光纤保护在通道告警或定检时,需要对光缆的入纤功率和出纤功率进行检测,校对光缆的传输衰耗,判断装置收信功率是否正常。这带来了大量的工作量,并容易产生人为隐患。为了避免出现这一情况,文中设计了一种光功率的在线测量方法。不需要插拔光纤,保护装置就能测量出光纤中的收信功率。由于测量时不需要断开光纤通道,因此该测量方法对光纤通道损伤小,避免了人为操作造成的通道隐患。
Optical fiber protection In the channel alarm or scheduled inspection, you need to test the optical fiber into the fiber power and fiber power, proofreading fiber transmission attenuation, to determine the device received power is normal. This has brought a lot of workload, and prone to human potential problems. In order to avoid this situation, an online measurement method of optical power is designed. Do not need to plug the optical fiber, the protection device can measure the receiving power in the optical fiber. Since the measurement does not need to disconnect the fiber channel, so the measurement of fiber channel damage is small, to avoid the human operation caused by the channel hidden dangers.
