[{"type":"text","content":"\nWorld-first 10G amplifier test achieved symmetrical speeds faster than 4 Gigs\n\nTechnology paves way to deploy 10G to tens of millions of customers, over the connections already installed in their homes\n\n PHILADELPHIA--(BUSINESS WIRE)--\nComcast today announced a successful test of the final technical component necessary to deliver multi-gigabit symmetrical speeds – powered by 10G and DOCSIS 4.0 – throughout its entire network. With this test completed, Comcast will launch live trials later this year, and will begin delivering 10G-powered multi-gig symmetrical services to customers before the end of 2023.\nThis press release features multimedia.

The test announced today at SCTE EXPO, showed the ability to deliver Full Duplex DOCSIS 4.0 (FDX) services over newly designed FDX amplifiers. FDX was originally designed for network environments without radio frequency amplifiers, so the new FDX amplifiers make it dramatically easier to extend the benefits of 10G to every customer within reach of the network.\n\nFor the test, Comcast inserted new 10G amps, built on a Broadcom-developed reference design, into a complete 10G network loop using previously tested DOCSIS 4.0 modem and network technologies. The team demonstrated download speeds of 6 gigabits-per-second (Gbps) and upload speeds of 4 Gbps across a complete six-amplifier cascade, sometimes called “N+6”. This architecture is inclusive of the vast majority of the Comcast network and is easily and quickly replicated where network environments may differ. As a result, the successful test is key to delivering 10G to all Comcast customers.\n\n“With this test, we’ve gone beyond proof of concept. We know we can use this technology to deliver multi-gigabit symmetrical services throughout our network and, in fact, we’re confident we have the potential to go even faster,” said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable. “With the key components of 10G tested and proven – and our digital, virtualized network architecture ready to support them – we turn our attention to extending the full benefit of 10G dir...
