Viavi's high-frequency field tester will help Comcast, others transition to DOCSIS 3.1

Viavi Solutions has introduced a new field test tool designed specifically for extended DOCSIS 3.1 frequency ranges, 240 MHz upstream and 1.2 GHz downstream.

Milpitas, Calif.-based Viavi says the new features have been added to its OneExpert CATV product, a new platform, introduced in March, designed to help operators performing hybrid fiber-coaxial (HFC) network upgrades and delivery gigabit-speed services. 

The vendor introduced the new platform at ANGA Com in Cologne, Germany this week. 

The platform includes an embedded DOCSIS 3.1 modem to help enable full service testing up to 1 Gbps. It is also backward compatible for testing DOCSIS 3.0 with 32X8 bonding, and it combines 204 MHz/1.2 Ghz network alignment and sweep in one instrument. 

Another element of this product is that it can support cable MSOs that decides to deploy FTTH. Cable operators have been deploying FTTH in some markets where it can prove a business case. 

"Wireline and wireless service providers worldwide are planning and building out networks to deliver gigabit connectivity to subscribers, and Viavi is proud to offer comprehensive test, measurement and assurance platforms to support them," said Rob Flask, director of product line management for Viavi Solutions, in a statement. "We have anticipated the European cable industry moving further ahead than the rest of the world in expanding their HFC networks, and have delivered a solution tailored to their needs."

While Europe is further ahead than the U.S. in terms of DOCSIS 3.1 deployment, American MSOs are ramping up. On Monday, for example, Comcast (NASDAQ: CMCSA) announced that will follow up rollout of the technology in Atlanta with deployment in Nashville, Tenn.
