分析了光缆动态衰耗、光纤盘纤半径和环境温度三者之间的关系,通过一个光纤传输故障实例,说明了光缆盘纤半径小于40mm时,在北方冬季对光缆传输光特性产生的重要影响。
The relationship between dynamic attenuation of optical fiber cable, optical fiber radius and ambient temperature is analyzed. A failure case of optical fiber transmission is described, which shows the important influence on the transmission optical characteristics of optical fiber cable in winter in the north when the radius of optical fiber cable is less than 40mm .
