Multi-gigabit automotive communication requires a new standard

The new standard is intended to enhance the current IEEE 10GBASE-SR standard, and establish a communications channel in optical fibre at 10 Gb/s.

“Infotainment, ADAS and growing levels of autonomy are the key trends for the exponential growth of data rates: 100 Mbps to 1 Gb/s, 2.5 Gb/s, 5 Gb/s and 10 Gb/s, with some OEMs even targeting 25 and 50 Gb/s for the upcoming years,” explained Carlos Pardo. “An existing standard such as 10GBASE-SR would ideally work for automotive applications. Unfortunately, it does not meet stringent automotive requirements.”

The team pushing for the new standard comprises individuals affiliated with over 15 key carmakers, including PSA, Toyota, and Volvo; Tier1s; and components suppliers. The group has invited a Call for Interest (CFI) with the IEEE’s approval to start the standardization of an IEEE 802.3 Automotive Optical Multi-Gigabit Standard. The working group, headed by Carlos Pardo (KDPOF), will begin in the summer of 2019, and the first prototypes are projected by the end of 2021. The study group will evaluate the creation of an IEEE Ethernet standard for the automotive industry, with speeds starting at 2.5 Gb/s and up to 50 Gb/s.
