Title
Diffuse-infrared broadband-communication system based on multiple optical carriers
Abstract
Known non-directed infrared systems are limited to data rates up to 100 MBit/s for point-to-point communication due to multipath dispersion and limitations of optical power. Increasing demand and new applications lead to the requirement of multi-point-to-multi-point connections at 155 MBit/s and more. These data rates can hardly be satisfied by known (single wavelength) modulation schemes for diffuse links. Therefore we investigate the application of multiple wavelength modulation schemes, WDM and WSK, and show encouraging results. These seem to offer the opportunity of an extension of transmission capacities well beyond current solutions.
