Study on Optical Fiber Communication in Vehicle

Abstract

We designed an in-vehicle communication system using wavelength division multiplexing and investigated its characteristics under various environments. Since a single optical fiber can communicate multiple wavelengths of light, it is assumed that this will lead to a reduction in the number and weight of cables required for communication compared to conventional coaxial cables. As a result, vehicle maintenance and fuel efficiency were improved. Using data from coaxial cables as a reference, the transmission characteristics of single-mode fiber (SMF), the wavelength division multiplexing (WDM) systems, and the transmission characteristics of optical fibers were measured and compared in an in-vehicle environment.
