100 Gbps Indoor Access and 4.8 Gbps Outdoor Point-to-Point LiFi Transmission Systems using Laser-based Light Sources
CoRR(2024)
摘要
In this paper, we demonstrate the communication capabilities of
light-fidelity (LiFi) systems based on highbrightness and high-bandwidth
integrated laser-based sources in a surface mount device (SMD) packaging
platform. The laserbased source is able to deliver 450 lumens of white light
illumination and the resultant light brightness is over 1000 cd mm2. It is
demonstrated that a wavelength division multiplexing (WDM) LiFi system with ten
parallel channels is able to deliver over 100 Gbps data rate with the
assistance of Volterra filter-based nonlinear equalisers. In addition, an
aggregated transmission data rate of 4.8 Gbps has been achieved over a link
distance of 500 m with the same type of SMD light source. This work
demonstrates the scalability of LiFi systems that employ laserbased light
sources, particularly in their capacity to enable highspeed short range, as
well as long-range data transmission.
