Comcast today announced the successful test of its prototype 10G modem technology, paving the way toward a future in which home users can enjoy even more impressive broadband speeds.

Built by semiconductor giant Broadcom, the modem that Comcast tested is a Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem that is capable of delivering upload and download speeds greater than 4 Gbps, according to a press release shared by the company. This is twice the speed of the fastest internet provider in the U.S., Google Fiber, which maxes out at 2 Gbps.

“10G technology builds on the work Comcast has done over the past several years to build a smarter, more virtualized network,” the company wrote in a blurb regarding the new global industry initiative.

“In addition to providing a path to multigigabit upload and download speeds at scale, 10G updates will deliver near-term benefits to customers in the form of increased reliability, performance, and lower latency.”

Today’s announcement represents yet another milestone that Comcast has celebrated relating to its 10G technology. The company previously successfully completed a 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology in October 2021, followed by successful tests of a full duplex chip and a trial delivering 1.25 Gbps upload and download speeds in April 2021 and October 2020, respectively.
