An OTDR (Optical Time Domain Reflectometer) is a measuring instrument intended to measure the transmission loss and distance of optical fibers, locate cable cuts, and evaluate the connection loss and reflectance (return loss) of fusion splices, mechanical splices, connector connections, etc. Also known as a fault locator, the OTDR is used for the installation and maintenance of optical fibers.
Anritsu provides a vast range of OTDR products capable of fault diagnosis and optical transmission characteristic analysis for multicore optical fibers, submarine optical cables exceeding 10,000 km in length, PONs, and long-distance optical fibers exceeding 200 km in length.
