The world's first home 10G modem was successfully tested: download and upload speeds exceeded 4 Gigabit!

Comcast, an American telecommunications service provider, announced today that it has successfully completed the testing of the world's first home 10Gbps 10G modem prototype in the laboratory, which can bring multi-gigabit wired broadband experience to home users.

The demodulator used in this test is based on a full-duplex DOCSIS 4.0 SoC developed by Broadcom. Combined with a 10 Gigabit network, the actual download and upload speeds exceeded 4 Gbps, or 4 Gigabits.

The tests also used a hybrid fiber-coaxial (HFC) network in an experimental DOCSIS 4.0 mode.

In October 2020, Comcast used NFV (Network Function Virtualization) and DOCSIS (Data Over Cable Service Interface Specification) to experiment with 1.25-gigabit uploads and downloads on a commercial network.

In April 2021, Comcast tested the 10G SoC in its lab for the first time.

In October 2021, Comcast successfully tested a full 10G network using a DOCSIS 4.0-based vCMTS (virtualized modem termination system).
