台。采用光相位调制和自相干接收技术实现光DPSK系统设计。为稳定输出信号解决相位漂移,发射单元设计出自适应增益控制单元和交叉点自适应控制单元。在系统测试平台上,完成差分编码模块、发射单元和自相干接收单元及系统性能测试。实验室环境条件下,测得系统接收单元灵敏度为-48 dBm,通信系统误码率优于1×10-7;误差矢量幅度为7%,通信性能较好,满足系统设计指标要求。
An experimental test platform for 10Gbps optical DPSK modulation-emission and auto-coherent receiver unit is constructed.The optical DPSK system is designed using optical phase modulation and self-coherent receiving technology.In order to stabilize the output signal and solve the phase drift,the adaptive gain control unit and the adaptive control unit are designed.On the system test platform,the differential coding module,transmitter unit,self-coherent receiver unit and system performance test are completed.The sensitivity of receiving unit is-48 dBm,the bit error rate of the communication system is better than 1×10-7,the EVM(error vector amplitude)is 7%and the communication performance is better.
