“光纤上车”促进智能汽车功能升级

Core Viewpoint - The introduction of V-PON vehicle optical communication solutions by China Information Communication Technology Group's subsidiary, FiberHome Technologies, aims to address the data transmission challenges in smart vehicles, enhancing their functionality through fiber optic technology [1][2]. Group 1: Data Transmission Challenges - The increasing intelligence of connected vehicles necessitates the deployment of numerous sensors and display terminals, which significantly raises the demands for bandwidth and transmission speed within the vehicle [2]. - A single uncompressed 4K display in vehicles requires over 10G of bandwidth, and even compressed, it still needs between 2G to 4G, highlighting the inadequacy of traditional copper wiring in meeting these high demands [2]. Group 2: V-PON Optical Communication Solution - The V-PON solution utilizes passive optical network (PON) technology, commonly used in home fiber optic installations, to create a point-to-multipoint transmission architecture, connecting displays and cameras via fiber optics [2]. - This solution allows for simultaneous upstream and downstream high-speed transmission through a single cable, potentially reducing the required cable length and weight by up to 90%, aligning with the lightweight development needs of smart vehicles [2]. Group 3: Current Applications and Future Potential - Optical communication technologies have already been validated in certain scenarios, with bend-resistant optical cables passing internal tests by some automotive companies [3]. - The application of V-PON technology is expected to transform vehicles into multifunctional "embodied intelligent entities," enabling features such as personalized seat adjustments, automatic wiper adjustments based on weather, and real-time monitoring of vehicle conditions [4]. Group 4: Industry Significance - China has established a leading position in fiber access technology, achieving comprehensive autonomy in technology, chips, and standards, which supports the development of domestic automotive companies and reduces reliance on foreign technologies [5]. - The company plans to continue advancing automotive-grade optical communication technology, aiming for breakthroughs in core components like PON chips and optical cables, thereby enhancing the competitiveness of China's smart connected vehicles [5].
