That's not what dark fiber is. Dark fiber is dedicated fiber optic strands that are not in use and available to be leased to a customer providing their own optical equipment.
Enterprises can outsource management of the capital equipment (wavelengths) or the entire network (e.g. Ethernet). The latter is known is lit services and is much more common than dark fiber.
- bluejekyll 9y agoUnused ~= overbuilt. The leasing part was implied from the parent post.
- seanp2k2 9y agoThey could also use it for existing customer traffic, but don't, as a means to control the supply to control the price and win other political objectives.
- bogomipz 9y agoNo "unused" does not automatically imply "overbuilt." There are many companies such as Lightower that build a network of "route miles" with the sole intention of leasing fiber. This is not the same thing as selling excess capacity because of a miscalculation. http://www.lightower.com/network-map/ http://www.lightower.com/network-map/
- corndoge 9y agoThat's exactly what dark fiber is. The parent merely neglected to mention the leasing part explicitly in the first sentence.
- xadhominemx 9y ago"Overbuild" has a specific definition. It means to lay fiber within another company's footprint, not to build with excess capacity.
