Countdown's on for EPON Protocol Over Coax

A group of engineers that's studying the notion of running EPON signals over hybrid fiber/coax (HFC) networks hopes to gain approval for their project from the Institute of Electrical and Electronics Engineers Inc. (IEEE) this summer.

The near-term goal is to obtain authorization for the project, a budding IEEE standards effort called EPON Protocol Over Coax (EPoC), by July, says Study Group Chairman Howard Frazier, who's also senior technical director at Broadcom Corp. (Nasdaq: BRCM). It's envisioned that cable will use EPoC initially to offer high-capacity services to business customers. (See Why Cable Needs EPON Over Coax and EPON-Over-Coax Starts Its Standards Journey .)

The EPoC working group, formed late last year, will need that stamp before it can start the standard-writing process. In the meantime, it's made some headway on the assembly and adoption of several overarching objectives that the standard will try to nail down. What was agreed upon at the group's meeting in mid-March in Waikoloa, Hawaii, was done so unanimously. [Ed. note: And we surmise that the choice of venue didn't draw too many complaints, either.]

Most of the approved objectives sound like common sense at this point. A big one is to target a physical specification that will let MSOs operate EPON protocol on HFC, and ensure the ability to run asymmetric and symmetric bandwidths. EPoC intends to use the existing Ethernet MAC and maintain compatibility with 1G EPON and 10G EPON, making changes "only when absolutely necessary," Frazier notes.

Because cable's not in the business of doing forklift upgrades, another objective is to have EPoC signals coexist with legacy cable services (i.e. analog and digital TV, set-top box control channels, Docsis data) since it's expected that all of those services will run on the same swath of cable spectrum. Also, EPoC will give operators bandwidth flexibility in this area rather than specifically telling MSOs how and where to carve out bandwidth for EPoC. [Ed. note: A more detailed blow-by-blow account of the meeting can be found here (PDF).] (See The Case for EPON-Over-Coax & CCAP Coexistence.)

"We want this to be a worldwide standard, so we probably can't define a worldwide band plan," Frazier says. "We know that EPON works. We know that Docsis works. Now we're trying to run EPON over a plant that supports Docsis."

He acknowledges that the group "is really at the forming stage," noting that the vendors, service providers and chipmakers involved are learning how to listen and talk to each other and drive toward what's mutually beneficial. "We weren't there a couple of months ago," he adds.

The working group isn't ready to expand beyond itself yet, but Frazier says the project is "on track" to secure IEEE project approval this summer. Looking ahead, the group will hammer out more objectives at two interim meetings proposed for the week of May 14 in Minneapolis, Minn., and the week of June 6 in Beijing.

re: Countdown's on for EPON Protocol Over Coax


Well, you're definitely not the first one to suggest as much... but they're calling it that because the goal in mind is to modulate PON signals on HFC plant, so you've got fiber to the node, anyway, then coax to the premises. And cable loves its acronyms. JB

Is EPON over coax an oxymoron? Not nitpicking here, but really would like to know because my understanding is that PONs use fiber...great if someone would clarify.

re: Countdown's on for EPON Protocol Over Coax


Not too hard to imagine a new header infront of the ATM packets to get the modulation.  The real trick will be the upstream CAC function via the ingestion into the HFC along with the transmission level and link budgets.

re: Countdown's on for EPON Protocol Over Coax


Perhaps it might get clearer if the author of this article got the name right - it is EPON Protocol over Coax (EPoC) and not EPON over Coax. We will not run light over coax (kind of wonder how one would do that) but make sure that the protocol layer of EPON can be extended into coax in HFC.


For all those interested, please take a look at http://www.ieee802.org/3/epoc/...

Indeed - as the name suggests, the expectation is that we will be able to run EPON protocol (MPCP) across fibre and coax spans of HFC network, building on mature EPON industry chain. You're welcome to join the show in May if you're interested

OK, I get it (I think); so this is electronic, not photonic. Viva la difference!

Thank you, that's an important distinction to point out, Marek. We'll be sure to correct the way we spell out the acronym. JB
