Intra-vehicle optical networks and its MPI mitigation

In recent years, with the emergence of autonomous driving, the automotive industry has been undergoing a profound revolution. Autonomous vehicles rely on multiple sensing devices to perceive their surroundings and depend on high-speed, reliable intra-vehicle networks (IVNs) for data transmission. As the number of sensors grows, the data rates of both uplink and downlink in the IVN have sharply increased. The fiber optics communication has emerged as a prospective solution for IVNs due to its advantages, including high transmission bandwidth, low attenuation, strong resistance to electromagnetic interference, and light weight. However, the inherently harsh vehicular environment, including wide temperature range, frequent vibrations, and high levels of contamination, poses significant challenges to the deployment of fiber optics communication in IVNs. To address these issues, novel IVN configurations and noise elimination methods have been proposed.
