We wrote about Full Duplex DOCSIS® technology a few weeks back prior to the SCTE event in Philadelphia. Along with Remote PHY, virtual CMTS, video security, and virtual video processing, it was one of the hottest topics in our booth.


Why is it getting so much attention? Because cable visionaries are pursuing the goal of delivering symmetrical, multi-gigabit speeds over HFC. The proposed extension to the latest DOCSIS 3.1 specification calls for using the echo-cancellation technology Cisco contributed to the industry to deliver speeds as high as 10 Gbps downstream and upstream over the exact same spectrum. CableLabs officials aim to deliver the specification by the end of next year, enabling MSO deployments to start as early as 2018 or 2019. However, Full Duplex DOCSIS®, with its requirement for deep fiber builds, raises some major technical, operational and financial issues for cable operators that must be addressed before its benefits can be reaped.

Join Cisco Fellow John Chapman at a webinar with our industry colleagues at Heavy Reading, Cox and Comcast on Friday November 18 11am New York time / 4p.m. London time.
