Targeted initially at the Chinese cable market, their work has resulted in an EPON-to-QAM gateway that combines ZTE's C300 10G optical line terminal (OLT) with a BroadLogic-made IP-to-QAM node reference design that's based on its TeraQAM chip. The Broadlogic-powered OLT will serve as a mini headend of sorts, able to convert incoming IP video traffic to QAM signals that can be read and displayed by more traditional QAM-based set-tops connected to in-building coax networks. (See BroadLogic Chip Targets Altera, Xilinx.)
BroadLogic expects trials to begin by mid-year, with commercial deployments ramping up in 2012.
Why this matters
Targeted at commercial services applications with some residential potential, the ZTE/BroadLogic combo helps cable operators deal with the challenge of delivering video services over EPON, while also giving them another tool besides Radio Frequency Over Glass (RFoG) to deliver video on fiber-to-the-premises networks.
Tying a QAM interface with an EPON ONU will also let MSOs deliver digital TV services without having to build a parallel distribution network for video. (See Cable FTTP Goes Standard.)
ZTE and BroadLogic are debuting their handiwork at this week's China Content Broadcasting Network (CCBN) show in Beijing, but the product has some potential for the U.S. market too, as more and more U.S. MSOs continue to take a shine to EPON for commercial services. In fact, CableLabs recently approved a specification that lets cable operators apply Docsis-style provisioning to EPON deployments.
For BroadLogic, which also counts Cisco Systems Inc. (Nasdaq: CSCO) as a backer, the tie-in should give it some decent deployment potential in Asia/Pacific and a new avenue to pursue in the U.S.
A BroadLogic spokeswoman tells Ligth Reading Cable that a number of unnamed U.S. cable operators have already expressed interest in the video-over-EPON product.
