Fiber Optic Reflectors for FTTx Network Link Monitoring

Thursday, July 21, 2022
AtGrating Technologies Co. Ltd.

In the PON (Passive optical network), especially the complex point-to-multipoint PON ODN (Optical distribution network) topology environment, the rapid monitoring and diagnosis of optical fiber faults has become a challenging work. Although optical time domain reflectometer (OTDR) tools are widely used at present, OTDR detection is sometimes not particularly sensitive to the attenuation of optical signals at the ends of some ODN branch fibers or ONU fibers ends. Installing a low-cost wavelength-selective fiber optic reflector on the ONU side is often used at present, through which accurate detection of the end-to-end attenuation of the optical link can be achieved.
