A 50 Gb/s transparent indoor optical wireless communications link with an integrated localization and tracking system

In this paper, we describe an optical wireless communications system that uses light from an optical fibre access point to provide transparent and bi-directional optical links to nomadic terminals. Full localization and tracking is implemented, and a 50 Gb/s link is demonstrated. The link operates i...

Description
Summary:In this paper, we describe an optical wireless communications system that uses light from an optical fibre access point to provide transparent and bi-directional optical links to nomadic terminals. Full localization and tracking is implemented, and a 50 Gb/s link is demonstrated. The link operates in an indoor environment, with a ± 30° field-of-view covering a distance of up to 3 m, and a localization accuracy of 0.05° (2.5 mm pointing accuracy at 3 m) is achieved. This demonstration shows that it is feasible to use an automated system to achieve the required alignment for an ultrahigh data rate fibre-wireless-fibre link.
