1625nm LC/APC Fiber Optic Reflector FBG Male-female Adapter Type


LC/APC Male-Female Type 1625nm FBG Fiber Optic Reflector, ideal for GPON ONU OTDR testing

This 1625nm fiber reflector is a standard LC/APC adapter female-male structure, which package a special FBG in the ceramic ferrule. The fiber bragg grating reflector is a low-cost specific band reflector mounted on the optical network unit (ONU) side. It can reflect light pulses (1625 +/- 5nm) from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally. So the OTDR can determine whether the fiber line is normal by detecting the signal reflected by the fiber grating reflector. When the reflected signal is lower than the normal value, the line loss is too large; when the reflection value is 0, the optical fiber line is broken. Therefore, we can maintain the fiber line in time by the real-time monitoring of the fiber line. The LC fiber reflector provided by LightOptics has the advantages of low insertion loss, high reflectivity, and easy installation. It is an ideal optical device for network link monitoring.
