“GRL is proud to support ISO-standardized Gigabit Ethernet POF (GEPOF) test services and automated test solutions,” said Vamshi Kandalla, Executive Vice President and General Manager of Granite River Labs. “Extending our automotive ethernet testing profile further supports automotive hardware developers, including ECU vendors, to confidently deploy robust, interoperable products and technologies.”

“With ISO standardization of GEPOF, we and GRL jointly provide the network technology to enable new and emerging connected car technologies,” added Carlos Pardo, CEO and Co-Founder of KDPOF. “Carmakers and Tier1 suppliers benefit from integrated, compatible, and interoperable implementation based on our KD1053 IC and GRL’s competencies to perform conformance tests.”

ISO 21111 Enables Standardized Design and Testing of Optical Gigabit Networks

ISO published two new standards for in-vehicle Ethernet series 21111, forming the basis for reliable implementations of systems that realize in-vehicle 1 Gb/s Optical Ethernet as a physical layer. ISO 21111-3:2020 specifies additional features to IEEE 802.3bvTM, 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 electronic control unit (ECU) providers that implement an optical 1 Gb/s physical layer as specified in ISO 21111-3.

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.

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.
