SBC Takes a Dip Into PON

Yesterday's announcement that Alcatel SA (NYSE: ALA; Paris: CGEP:PA) won a contract with SBC Communications Inc. to deliver an optical network to a residential community has raised hopes in the bandwidth access sector.

Early indications are that the deal, which involves passive optical networking (PON) gear, may just be a flash in the pan. But it also sends some key signals for the access market.

Alcatel will install the PON-driven optical network in a new housing development in California (see Alcatel Wins SBC Broadband Deal). PON is an access technology whereby a single strand of fiber is shared among multiple users through deployment of passive optical splitters.

In what Alcatel calls a "multi-year, multi-million dollar agreement" (specifics not provided), the vendor will supply SBC with PON gear for trials in the residential portion of the Mission Bay development currently underway in San Francisco. SBC says it plans to follow the trials with commercial service during the first quarter of 2003.

But the deployment will be small, at least at first: According to the Catellus Development Corp., which is overseeing the Mission Bay project, only about 595 apartments are set to be done and occupied within 2003. The rest of the 6,000-unit residential portion of Mission Bay will roll out "over a 15- to 20-year period."

Sources say Alcatel won this award in part thanks to a longtime relationship with SBC. Alcatel supplies DSL gear and digital loop carriers to SBC, and it was an early supplier to SBC's now-defunct Project Pronto DSL trial, which reportedly was ditched last year by SBC when unbundling loomed (see Competitive Carriers Lash Out at FCC).

Other competitors, such as Quantum Bridge Communications Inc., weren't ready with residential gear when the initial SBC request went out late in 2000 or early in 2001. Marconi PLC (Nasdaq/London: MONI), which also bid, subsequently pulled out of the PON market (see Marconi to 'Streamline' Access ), although it says it will support a deal for trials at Verizon Communications Inc. (NYSE: VZ) and hold its products in abeyance until a market comes along. Paceon, which won a trial award from SBC for business PON in Texas last year, apparently didn’t have the goods SBC wanted in a residential device.

Other PON vendors say they found themselves locked out of the RFP when they requested inclusion later on.

Is the SBC/Alcatel deal yet another example of a slow-moving RBOC/PON trial set to go nowhere? No, say PON pushers. A tough bunch, used to disappointment but ever optimistic (see PON Believers Hang Tough), proponents say Alcatel's news is good, for several reasons:

  • The deal is with an ILEC. This is the first move by an ILEC (incumbent local exchange carrier) toward anything resembling a commercial service involving PON, proponents say. No matter that it's small, it's a start. "SBC could have used point-to-point or active electronics," says Tom Neel, product line manager at Alloptic Inc., which makes Ethernet-based PONs (EPONs). "It's a validation of PON architecture."

  • It's a new construction project. Many PON vendors have long held that the real opportunity for PON lies in new residential or business buildouts, where fiber isn't set to replace copper at great expense. The choice of PON for Mission Bay validates that tack.

  • It's a residential undertaking. It's significant, PON watchers say, that this high-profile ILEC trial is taking place in a residential, not a business, setting. While many companies, such as Paceon, Quantum Bridge, and NEC Eluminant Technologies Inc., insist that business PONs will build volume and competitive pricing for the larger, more slowly growing residential opportunity, others say they're just plain wrong. "That approach has been proven not to work," says Darryl Ponder, CEO of Optical Solutions Inc., another ATM PON maker and the market leader. "Right now, major independent phone companies, municipalities, and developers are putting in PONs." Waiting on the business market is a mistake, he says.

  • It's video. Alcatel makes a broadband PON according to newly defined additions to the International Telecommunication Union (ITU) standards for ATM-based PONs. These specs, known as recommendations G.983.4 and G.983.5, call for the allocation of PON bandwidth for video, either through the overlay of radio frequency signals on a separate wavelength in the PON stream, or via encapsulation of MPEG video signals in an IP stream on the PON. Alcatel claims to support both methods. Other vendors, including Quantum Bridge, say they're working on it. And EPON vendors like Alloptic say they provide both video methods easily, thanks to the larger bandwidth capabilities of Ethernet.

