ing to get 10 times the distance and 10 times the speed,” he said.
Adopting Fiber Optics Sandia began looking at fiber op-
tics early in the technology’s develop- ment because of its promise of higher bandwidth — greater communication speed — at longer distances. The labs started converting from copper in the 1980s, first installing then-emerging fiber optics in a single building and bumping that facility to Megabit speeds. “Today we’re way past that. We’re at 10 Gigabit-type rates and looking hard at 100,” Gossage said. After years of planning, Sandia
completed a formal network plan in late 2008 and sought competitive bids the following year. Sandia se-

nology began moving to desktops in 2011, and by the end of 2012, Sandia had converted more than 90 percent of bulky copper cable to a fiber optics LAN. Sandia, which will spend about $15 million on the project, needs su- perb computing capability for the problems it tackles as part of its sup- port for the mission for the National Nuclear Security Administration. “Whether it’s a materials sci-
ence problem or modeling an event, we need a lot of data and a lot of pro- cessing capability,” Gossage said. “We need to be able to see it, we need to be able to view it, we need to be able to put teams together. This is a large laboratory, deeply stocked with scien-
