The Viavi Solutions MP OTDR module provides the optimum performance that fiber installers and service providers need to test metro, cable TV (CATV), and FTTH networks with high-port-count splitters. With various wavelength combinations including filtered wavelengths for in-service testing, an improved dynamic range, and optimized resolution and dead zones at short pulses, the MP module is the ideal OTDR to test any PON system with up to a 1x128 splitting ratio. The MP module’s optical performance, combined with the T-BERD/MTS platform’s complete suite of features, ensures that testing is done right the first time.
