摘要
为了防止光纤暴露在外对人体特别是眼睛造成伤害,同时也为了保护OTN光放大器设备,在主光通道上的一段或多段中继段上的光功率信号丢失时,系统提供自动功率调整即IPA功能,系统光信号恢复正常后,又恢复光系统的正常工作。
In order to prevent the fiber from being exposed to the human body, especially the eyes, and also to protect the OTN optical amplifier device, the system provides IPA function, the automatic power adjustment, when the optical power signal on one or more segments of the main optical channel is lost. After the system optical signal returns to normal, the normal operation of the optical system is restored.
