- • Create high reflectance and wide working bandwidth at the termination of a PON without disturbing traffic
- Test the reflectance from the central office.
- Check optical continuity of a subscriber when being added, or when troubleshooting
OTDR FBG Reflector
OTDR FBG Reflector is based on Fiber Bragg Grating technology with wide bandwidth
and low insertion loss to reflect OTDR test signal. When the optical measurement system
generates a certain range of wavelength to a Passive Optical Network (PON) which can
pass through the FBG, the FBG will reflect its own intrinsic reflection wavelength at
1644.5nm - 1655.5nm.

*①REF-1650-XX-XX，the first XX means fibre type，the second XX means structure type
*② Insertion Loss (dB) = -10 log
(Output Power/ Input Power) [dB]
*③Reture Loss (dB)=-10 log(Reflected Power/ Input Power) [dB]. To measure the return loss of reflect band, the light of 1650nm should be injected from the female side of reflector
