Optical Tx tests ensure robust in-vehicle networks
Keysight’s AE6980T Optical Automotive Ethernet Transmitter Test Software qualifies optical transmitters in next-gen nGBASE-AU PHYs for IEEE 802.3cz compliance. The standard defines optical automotive Ethernet (2.5–50 Gbps) over multimode fiber, providing low-latency, EMI-resistant links with high bandwidth, and lighter cabling. Keysight’s platform helps enable faster, more reliable in-vehicle networks for software-defined and autonomous vehicles.
Paired with Keysight’s DCA-M sampling oscilloscope and FlexDCA software, the AE6980T offers Transmitter Distortion Figure of Merit (TDFOM) and TDFOM-assisted measurements, essential for evaluating optical signal quality. Device debugging is simplified through detailed margin and eye-quality evaluations. The compliance application also automates complex test setups and generates HTML reports showing how devices pass or fail against defined limits.
AE6980T software provides full compliance with IEEE 802.3cz-2023, Amendment 7, and Open Alliance TC7 test house specifications. It currently supports 10-Gbps data rates, with 25 Gbps planned for the future.
