VIAVI Introduces Industry's Smallest Handheld Network Tester for Next-Generation Mobile and Cable Networks

May 31, 2018 — VIAVI is excited to announce the availability of the new T-BERD/MTS 5882 which provides portable testing for emerging 5G and Remote PHY technologies, simplifies the applications for technicians and contractors, and is 20% smaller than the next smallest competitor. The T-BERD/MTS 5882 packs critical features to enable fiber installation, multi-protocol service activation, troubleshooting, and maintenance for next-generation mobile and cable networks into the industry's smallest form factor for this category of instrument.

Emerging network architectures require timing distribution technologies such as IEEE 1588v2 Precision Timing Protocol to synchronize distributed equipment. For example, in mobile networks distributed 5G radios interoperating with LTE macro cells, in cable networks distributed remote phy devices (RPD) require synchronization for proper DOCSIS functionality, and in utility networks for the synchronization of distributed power transmission equipment. In all cases ensuring that equipment is properly synchronized is critical for high quality network operation. The T-BERD/MTS 5882 makes testing these complex technologies easy for technicians of all skill levels across hybrid workforces.

The move to 5G, Remote PHY and other distributed technologies means even more stringent synchronization targets must be met to prevent service degradation. Based on VIAVI's leadership in fiber and communications network testing, and the company's collaboration with Tier-1 service providers, the T-BERD/MTS 5882 solution addresses these critical requirements. This instrument is optimized for fiber characterization, multi-protocol service activation, troubleshooting and maintenance across mobile, cable and power utility networks.

Key features include:

  • Built on the proven platform of the T-BERD/MTS 5800, making it the smallest instrument in its category in the industry
  • Support for emerging and legacy network protocols such as Ethernet, CPRI, eCPRI, OTN, and PDH
  • Built-in GNSS receiver
  • Enhanced diagnostics for microwave backhaul installation/maintenance
  • Extended battery life and fast battery recharge
  • Job Manager application that consolidates and automates testing and reporting; resulting in industry-leading job accuracy and timely completion

"With this one solution, VIAVI is delivering on the promise of two major industry trends – the evolution of networks to deliver Gigabit speed to the end user, and greater workforce efficiency through automation," said Kevin Oliver, Vice President and General Manager, Converged Instruments and Virtual Test, VIAVI Solutions. "The T-BERD/MTS 5882 supports the more advanced requirements of 5G and Remote PHY, enabling technicians and contractors of all skill levels to complete their work quickly and accurately. It's an essential tool for mobile, cable, and utility network operators."
