OTDR

Model: Viavi MTS-4000 V2 OTDR

The Viavi MTS-4000 V2 OTDR is the essential tool for fiber optic network troubleshooting and certification. As an Optical Time Domain Reflectometer, it works by sending a pulse of light down the fiber and analyzing the light scattered or reflected back. This allows technicians to accurately measure fiber length, locate faults like breaks or poor splices, and quantify signal loss. Covering key wavelengths (1310, 1550, and 1625nm) and supporting PON networks, the MTS-4000 generates a detailed visual trace—a definitive map of the cable's health. This makes it indispensable for installation, maintenance, and ensuring long-term performance, solidifying its role as the cornerstone of modern fiber optic diagnostics.
