With new challenges like automated driving and electric power trains, In-Vehicle Network (IVN) requirements are quickly evolving. The IVN has to support use cases such as the vehicle data backbone, smart antennas, ADAS cameras/sensors, displays, and data loggers, which demand higher data bandwidth while maintaining the reliability level required by the automotive industry. When considering a standard technology to support the target use cases, it is clear that the requirements are not all met by any existing communication standard, including the optical 10GBASE-SR. It is thus necessary to define a new IVN standard for multi-gigabit optical communications in the automotive environment.
This video about automotive multi-gigabit optical connectivity presents the standardized solution under development by KDPOF to reach a 50 Gb/s bit rate over 40 meters of wiring harness. In the process, we’ll comply with the hardest OEM’s EMC specs, and meeting all automotive requirements in terms of operational temperature, reliability, ageing, mechanical loads, chemical loads, dirtiness and harsh environments in general. And all this with outstanding low power and low cost. Please, follow us to the KDPOF labs and we’ll show you a demo of our multi-gigabit solution: 50 Gb/s optical transmission for automotive.
At the virtual Wire Harness Congress (Bordnetz-Kongress) by WEKA Publishing on September 22, 2021, KDPOF displayed the status of optical multi-gigabit connectivity in vehicles. In their presentation, Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, proposed a complete optical communications system, which is under development by KDPOF and their industry partners.
From September 29 to October 1, 2021, KDPOF will display an update on optical gigabit networking in vehicles at the virtual SIAT – Symposium on International Automotive Technology 2021. Cars are not solely about driving anymore – electronic devices such as anti-collision cameras, DVD players, and navigation systems make the difference. Like infotainment systems, Automotive Driver Assistance Systems (ADAS) are becoming an integral part of the vehicle, with interfaces to many different clusters of electric/electronic systems.

At the virtual Wire Harness Congress on September 22, 2020, KDPOF will display insights and update on Optical Multi-Gigabit Connectivity. In their presentation at 15:50, Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, will prove how automotive networks profit from optical technology. Electric and autonomous driving architectures are substantially pushing the challenges for wiring systems. Issues include electromagnetic interference (EMI), electromagnetic susceptibility (EMS), and weight reduction. On top, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously. The new 48-volt electrical architecture in cars additionally pushes the envelope in terms of cross-domain isolation requirements. Copper links for communication rates above 100 Mb/s need heavy and expensive solutions to comply with the stringent OEM’s EMC specs, resulting in high cost and very difficult engineering. Moreover, the weight of the ever-growing diameter of the required cables plays against the race for range increase of electrical powertrains.
The presentation will prove how optical network technology overcomes these trends thanks to its inherent galvanic isolation, robustness, low cost, and low weight. Carmakers will benefit from optical links for communications between the 48-volt and the 12-volt domains. For weight, the optical network will save more than 30 percent of the equivalent copper-based harness weight. Optical Ethernet provides 100 Mb/s and 1 Gb/s network solutions today, and multi-gigabit Ethernet is the significant upcoming breakthrough for in-vehicle networks. The standardization effort for optical multi-gigabit is already in progress within the IEEE as an amendment to the Ethernet standard 802.3.
