Würth Elektronik, manufacturer of electronic and electromechanical components, has entered into a technology partnership with Spanish semiconductor developer KDPOF. The first project in which Würth Elektronik is supporting KDPOF is advancing multi-gigabit Ethernet over fiber optics in the automotive sector.

In the context of the partnership. Würth is contributing its expertise in EMC-safe circuit layouts and supplying the appropriate power magnetics and EMC components. In order to meet the needs of future connected and automated vehicles, KDPOF’s next-generation automotive Ethernet provides high-speed links up to 100 Gb/s over glass optical fibers (GOF). Instead of multiple port components, the new solution delivers a single-component, complete automotive multi-gigabit system. Optical Ethernet connectivity solves vehicles’ challenges and electrical interference thanks to its unbeatable electromagnetic compatibility, reliability, and low cost, the companies promise.

The new connector systems are very small, light-weight, and inexpensive compared to previous ones. With cost-down and consistency in focus, optics, fibers, connectors, and electronics already developed for nGBASE-SR are leveraged. Further specifications include 980 nm VCSEL (Vertical-Cavity Surface-Emitting Laser), multimode OM3 fiber, and connectors. Applications comprise display connectivity, sensor-fusion backbone, and ADAS sensors, such as cameras, radar, and lidar.

KDPOF will showcase its solution at the Würth Elektronik booth (Hall 2, Booth 110) at Embedded World in Nuremberg, Germany.
