SUMITOMO ELECTRIC TECHNICAL REVIEW No.98

Driven by evolutions in CASE (connected, autonomous, shared & service, and electric) technology, the need for fast in-vehicle networks has increased, making in-vehicle Ethernet an attractive next-generation communication solution. To comply with the strict communication standards set by the standards organization OPEN Alliance, our focus turned to investigating 100 M Ethernet compatibility. Initial evaluation using existing CAN components revealed disparities in transmission and crosstalk characteristics of wires and connectors. Therefore, we have developed new wires and connectors, as well as terminal processing technology, CAE analysis technology, and communication characteristic evaluation technology, all of which are necessary for the development of high-speed communication components. These efforts ensured compliance with the communication standards. We view high-speed communication components as vital elements of wiring harnesses, and are committed to their ongoing development, recognizing the significance in facilitating efficient in-vehicle communication.
