An optical time-domain reflectometer (OTDR) is a specialized device used to test and analyze fiber optic networks. It detects defects, signal loss, breaks, and connector issues along the fiber, while also helping to pinpoint fault locations with high accuracy. Beyond troubleshooting, an OTDR measures key performance parameters such as fiber length and overall quality. Our OTDR devices support multiple optical connector types, including FC, LC, SC, and ST, ensuring compatibility with a wide range of fiber optic network equipment.
