While we are fully sympathetic with a focus on wireless in the access network, we have for long been advocates of bringing optical fiber as close as possible to the user and for moving from point-to-point or ring architectures in current fiber networks to mesh architectures. In this context, reports of a breakthrough in optical communication makes us happy. Of course, we understand it takes a little while to go from the pages of Science to reducing repeaters in actual optical fiber cables. One way to understand the challenge of sending data through fiber-optic circuits is to imagine a person shouting to someone else down a long corridor. As the listener moves farther away, the words become fainter and more difficult to discern as they echo off the walls.
