VLC-FBMC Enabled Optical Wireless Data Centers

The ever-growing demand for speed and bandwidth in data-centric applications necessitates innovative solutions to overcome existing bottlenecks. Traditional data centers reliant on electronic infrastructure often face limitations in speed. While the concept of optical data centers has emerged as a promising alternative, the practical implementation has been hindered by component unavailability, such as tunable wavelength converters and optical memory. Furthermore, the transition to fiber optic technology has not fully addressed issues like heat dissipation associated with copper cables. To address these challenges, the utilization of visible light communication (VLC) within an optical wireless medium has been proposed, aiming to reduce cabling complexities and mitigate heat generation. This paper presents a comprehensive design and analysis of a VLC-enabled optical wireless data center, leveraging Filter Bank Multicarrier (FBMC) modulation. Key considerations including peak-to-average power ratio, bit error rate and error vector magnitude are thoroughly examined, accompanied by the derivation of relevant mathematical models and presentation of simulation results. Through the integration of VLC-FBMC technology, this research contributes to the advancement of efficient and high-speed data center architectures, promising enhanced performance and scalability for future data-intensive applications.
