The Coherent OTDR MW90010B can measure ultra-long submarine cables of up to 20,000 km to locate faults with 10 m measurement resolution.

Coherent detection technology of the Coherent OTDR captures a comprehensive range of waveform data, including fault location, cable loss, bending loss, and fiber length. This ensures a detailed evaluation of submarine cables, providing you with all the necessary information for your maintenance and evaluation needs. Its excellent basic performance, such as measurement time and dynamic range, accurately measures submarine cables with optical-amplifier repeaters separated by distances of 80 km or more.
Moreover, setting the built-in tunable light source with a wavelength accuracy of ±0.05 nm to a wavelength range of 1527.60 nm to 1567.13 nm supports the measurement of DWDM submarine cables.
