The Viavi (formerly JDSU) MTS 6000 is a high-performance modular field test platform designed for the installation, maintenance, and troubleshooting of fibre optic networks. The touchscreen mainframe accepts a range of interchangeable test modules, enabling technicians to configure the instrument for diverse fibre measurement tasks from a single portable unit.

The 8126B singlemode OTDR module provides dual-wavelength operation at 1310 nm and 1550 nm, delivering high dynamic range performance suitable for long-haul spans up to 400 km. The extremely short event dead zone of 0.65 m allows detection of faults very close to the launch point, while the 2 m attenuation dead zone ensures accurate loss measurements on short links. The APC connector interface maintains low back-reflection during testing.
