As you might expect, the biggest owners of fiber are the big telcos and cable companies. Consider the miles of fiber owned by the ten biggest fiber owners – I note these miles of fiber are from the end of 2017 and a few of these companies like Verizon have been building a lot of fiber since then.

You might wonder why this matters? First, Zayo is the largest company on the list who’s only business is to sell transport. All of Zayo’s fiber is revenue producing. While the companies above it on the list have a lot more fiber, a lot of that fiber is in the last mile in neighborhoods where there is not a lot of opportunity to sell access to others. The biggest independent fiber owner used to be Level 3, with 200,000 miles of revenue-producing fiber before they merged with CenturyLink.
The numbers on this chart don’t tell the whole story. Companies like Zayo also swap fiber with other networks. They may trade a pair of fibers on a route they own for a route elsewhere that they want to reach. These swapping arrangements mean the transport providers like Zayo, Cogent and Level 3 control a lot more fiber than is indicated by these numbers.
It matters because as soon as you get outside of the metropolitan areas there are not many options for fiber transport. A few years ago I helped a City look for fiber transport and the three options they found that were reasonably priced were CenturyLink, Level 3 and Zayo. If CenturyLink buys Zayo they will have purchased both competitors in this region and will effectively eliminated fiber transport competition for this community. Without that competition it’s inevitable that transport prices will rise.
I think back to the early days of competition after the Telecommunications Act of 1996. I remember working with clients in the 1990s looking for fiber transport, and there were many cases where there was only one provider willing to sell transport to a community. If the sole provider was the local telco or cable company it was likely that the cost of transport was four or five times more expensive than prices in nearby communities with more choices. When I worked with rural providers in the early 2000s, one of the first question I always asked was about the availability of transport – because lack of transport sometimes killed business plans.
Since then there has been a lot of rural fiber built by companies like statewide fiber networks and others who saw a market for rural transport. Much of the rural construction was egged on by the need to get to cellular towers.
My fear is that we’ll slide back to the bad-old-days when rural fiber was a roadblock for providing broadband. I don’t so much fear for the most rural places because those fiber networks are owned by smaller companies and they aren’t going away. I fear more for places like county seats. I worked with a city in Pennsylvania a few years ago where there was a decent number of competitors for transport – Verizon, Zayo, Level 3 and XO. Since then Verizon bought XO and CenturyLink might own the other two. That city is not going to lose transport options, but the reduction from four providers to two giant ones almost surely means higher transport costs over time.
I am intrigued that Alphabet (the parent of Google Fiber) would look at buying an extensive fiber network like Zayo. Google is one of the biggest users of bandwidth in the country due to the web traffic to Google and YouTube. Their desire for fiber might be as simple as wanting to control the fiber supply chain they use. If so, that’s almost as disconcerting as CenturyLink buying Zayo if Google wouldn’t remain as a fierce transport competitor.
