Future-ready: KDPOF automotive Gigabit Ethernet provides electromagnetic compatibility, robustness, and smooth integration

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. The bandwidth of fiber optics (as compared to traditional automotive cables) and its ease of use, low weight, low cost, coupled with its robustness against vibrations and external noise sources as well as electromagnetic compatibility (EMC) make it ideal for in-vehicle embedded multimedia networks. KDPOF automotive applications incorporate: battery management, safe communications backbones, smart antenna modules, infotainment, lower speed EMC-tight links, autonomous driving safety redundancy, and ADAS sensor interconnection.

We look forward to meeting you online at the event! For any inquiries, please feel free to contact us.

Efficient optical technology from KDPOF for safe backbone in vehicles

On August 13, 2021 from 11:00 a.m. to 12:30 p.m. IST (Indian Standard Time, 6:00 to 7:30 a.m. UTC), Óscar Ciordia, César Esteban, and Kenny Yoon will give the online seminar “The Use of Plastic Optical Fiber in the Automotive Industry”. The seminar is organized by the Society of Automotive Engineers India (SAE India).

Plastic Optical Fiber (POF) is becoming an integral part of the vehicle with interfaces to many different clusters of the electric/electronic systems in the automotive industry. POF is the medium of choice for automotive networks, primarily due to its versatility and is the best alternate solution to existing wiring technology. The key advantages of the optical solution are, among others, Electromagnetic Compatibility (EMC) thanks to its inherent galvanic isolation, robustness, low weight, and low cost. In his seminar, César Esteban will cover the following topics: the need for automotive wire line connectivity to evolve to Ethernet, advantages of optical links, use cases for fiber optics, as well as POF value chain and proposal.

For more information, please see the seminar brochure from SAE India.

Registration is open.

Future-ready: KDPOF automotive Gigabit Ethernet provides electromagnetic compatibility, robustness, and smooth integration

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.
