TRUMPF, KDPOF show first 980nm multi-gigabit interconnect system for automotive
Trumpf Photonic Components and KDPOF in Spain have shown the first 980nm multi-gigabit interconnect system for automotive systems
Trumpf and KDPOF have demonstrated an 802.3cz (nGBASE-AU) 980nm automotive optical module at the European Conference for Optical Communication (ECOC) in Glasgow. Evaluation kits soon become ready for OEMs to test.
“After a long-term cooperation, it’s great to have entered the stage where we can prove to end-users the true strength of 980nm optical interconnects,” says Ralph Gudde, VP Marketing & Sales at TRUMPF Photonic Components.
Both companies pursue the goal of implementing state-of-the art optical data communication standards and solutions for the automotive industry.

The push in the automotive sector towards autonomous driving is driving the need for optical interconnects to manage the data flow. Significant progress is made with the first implementation of the new IEEE Std 802.3cz (nGBASE-AU), consisting of a transceiver that integrates electronics, photonics, and optics in a single IC component.
Automotive applications require not only a much wider range of operating temperatures, reaching from minus 40 °C up to 125 °C but also a low interconnect length of less than 40 meters. For superior robustness against wear and random failures, 980nm VCSEL was approved as the wavelength to become the new standard. Besides its performance characteristics, 980nm suits the existing OM3 fibers with low dispersion loss.
“Automotive is a very demanding industry. The IEEE Std 802.3cz standard is therefore focusing on highly reliable conditions that enable lifetimes of 15 years and more, with low cost and high-volume implementations,” says Rubén Pérez-Aranda, CTO at KDPOF.
“Having suppliers like TRUMPF in the 802.3cz working group enriched the discussion with their deep manufacturing and design knowledge of VCSEL and photodiode components, which in turn enabled the production of a serious and dependable standard. With our strategic partnership we are going one step further and are targeting optical networks to become an indispensable part of future cars,” said Pérez-Aranda.
