On December 19, 2024, YOFC and R&D General Institute of Dongfeng Motor Group Co., Ltd. jointly announced that the intelligent vehicle fiber-optic communication solution jointly developed by the two parties on the Dongfeng Yixun eπ007 model successfully passed a 72-day road test with a total mileage of 12,000 kilometers. The success of this test marks significant progress in the practical application of in-vehicle fiber optic communication technology, which provides strong technical support for the development of intelligentization and informatization in the automotive industry.
In the real-vehicle test conducted under comprehensive road conditions in Xiangyang, YOFC's in-vehicle fiber-optic communication system showed excellent stability and high performance, and a total of 1,176 sets of test data were collected, fully confirming the reliability of the system. This achievement not only demonstrates the application potential of YOFC technology in the automotive industry, but also lays a solid foundation for the wider application of fiber optic communication technology in the vehicle environment.
The in-depth cooperation between YOFC and Dongfeng Motor advances the practical application of fiber-optic communication solutions for intelligent vehicles, and this cooperation is regarded as a milestone in promoting automobiles towards the era of intelligence and informationization. The General Research and Development Institute of Dongfeng Motor spoke highly of this cooperation, believing that the progress of in-vehicle optical fiber communication technology is of great significance for improving the performance and reliability of the autonomous driving system, reducing vehicle weight, improving energy efficiency, and promoting the standardization and normalization of in-vehicle communication technology.
YOFC's intelligent vehicle fiber optic communication solution is based on the vehicle Ethernet architecture and the vehicle-grade quartz fiber optic communication standard IEEE802.3CZ, converting electrical signals into optical signals through an optoelectronic conversion module, and transmitting the signals through a vehicle optical connector and a vehicle quartz multimode fiber optic cable as the physical layer transmission medium. With the features of high speed, high reliability, low loss, anti-electromagnetic interference, easy installation and light weight, the solution will significantly improve the electrification and intelligence of vehicles, enhance the safety and reliability of vehicles, and reduce the energy consumption and maintenance cost of vehicles.
Advantages of the YOFC smart vehicle fiber optic communication solution include:
High speed: Supporting point-to-point transmission rate from 2.5 to 50Gbit/s, meeting the communication needs of large data volume and high real-time.
High reliability: adapts to the harsh environment that may be encountered during vehicle operation, covering the reliability standard requirements of all copper communication solutions.
Low loss: the loss per meter of fiber optic cable is less than 0.004dB, which improves the quality of communication over long distances in the vehicle.
Anti-electromagnetic interference: the transmission core made of quartz material is electrically insulating, and the transmission of light waves is not affected by electromagnetic interference.
Easy to install: the fiber optic cable is bendable, high compression resistance, suitable for wiring in the narrow space inside the car, convenient wiring.
Lightweight: the weight of fiber optic cable is less than 30% of STP, which helps to reduce the weight of the whole vehicle and promote low-carbon and environmental protection.
With the successful road test of YOFC's intelligent automotive fiber optic communication solution, we expect that this technology will bring new impetus and change to the intelligent development of the automotive industry.
