摘　　要：为了使信号能有效地在光纤中传输,提出了一种基于色散补偿光纤(DCF)与电子均衡器相结合的色散补偿技术,即在传输链路上采用DCF前置补偿/后置补偿,接收端进行电子均衡补偿。在optisystem15仿真软件中搭建了40Gbit/s的传输系统对非归零码NRZ信号的色散补偿仿真,通过与DCF前置补偿及后置补偿比较,在入纤功率较高及传输距离较长时,该系统有较高的Q值以及相对较低的误码率,结果表明该系统性能良好。In order to effectively transmit signals in optical fiber,a dispersion compensation technology based on DCF and electronic equalizer is proposed,that is,DCF pre-compensation/post-compensation is used in the transmission link,and electronic equalization compensation is used at the receiver.In OptiSystem15 simulation software,a 40Gbit/s transmission system is built to simulate the dispersion compensation of NRZ signal of non-return to zero code.Compared with DCF pre-compensation and post-compensation,the system has higher Q value and relatively lower bit error rate when the fiber input power is higher and the transmission distance is longer.The results show that the system has good performance.
