And Sunflower isn't the only cable party to suggest that FTTP could play a part in the evolution of the HFC network. Last fall, a leaked "strategic assessment" from CableLabs titled Cable Response Alternatives To FTTP put forth the notion that it might be more economical for MSOs to take fiber all the way to the home¡ but not until node sizes reach below 125 homes passed. Today, plenty of HFC systems still operate node sizes of 500 or 250 homes.
Another indicator that FTTP will play a role in MSO strategies, either in greenfield pockets or as a longer-term evolutionary step, is the industry's recently created "RF Over Glass" study group, helmed by Time Warner Cable engineering exec Paul Brooks. That project, according to people familiar with it, is taking a closer look at the technology to determine whether it's necessary to take things to the next level and develop industry standards that aim to develop interoperability between vendors and drive down costs.
