The Viavi (formerly JDSU) MTS 5800 is a high-performance, modular telecommunications test platform designed for installation, commissioning, and maintenance of SDH, SONET, PDH, and Ethernet transport networks. It combines a portable mainframe with interchangeable test modules — such as the 5801P — giving field engineers the flexibility to tackle a broad range of network technologies with a single instrument.

The MTS 5800 is widely used by network operators and equipment vendors for turn-up testing, performance monitoring, and fault diagnosis on both legacy and next-generation transport networks. Its touchscreen interface, modular architecture, and comprehensive protocol support make it one of the most capable portable testers in its class.
