The acceleration of automotive intelligence has prompted optical communication to enter the automotive field. The rapid rise of ADAS, Internet of Vehicles (IoV), and infotainment technologies has driven an explosive growth in the number of in-vehicle electronic systems and applications. Consequently, the demand for in-vehicle data transmission has surged dramatically. Traditional in-vehicle bus technologies such as CAN, LIN, and FlexRay are limited by their transmission rates, making them incapable of handling the current high-speed data transmission requirements. Additionally, copper cables, as traditional transmission media, have caused severe electromagnetic interference (EMI) problems when widely used in the in-vehicle environment. This not only affects communication quality but also poses a threat to the stability and reliability of in-vehicle electronic systems. These traditional bus technologies also struggle to overcome such EMI challenges.

In contrast, in-vehicle optical communication technology has emerged as a focal point in the automotive communication field due to its superior data transmission capabilities, excellent resistance to electromagnetic interference, and significant advantages in saving cable space. Its robust performance offers a highly promising solution to the current challenges faced by in-vehicle communication. It also indicates that optical fiber communication technology will play a crucial role in the future development of the automotive industry. Looking ahead, it is believed that more new communication architectures and transmission formats will be introduced into the automotive domain.

Against this backdrop, the "2025 In-Vehicle Optical Communication Industry Development Forum" aims to bring together experts, scholars, and upstream and downstream manufacturers across the entire in-vehicle optical communication industry chain. The forum seeks to explore the standard system, cutting-edge technologies, innovative applications, and future development strategies of in-vehicle optical communication. It also aims to build a platform for collaboration and exchange to promote the deep integration of the automotive industry with optical communication technology, fostering the prosperity of the industrial ecosystem.
