Huawei unveils 25 Gbps, 3 GHz DOCSIS 3.1 prototype

Huawei has demonstrated a DOCSIS 3.1 prototype that generates downstream speeds of 25 Gbps while upping the usable spectrum to 3 GHz. 

The Shenzhen-based technology company said it actually demonstrated the prototype three weeks ago at the SCTE CableTec Expo in Philadelphia. It then issued a press release last week. 

Commercial DOCSIS 3.1 deployments are still in the early phase, with most of them based on 1.2 GHz spectrum. With multi-channel bonding and orthogonal frequency division multiplexing (OFDM), that scheme enables downstream speeds of up to 10 Gbps.

For its part, Huawei said it has developed technologies that address issues brought on by large attenuation, slow and severe data distortion, and allow spectrum to be increased to 3 GHz. 

"Huawei, relying on accumulated ultra-bandwidth technologies and the integrated platform that supports multi-media Gigabit access, has constantly been making innovations in coaxial cable technologies, said Jeff Wang, president of Huawei's Access Network Product Line, in a statement. “The release of the 25G DOCSIS 3.1 prototype will surely increase MSOs' confidence in building gigabit networks with existing coaxial cables.”

In June, Huawei introduced what it billed as the broadband industry's first 10 Gbps hybrid fiber coaxial (HFC) access platform.

Making the introduction at ANGA COM 2016 in Germany, Huawei said its large capacity solution supports 10 Gbps DOCSIS 3.1 in cable and 10 Gbps PON in fiber. 

The vendor claimed the platform can save operators 70 percent more space in their headend, while improving performance by 30 percent over coaxial. 

The HFC access platform includes a large-capacity optical line terminator (OTL) for optical aggregators, a high-density 10G PON interface board, DOCSIS 3.1-based D-CCAP, 10G POIN ONT and unified network management system.
