| Summary: | Firstly, the trends of vehicle intelligence and connectivity were analyzed, along with the new requirements and challenges imposed on in-vehicle communication by the evolution of automotive electrical electronic architecture (EEA). It was pointed out that vehicular optical communication would undergo a development process similar to the “fiber replacing copper” transition in telecom fixed access networks, shifting from “narrowband communication + copper wiring harnesses” to “broadband communication + optical fiber harnesses”. And then, a technical roadmap and standardization proposal for vehicular passive optical network (V-PON) were presented. To address the demands of in-vehicle communication and the challenges posed by its unique operating environment, adaptive improvements were made for existing PON technologies, and key technical hurdles were overcome to establish the V-PON standard framework.This approach fully leverages China’s technological and industrial advantages in optical communication and PON systems, facilitating the development of core intellectual property in vehicular communication. It supports the transformation and upgrading of intelligent connected vehicles (ICV) and enhances the global competitiveness of China’s automotive and telecommunications industries. |
