Comcast Reaches 10G Technical Milestone Delivering 1.25 Gig Symmetrical Speeds in Trial Over a Live, All-Digital HFC Network - Seite 2

In 2015, Comcast was the first ISP to deliver gigabit-class service using DOCSIS 3.1 technology, and in 2018, the company became the nation’s largest provider of gigabit speeds using that technology.

The trial also represents an important milestone on the path to deliver on the promise of the industry’s 10G platform, which aims to eventually enable 10-gigabit-per-second speeds and beyond by leveraging continuing advances in DOCSIS and other key network technologies. Comcast is engaged in the 10G initiative along with NCTA, CableLabs and SCTE, as well as operators from around the world. In addition, Comcast and Charter Communications have worked closely to align on their approaches to 10G and are driving technology standards and architectures to benefit the industry. The latest advancements in 10G technology will be on full display next week at SCTE EXPO.

“We’re excited to move these incredible 10G technologies from the laboratory to the living room,” said Elad Nafshi, Senior Vice President of Next-Generation Access Technologies at Comcast Cable. “We’ve been inspired by the work our global technical community has done to advance the technologies that made this performance possible and are proud to begin the process of delivering those benefits to customers.”

The trial was made possible not by a single technological innovation, but rather by a series of interrelated technologies that Comcast continues to test and deploy in its network, all powered by a DAA ecosystem. These include our increasingly virtualized, cloud-based network model, a vCMTS; modern “Remote PHY” optical nodes that provide greater speed and flexibility; and the ongoing effort to extend fiber further into neighborhoods.

In the coming weeks, Comcast will expand the trial to more homes as we continue to test the performance of the service under multiple different home and network environments.
