针对传统波分系统验收指标存在的不足,提出利用传输网管对设备的纠错前误码率性能检测指标来衡量波分系统的冗余度,从而及时发现波分系统是否存在冗余度不足的问题,工程和维护人员通过排查解决影响波分系统的光功率,色散补偿、信噪比、非线性效应及设备硬件质量等原因,确保波分复用系统的建设质量,为业务通信网络安全稳定运行提供有力的保障。 Aiming at the shortcomings of the traditional WDM system, this paper proposes to use the transmission network management system to measure the WDM system redundancy before the error correction performance of the device, so as to discover whether the WDM systems have insufficient redundancy The problems, engineering and maintenance personnel can ensure the construction quality of the WDM system by investigating and resolving the optical power, dispersion compensation, signal-to-noise ratio, nonlinear effect and equipment hardware quality of the WDM system, and ensure the security and stability of the service communication network Run to provide a strong guarantee.
