KDPOF presents 25 Gbps optical network for vehicles
The new standard will extend the existing 10GBASE-SR, the current IEEE standard, to establish a communication channel in 10 Gbit/s optical fiber. “Technology leaps such as electric vehicles, automated driving and V2X connections are rapidly gaining ground,” explains Carlos Pardo. “As a result, the necessary network speed in the automotive sector is increasing enormously with the applications, workload and safety requirements. Accordingly, automotive networks are at the threshold of speeds from one to several gigabits per second”.
With the approval of the IEEE 802.3 working group, the KDPOF developers have begun standardizing an IEEE 802.3 Automotive Multi-Gigabit Optical Standard in cooperation with more than 15 automotive manufacturers and component suppliers. The working group under the personal leadership of KDPOF CEO Carlos Pardo gave the starting signal last summer. The first prototypes are planned by the end of 2021. The working group will evaluate the creation of an IEEE Ethernet standard for the automotive industry with speeds from 2.5 Gbit/s to 25 or 50 Gbit/s.
The main advantages of an optical solution for specific applications with multi-gigabit speeds with in-vehicle connectivity include electromagnetic compatibility (EMC) thanks to inherent electrical isolation, light weight and low cost. Applications include the networkability of telematics control modules, redundant and secure backbones for autonomous driving architectures and advanced driver assistance systems (ADAS).
Manufacturers of optoelectronics, connectors and wiring harnesses are prepared for the new technology and have already established a competitive market with all new components that require multi-gigabit networks in the car: Physical Layer (PHY), Fiber Optic Transceiver (FOT), fiber, connectors and light sources. The technology will be scalable to enable even higher data rates such as 50 and 100 Gbps in the future. Once all areas of the new standard are optimized and combined, a good balance of complexity and cost can be achieved between all parts (CMOS IC, VCSEL, PD, sleeves, cables, in-line interconnection, optics and lenses, etc.).
KDPOF plans to demonstrate a first version of its technology at the Automotive Ethernet Congress in Munich from February 12th to 13th, 2020.
