At present, the global automotive industry is undergoing the most profound transformation in the past century. The rapid development of automotive electrification and intelligent technology has led to a large number of electronic components and ultra-large capacity batteries, making the design of electromagnetic shielding for the entire vehicle more and more complex. At the same time, the extensive use of cameras inside and outside the vehicle, various radars, and on-board artificial intelligence applications has increased the data communication rate inside the vehicle 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 on-board. Quartz fiber, which has many 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 open a new round of “optical progress and copper retreat” in the automotive industry.
To further promote the development of automotive electrification and intelligence, YOFC has launched a smart automotive optical communication solution based on its 35-year accumulation of technology in the field of optical fiber transmission. The solution is based on the vehicle-mounted Ethernet architecture and the automotive-grade quartz fiber communication standard IEEE802.3CZ. It converts the vehicle’s own electrical signals into optical signals through an optoelectronic conversion module, and uses vehicle-mounted optical connectors and vehicle-mounted quartz multimode optical fiber cables as physical layer transmission media for signal transmission. It has the characteristics of high speed, high reliability, low loss, electromagnetic interference resistance, easy installation and lightweight. This solution will significantly enhance the level of vehicle electrification and intelligence, enhance vehicle safety and reliability, and reduce vehicle energy consumption and maintenance costs.
High Speed
The YOFC intelligent automotive optical communication solution retains the high transmission rate characteristics of optical communication, and supports point-to-point transmission rates of 2.5, 5, 10, 25, and up to 50Gbit/s in the automotive Ethernet architecture. Its bandwidth is much higher than copper or coaxial cables, allowing for higher-speed data transmission and meeting the communication requirements of automotive systems for large data volume and high real-time performance.
High Reliability
The YOFC intelligent automotive optical communication solution can cover all the reliability standards required by current copper cable communication solutions and adapt to various harsh environments that may be encountered during vehicle operation.
Low Loss
The transmission signal loss of the optical cable in the YOFC intelligent automotive optical communication solution is extremely low, with a loss per meter of less than 0.004dB. Generally speaking, as the frequency of the signal increases, the loss of copper cable also increases, but this solution overcomes this problem. In high-speed signal transmission scenarios, the low-loss YOFC cable can greatly improve the communication quality over longer distances in the vehicle.
Resistance to electromagnetic interference
The transmission core of YOFC optical cable is mainly made of quartz material, which naturally has electrical insulation properties. Unlike electromagnetic signals, the signals in optical cables are transmitted in the form of light waves and are not affected by electromagnetic interference. Therefore, YOFC’s intelligent automotive optical communication solution has strong anti-electromagnetic interference capabilities, ensuring stable transmission in complex electromagnetic environments, and is suitable for various in-vehicle communication scenarios that require high anti-interference performance.
Easy to Install
YOFC has strong mechanical properties, can be bent, and is highly resistant to compression, making it suitable for wiring in small spaces inside vehicles. At the same time, using YOFC’s intelligent automotive optical communication solution for wiring eliminates the need to consider electromagnetic interference and grounding settings, providing convenience for vehicle wiring that far exceeds traditional copper cables.
Lightweight
The weight of YOFC optical cable is 30% lower than that of STP, and its lightweight characteristics can help reduce the overall weight of cars and reduce vehicle costs, while promoting the development of the low-carbon and environmental protection strategy direction in the automotive industry.
