For the first time ever, cable technologists are pursuing their dream of delivering symmetrical, multi-gigabit speeds over HFC lines. Known as Full Duplex DOCSIS, the proposed extension to the new DOCSIS 3.1 spec calls for using echo-cancellation technology to deliver speeds as high as 10 Gbps downstream and upstream over the exact same spectrum. CableLabs officials aim to craft the spec by the end of next year, enabling MSO deployments to start as early as 2018 or 2019. But Full Duplex, with its requirement for deep fiber builds, raises major technical, operational and financial issues for cable operators that must be resolved before its benefits can be reaped.

Delve into the Full Duplex DOCSIS details in this exclusive, interactive webinar with four top cable technologists, and come loaded with questions for our speakers.

From The Founder
Ngena's global 'network of networks' solves a problem that the telecom vendors promised us would never exist. That doesn't mean its new service isn't a really good idea.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
