10GBASE-AU Optical Ethernet Debuts at IAA 2026

KD Demonstrates 10GBASE-AU Optical Ethernet at IAA Transportation 2026

On September 22, KD announced that it had presented a real implementation of 10GBASE-AU Automotive Optical Ethernet at IAA Transportation 2026. The demonstration featured Leopard Imaging's LI-VENUS-ISX031-BASE-AU automotive camera, integrating KD's KD7251 optical transceiver with a hybrid cable and connector system designed and developed by Corning. The implementation provides a practical example of how optical connectivity can be incorporated into automotive camera systems, replacing a conventional copper interface with an optical link designed for high-speed data transmission. The demonstration focused on capabilities relevant to automotive applications that require substantial bandwidth and reliable connectivity.

Optical Link Replaces Conventional Copper Interface

The Leopard Imaging camera replaces a conventional copper interface with an IEEE 802.3cz-compliant 10GBASE-AU optical link. Within the demonstrated system, KD's KD7251 optical transceiver enables data transmission at speeds of up to 10 Gb/s. This implementation connects the camera through an optical architecture rather than relying on the traditional copper connection, demonstrating how automotive Ethernet can be adapted for demanding data-transfer requirements. The use of an optical link also forms the basis for several connectivity characteristics highlighted in the demonstration, including high bandwidth, resistance to electromagnetic interference, reduced cable weight, and extended transmission distances.

Leopard Imaging Camera Demonstrates Automotive Application

The LI-VENUS-ISX031-BASE-AU camera from Leopard Imaging provides the automotive application for the demonstrated optical Ethernet implementation. By integrating the KD7251 optical transceiver and the hybrid cable and connector system developed by Corning, the camera illustrates how optical connectivity can be incorporated directly into a high-data-rate automotive sensing system. The implementation is particularly relevant to cameras and sensors that generate substantial data and require dependable links between components. The demonstration therefore connects the optical Ethernet technology with practical automotive sensing hardware rather than presenting the technology only as a standalone connectivity concept.

Optical Connectivity Targets High-Data-Rate Automotive Systems

The demonstrated optical solution offers several characteristics that can be relevant to demanding automotive applications. Its data transmission capability reaches up to 10 Gb/s, while the optical connection provides immunity to electromagnetic interference and can support link distances of up to 40 meters. Reduced cable weight is another potential benefit compared with conventional copper connectivity. These characteristics are particularly applicable to cameras, sensors, and other systems that require high data rates. The combination of bandwidth, interference immunity, lower cable weight, and transmission distance demonstrates why optical connectivity can be considered for automotive architectures with increasing data-transfer requirements.

Relevance to ADAS and Autonomous Driving

The characteristics demonstrated by the optical Ethernet implementation are especially relevant to advanced driver assistance systems and autonomous driving applications, where cameras and sensors can require high-bandwidth connections. The 10GBASE-AU link provides a transmission path capable of handling data at up to 10 Gb/s, while its immunity to electromagnetic interference addresses a connectivity characteristic important to automotive environments. The potential for link distances of up to 40 meters and reduced cable weight also supports the requirements of distributed sensing architectures. The demonstration by Corning, KD, and Leopard Imaging therefore shows how optical connectivity can be applied to automotive sensing systems requiring high-speed data transfer.

Industry Impact & Outlook

KD's demonstrated implementation indicates how automotive optical Ethernet could support the connectivity requirements of increasingly data-intensive camera and sensor systems, particularly in ADAS and autonomous driving architectures. The combination of 10 Gb/s transmission, electromagnetic interference immunity, reduced cable weight, and up to 40-meter link distances addresses several requirements associated with distributing high-data-rate components across a vehicle. The practical integration of the KD7251 transceiver, Leopard Imaging camera, and Corning-developed hybrid cable and connector system also provides a concrete example of how optical connectivity can move into automotive hardware implementations. Further adoption will depend on how such architectures are incorporated into future vehicle systems and component designs.