  • The deal helps the access market. Alcatel makes DSLAMs and other access equipment, a point that won't be lost on its competitors. This deal may tempt large vendors that have avoided developing PON technology to take another look. They may now look at it as an option in a larger access strategy. Vendors like ADC Telecommunications Inc. (Nasdaq: ADCT) may reconsider, as well as IP/DSL players like Cisco Systems Inc. (Nasdaq: CSCO) and Riverstone Networks Inc. (Nasdaq: RSTN).

    re: SBC Takes a Dip Into PON This is the same story as http://www.lightreading.com/do... but filed by SBC. It is for Alcatel's APON solution. This is a good direction for SBC since they were unable to get layer one encryption into EFM at the last meeting.

    re: SBC Takes a Dip Into PON yes, that's the press release...

    re: SBC Takes a Dip Into PON Isn't one of the biggest problems with PON is the fact that by using passive components, you don't have the operational visibility to provide adequate management of the downstream network?

    re: SBC Takes a Dip Into PON Is DSL the service SBC would offer to his housing community? I assume it is. This leads me to a question that I've been asking for years. Does DSL service require copper in a significant portion of the path to your house? When I called to get DSL service in Boston verizon told me I couldn't get the service because there was too much fiber in a loop test done from my house to the closest office.

    So the question becomes if this is DSL has DSL evolved or are there different flavors of DSL which allow for PON and how does it work?

    re: SBC Takes a Dip Into PON I've understood that in the PON world, it won't be optics brought right to your house. Rather, the ONU side of the PON equation could be a hub for VDSL or some other short reach, high speed copper interconnect. They can run 55M downstream over twisted pair, more than enough for bundled service. Fiber directly to a house is quite a ways off because the system cost is simply too high to support a consumer product. (sub-$300 in volume 10K+ for the tranceiver alone). That will be a difficult price point to break, especially considering the new standards for increasing reach from 10 to 20km will force optical vendors to use more expensive DFB lasers and more expensive receive diodes. IMHO

    > sub-$300 in volume 10K+ for the tranceiver

    It is WELL below $300 for the transceiver. One of the price things to remember is that you don't have RF amplifiers, etc. in the field like you do with HFC, or mini DLC/DSLAMs like you have with DSL. Those cost thousands, even if they are spread over a dozen or two homes that is still hundreds of extra dollars per home that is still there. Yes DSL and HFC end up with cheaper home equipment, but PON makes up for it with much cheaper nodes in the field.

    As for needing DFB lasers and more power - many deployments don't need the full 20km reach, so they can use a slightly lower power and much cheaper laser for the majority of the homes, and save the expensive ones for just those homes that are at 20km (or if you stretch the standards - beyond 20km)

    re: SBC Takes a Dip Into PON I don't know where you are getting your information from but I must disagree with your assumption.
    PON is a network topology in which there are no active components in the network. There is communication between the headend and the ONU's to provide OAM&P

    re: SBC Takes a Dip Into PON If Ms. Jander did the least bit of fact checking, she would have learned that the ITU documents she referenced (G.983.4 and .5) have nothing to do with video. G.983.4 describes a dynamic bandwidth allocation system for the upstream traffic, and G.983.5 talks about protection switching. FYI, it is G.983.3 that is related to video.

    But, perhaps I ask too much to expect the articles to be factually correct. Anyway, the messages are far more entertaining.

    re: SBC Takes a Dip Into PON SBC has been ignoring the business and economic aspects of the enterprise. It share value has declined more than 50% with almost no chance of recovery.

    SBC/Pacific Bell unnecessarily conducted tests on LMDS products. The company lost its focus and opportunities in conducting LMDS tests. Currently PON is not commercially deployable technology. So the SBC is jumping the gun by commiting to deploy the PON technology. Its develop its full attention on the DSL as this technology would improve the bottom line of SBC.

    SBC is still overstaffed and should reduce it workforce by at least by 15%.

    re: SBC Takes a Dip Into PON What do you mean by your comment
    "Currently PON is not commercially deployable technology"??
    There are indeed PON products available, if an RBOC wanted to deploy.
