Abstract
In this paper, we investigate the impact of optical crosstalk on our recently proposed indoor gigabit optical wireless (OW) communication system incorporating wavelength division multiplexing (WDM). A theoretical model that allows this impact to be assessed has been proposed. The analytical results are validated via experiments. We show that the power penalty due to crosstalk in our proposed indoor WDM OW system is lower compared to that in the conventional optical fiber communication systems. In addition, it is found that the power penalty due to crosstalk is lower for the higher speed system since the receiver preamplifier-induced noise dominates the noise process. Finally, the maximum err..
