Dark fiber is a growing business for both private and publicly owned networks. Data transport, data centers, ILECs, and CLECs are some of the most common users. Increasingly, wireless providers are turning to dark fiber for backhaul.

A May Fierce Telecom article reports that 14 percent of Zayo's wireless backhaul services are dark fiber solutions:

"We're seeing a shift with wireless backhaul contracts to dark fiber to the tower and we're starting to see that show up as the trend over the last couple of quarters," [Chairman and CEO Dan] Caruso said … "And you see it more pronounced in the current quarter where 14 percent of our product mix for fiber to the tower is dark fiber to the tower and you see that's grown and taken on a bigger piece of the pie."

Dark fiber leases have played an important role in developing revenue for municipalities that have invested in fiber infrastructure. Dark fiber leasing can be the only option in places where state barriers limit local options.

Santa Monica, Columbia in Missouri, and Maryland's Howard County, are only a few communities that lease dark fiber to ISPs and other commercial customers. A few networks, including Metronet Zing in Indiana, offer only dark fiber services. It is worth noting that, as Santa Monica discovered, the vast majority of businesses and residents prefer and easy, affordable, and reliable lit service rather than dark fiber. But the dark fiber niche is growing.

As more customers look for the service, negotiating leases and pricing models can be challenging. Municipal networks seeking guidance can start with a 2012 report from CTC Technology & Energy, Dark Fiber Lease Considerations [PDF].

The report covers pricing models, various methods for pricing dark fiber, and offers some...

Idaho's capital has begun leasing dark fiber from Zayo Group that will allow it to consolidate a number of data centers it has located in municipal facilities across the city. This will allow Boise to better meet the internal needs of City Departments; the City is not providing access to private businesses or residents.

We tend to focus on how communities have built their own networks to achieve similar ends -- ensuring fast and reliable access to city facilities, including schools and libraries (in fact, we produced a fact sheet about it).

However, long term dark fiber leases achieve some of the same goals and are frequently a far wiser decision that purchasing lit services from existing providers, particularly the national cable or telephone companies.

According to an article covering the story in GovTech,

Rather than subscribing to a service from a local telecommunications company, dark fiber allows the City of Boise access to strands of fiber optic cable between city buildings. In-house network engineers can choose the gear that is used to light the network, while maintaining complete control of protocol, platform and bandwidth, for improved flexibility.

Fran Cantwell, an IT project manager for Boise’s Parks and Recreation Department, said that she noticed an immediate improvement using the City’s online mapping system.

“Before, staff would wait for the system to slowly paint the screen,” Cantwell said. “After the dark fiber implementation, the maps load almost instantly. This greatly increased the efficiency of teams like Community Forestry, who refer to the maps and aerial photos daily.”

The project, launched in June, took about four months to complete. Some city departments have reported a 3,000 percent increase in speed, according to Adam Reno, a Boise IT infrastructure services manager. Transmitting a 30-minute video once took two hours, but can now occur in as little as two minutes.

The article provides some details on the cost, saying the City is paying Zayo $500,000 but it does not specify the term of the lease. The City claims that it would have cost $6 million to build its own fiber network, but...
