The OTDR FBG Reflector leverages Fiber Bragg Grating (FBG) technology to offer a reliable and high-performance solution for optical network testing. With a wide bandwidth and low insertion loss, this reflector is designed to reflect the OTDR test signal with precision, ensuring accurate measurements without interrupting live network traffic. It reflects at the intrinsic wavelength of 1644.5nm to 1655.5nm, ideal for use in testing the reflectance from central offices and optical continuity of subscribers during network setup or troubleshooting.
