Comcast Sees Year-End 2023 for Symmetrical Multi-Gigabit Deployments, according to Telecompetitor

Comcast said it has completed a successful test of newly designed full-duplex DOCSIS 4.0 (FDX) amplifiers, which according to the company, was “the final core element of the 10G ecosystem that needed to be tested to ensure 10G technology could effectively serve Comcast’s entire network.”

With the test completed, Comcast said it will launch live trials of multi-gigabit symmetrical service later this year and will begin delivering symmetrical multi-gigabit services before the end of 2023.

“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,” Comcast explains in the press release.

In the test, Comcast inserted new 10G amps into a 10G network loop using DOCSIS 4.0 modem and network technologies that had been previously tested. The company achieved speeds of 6 Gbps downstream and 4 Gbps upstream across a six-amplifier cascade.
