The FBG reflector is a standard SC/LC type connector structure, which package a special FBG in the ceramic ferrule.
This 1550nm LC/UPC FBG Reflector fiber bragg grating reflector is a low-cost specific band reflector mounted on the optical network unit (ONU) side. It can reflect light pulses (1550 +/- 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.
Characteristics:
- High stability and reliability
- Remote real-time detection
- Low insertion loss
- Easy connection foradapter structure
- Compliant with Telcordia GR-326-CORE, Telcordia GR-1221-CORE
- Compliant withRoHS
Application:
- Detection and maintenance of Passive Optical Network lines (applied to FTTx).
