Abstract
With the ever-increasing need for faster data communication in cars, electrical interconnects are beginning
to show bandwidth limitations and call for optical interconnects. VCSEL-based multimode interconnects
are a well proven technology in data centers and therefore a natural candidate to also enter automotive
interconnects. Automotive, however, requires operation under more stringent environmental conditions
such as temperature range between −40°C and 125°C. This has led to a new set of specifications for the
optical links, among which is the VCSELs wavelength at 980 nm. The paper describes the properties of
980 nm VCSELs and its use in Automotive environment.
