TRUMPF Photonic Components has teamed up with KDPOF in a strategic deal to develop a new generation of optical interconnect for automotive designs

TRUMPF and KDPOF are combining their knowledge in the field of components and networks for data communication based on 980nm VCSEL vertical cavity lasers.

The push to autonomous driving is creating large amounts of data that have to be processed in cars. Consequently, optical interconnects are required to manage the data flow, acting as a nervous system connecting sensors and electronic brains, while meeting tight electro-magnetic interference requirements.

The 980nm VCSEL lasers can operate across wider temperature ranges than other laser, from minus 40 °C up to 125 °C, but also with an interconnect length of 40m. The two companies are part of the IEEE P802.3cz task force. The current draft approved in IEEE 802.3 working group ballot for automotive optical multi-gigabit data transmission. The 980nm lasers can be used with existing OM3 fibre optic cables with only limited dispersion loss.

“With our strategic partnership we are going one step further and aim to establish VCSEL and optical networks as indispensable part in future cars,” said Rubén Pérez-Aranda, CTO at KDPOF in Spain. “Having a supplier like TRUMPF as a partner in working groups enrich the discussion with deep manufacturing and design knowledge of VCSEL and photodiodes components.”

“After a long-term cooperation, it’s great to enter a strategic partnership with KDPOF now, combining our long-term expertise to shape the future of data communication within car networks,” said Joseph Pankert, VP Product Management at TRUMPF Photonic Components in Germany. “Our long-term studies have already proven that 980nm VCSELs can operate at much higher temperatures while maintaining excellent reliability. This is exactly what the automotive industry is demanding, and therefore we support the movement towards a new, long-wavelength standard.”

“The automotive industry is a very demanding”, said Pérez-Aranda. “The IEEE 802.3 standard is therefore focusing on highly reliable conditions that delivers a service life of 15 years and more.”
