A co-propagation optical time-domain reflectometer (C-OTDR) is a test instrument used to locate fiber faults in amplified submarine cables. C-OTDR testing supports cable deployment, commissioning, troubleshooting and post-repair validation, helping operators assess cable integrity and make informed repair decisions.
EXFO’s USO-1618 submarine OTDR locates faults in only 3 minutes per fiber pair. It combines automated fault analysis with an intuitive optical link view and supports both rackmount operation in landing stations and portable use aboard repair vessels.
