Yilut's 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 -1655.5 nm.
Features
High precision of reflectance at test wavelength Low insertion loss at traffic wavelength
Easy to install
Exceptional reliability and environmental stability Applicable for FTTH、FTTB、 FTTC
Compatible with GPON、EPON、GEPON、10GEPON、NGPON
Applications
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
