The Viavi (formerly JDSU) MTS/T-BERD 2000 is a compact, portable mainframe platform designed for field testing of fibre optic networks. Its modular architecture allows technicians to combine a range of test modules — including OTDR, power meter, and visual fault locator — in a single handheld device, making it well suited to installation, maintenance, and troubleshooting of singlemode and multimode fibre infrastructure.

The 4126 MA2 singlemode OTDR module delivers dual-wavelength measurements at 1310 nm and 1550 nm, enabling comprehensive characterisation of singlemode fibre links including splice loss, connector reflectance, and fibre attenuation profiling.
