光功率在线测量方法及应用

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。

Online Measurement of Optical Power and Its Applications

Fiber protection equipment must usually measure the optical transmitted power and received power,check the attenuation and judge whether the received power is in normal condition,which asks for considerable workload and often results in man-made errors.In order to overcome these shortcomings,this paper presents an online measuring method of optical power.With the fiber protection equipment,the received power can be measured without disconnecting the fiber,more quickly and with less harm done to the fiber channel.
