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 captures waveform data, including fault location, cable loss, bending loss, fiber length, etc., for detailed evaluation of submarine cables. 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 measurement of DWDM submarine cables.
