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.
