Zayo's appetites get bigger every year, but yesterday's expansion announcement may be its most aggressive organic buildout yet. The fiber operator unveiled plans to build a metro network across the San Diego metro area, and we're not talking about a starter ring or two here. When complete, Zayo's San Diego buildout will cover some 400 route miles.
The metro network will cover not only downtown San Diego, but will extend as far north as Oceanside and Escondido, and of course south along the border with Tijuana. The map on the left is cribbed from Zayo's fiber maps - pink representing planned routes. When complete, Zayo will be leasing both lit capacity and dark fiber in the city, which has historically not had as many metro alternatives as the main internet hubs in and around Los Angeles and the San Francisco Bay Area.
Zayo has been expanding the Los Angeles footprint it picked up from Fibernet Telecom Group a couple years back, transforming it into a larger business as they have for so many of their other acquired assets. This buildout, however, doesn't stem from any previous acquisition, although 360Networks does have a few route miles in the city that will contribute a bit when that deal finally closes. But this is largely a greenfield entry for Zayo, an opportunity to build out some unique fiber assets in a fairly underserved major metro area.
