Maxing out the Cable HFC Network

Tuesday, October 17, 2023 @ 7:30AM - 9:00AM

Moderated by: Jaimie Lenderman
Sponsored by: Precision Optical and Applied Optoelectronics


Facing ever-mounting competition from all-fiber and wireless providers, cable operators are increasingly upgrading their hybrid fiber-coax (HFC) networks with a slew of next-gen technologies as they seek to make the most of their legacy plant. The roster of new technologies includes DOCSIS 4.0, Distributed Access Architecture (DAA), spectrum mid-splits and high-splits, network virtualization, artificial intelligence (AI) network automation and even the latest versions of PON. 

But this transformation to next-gen networks is no simple task as cable technologists grapple with such major challenges as network reliability, scalability and powering issues, along with equipment replacement issues and the sheer cost of the massive plant upgrades. How can operators and their tech partners overcome these hurdles? What upgrade strategies and techniques are they developing and deploying? Where are they seeing the biggest bang for the buck so far? What’s the timeline they are pursuing?
