Investigation of Long-Haul 4×10 Gbps Optical Wireless
Communication System
Abstract
In the previous two decades, optical wireless communication (OWC) has made significant progress and is now considered a promising candidate for long/short-transmission access in fifth-generation networks. This paper investigates and designs a 40 Gbps bi-rate high-speed OWC. Based on results from the simulation, the system can provide an OWC range of up to 78-83 km when considering shot noise, thermal noise, geometrical losses, and additional losses into account. There is an acceptable bit error rate of 10-9. The system offers faithful communication for a link attenuation of 1-1.85 dB/km over a 10 km range with a system attenuation of 1-1.85 dB/km. Furthermore, faithful transmission is improved by obtaining better eye patterns. This design also offers superior performance over traditional optical wireless communication designs in terms of data rate, maximum coverage, robustness, and ability to handle many users cost-effectively. Therefore, an OWC system will maintain a significant role as well as serve as the next rising star in the implementation of high-speed communication towards smart housing, intelligent transportation, smart cities, and intelligent society.
