First DOCSIS 3.1 Interop Opens for Vendor Registration

CableLabs is making progress on test plans and equipment “plugfests” for DOCSIS 3.1 that will lead the way to official product certifications and qualification testing in the first half of 2015.

The speed of that product development is only being matched by the speeds that DOCSIS 3.1 is designed to support – up to 10 Gigabits per second downstream and at least 1 Gbps in the upstream.

Preparing an already sophisticated network for the migration to the multi-Gigabit-capable DOCSIS 3.1 platform requires new technology and training strategies, but just as crucial to the eventual deployment of 3.1 are the business-side elements. Does it make dollars and sense?

Vendors in the DOCSIS 3.1 market, such as Cisco Systems, hope to rise with the tide as MSOs tap it to deliver fiber-like performance without having to pull fiber all the way to the home.
“The challenge is expanding plant. We started from the ground up with the 3.1 team and built in full spectrum analysis set up to compete with fiber,” Cisco CTO and engineering fellow John Chapman said. “Now, 3.1 becomes the tool of choice.”
And a tool that still remains somewhat of an enigma, Chapman said.

“The brutal reality is that no one can figure out why we need so much bandwidth,” he said. “But it sure sells. I love it.”


EuroDOCSIS 3.1

EuroDOCSIS is a European variant of the DOCSIS standard, which was developed by CableLabs and facilitates superfast internet via coax cable. The current version allows us to offer internet access at speeds of up to 120 Mbps. CableLabs is heavily involved in the development of the next version, DOCSIS 3.1, which in time will accommodate realistic internet download speeds of 1 Gbps and upload speeds of 100 Mbps.
