During its recent 2016 Winter Conference, CableLabs unveiled a Full Duplex DOCSIS technology that aims for multi-gigabit rates. The breakthrough increase in the upstream speeds for DOCSIS delivered broadband service is achieved by applying emerging techniques from wireless networks to the cable infrastructure.
CableLabs said this new approach significantly increases upstream data capacity in order to enable symmetric multi-Gigabit broadband data services for consumers and the enterprise. These developments are expected to yield DOCSIS 3.1 network performance of up to 10 Gbps symmetrical on 1 GHz HFC networks, with the potential for even higher performance by utilizing spectrum that is currently available for future expansion above 1 GHz.
