ZTE Partners for EPON TV

ZTE Corp. (Shenzhen: 000063; Hong Kong: 0763) and Comcast Corp. (Nasdaq: CMCSA, CMCSK)-backed silicon startup BroadLogic Network Technologies Inc. have jointly developed a way for cable operators to deliver on-demand and broadcast video services to high-rise buildings and other densely populated areas that are connected to EPON networks.

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.

As I understand it, the combo will let MSOs deliver video over EPON networks but, thanks to Broadlogic's help, still use traditional RF devices because the incoming signal gets converted at the side of the building into a format that QAM-based digital set-tops can handle. Plus they, the service providers, will want to still use the legacy coax in those buildings. JB

re: ZTE Partners for EPON TV

What's the benefit to put these two piece together ?


OLT have it's migration path, Edge-COM in a different area. they are two different thing. why bother to put it togther, share the power ?
