1625nm High Accuracy SC APC Optic Fiber Bragg Grating FBG Reflector
The FBG reflector is a standard SC type connector 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 (1650 +/- 5 nm) 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. 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.
Characteristics
(1) High stability and reliability.
(2) Remote real-time detection.
(3) Low insertion loss.
(4) Easy connection for adapter structure.
Application
The SC pigtail fiber (FBG) reflector provided by Hangalaxy has the advantages of low insertion loss, high reflectivity, convenient installation, etc., and is an ideal optical device for network link monitoring; It is widely used in PON network,OTDR testing, central computer room testing, FTTX and other fields.

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.
