  Providing high data rates is one of the big concerns in visible light
communication (VLC) systems. This paper introduces a data centre design that
use a VLC system for downlink communication. In this work, RYGB laser diodes
(LD) are used as transmitters to obtain a high modulation bandwidth. Three
types of receivers, wide field of view receiver (WFOVR), 3 branches angle
diversity receiver (ADR) and 50 pixels imaging receiver (ImR) are used to
examine delay spread and SNR. The proposed system achieved data rates up to
14.2 Gbps using simple on-off-keying (OOK) modulation.
