Signal processing for the next generation of the Internet

The Internet has experienced strong, sustained growth for many years now. And the optical communications backbone of the Web has also been expanding at a high rate. In fact, an optical equivalent of Moore’s law indicates that “capacity x distance” has been increasing by an order of magnitude every four years—faster than the original Moore’s law for integrated circuits! Despite this progress, however, recent estimates indicate that significant problems are likely to occur in the communications capacity of optical fiber within the next 10 years.
