Optical multi-gigabit automotive standard achieves milestone
Summary
These industry leaders have been working on an optical automotive multi-gigabit system that will fulfill the needs of future connected and automated vehicles. The proposed IEEE 802.3 automotive optical multi-gigabit standard draft specifies 2.5GBASE-AU, 5GBASE-AU, 10GBASE-AU, 25GBASE-AU, and 50GBASE-AU using bend insensitive OM3 glass fiber. The technology in development is based on advanced digital signal processing, using high-speed DAC and ADC to implement all needed algorithms such as equalization or pre-coding. Reasons include temperatures, life ranges, reliability, vibration, dust, aging, cost restrictions, harness routing, low power, and high production yield, among others. Moreover, a prospective standard should be a scalable technology in order to enable even higher data rates such as 25, 50, and 100 Gb/s, as carmakers predict.
