The stuff of world's largest fiber optic LAN: Sandia's network by the numbers
Connecting state and local government leaders
Sandia National Laboratories' network links 265 buildings and 13,000 ports, while saving space, energy and money.
Whenever someone asks where the largest fiber-optic LAN in the world is, from now on, the correct answer is Albuquerque, NM. That may seem strange, but not considering that the network is on the campus of Sandia National Laboratories.
The Lab’s optical network offers 10 gigabit/sec speeds, with the possibility of going as fast as 100 gigabits in the near future, the lab said in a release. And for the first time, being relieved of the 100-meter cable limit of copper means that even remote areas of the sprawling campus, such as the National Solar Thermal Test Facility, which sits in a far corner of Kirtland Air Force Base, is now wired to be part of the network.
Space also is saved as the thin fiber cable gives everyone at Sandia access to LAN, phone, data and video services. Most of the bulky infrastructure and overhead racks required to serve a copper network have been eliminated.
Sandia manager Jeremy Banks in a statement put it this way: Where a conventional LAN serving 900 customers requires a space the size of three double ovens, an optical network serving 8,000 requires only a microwave oven-sized space.
Where copper cable required Sandia to maintain and manage 600 separate switches in the field, the new optical LAN allows technicians to operate a data center inside a single building with simple, standard ports going out to all offices. The network supports the high-speed throughput needed for the lab’s work, and calculations for the National Nuclear Security Administration.
