Collaboration to Advance Multigigabit Optical Automotive Ethernet Testing
KD, a fabless semiconductor company, is pleased to announce a landmark agreement with Keysight Technologies to partner on optical parameters measurement including TDFOM based on the IEEE Std 802.3cz physical layer test standard.
The Transmitter Distortion Figure of Merit (TDFOM) is a key metric for assessing the quality of multigigabit optical signals transmitted over glass optical fiber. As defined in the IEEE Std 802.3cz, TDFOM is measured after a reference receiver, which emulates a representative integrated circuit (IC) implementation and ensures the interoperability of transmitters in terms of signal integrity, valid to be received by a compliant receiver. Furthermore, TDFOM is critical for calibrating reference transmitters, enabling precise compliance assessment of optical receivers.
The TDFOM measures the transmitted optical signal ability to meet the required system Bit Error Rate (BER) after passing through a worst-case optical channel and a reference receiver, evaluated using an optical-to-electrical converter (O/E) and an oscilloscope. Keysight and KD have been in close collaboration during the development of the IEEE 802.3cz standard to create the final version of the TDFOM. KD has developed a software-based reference receiver and signal metric analysis, aligned with the IEEE Std 802.3cz specifications.
„With this agreement, we make a big step in providing to OEMs and Tier-1 companies with the necessary means to test the quality of developments that incorporate optical communications according to the IEEE Std 802.3cz. Keysight and KD have collaborated in IEEE 802.3 to define the tests and metrics that ensure the new Ethernet communications standard meets the quality requirements demanded by the automotive industry,“ stated Ruben Perez-Aranda, KD“s CTO and co-founder.
This partnership underscores KD“s and Keysight’s commitment to supporting technological innovation in the automotive sector, driving advancements in optical communication systems, and ensuring the highest standards of quality and performance.
Thomas Goetzl, Vice President and General Manager of Keysight’s Automotive & Energy Solution highlighted the importance of this agreement:
„Automotive Ethernet technologies have evolved and now derive significant benefits from optical fiber technologies for enabling multigigabit in-vehicle networking.
