The SC/APC grating reflector is installed at the user terminal of the grating distribution network and uses fiber grating to reflect the optical fiber line signal (1625nm+/-5nm, +/-10nm, or 1650+/-5nm, +/-10nm). Just connect the optical measurement system to the front section of the optical fiber network splitter. When the presence of the center wavelength is detected, the fiber connection of the user end is normal. If the center wavelength does not exist or the reflection value is low, it indicates that the user end fiber is damaged or broken and needs maintenance. So as to realize the online and fast detection of line on-off. However, other communication wavelengths are no longer at the inherent reflection wavelength of the fiber grating, and will normally pass through with low loss and will not affect normal communication.
