Fiber Update: "Controlling Your Broadband Destiny"Fiber to the Home Comes of Age Despite the public illusion that a new technology takes shape suddenly and soon has revolutionary impacts, the reality is quite different. Those of us who use services like Amazon or Travelocity may be surprised to know that on-line shopping and travel services were part of the original Prodigy business plan way back in 1982. Fiber to the home is another concept that has been floating around for a long time--waiting for the alignment of customer needs, competitive pressures and sensibly priced technology solutions. With many towns--Jackson, Tennessee (see
FOCUS: Fiber Optic Communities of the United States
In our conversation, Kipfer emphasized that the primary goal of FOCUS--unlike other organizations which concentrate primarily on technology--is to help communities "take their broadband destiny in their own hands". He emphasized that does not mean that the organization is antagonistic to incumbent providers. In fact, one of the early projects Max participated in was the community of Brambleton in Virginia, where Verizon became the provider of their fiber-based services.
There are two broad models for community-based fiber--whether deployed by a developer for a new subdivision or by a government entity for a existing community. The retail model is similar to the traditional telephone and cable model: a single entity builds the infrastructure and provides services for the end user. In the wholesale model, the infrastructure is built and maintained by one entity, and the services--voice, data and video--are provided by one or more service providers who have their own relationships with the end user and pay a wholesale rate to the infrastructure provider. Some fiber projects use a mixed model. For example, Jackson Energy is building the infrastructure and providing video services; other companies provide retail telephone and data services. The UTOPIA Project The UTOPIA project is a good example of the pure wholesale model. UTOPIA is a FOCUS member and the largest community-based fiber deployment in the US.
Q: What was the biggest problem you faced? A: (from Paul) Educating people in the communities and the state. Q: How is end user pricing set? A: UTOPIA provides the infrastructure and private providers set the terms and pricing for end-users and offer the end-user services. The private providers pay UTOPIA a wholesale rate, based on a per-service, per-subscriber wholesale cost. The wholesale pricing is success-based: when the service provider gets a paying subscriber they pay a wholesale rate which becomes lower as the volume of subscribers increases.

One Approach to Fiber Implementation: DynamicCity To get a clearer view into the construction, operation and technology behind the UTOPIA project, we arranged a follow-up interview with DynamicCity, UTOPIA's primary provider. We spoke with Ben Gould, their CMO and Jeff Fishburn, CTO. Dynamic City is in the business of building, financing and operating open service provider networks. Such networks exist in many parts of the world, with Scandinavia leading the way. Gould explained that DynamicCity's networks are built on four principles:
In the course of our discussion with Gould, it became clear that "open and vendor-independent architecture" meant a specific approach to fiber deployment: Ethernet over point-to-point fiber. We wondered why their approach excluded other fiber architectures, such as passive optical networking (PON) and analog video combined with ATM or Ethernet data over fiber. We arranged a follow-up talk with Jeff Fishburn, DynamicCity's CTO, to better understand why they were so particular about the specific fiber architecture. Jeff suggested we "look at it through the eyes of a municipality." DynamicCity believes a municipality should lay down the physical infrastructure with a very long life. "A fifty-year deal is feasible. It's like when they build an airport. Our philosophy is to first design the outside plant fiber infrastructure--it's at least a twenty year investment. The electronics come later and will have a much shorter life--perhaps a five to seven year investment. We can always trade out the box to the house" as technology changes over time. Jeff said the key advantage of Ethernet over point-to-point fiber is "today there are at least half a dozen interoperable products" meeting DynamicCity's "carrier class" standard; after the phone call he sent us a slide showing 22 companies making suitable Ethernet products. With any other approach, you're tied to a specific vendor for the electronics at both ends: "If I put in the Optical Solutions PON, I can't trade out the technology in the home without also replacing the core. Our philosophy is that no vendor can own both ends of the link." Finally, we asked about the economics of an "all IP" solution over a more traditional approach using analog RF video today along with Ethernet. Jeff said "We've done the math -- looked at the CPE cost, coax cabling, IP set-top box, RF set-top box, and services. The cost of an IP-based solution is within 5% of basic RF video delivery. We're looking at competing against satellite which needs a set-top box for each TV. "IP video has crossed over: an IP set-top box is now less expensive than an RF set-top box. With Ethernet and MPLS, all tagging and marking is on the edge of the network." Finally, we asked about dedicating an Ethernet port to each subscriber home. "I've deployed OC-3 and lots of other shared facilities. It's an evolution--we're walking on a path. There's no sense to share the switch port. Today's switches cost less--a party line doesn't make sense any more. We're using single-mode fiber. We pick up two vendor's products, hook the boxes together, and the link light comes on."
