Customized SC Fiber Optic Reflector for Remote Monitoring of FTTx

Reflection wavelength :

Customized SC/APC FBG Fiber Reflectors, 1650nm, 1625nm, 1550nm or other wavelengths options, Female/Male Adapter type or Fiber Pigtails type options

Optical fiber (FBG) reflector, also known as fiber Bragg grating filter, is usually installed at the front end of an optical network ONU. Combined with OTDR equipment, it can realize optical link point-to-point (PTP) or point-to-multipoint (PTMP) network monitoring, which can be fast,accurately reflect network abnormalities.


  • Standard size, quick installation
  • High-precision ceramic ferrules 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


  • FTTX
  • Data center
  • OTDR test
