Will Verizon be the lone wolf in using an RF carrier to deliver TV services over PON connections? That's the question that some industry members have me pondering after the first day at the Supercomm tradeshow.
For the last few years, questions have arisen about the best design approach for delivering TV connections on passive optical networking (PON) links. One easy option, and the one being tapped by Verizon for its broadband PON (BPON) deployments, is the use of a dedicated RF carrier for TV services. The other is to rely on IP connections to deliver TV services.
Last year, the sector was split on the topic. But, with the inevitable move to GPON coming and EPON being deployed, most Supercomm backers are turning their backs now on the RF carrier and making IPTV their delivery choice. In fact, in one interview, a PON backer told me that Verizon's approach to TV would be more "unique" than mainstream. Others questioned the distinction that using the RF carrier provides to the GPON operator
So, it looks like the tides are shifting toward an IP-based TV delivery mechanism for PON systems. Let's just hope that equipment manufacturers can counteract the packet loss problems that could hinder IPTV from being successful. But, that's a topic for another day.
