Gigabit downloads and uploads are now possible via cable, Comcast said

Comcast’s cable internet still places a high priority on download speeds, as does its gigabit-download service. 35Mbps uploads. But that may never be the case Comcast announced today “Technical milestone” that can provide Gigabit-plus downloads And upload Speed ​​over existing cable wires.

In particular, Comcast said it had “conducted a trial of providing 1.25 Gbps upload and download speeds over the live production network using Network Function Virtualization (NFV) combined with the latest Doxis technology”. Comcast installed the service at a home in Jacksonville, Florida, where “the technical team measured 1.25 Gbps upload and 1.25 Gbps download speed.”

The speed is distributed through a hybrid fiber-cable network, with the coaxial cable providing the final connection to the home. This is nothing new — Comcast has been using both fiber and cable for years, but Comcast said it has benefited from the trial company’s “ongoing effort to expand the fiber to more neighborhoods.” Typically, symmetrical gigabit speeds require a fiber-to-the-home connection. Many homes have more cable than fiber, so symmetrical gigabit technology can be implemented faster if it is not necessary to bring fiber to every building.

Comcast, the country’s largest broadband provider, did not say when the symmetrical 1.25Gbps service will go on sale. Currently, more testing is needed. “In the coming weeks, Comcast will expand the trial to more homes as we continue to test the performance of the service in different home and network environments,” the company said.

Expect a long transition

Symmetric upload and download speeds on cable networks are possible due to updates to the cable-industry standard Doxis (Duplex Data Over Cable Service Interface Specification). These types of updates can take years to reach customers. The “full duplex” version of DOCSIS, which supports 10Gbps download and upload speeds, was finalized in October 2017 and a Version: Telugu Support for 10Gbps downloads and 1Gbps uploads was released in 2013.

Comcast claims that its symmetric 1.25 Gbps trial requires “advanced architecture”, including software fiber optics, ‘remote PHY’ digital nodes and cloud-based, virtualized cable modem termination system platforms (VCTs) with VST).

Comcast already offers multi-gigabit downloads and uploads through its fiber-to-the-home service, but the all-fiber network does not extend across the company’s entire cable service area. Comcast launched the Symmetric 2 Gbps All-Fiber service in 2015 for up to $ 300 per month and a starting fee of up to $ 1,000.

Comcast said in 2018 that its 2GBPS service would be available to 18 million homes, but today it could not find any offers for 2GBPS service on the Comcast website. Comcast’s Gigabit webpage He said you should call the company to ask about getting multi-gigabit speeds.
