Imagine a router capable of directing 10 times the traffic of today's Internet in one second. That's the promise of Lucent Technologies Inc.'s all-optical router based on the WaveStar LambdaRouter invented at Bell Labs. The approach uses a series of microscopic mirrors to instantly direct and route optical signals from fiber to fiber in the network, without first converting them to electrical form (as is done today).
Lucent says that will save service providers up to 25% in operational costs and enable them to direct network traffic 16 times faster than electrical switches.
