In-vehicle camera systems that utilize optical fibers are attracting attention as the next-generation high-speed, high-reliability communication infrastructure that supports autonomous driving.
🟦 10Gbps optical communication advances in-vehicle cameras
Spanish semiconductor company KDPOF has unveiled the world’s first in-vehicle vision system that enables 10Gbps communication via fiber optics. The system consists of Leopard Imaging’s high-resolution cameras and Corning’s automotive resistant optical components to improve the performance of ADAS and autonomous vehicles.
- Leopard Imaging’s camera “LI-VENUS-ISX031-BASE-AU” equipped with KDPOF’s optical transceiver “KD7251” has appeared.
- Compared to the conventional copper communication (up to 3 Gbps), the speed is up to 10 Gbps, and it has excellent low latency and noise immunity.
- Corning has developed dedicated fiber optic cables and connectors for this system that are optimized for automotive applications.
The system is suitable for applications that require real-time performance and reliability, such as ADAS (Advanced Driver Assistance Systems), autonomous driving, driver monitoring, and in-vehicle video recording.
🟦 Summary of the background and reasons for the evolution of sensing technology
In recent years, the automotive industry has been accelerating the evolution of “sensing technology” that combines advanced sensors and cameras. As a result, the amount of communication data per unit has increased dramatically, and EMI (electromagnetic interference) and bandwidth limitations have been issues with conventional copper wires.
KDPOF’s proposed 10GBASE-AU is an automotive optical communication technology that conforms to the IEEE 802.3cz standard, and provides a noise-resistant and lightweight communication path. Compared to competing twisted pair and coaxial cables, it is expected to be an option that can adapt to future high-speed and high-reliability communication needs.
🟦 Summary
KDPOF’s 10Gbps optical communication system for automotive applications enables higher definition and real-time video transmission through a technical collaboration between Leopard Imaging and Corning.
In automobiles, where video data and sensor information are flying around, it is necessary to achieve both reliability and speed of communication. The shift to optical fiber is likely to greatly improve the issue of electromagnetic noise, but since the power supply will continue to be supplied by copper wires, I feel that there is still a barrier to complete “non-metallic wiring”.
