At the IEEE SA Ethernet & IP @ Automotive Technology Week from November 3 to 4, 2021 in Munich, Germany, and online, KDPOF will display their high-speed connectivity solutions for the communications in vehicle data networks. Optical connectivity perfectly solves the electrical challenges and interference in vehicles thanks to its low weight, low cost, and electromagnetic compatibility due to inherent galvanic isolation.
At the virtual Wire Harness Congress on September 22, 2021, KDPOF will inform about the status of Optical Multi-gigabit Connectivity in vehicles. In their presentation at 11:45, Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, will propose a complete optical communications system, which is under development by KDPOF and their industry partners.
As the auto industry approaches the 50 Gb/s*m speed-length threshold, the need to move from copper to optical physical data transmission media is becoming mandatory. Optical is the engineering-wise path for higher data rates. Together with several industry leaders, KDPOF is working on an optical communications system that will complement existing copper networks. Instead of various single devices, the new solution provides a complete package. The proposed Multi-gigabit system leverages existing technologies, as VCSELs (Vertical-cavity surface-emitting laser), multimode fibers and photodiodes already developed for the data centers industry. It will support Energy-Efficient Ethernet (EEE) tailored for automotive applications. 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 yrs operation, less than 10 FIT) and outstanding EMC compliance will also be fulfilled. The technology in development is based on advanced digital signal processing based on high-speed DAC and ADC to implement all needed algorithms such as equalization or pre-coding. First engineering samples of the new automotive, single-chip, fully integrated Fiber Optic Transceiver package solution for 10 Gb/s will be available in fall 2021. A new optical automotive IVN communication standard is currently under development within IEEE under the name 802.3cz and is supported by several industry-leading companies.
We look forward to meeting you online at the congress! For any inquiries, please feel free to contact Juergen Schachtschneider.
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.
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.
Aukua Systems Inc., provider of Ethernet test and monitoring solutions, and KDPOF are proud to announce the success of their technology partnership for ISO 21111 standardization. Recently, two additional sections, ISO 21111-3:2020 and ISO 21111-5:2020, of the international in-vehicle Ethernet ISO standard series 21111 have been published. “By providing their MGA2510 Ethernet Test and Monitoring Platform, Aukua Systems have supremely equipped the test setup for ISO certification,” stated Carlos Pardo, CEO and Co-founder of KDPOF.
Successful Technology Partnership Results in ISO Standard for Optical In-Vehicle Gigabit Connectivity
KDPOF supports the test ecosystem to make sure that ECUs including their technology will be tested by recognized test houses and based on the ISO standard. “We are delighted to support the overall standard for optical gigabit connectivity in vehicles with ISO 21111 complementing the existing IEEE Std 802.3bvTM,” added Suds Rajagopal, Co-Founder at Aukua Systems. “By leveraging Aukua’s test solutions, carmakers and Tier1s now have access to a complete, compatible, and interoperating implementation based on these standards.”
ISO 21111 Standardization
For reliable implementations of systems that implement in-vehicle Ethernet Optical 1 Gb/s as a physical layer, International Organization for Standardization (ISO) has added two new sections to the in-vehicle Ethernet series 21111: ISO 21111-3:2020 specifies additional features to IEEE 802.3bv, such as wake-up and synchronized link sleep algorithms. ISO 21111-5:2020 specifies requirements at the system level and a complete conformance and interoperability test plan for ECU providers that implement optical 1 Gb/s physical layer as specified in ISO 21111-3.
