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:

KDPOF will proudly display the world’s first demonstration of an automotive-grade optical transmission system with 50 gigabits per second single lane at the Automotive Ethernet Congress from February 12 to 13, 2020 in Munich, Germany. In his presentation, “Optical Multi-Gigabit Ethernet – on the Verge of Standardization and Implementation,” on February 13 at 14:30, Carlos Pardo, CEO and Co-founder of KDPOF, will show details on the process for the new standard for multi-gigabit in automotive. It will enhance the existing 10GBASE-SR, which is the current standard by IEEE, to establish a communications channel in optical fiber at 10 Gb/s. “With technological leaps such as electrical vehicles, automated driving, and V2X interconnection rushing through, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously,” explained Carlos Pardo. “Consequently, in-vehicle networks are on the brink of speeds from one to multiple gigabits per second.”
IEEE 802.3 Automotive Optical Multi-Gigabit Standard
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 working group headed by Carlos Pardo (KDPOF) kicked off last summer. The first prototypes are projected by the end of 2021. The study group will evaluate the creation of an IEEE Ethernet standard for the automotive industry, with speeds starting at 2.5 Gb/s and going up to 25 or 50 Gb/s.
Optical Multi-Gigabit Ethernet – on the Verge of Standardization and Implementation
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. Relevant use cases from different carmakers in Europe and the USA incorporate the comprehensive features and benefits of the optical network technology. Use cases include the interconnectivity of telematics control modules, redundant and safe backbones for autonomous driving architectures, and advanced driver assist system (ADAS) sensors.
Key leading optoelectronic, connector, and wire harness vendors worldwide are prepared and already provide a well-supplied and competitive market with all the new components needed for multi-gigabit in the car: Physical Layer (PHY), Fiber Optic Transceiver (FOT), fibers, connectors, and light sources. The technology will be scalable in order to enable even higher data rates such as 50 and 100 Gb/s in the future. By combining optimization in all areas of the new standard, the right balance of complexity and cost among all parts (CMOS IC, VCSEL, PD, ferrules, sleeves, cable, in-line connection technology, optics, and lenses, etc.) can be achieved in order to deliver the lowest cost, most reliable, and highly scalable solution to the automotive market.

Optical connections with POF are ideal for galvanic isolation in battery management systems
KDPOF proudly announces that the first application of a Battery Management System (BMS) based on optical connectivity will soon go into production. “We are delighted that by the end of 2019, the first carmaker will start assembly of a battery management system with POF connectivity,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “Due to its inherent galvanic isolation, POF perfectly solves the electrical and interference challenges of new powertrain architectures for electric and autonomous driving.” In battery management systems, galvanic isolation is necessary between primary and secondary systems due to hazardous high voltages and noise isolation. Further applications that rely on the inherent Electromagnetic Compatibility (EMC) of POF are Integrated Smart Antenna (ISA) modules. For ISA, KDPOF and ALPS have developed a concept for an LTE-A telematics control module with POF links to the central communications hub in order to avoid interference with the smart antenna receivers. KDPOF’s GEPOF transceiver KD1053 provides high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time.
KDPOF will present their optical Gigabit Ethernet Connectivity with high electromagnetic compatibility at IEEE-SA Ethernet & IP @ Automotive Technology Day on September 24-25, 2019 in Detroit, Michigan, USA, and ELIV (ELectronics In Vehicles) International VDI Congress on October 16-17, 2019 in Bonn, Germany.

