Cable ops make 'massive' DOCSIS deployments

With the ability to offer technology now established in mainstream marketing by such firms, cable operators are now ramping up DOCSIS 3.1 services and shifting to remote/distributed access, says IHS research.

After conducting interviews with global cablecos that collectively control 87% of the world's cable capex, the analyst found that 42% plan to deploy distributed access architectures (DAAs) by 2017, with respondent operators citing R-PHY, R-MACPHY and R-CCAP as their primary choices for architectures.

The research also found that operational benefits cable operators are reaping from moving from CMTS to CCAP are just the first step in a long-term transition to distributing data processing capabilities throughout the network. Respondents, on average, said that about a third of their residential subscribers will be passed by DOCSIS 3.1-enabled headends by April 2017.

Nearly half of respondents added that by 2017 they will likely have return path (upstream) frequencies of 86-100MHz, while a quarter will have 101-200MHz of return path spectrum.

"Cable operators are clearly committed to both DOCSIS 3.1 and distributed access architectures to increase bandwidth in their access networks. Though there is no consensus yet on which distributed access technology most will use, there's no question they will distribute some portion of the DOCSIS layer to their optical nodes," said Jeff Heynen, research director for broadband access and pay-TV at HIS and author of the CCAP, DOCSIS 3.1, and Distributed Access Strategies and Vendor Leadership: Global Cable Operator survey.
