UK Research Aims For 100x Speedup In Fiber-Based Broadband 180
Mark.JUK writes "The UK governments Minister for Science, David Willetts, has awarded £7.2 million to help support the University of Southampton's newly rebuilt Optoelectronics Research Centre (ORC) and the development ('Photonics HyperHighway') of new technologies that would be capable of making broadband internet access over fibre optic cables 100 times faster than today."

As of today, the fastest fiber NICs run at 100 Gbps (not a typo). I'm pretty sure the big Network Equipment Manufacturers (Cisco, Juniper, Broadcom et al.) are investing more than £7.2M in R&D to develop this too, so I'm kind of mixed. Also, most Carriers and ISP core networks still run on aggregated 10 Gbps, sometimes 40 Gbps, and none (as far as I know) run at 100 Gbps. So the "capacity crunch" they talk about is mostly due to a lack of investment from the companies...
I think L3 runs 100Gbps. The MLXe has 100Gbps line cards and aggregated 40Gbps is quite common on the backhaul networks. As most people have said, it's not the backhaul that's the issue, it's the last mile. Research into higher speeds over copper twinax is what we really need. I can't see any telco putting fibre to the door unless they are forced to, or it's a new build. Copper is going to be here for a very longtime, so let's get that sorted soon.
