This device can use up to 32 wavelengths of light. The Metro 1500 is intended for large corporations or regional telephone companies that want to move large amounts of data, voice and video quickly over distributed networks, Farnsworth says. LuxN Inc. of Sunnyvale, Calif., is marketing a product called ColorSIM that uses a new technique to measure the quality of service on an optical link. These agreements are guarantees of service quality based on measurements such as the maximum number of dropped packages or the number of error-free seconds per month. LuxN takes a different tack that involves the peculiarities of how light pulses really travel over a fiber optic cable, Strudwick says.
Data is moved digitally, but in practice the pulses are really like an analog signal.
We take that signal coming out of the fiber, and, after it is converted to electrical impulses, look at the shape and characteristics of the signal through real-time signal processing. What you get is a continuous measurement of the quality of the light signal coming out of the fiber. To the best of my knowledge, nobody is doing anything like this right now. Inc.
