Comcast said it has tested the industry’s first 10G modem capable of delivering multigigabit speeds into consumer homes. As the nation’s largest internet service provider, Comcast is looking to further market proprietary wireless technology in a rapidly evolving mobile streaming video ecosystem.
In the lab test, a Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem built by Broadcom delivered upload and download speeds faster than 4 gigabits per second (Gbps) powered by 10G network technology.
In addition to providing a path to multigigabit upload and download speeds at scale, 10G aims to deliver near-term benefits to customers in the form of increased reliability, performance, and lower latency.
“The great strength of our smart network design is that we are able to exceed our customers’ demands today, even as we continuously evolve to meet the needs of the future,” Charlie Herrin, president of technology, product, experience at Comcast Cable, said in a statement. “As our 10G journey continues to accelerate, customers will reap the benefits of ever-increasing security, reliability, and speed.”
The announcement is the latest in a series of 10G benchmarks from Comcast. In October 2021, the company announced a successful test of a complete 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology. That announcement followed a previous test in April 2021, of the first-ever live lab test of a 10G system-on-chip (SOC) and October 2020, of a trial delivering 1.25 gigabit-per-second (Gbps) upload and download speeds over a live production network using Network Function Virtualization (NFV) combined with the latest DOCSIS technology.
