Integration enables streamlined validation of IEEE Std 802.3cz (“nGBASE-AU”) links with industry-recognized Vector workflows
• Adds IEEE 802.3cz optical Ethernet testing capabilities to the VN5650 Ethernet interface using KD’s KD7251 transceivers.
• Leverages CANoe with Option Ethernet for simulation, analysis and automated testing of Ethernet-based systems.
• Preserves VN5650 strengths: up to 12 ports, robust housing, modular VNmodule60 slots for flexible PHY selection.
• Supports up to 10 Gbit/s optical links with nGBASE-AU PHYs.
Vector, a long-standing partner in embedded electronics development and networking in automotive, has expanded the capabilities of its VN5650 Ethernet interface to include multi-gigabit optical Ethernet testing in compliance with IEEE Std 802.3cz-2023. By integrating KD7251 optical transceivers from Spanish semiconductor company KD, the VN5650 can establish, monitor and analyze in-vehicle optical Ethernet links within existing Vector workflows. This enhancement marks a significant step toward mainstream adoption of optical Ethernet in automotive validation, leveraging tools and software already trusted by OEMs and Tier-1 suppliers.
With KD7251 devices installed, the VN5650 maintains its characteristic robustness and modularity supporting up to 12 Automotive Ethernet ports via VNmodule60 slots, while adding nGBASE-AU optical connectivity for link speeds up to 10 Gbit/s (with 2.5/5/10 Gbit/s supported by KD7251). Users continue to benefit from VN5650 features such as synchronous monitoring and fault/load generation, now extended to optical links.
The solution integrates with CANoe option Ethernet, enabling engineers to script, simulate, and verify Ethernet behavior at scale while assessing conformance to 802.3cz across representative vehicle scenarios. The existing VNmodule60 ecosystem remains fully compatible, allowing teams to tailor physical layers to each test setup without altering established workflows.
“Vector’s adoption of 802.3cz optical Ethernet within the VN5650 provides development teams a practical, test-bench-ready path to validate multi-gig links using the Vector tools that automotive already trust,” said Juan Luis Matus, Field Application Engineer Manager at KD. “It’s an important milestone in bringing high-bandwidth optical connectivity to automotive applications.”
For his part, Matthias Schwedt, Product Manager Ethernet at Vector, emphasized: “Together with KD’s seamless collaboration, we have once again demonstrated the outstanding flexibility of our VN5650 interface. As automotive systems demand higher data speeds and bandwidth, multi-gigabit Ethernet links will play a key role in enabling next-generation Advanced Driver Assistance Systems (ADAS) and Software-Defined Vehicle (SDV) architectures. With this integration, we are ready to support also optical multi-gigabit Ethernet testing across all scenarios – from complex CANoe-based simulations to basic media conversion at the hardware level.”
This joint effort delivers cutting-edge testing capabilities to the automotive industry, supporting the deployment of scalable, high-bandwidth solutions essential for next-generation vehicle architectures.