As part of a team of automotive companies, Carlos Pardo, CEO and Co-founder of KDPOF – leading supplier for gigabit transceivers over POF (Plastic Optical Fiber) – is driving a new standard for multi-gigabit in automotive. It will enhance the existing 10GBASE-SR, which is the current standard by IEEE, to establish a communications channel in optical fiber at 10 Gb/s. “Infotainment, ADAS and growing levels of autonomy are the key trends for the exponential growth of data rates: 100 Mbps to 1 Gb/s, 2.5 Gb/s, 5 Gb/s and 10 Gb/s, with some OEMs even targeting 25 and 50 Gb/s for the upcoming years,” explained Carlos Pardo. “An existing standard such as 10GBASE-SR would ideally work for automotive applications. Unfortunately, it does not meet stringent automotive requirements.”
Multi-Gigabit Communications Demand New Automotive Standard
The team of individuals affiliated with more than 15 key carmakers, such as PSA, Toyota, and Volvo; Tier1s; and components suppliers, including KDPOF, is specifying the needs and technologies to support a new multi-gigabit standard. The group led a Call for Interest (CFI) with the approval of the IEEE to start the standardization of an IEEE 802.3 Automotive Optical Multi-Gigabit Standard with strong support from the industry. The working group headed by Carlos Pardo (KDPOF) will kick off in the summer of 2019, with the first prototypes to be projected by the end of 2021. The study group will evaluate the creation of an IEEE Ethernet standard for the automotive industry, with speeds starting at 2.5 Gb/s and up to 50 Gb/s.
Targeting IEEE 802.3 Automotive Optical Multi-Gigabit Standard
The current IEEE standard 10GBASE-SR was originally created to meet the demands of data centers where temperature, operational life, price, reliability and mechanical robustness are very controlled and modest. With the harsh automotive environment, in addition to power consumption and especially cost being key in automotive applications, only a new communications scheme can provide enhanced robustness and adapt itself automatically to varying environmental conditions and manufacturing processes. Moreover, the technology should be scalable in order to enable even higher data rates such as 25, 50, and 100 Gbps in the future. By combining optimization in all areas of the new standard, the right balance of complexity and cost among all parts (CMOS IC, VCSEL, PD, ferrules, sleeves, cable, in-line connection technology, optics, and lenses, etc.) can be achieved in order to deliver the lowest cost, most reliable, and highly scalable solution to the automotive market.

KDPOF presents an optical link concept for telematics control modules. “Several OEMs choose the IEEE Std 802.3bv™ for Gigabit Ethernet over POF (GEPOF), which is the ideal solution to connect Smart Antenna to the central communications hub while avoiding electromagnetic interference (EMI),” explained Carlos Pardo, CEO and Co-founder of KDPOF. “The optical link enhances antenna performance, whereas in conventional systems, antenna reception sensitivity is reduced by the radiated emissions coming from the electrical communications links, such as UTP (Unshielded Twisted Pair) copper cables, coax, and the shielded alternatives.” KDPOF, in partnership with ALPS, has developed a concept for an LTE-A telematics control module that uses Gigabit Ethernet over POF to connect to the central communications hub such as a head unit.
Optical Gigabit Connectivity Secures High Electromagnetic Compatibility
Since POF provides inherently high Electromagnetic Compatibility (EMC), the links do not interfere with the smart antenna receivers. With the necessary speed going beyond 100 Mbps, a 1 Gbps Ethernet link is required. Moreover, substituting the current RF link with an Ethernet data link will not only aggregate LTE-A packets but other sources such as digital radio as well.
Optical Link Concept for Smart Antenna
New plastic, composite and crystal roofs or roofs with openings do not shield the antenna from electromagnetic noise generated inside the car compartment. Instead, a significant amount of energy is radiated by the coaxial cable that is coupled back into the Integrated Smart Antenna (ISA) electronics, which severely degrades its performance. The natural EMC problem-free POF is ideally suited for an Ethernet connection, avoiding back-coupling conditions like the above mentioned one. In addition, the EMC problem-free link permits simple re-positioning of the antenna module among vehicle configurations. Another advantage is the simple integration with current ISA chipsets thanks to the Ethernet (SGMII/RGMII) host bus of the Gigabit POF transceiver. Furthermore, thanks to the Gigabit capacity of the Ethernet link over POF, the data link will aggregate various data streams such as LTE-A, Wi-Fi, V2x, RDS, DAB radio, etc.
KDPOF will present their optical link concept with Gigabit Ethernet over POF for telematics control modules at the Nikkei Automotive Ethernet Tech Days on June 5 and 6, 2019 in Osaka, Japan.

