OCI High-resolution Optical Link Diagnostic System

OCI High-resolution Optical Link Diagnostic Instrument


OCI is an ultra-high precision optical link diagnostic instrument based on Optical Frequency Domain Reflectometry (OFDR) technology. With a single measurement, it can achieve comprehensive diagnostics from devices to the entire link. OCI effortlessly locates and identifies macro-bends, connection points, and breakpoints in the optical fiber link, while accurately measuring parameters such as return loss, insertion loss, and spectrum. The event point positioning accuracy of OCI reaches up to 0.1mm. OCI is not only used for optical link diagnostics but also extends its capabilities to distributed optical fiber sensing, enabling high-resolution measurements of strain and temperature.
