TRUMPF Photonic Components and KDPOF have become strategic partners in automotive data communication solutions. The two companies are combining their expertise in components and networks for optical data communication.
"With our strategic partnership, we are going a step further and aim to establish VCSELs and optical networks as an indispensable part of the cars of the future. Having a supplier like TRUMPF as a partner in the working groups enriches the discussion with a deep understanding of the manufacturing and design of VCSEL components and photodiodes," explains Rubén Pérez-Aranda, CTO of KDPOF.
TRUMPF states that, due to the automotive industry's push towards autonomous driving, a vast amount of data needs to be processed in vehicles. Consequently, optical interconnects are necessary to manage the data flow, acting as a nervous system that connects sensors and electronic control units, while also meeting stringent electromagnetic interference requirements.
"After a long collaboration, it's great to now enter into a strategic partnership with KDPOF, combining our long-term expertise to shape the future of data communication within automotive networks," says Joseph Pankert, Vice President of Product Management at TRUMPF Photonic Components.
"Our long-term studies have already shown that 980 nm VCSELs can operate at much higher temperatures while maintaining excellent reliability. This is what the automotive industry demands, and we therefore support the move towards a new long-wavelength standard," Pankert adds.
Compared to data centers, automotive applications not only require a much wider operating temperature range, from -40°C to +125°C, but also interconnect lengths of less than 40 meters. Due to its robustness against wear and random failures, 980 nm VCSEL is recognized as the preferred wavelength to become the new standard. In addition to its performance characteristics, 980 nm fits into existing OM3 fibers with limited dispersion loss.
Both TRUMPF and KDPOF participate in the IEEE P802.3cz working group. The current draft approved by the IEEE 802.3 working group vote for multigigabit optical data transmission in the automotive sector provides optical specifications that utilize reliable light sources based on proven longer-wavelength technology. Driver assistance and the operation of autonomous vehicles will benefit from equipment manufactured with standardized components.
"The automotive industry is very demanding. That's why the IEEE 802.3 standard focuses on high reliability conditions that offer a useful life of 15 years or more," says Pérez-Aranda.
