Nokia has achieved 10 Gbps symmetrical data speeds on Hybrid Fiber Coax (HFC) cable, in what it claimed was a “major breakthrough” for the industry.
The proof of concept, called XG-CABLE, means operators can use existing HFC cables to provide upstream speeds that have been unachievable previously due to limited spectrum.
Nokia Bell Labs, which has been exploring this area since 2014, tested two different scenarios.
Point-to-point coaxial drop cable using 1.2 Ghz of spectrum delivered 10 Gbps symmetric data speeds, while a point-to-multipoint coax drop approach delivered 7.5 Gbps.
Nokia said the tech could be integrated with DOSCIS 3.1.
The launch follows the vendor’s XG-FAST tech, which is aimed at boosting copper broadband and is being tested by Deutsche Telekom.
Earlier this year, TDC revealed how much cheaper cable technology is versus FTTH and G.Fast.
Federico Guillén, President of Fixed Networks, Nokia, said: "The XG-CABLE proof of concept demonstrates that providing 10 Gbps symmetrical services over HFC networks is a real possibility for operators; it is an important achievement that will define the future capabilities and ultra-broadband services cable providers are able to deliver."
Dr Robert Howald, Vice President of Network Architecture at Comcast Cable, added: “As we continue our DOCSIS 3.1 deployments this year, this development further illustrates the power and flexibility of the DOCSIS 3.1 as a tool to deliver next-generation broadband performance.”
