1. Descriptions 
Fiber reflector, also known as fiber Bragg grating filter, is usually  installed in the front end of ONU of optical network. Combined  with OTDR equipment, it can realize the point-to-point (PTP) or point-to-multipoint (PTMP) network monitoring of optical link, which can reflect the network abnormality quickly and accurately; The SC fiber (FBG) reflector provided by surfiber has  the advantages of low insertion loss, high reflectivity, convenient  installation, etc., and is an ideal optical device for network link  monitoring; It is widely used in PON network、OTDR testing, central computer room testing, FTTX and other fields.
