Recent sparks of interest in passive optical networking (PON) may justify a reborn faith in this nascent market, despite the impatient cries of naysayers.

PON equipment seeks to lower the cost of access networks by extending optical bandwidth without requiring more expensive "active" components such as lasers or amplifiers (see PONs: Passive Aggression for a primer).

Last week, NEC Eluminant Technologies Inc. announced $26 million in first-round funding, the initial step toward becoming independent from its Japanese parent (see NEC Eluminant Gets $26M). Also this month, Iamba Technologies Inc. emerged from stealth mode, vowing to provide competition for other newly hatched PON startups, such as Salira Optical Network Systems Inc. (see Iamba Technologies and Salira Closes $17M Round).

PON trials have been underway at SBC Communications Inc. (NYSE: SBC) for months, and requests for proposal have been issued by other leading carriers, including Qwest Communications International Corp. (NYSE: Q). Internationally, British Telecom (BT) (NYSE: BTY), Deutsche Telekom AG (NYSE: DT), and France Telecom SA have all expressed interest.

So far, however, there are only about 30 deployments of PON technology worldwide, nearly all of them with small carriers and cable operators seeking to serve small businesses and residential subscribers.

Alcatel SA (NYSE: ALA; Paris: CGEP:PA) In trials APON
Alloptic Inc. One customer plus trials EPON
Iamba Technologies Inc. In development N/A
Marconi Corp. PLC (Nasdaq/London: MONI) Two customers plus trials APON
NEC Eluminant Technologies Inc. In trials APON

Paceon One customer plus trials APON
Quantum Bridge Communications Inc. Six customers plus trials APON
Salira Optical Network Systems Inc. In development EPON
Terawave Communications Six customers plus trials APON
Wave7 Optics Inc. In trials EPON


Still, more than $527 million has been invested in private PON companies over the last two years -- at least half of all startups have received new funding this year.

These mixed messages have fueled a growing impatience with the slow realization of PON in carrier networks. While the technology continues to boil away on broadband’s back burner, many are questioning whether the still-tiny market will ever gain its legs.

What's the holdup? Actually, there are several, sources say:

  • Standards and technologies need work. Roughly half of PON products now on the market support the Full Service Access Networks (FSAN) specifications blessed last year by the International Telecommunication Union (ITU). These are based on asynchronous transfer mode (ATM) technology, so-called ATM PON (APON), and according to many sources are limited in terms of speed and flexibility. To date, just a couple of leading companies, Quantum Bridge Communications Inc. and Terawave Communications, have achieved 622 Mbit/s both upstream and downstream on PONs.

    A new series of specs being explored by the First Mile Study Group of the Institute of Electrical and Electronics Engineers Inc. (IEEE) could support faster networks that support more users and are cheaper to deploy, proponents say. But Ethernet PON (EPON) solutions are still proprietary, and standards are far from "carrier ready." What's more, without the blessing of the ITU, it's unlikely large incumbent carriers, especially RBOCs, would be willing to risk big deployments.

    Ironically, the best-selling PON is neither APON nor EPON. Optical Solutions has 23 paying customers who've adopted its proprietary radio-frequency PON. The company recently released an APON product called the FiberPath 400, however, and says that while it has just one paying customer for the new gear, the company anticipates most of the others will adopt it in short order.

  • Carriers are slow. One observer likens getting major ILECs and RBOCs to roll out anything new such as PON to "trying to turn a battleship around in the harbor." Evidence of this can be seen in the SBC trials, which have been "rolling out" for over a year, with the vendor selection announced just this past spring. Others have been in the talking stage for years. While many carriers are considering PON, they're clearly not in any rush.

  • Carrier projects are on hold. The telecom shakeout eliminated many CLECs that were prospective PON customers. And the key prospects that remain are strapped for cash, such as the RBOCs, ILECs, and MSOs (multiservice operators, such as cable companies that are moving to offer voice, data, and video services on their existing infrastructures). This situation has cut capex expenditures and put many new technology projects on hold.

But PON supporters say the present scarcity of deployments is nothing to worry about. In a report issued this past August by Lehman Brothers, for instance, analysts Andrea B. Green and Steven D. Levy say, "We believe the PON market is currently in its infancy and can record dramatic growth over the coming years. Market studies suggest that the PON market is expected to be $100 million in 2001, growing to approximately $750 million in 2004.”

Another firm recently doubled its projections for the fiber to the home (FTTH) sector of the PON market. CIBC World Markets anticipates FTTH to comprise $455 million, or roughly 45 percent, of what it projects will be a $1 billion PON market in the year 2004. Originally, the firm had said the FTTH figure would be closer to $200 million.

CIBC analyst Alan Bezoza says PONs are slowly but surely building to something big. "The timing may be pushed out, but when it starts, this will be a big market," he asserts. He projects that by 2005, FTTH PON deployments will be a $730 million business.

