对设备的可靠性研究是实现设备持续保障的条件。首先分析了光纤通信传输系统中波分复用设备的功能及配置,建立了波分复用设备的可靠性框图模型。然后根据建立的可靠性框图模型及相关数学模型,计算分析得出波分复用设备可靠性指标的预测值。最后将预测值与实际值进行了比较,结果表明,预测值非常接近实际值,从而验证了所建立的可靠性模型用于设备可靠性指标的预测是可行的。

The function and configuration of the Wavelength Division Multiplexing equipment in the optical fiber communication transmission system was analyzed,and the reliability diagram model of the Wavelength Division Multiplexing equipment was established. Then the predictive value of the equipment reliability index was calculated based on the reliability diagram model and the related mathematical model. By comparing the predictive value and the actual values,it shows that the predicted values is very close to the actual value,so the feasibility of the reliability model used to forecast the reliability index of the equipments is verified.
