Latest company news about YOFC Global Promotes Intelligent Automotive Fiber Optic Communication Solution

Currently, the global automotive industry is undergoing the most profound transformation in a century, with the rapid development of automotive electrification and intelligence technology. The large number of electronic components and ultra large capacity batteries make the design of electromagnetic shielding for the entire vehicle increasingly complex. At the same time, the extensive use of in car cameras, various radars, in car artificial intelligence and other applications will increase the in car data communication speed to 10, 25, 50Gbps or even higher. Therefore, the traditional carrier of automotive communication - copper wire, can no longer support the demand for high-speed communication in vehicles. Quartz fiber optic, which has multiple advantages such as high bandwidth, low loss, no crosstalk, no electromagnetic interference, small size, low weight, etc., has begun to enter the automotive field and is expected to usher in a new round of "light advance and copper retreat" in the automotive industry.


To further develop the electrification and intelligence of automobiles, YOFC Fiber Optic Cable Co., Ltd. (hereinafter referred to as "YOFC") With 35 years of technological accumulation in the field of fiber optic transmission, we have launched intelligent automotive fiber optic communication solutions. This scheme is based on the vehicle Ethernet architecture and the vehicle grade quartz fiber optic communication standard IEEE802.3CZ. The vehicle's own electrical signals are converted into optical signals through photoelectric conversion modules. The signal transmission is carried out using the vehicle optical connector and the vehicle quartz multimode fiber optic cable as the physical layer transmission medium. It has the characteristics of high speed, high reliability, low loss, anti electromagnetic interference, easy installation, and lightweight, This plan will significantly improve the electrification and intelligence level of vehicles, enhance their safety and reliability, and reduce vehicle energy consumption and maintenance costs.

1. High speed:


The YOFC Intelligent Automotive Fiber Optic Communication Solution retains the high transmission rate characteristics of fiber optic communication. In the vehicle Ethernet architecture, the point-to-point transmission rate supports 2.5, 5, 10, 25 to 50Gbit/s, and its bandwidth is much higher than copper wire or coaxial cable, which can support higher speed data transmission and meet the communication needs of vehicle systems for large data volume and high real-time performance.


2. High reliability


YOFC Intelligent Automotive Fiber Optic Communication Solution can meet all the reliability standards of current copper cable communication solutions and adapt to various harsh environments that may be encountered during vehicle operation.

3. Low loss


The transmission signal loss of optical cables in YOFC Intelligent Automotive Fiber Optic Communication Solution is extremely low, with a loss of less than 0.004dB per meter. Generally speaking, as the frequency of the signal increases, the loss of copper cables also increases. However, this solution overcomes this problem. In high-speed signal transmission scenarios, low loss long haul optical cables can greatly improve the communication quality over long distances in vehicles.


4. Anti electromagnetic interference


The transmission core of YOFC optical cable is mainly made of quartz material, which naturally has electrical insulation properties; Unlike electromagnetic signals, signals in optical cables are transmitted in the form of light waves and are not affected by electromagnetic interference. Therefore, YOFC Intelligent Automotive Fiber Optic Communication Solution has extremely strong anti-interference ability, which can ensure stable transmission in complex electromagnetic environments and is suitable for various in vehicle communication scenarios that require high anti-interference performance.


5. Easy to install


YOFC optical cable has extremely strong mechanical properties, is bendable, has high compression resistance, and is suitable for wiring in narrow spaces inside vehicles. At the same time, when using YOFC Intelligent Automotive Fiber Optic Communication Solution for wiring, there is no need to consider electromagnetic interference and grounding settings, which will provide vehicle wiring with much more convenience than traditional copper cables.


6. Lightweight


The weight of YOFC Fiber Optic Cable is less than 30% of STP, and its lightweight characteristics can help reduce the weight of the entire vehicle, reduce operating costs, and promote the development of low-carbon and environmental protection strategies in the automotive industry.
