Model Finds Optimal Fiber Optic Network Connections 10,000 Times More Quickly

Designers of fiber-optic networks will be able to find the most efficient way to connect phones and computers that are in different places in just a few seconds by using a new model developed by researchers at North Carolina State University (NCSU).

The mathematical model identifies the exact optimal routes and wavelengths of light to use, creating a large graph of all paths through a ring that ensures information gets to where it needs to go, and displays where those paths overlap. The graph is broken into smaller units, with each unit consisting of the paths in a ring that do not overlap. As a result, the paths can use the same wavelengths of light.

In addition, by breaking all of the potential paths down into smaller groups, the model is able to identify the optimal path and wavelength between two points much more efficiently than previous techniques. "This will significantly shorten the cycle of feedback and re-design for existing rings," says NCSU professor George Rouskas. "It also means that the ring design work can be done using fewer computer resources, which makes it less expensive."