Proponents say several factors make PON ascendance inevitable:

  • Present access techniques aren't cutting it. Digital subscriber line (DSL) and other access technologies don't provide what carriers need to roll out a desired mix of data, voice, and video services, PON proponents say. "DSL and cable modems don't provide enough bandwidth and can't be used to create attractive services," says Mark McDonald, VP of product marketing for the Marconi Corp. PLC (Nasdaq/London: MONI) access business. CIBC's Bezoza is more direct: "DSL doesn't offer an economical solution for broadband access."

  • Replacing copper with fiber will drive PON. For many carriers, the cost of putting in fiber or copper is similar. But the potential payback isn't. The value of fiber to support more services is being augmented by reductions in the cost of singlemode fiber and construction of PONs.

  • Carriers need PON to compete. Today's carriers are going to need PON to stay competitive, particularly in the market for residential broadband services. "On the business side, cable operators are going to start attacking the business markets with a combination of voice, data, and video services," Bezoza says. This is going to force carriers to accelerate their fiber deployments via PON.

    Vendors also say carriers will need PON to extend new services, such as storage and backup. Quantum Bridge, for instance, has just begun a program to work with SAN manufacturers on new storage network offerings via PON (see Quantum Bridge Joins SAN Vendors). "This will appeal to a huge amount of businesses that have more storage than a T1 can handle but less than required for Sonet services," says a spokesman for Quantum Bridge.

None of this will happen quickly, however. Vendors and analysts say it's going to be 2003 before the PON market truly materializes. At that time, the installation of more fiber, further development of Ethernet standards, and building demand for access bandwidth should combine to drive the market.

Right now, the vendors say they've got plenty of work to get the ball rolling -- and not just in North America. "We're working with a lot of carriers to get into their labs," says David Montanaro, chairman and CEO of NEC Eluminant. "And we're seeing definite demand, domestically and internationally. Countries where there hasn't been broadband deployment are looking at PON as a compelling way to get services going, even if there has been no copper installed." He cites projects afoot in New Zealand, China, Taiwan, Hong Kong, Singapore, and Latin America.

re: PON: The Dream Is Alive
Couple things to be clear about.

1 - If the RBOCs have to unbundle PON, it will NEVER happen.

2 - The State PUCs will not allow mass RBOC deployment until PON costs are at or very near copper costs. The cable costs the same, the equipment does not.

PON has many years to go to becoming a mainstream technology. You can assume all of these startups will go bust before it does.

re: PON: The Dream Is Alive
Do some research and look at the price of deploying a FTTH system today compared to HFC.
Copper can't compete as far as bandwidth is concerned, and the gap is closing as far as price

The PON is already becoming mainstream technology

What's the price for a cable company to extend
their HFC to the home? (I assume they would use the cheapest fiber technology as well) What are the barriers (regulatory or economic) to them doing this?

OR:

1. Hi, I'm from the sprinkler company and I'm here to install your irrigation system and plow up your lawn.

2. Hi, I'm from the cable company and I'm here to replace your cable drop and plow up your lawn.

3. Hi, I'm electrical guy and I'm here to put in a new lamp post and plow up your lawn.

The bottom line is that it happens all the time --at least in my neighborhood. For big time broadband access, dig away, pal.

re: PON: The Dream Is Alive
The idea of PON maybe a leading option today for FTTH, but it is hardly mainstream. This goes back to some relevant discussion about a month ago on the Worldwide Packet article. The barriers are not just about standards becoming finalized. It has to do with :
- when the phone guys and cable guys decide they can coexist in one same infrastructure so to benefit from fiber and the idea of true integrated service network, which will not happen any time soon
- RBOCs digging up your lawn to replace the copper (in a massive scale), which is not likely to happen. By the time that happens, someone may have figured out how to squeeze a lot more out of copper, stretch the distance, etc. Even if YOU let the guys dig up your lawn, your neighbors may not, nor your city municipality, nor PUC... Bureaucracy, is it not? So don't expect FTTH/PON to be at your home in your life time, unless you move to a new neighborhood where you know will have it. It's not just a cost and disruption issue on the RBOC/CATV's side. New housing communities are the only logical place for this. And it has to be done in a grand scale in order to benefit from the economy of scale. Digging up copper or hanging new fiber on utility poles aren't going to do it.
- Community and home builders also are not necessarily comfortable about having only fiber in the ground. Maybe some. In the end there's still your copper and HFC.
- In the example of RBOC, they'll still offer you whatever version of DSL over fiber at similar bandwidth, (who knows maybe still cap you at 128k upstream...) incremental improvement in coverage because of the above issues. So they make the bucks and everyone else still suffer. Despite the economy, new bandwidth-hogging services will continue to emerge, and what you get may still not be fast enough. Will they ever get it?

So rather than PON being mainstream any time soon, perhaps the business and technology model and strategy for anything-over-fiber have to be different but more basic?
