Optical Fiber Reflector
The reflector for 1650 nm reflects all wavelengths from 1645 nm to 1655 nm. With its low insertion loss at the transmission wavelength range and high reflectance at the reflected wavelength range it is the ideal optical termination for link monitoring of FTTx networks , FTTx reflectors are suitable for both point to point (PTP) and point to multipoint (PTMP) networks. They are preferably installed at the subscriber’s homes in order to highlight these positions in the OTDR trace by distinct reflections of the test signal.

▪ Wavelength optional
▪ Compact Design
▪ Shape similar to the attenuator
▪ High sensitivity
▪ FBG in the ceramic ferrule, not affected by dirt
▪ Mate with normal adapter, very convenient to use



▪ Create high reflectance at the termination of a PON without disturbing traffic
▪ Test reflectance from the central office
▪ Check optical continuity of subscriber when being added or when troubleshooting
