Viavi has unveiled what it describes as “rugged new solutions for fast, precise field testing” at the ANGA COM expo in Cologne, Germany. The new test and measurement solutions are designed to help service providers and contractors validate, qualify and troubleshoot cable and fibre broadband networks. The DSP TDR Time Domain Reflectometer and the OCC-4056C DWDM Optical Channel Checker, are said to deliver fast and accurate performance analysis and troubleshooting to ensure successful network installation and operation.

Multiple system operators and cable technicians are under enormous pressure to deploy new services in a timely manner, as well as to quickly and accurately find cable faults to restore service as soon as possible. Moreover, in today’s evolving landscape, the stakes are even higher as cable networks are now positioned to take on a larger role in mobile backhaul for 5G with new capabilities enabled by DOCSIS 3.1 and distributed architectures such as Remote PHY.

“We are at the forefront of testing technologies, such as Remote PHY, 5G, DOCSIS 3.1 and FTTH/PON, providing a reliable path through any access technology transition across the network lifecycle,” said Kevin Oliver, Viavi’s VP and General Manager, Converged Instruments & Virtual Test. “Our solutions enable network technicians to successfully deploy, maintain, optimise and evolve complex networks, delivering outstanding quality of experience.”

The new DSP TDR offers “lab-grade” functionality in a rugged, handheld form factor to accurately locate cable breaks or faults in the field, enabling outages to be addressed quickly for faster restoration of service. In addition to reducing mean-time-to-repair, the capability to precisely pinpoint a cable break helps limit the length of cable to be dug up for repairs, which means that operators can avoid paying for unnecessary span replacements.

This DSP TDR uses “step” technology that continuously transmits while the receiver simultaneously listens for reflected signals, resulting in more accurate fault detection. Additional features of this new solution include: data upload and retention with StrataSync cloud-hosted management solution to cut outage time and simplify documentation; simple setup and operation with an easily accessible, one-button event list; and a rugged design and “industry-leading” battery life for field use.

The OCC-4056C: As Dense Wavelength Division Multiplexing (DWDM) technology migrates into access networks, MSOs and mobile operators require new solutions for testing fibre links, 5G fronthaul networks or Remote PHY architectures. The new VIAVI OCC-4056C Optical Channel Checker is designed to work with the popular T-BERD/MTS-2000, 4000, and 5800 platforms, forming the industry’s most comprehensive set of test solutions for DWDM and hybrid DWDM/ CWDM metro and access networks.

At ANGA COM 2019, to be held June 4-6 in Cologne, Germany, Viavi will demonstrate these new products, alongside a comprehensive portfolio of broadband network testing solutions, (Hall 7, Stand B31). In addition, the company’s David Hering will deliver a presentation entitled “Great Wires Make Great Wireless – How Remote PHY and DOCSIS 3.1 Are Enabling 5G To Become the Next Killer App for Cable” during the “Migration to Fibre Enables new Business Opportunities” conference session on June 6 at 2:30 p.m.
