Comcast (NASDAQ:CMCSA) says it's pulled off a successful test of technology it wants to use to deploy multi-gigabit symmetrical speeds throughout its entire broadband network.
The company had previously completed successful tests of so-called 10G network and modem technologies, including a complete network-to-home 10G loop.

Now it's set to begin live trials of multi-gig symmetrical services (upload and download) powered by 10G and the DOCSIS 4.0 standard, and says it will offer the services to customers before the end of 2023.
The most recent test demonstrated delivery of Full Duplex DOCSIS 4.0 services over newly designed FDX amplifiers that make it "dramatically easier" to deliver 10G benefits more widely.
Earlier in September, Comcast (CMCSA) announced it was launching a nationwide rollout of multi-gigabit speeds for its Internet service.
