1.25 Gbit/s Visible Light WDM Link based on DMT Modulation of a Single RGB LED Luminary

Abstract

We report the first Gigabit-range visible light link based on off-the-shelf RGB-type white LEDs. By application of WDM and DMT modulation an aggregate rate of 1.25 Gbit/s within the FEC 2·10−3 limit has been reached at illumination levels recommended by the lighting standard for the working environment.
