Demo setup of the optical multi-gigabit system solution from KDPOF for in-vehicle connectivity

Together with several industry leaders, KDPOF is working on an optical automotive multi-gigabit system that will fulfill the needs of future connected and automated vehicles. Instead of various port components, the new solution provides a single, complete package. “As the auto industry approaches the 50 Gb/s*m speed-length threshold, the move from copper to optical physical data transmission media is becoming mandatory,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “Optical is the engineering-wise path for higher data rates.” The new connector systems are very small, lightweight and extremely inexpensive compared to the previous ones. With the comprehensive EVK9351AUT evaluation kit, automotive manufacturers and suppliers can already test the new configuration at 1 Gbit/s today. KDPOF thus supports easy project entry into optical gigabit connectivity for a secure Ethernet backbone and ADAS sensor connections in vehicles.

KDPOF will present their optical Multi-gigabit Ethernet Connectivity System at ELIV (Electronics In Vehicles) International VDI Congress on October 20 to 21, 2021 at stand 38 in Bonn, Germany, and online.

Off-the-shelf System Solution for In-vehicle Networking

The key advantages of the optical solution, among others, are superior Electromagnetic Compatibility (EMC) thanks to the inherent galvanic isolation, low weight, and low cost. The optical cables are absolutely reliable and at least as flexible as copper cables in the same bandwidth range. They allow fast, dynamic and tight bending as well as immersion in dark liquids. In addition, optical connectivity guarantees easy engineering for seamless implementation. The ecosystem already exists since the system leverages well-proven technologies, such as VCSELs (Vertical-cavity surface-emitting laser), multimode fibers and photodiodes already developed for the data centers industry. The technology will be scalable in order to enable even higher data rates, such as 50 and 100 Gb/s, in the future. Standardization processes are ongoing with IEEE 802.3 Automotive Ethernet and ISO PWI 24581 in progress. The robust and reliable system solution provided by KDPOF and industry leaders thus offers the future-proven path to high speeds.

Reliable, Robust and Cost-efficient

The proposed Multi-gigabit system supports Energy-Efficient Ethernet (EEE) tailored for automotive applications and wakes up in less than 100 ms. The target BER is better than 10-12 with ambient operating temp from -40ºC up to 105ºC (AEC-Q100 grade 2) in harsh automotive environments. High reliability (15 years operation, less than 10 FIT) and outstanding EMC compliance are also fulfilled. 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. A new optical automotive IVN communication standard IEEE 802.3cz is currently in the task force phase and is targeting data rates of 2.5, 5, 10, 25, and 50 Gb/s. It is supported by several industry-leading companies. First engineering samples of the new automotive, single-chip, fully integrated Fiber Optic Transceiver package solution for 10 Gb/s will be available from KDPOF in fall 2022.

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.

IEEE 802.3 Automotive Optical Multi-Gigabit Standard

With technological leaps such as electrical vehicles, automated driving, and V2X interconnection rushing forward, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously. Consequently, in-vehicle networks are on the brink of speeds from one to multiple gigabits per second. With the approval of the IEEE 802.3 working group, a team of individuals affiliated with more than 15 key carmakers and components suppliers, including KDPOF, is working on the standardization of an IEEE 802.3 Automotive Optical Multi-Gigabit Standard with strong support from the industry.

The key advantages of the optical solution for specific applications using multi-gigabit speeds with in-vehicle connectivity are, among others, Electromagnetic Compatibility (EMC) thanks to the inherent galvanic isolation, low weight, and low cost. Use cases include the interconnectivity of telematics control modules, redundant and safe backbones for autonomous driving architectures, and advanced driver assist system (ADAS) sensors. The technology will be scalable in order to enable even higher data rates such as 50 and 100 Gbps in the future. By combining optimization in all areas of the new standard, the right balance of complexity and cost among all parts (CMOS IC, VCSEL, PD, ferrules, sleeves, cable, in-line connection technology, optics, and lenses, etc.) can be achieved in order to deliver the lowest cost, most reliable, and most highly scalable solution to the automotive market.

KDPOF is looking forward to participating in the upcoming virtual ISCAS 2020 from October 10 to 21 with several contributions: a presentation on multi-gigabit Ethernet for the automotive industry, an overview lecture on high-speed data communications over POF, and an important role in the final industry panel session. The IEEE International Symposium on Circuits and Systems (ISCAS) is the flagship conference of the IEEE Circuits and Systems (CAS) Society and the world’s premiere networking forum for researchers in the highly active fields of theory, design, and implementation of circuits and systems.

Presentation: Towards the Multi-Gigabit Ethernet for the Automotive Industry

On Tuesday, October 13, 2020, from 17:15 to 18:55, session Chairmen Enrique Prefasi Sen, Analog and Mixed Signal Senior Designer of KDPOF, and Alberto Rodríguez-Pérez, Analog and Mixed Signal Manager of KDPOF, will present the paper “Towards the Multi-Gigabit Ethernet for the Automotive Industry”. The paper, within the special session “Multi-gigabit Wireline & Optical Communication Circuits & Systems Session”, will show the status of Ethernet-based communication solutions, focused on optical links for the automotive industry. First, the presenters will display the implementation of a product compatible with the 1000BASE-RHC according to the IEEE Std 802.3bv, which is the first one able to transmit 1 Gbps over POF for automotive. Second, the KDPOF experts will describe a new architecture to achieve up to 25 Gbps for automotive. The proposed multi-gigabit system leverages existing technologies such as VCSELs, multi-mode fibers, and photodiodes already developed for the data center industry.

Lecture: High-Speed Data Communications over Plastic Optical Fibers

Alberto Rodríguez-Pérez will give an overview lecture on Saturday, October 17, 2020, from 16:00 to 16:45 in virtual room 2. In his lecture, Alberto will show an overview of the use of Plastic Optical Fiber as a medium for optical data communications and the techniques needed to get high speed data bitrates over POF. It is an interesting alternative optical communication channel to the Glass Optical Fibers (GOF) for applications that are not required to cover long distances, such as home or automotive networking. However, the reduced low bandwidth of the POF channel imposes big limitations in the maximum data bitrate that can be transmitted through this medium. Consequently, advanced data communication techniques such as channel equalization, data error correction, or data signal modulation need to be applied to achieve data bitrates above 1 Gbps.

Industry Panel

KDPOF is also substantially involved in the final Industrial Panel Discussion on Wednesday, October 21, 2020, from 16:45 to 17:45. Alberto Rodríguez-Pérez will chair the panel and Rubén Pérez de Aranda, CTO of KDPOF, will participate as panelist.
