The Viavi MTS 6000A V2 is a compact, modular mainframe platform designed for field testing of optical fibre networks. It accepts a wide range of plug-in test modules, allowing technicians to configure the instrument for their specific network testing requirements. The touch-screen interface and portable form factor make it well suited to both in-the-field and depot testing environments.
The 8126 VLR (Very Long Range) Singlemode OTDR module is engineered for demanding applications across short haul access networks, FTTx, point-to-multipoint (P2MP), long haul, and very long haul infrastructure. Its high dynamic range and minimal dead zones enable accurate characterisation of splice loss, connector reflections, and fibre faults even on the longest spans.
