OCI High-resolution Optical Link Diagnostic Instrument

OCI High-resolution Optical Link Diagnostic Instrument


OCI is an ultra-high precision optical link diagnostic instrument. By using optical frequency domain reflection(OFDR) technology, a single measurement can achieve a full range of diagnosis from optical devices to the optical links. OCI’s event point positioning accuracy can be up to 0.1mm, which means it can easily identify macrobends, connection points and break points in the optical fiber links, and accurately measure parameters such as return loss, insertion loss, and spectrum. Moreover, by adding the optional distributed optical fiber sensing function, OCI can achieve high-resolution measurement of strain and temperature.
