KDPOF welcomes the publication of two additional standards in the frame of the international in-vehicle Ethernet ISO standard series 21111. The supplementary parts, ISO 21111-3:2020 and ISO 21111-5:2020, specify further features for in-vehicle data transmission of 1 Gigabit per second over POF technology. “With the new ISO 21111 sections complementing the existing IEEE Std 802.3bvTM, optical Gigabit connectivity is now entirely standardized,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “Based on these standards, our optical technology allows a complete, compatible, and interoperating implementation for carmakers and Tier1s.”

Publication of ISO 21111

ISO (International Organization for Standardization) has added two new sections to the in-vehicle Ethernet series 21111. These newly approved parts are key components to assure reliable implementations of systems that realize in-vehicle Ethernet Optical 1 Gb/s as a physical layer.

ISO 21111-3:2020 specifies additional features to IEEE 802.3bv, such as wake-up and synchronized link sleep algorithms. It also contains a complete conformance test plan for IC providers that implement this standard.

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.

Further relevant parts of ISO 21111 for this type of high speed in-vehicle communications include:

  • ISO 21111-1 provides general definitions.
  • ISO 21111-2 defines general wake-up and sleep definitions and RGMII specifications.
  • ISO 21111-4:2020 is devoted to optical connectivity component specification and tests.

We are proud that Actelser has implemented our optical connectivity technology in their new Snap Data Duplex Kit for home networks. With the Snap Data Duplex Kit, Actelser enables Ethernet over Plastic Optical Fiber (POF) at two additional points. The system allows multiple access ports all around the home in high optical fiber quality.

This means users may enjoy 100 percent of the bandwidth they have signed up for with their service providers. Optical backbones for home networks are the ideal means to leave behind the speed losses of Wi-Fi Repeaters or PLC, since POF systems are completely lossless.

Carlos Pardo, KDPOF CEO, speaking about Optical Multi-Gigabit Ethernet on the Verge of Standardization and Implementation at the Automotive Ethernet Congress in February 2020 in Munich, Germany. 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, has started 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.

We are grateful and overwhelmed by the great interest we have received for our 50 Gb/s Optical Automotive Ethernet demo at the Automotive Ethernet Congress in Munich in February 2020. During Carlos Pardo’s presentation “Optical Multi-Gigabit Ethernet – on the Verge of IEEE Standardization and Implementation”, the audience listened in spellbound silence before peppering him with technical questions. Our exhibition stand had been well-attended the whole event. Furthermore, after the presentation, it was virtually flooded by interested automotive industry representatives.

The key development objectives for the new standard target outranging performance. The high speed will reach at least 25 Gb/s and will be scalable to 50 or 100 Gb/s. The temperatures range from -40 °C to 105 °C. Distances are 15 meters with 4 inline connectors for cars and 40 meters for cars and buses. Meeting OEM reliability requirements, the failure rate is below 10 FIT (Failures In Time: 1 FIT equals 1 failure per 1,000 devices operating 1 million hours). 

Optical Multi-Gigabit Physical Layer for Automotive Applications

Complexity stays low with simple modulation. For fiber, the OM3 class is chosen, since it is already extensively used by data centers and avionics. Only extensively used light sources will be selected. Two connector grades are defined in order to allow cost-effective implementations. Regarding topology, asymmetric up and down links have been considered from the beginning. The use of the Energy-Efficient- Ethernet (EEE) specification is an appropriate candidate to implement this feature. Cameras, displays, and further asymmetrical use cases have been included as test cases for the standardization. An OAM side-channel will be available for dependability and link management. The absence of retransmissions means controlled latency for video distribution. Symmetric links will be added for backbone communications. 

With cost-down and consistency in focus, optics, fibers, connectors, and electronics already developed for nGBASE-SR will be reused. Further specifications include 850 nm VCSEL, multimode OM3 fiber, PAM2 receivers, and connectors. Standardization work focuses on the automotive requirements: VCSEL reliability for the operation temperature range, connector development with quality grades, standardized wake-up and sleep protocols, and an adaptive DSP to cope with the large parametric deviation of the VCSEL. Increasing the yield percentage results in cost reduction.

Relevant use cases from different carmakers in Europe and the USA incorporate the comprehensive features and benefits of optical network technology. These include the interconnectivity of telematics control modules with the optical links, providing reliable reception and increased dynamic range of detected signals. Redundant and safe backbones for autonomous driving guarantee ASIL-D safety architecture with optical and copper in parallel. Further applications are ADAS interconnections with cameras, lidar, and radar sensors. For battery management systems, optical connectivity delivers galvanic isolation among voltage domains.
