Granite River Labs and KDPOF Collaborate to Deliver ISO-Standardized Automotive Ethernet Over Plastic Optical Fiber

ISO 21111 Enables Standardized Design and Testing of Optical Gigabit Networks

Madrid (Spain) and Santa Clara (California, US), August 11, 2020 – Granite River Labs (GRL), a global leader in engineering services and test solutions for connectivity and charging, and KDPOF, leading supplier for gigabit transceivers over POF (Plastic Optical Fiber), announced that a specification for 1 Gb/s optical connectivity in vehicles has been adopted by the International Organization for Standardization (ISO).

“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 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.
