I promise that, after today, I will stop geeking out about the Olympics. Yesterday I posted about the 3D tie-ins, but today’s focus is on the massive fiber network that serves as the backbone to the event. The 2010 Winter Olympics is a showcase of the AV/IT and social media convergence that is a reality, not a possibility.

According to Network World Canada , “Bell Canada Enterprises Inc. says it has laid 5,000 kilometres (approx. 3,280 feet) of fibre at the Olympics venues in Vancouver and Whistler, providing 20 Gigabits per second (Gbps) of throughput for video feeds, photo file transfers and phone conversations.”

This fiber network is expected to carry every audio and video stream from every venue and every broadcaster. Amazing…. In this interview, Avaya’s chief network architect talks about the two years spent building the Olympic’s first all-IP network that will serve about 35,000 people.

Avaya and Bell Canada aren’t the only tech companies making a splash. Here’s a short slideshow by Network World that features some of the tech behind the Olympics.

Google has also sent their Street View team to map the villages at the base of the mountain. The Olympic Village also features a digital graffiti wall by Tangible interaction, a Vancouver-based company that specializes in interactive sensory experiences.

And, unlike at the 2008 Summer Games in Beijing, athletes and spectators will have full and free access to social media tools like Twitter and Facebook. Twitter has a list of verified Olympians and the IOC has created a Facebook fan page.
