Copper has had a long life for data networking connections, but an all-optical data center is likely to be in the cards somewhere in the future. And it’s going to be glass, despite the temptation of other shiny toys like RF and LEDs.
Don’t get me wrong, I love copper wiring. With a little silicon magic, very good cable, and decent crimping, you can get 10 GigE connections for short runs without a lot of headaches. At longer distances, DSP processing and clever algorithms is squeezing out more speed from existing copper plant For people who already have copper in place and some certainty with cable quality, copper is great.

The Internet2 conference this week was a smashing success. Reflecting on the audience’s comments and interest in our advanced development SDN (Software-Defined Networking) infrastructure testbed leads me to elaborate on it a bit further.
LTE-Advanced Release 10 is a major enhancement of the Long Term Evolution (LTE) standard developed by the 3rd Generation Partnership Project (3GPP). This new technology is targeting peak data rates up to 1Gbps and introduces new concepts with the ultimate goal of designing a system that is drastically enhanced in both cell capacity and coverage.
I’m excited about the potential of gigabit broadband services, but I also know it is unlikely my current broadband service provider will offer these kinds of speeds within this decade or perhaps even next. If I should be so lucky to have access to gigabit speeds (heck, I would be happy with 50Mbps) in the foreseeable future, it will likely be provided through my own city government in some form of a public-private partnership.
