Viavi Takes DOCSIS 3.1 to The Test

Viavi Solutions has introduced a DOCSIS 3.1 field test platform that features the extended frequency ranges supported by the emerging multi-gigabit platform for HFC networks – 204 MHz upstream and 1.2 GHz downstream.

Viavi said the new capabilities is built on OneExpert CATV, a new platform that helps operators with HFC network upgrades. The vendor will be showing off its handiwork at ANGA Com in Cologne, Germany. 

The company said the platform embeds a D 3.1 modem, but also supports DOCSIS 3.0 with 32x8 channel bonding with software-upgradability for DOCSIS 3.1 testing.

Viavi’s enhanced D3.1 field testing capabilities appear as MSOs prepare to expand their tests and trials of the technology, which is designed to support up to 10 Gbps down and at least 1 Gbps upstream.  CableLabs is also working on a “full duplex” enhancement for D3.1 that will enable symmetrical speeds over HFC. Earlier Monday, Comcast announced it had kicked off a D3.1 consumer trial in Nashville, following up an earlier launch in Atlanta. 

However, Viavi said MSOs in Europe are already requiring vendors to provide DOCSIS 3.1 service test and 204 MHz/1.2GHz sweep in one instrument, and expects that feature to be adopted worldwide to other operators as they update their HFC networks.

“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 at Viavi, said 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."
