The standard defines robust multi-gigabit optical automotive Ethernet (2.5G–50G) over multimode fiber, delivering low-latency, EMI-immune links with high bandwidth and reduced cabling weight — forming the foundation for software-defined vehicles and advanced driver-assistance systems.

Optical automotive Ethernet technology is transforming the in-vehicle network landscape, combining high-speed performance, robustness, and efficiency for future software-defined and autonomous vehicles. As automakers shift toward centralized zonal architectures and higher levels of automation, optical links are emerging as a critical enabler to meet the stringent bandwidth, flexibility, and reliability requirements of next-generation mobility.

Built on Keysight’s proven FlexDCA platform, the AE6980T integrates advanced Transmitter Distortion Figure of Merit (TDFOM)-assisted measurement capabilities. As the key metric for assessing optical signal quality, TDFOM enables predictive analysis of real-world performance and simplifies device debugging through detailed margin and eye-quality evaluations. The compliance application further enhances efficiency by automating complex test setups and generating comprehensive HTML reports for validation and engineering teams.

Key features and benefits of the nGBASE-AU Optical Automotive Ethernet Transmitter Test Solution include:

Full compliance with IEEE 802.3cz Amendment 7, 2023 and Open Alliance TC7 test house specifications.

TDFOM measurement suite (including TDFOM OMA, ER, AOP, and OAR) for industry-leading signal quality assessment.

Supported oscilloscope models: Keysight DCA-M model N1092A/N1092C, with clock recovery via Keysight N1077B.

Intuitive test automation interface on FlexDCA, enabling both conformant and developer test configurations.

Keysight ( KEYS ) collaborated closely during the development of the IEEE 802.3cz standard with KD, an optical transceiver chipset maker and leader in nGBASE-AU multigigabit optical automotive Ethernet technology. The collaboration also resulted in the final version of the TDFOM test specifications. KD’s software-based TDFOM reference receiver and signal metric analysis align with the IEEE standard specifications and integrate seamlessly into Keysight’s test equipment and in-vehicle networking systems.

David Ortiz, Chief Technology Officer of KD, stated: “Keysight's new test solutions, designed for test houses, Tier-1 suppliers, and OEMs, support the robust automotive optical communications standard IEEE 802.3cz. They represent another step forward in building a complete ecosystem that will drive the adoption of optical automotive Ethernet communications in future vehicle platform architectures.”

Thomas Goetzl, Vice President and General Manager of Keysight's ( KEYS ) Automotive & Energy Solutions, said: “Automotive Ethernet has advanced significantly, with optical fiber now delivering major advantages for enabling multigigabit in-vehicle networks. By combining our innovative test and measurement solutions with deep expertise in optical measurement technologies, we help customers develop and validate reliable high-speed connectivity for the next generation of vehicles.”

Keysight ( KEYS ) is redefining the future of automotive connectivity with solutions that set new benchmarks for performance and reliability. Driven by the transformative potential of optical automotive Ethernet, Keysight ( KEYS ) is helping lead the industry into a smarter, safer, and fully connected era of mobility.
