1650nm LC/APC Fiber Optic Reflector ideal optical for PON OTDR testing


LC/APC Fiber Optic Reflector 1650nm, Female to Male Adpater type, ideal optical for PON OTDR testing

The FBG reflector is a standard SC/LC 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 +/- 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.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.


  • LC optical fiber (FBG) reflector adopts male and female structure, standard size, convenient and fast connection
  • High-precision ceramic ferrules and sleeves are used to achieve high-precision alignment of the connectors to ensure long-term stable mechanical and optical performance
  • The optical fiber (FBG) reflector provided by LightOptics satisfies the working environment of -20~70℃, with an average of more than 500~1000 plug-in tests, stable performance and reliable quality
