Wellbrock, director of backbone network design, expects those build-outs to start by 2012, possibly earlier. But here's the catch: "100 Gbit/s" here implies coherent detection, which in turn means Verizon Business won't use any optically based dispersion compensation. Dispersion will be corrected using the receiver's electronics.
That's likely to be the norm for long-haul 100-Gbit/s links, anyway. But it means that Verizon will insist on coherent detection for 40-Gbit/s traffic, too, on those new fiber routes.
He reprised that talk in early February and brought up the topic again a few weeks ago, at the Ethernet Technology Summit in San Jose, Calif.