KDPOF boosts Wi-Fi performance to the next level for homes and small and home offices. “With our robust, low latency Plastic Optical Fiber, we provide the highest Wi-Fi mesh performance with a guaranteed 1 Gigabit per second to each access point,” stated Carlos Pardo, CEO and Co-Founder of KDPOF. “Our field study with a tier one Service Provider proves that, in combination with Wi-Fi mesh nodes, the in-wall POF backbone raises performance throughout the house to over 350 percent in flats and up to 560 percent in multistory houses, compared with using a Wi-Fi backbone.” Plastic Optical Fiber is cost-efficient, low skill to install, and robust. POF can reuse any existing conduits in the home, making the cables invisible. It is much easier and quicker to install than Cat 6 cables. In addition to being used as a backbone for home networking, POF provides convenient Optical Network Termination (ONT) to GW link for a better placement of the Gateway (GW) within the home. By working with KDPOF, operators can satisfy their clients by providing very low latency, reduced jitter, fast download speeds, and reliable connectivity for video.
Field Study Confirms Superiority of Combined POF/Wi-Fi Backbone
KDPOF has conducted the field study to compare Wi-Fi performance using the same additional Wi-Fi Mesh nodes in three different types of homes: single-family houses, multistory houses, and flats. One study group used a POF backbone and the other used a Wi-Fi backbone. Transmission speed was measured in three selected rooms in each case. The results were explicit and significant: averaged out of the 20 family test houses, the POF backbone brought about an improvement of more than 400 percent, while a pure Wi-Fi backbone had a limited performance of up to 80 Mbps in 50 percent of the houses. In the multistory houses, the POF backbone’s performance enhancement reached over 560 percent, whereas Wi-Fi only had a reduced output of up to 62 Mbps. Despite the limited number of Wi-Fi end points used in the test, the numbers provided by the Wi-Fi backbone fall far short of the access speeds users have started to enjoy up to their homes. By using the same Wi-Fi Mesh nodes with a POF backbone, the end user experience achieves those numbers. End users experience what they pay for.
Another important result was that with only one more access point with POF as the backbone, performance is significantly better sustained than with two additional access points with a Wi-Fi backbone. POF Backbone simplifies the Wi-Fi mesh architecture and reduces costs while improving overall performance substantially.
KDPOF will present their robust in-wall optical connectivity at stand 3 at Broadband Forum Asia on May 7-8, 2019 in Bangkok, Thailand. In his presentation “Bringing WiFi Performance to the Next Level” on 7 May at 12:20, Ramón Garcia, Business Development Manager with KDPOF, will explain options and good practices for how to transform access speeds into Wi-Fi speeds for a Gigabit experience.

KDPOF – leading supplier for gigabit transceivers over POF (Plastic Optical Fiber) – will present automotive Gigabit Ethernet POF (GEPOF) for future wire harness architectures at stand 18 at the 7th International Conference Automotive Wire Harness on March 26 and 27, 2019 in Ludwigsburg, Germany. “With its inherent galvanic isolation and robustness, the optical Ethernet technology ideally suits current and future in-vehicle network infrastructure,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “POF lives up to the challenges of electromagnetic compatibility and safety requirements created by the new 48-volt electrical architecture.” A well-supplied and competitive market worldwide ensures seamless integration into the wire harness of the vehicle. The inherent Electromagnetic Compatibility (EMC) makes POF perfectly suitable for applications such as Battery Management Systems (BMS) and Integrated Smart Antenna (ISA) modules. Autonomous driving relies on POF for a redundant system in addition to copper cabling in order to increase safety and avoid the autonomous car locking up if one of the systems is disturbed in some way.
POF cables are very reliable: they can withstand harsh environments, vibrations, and misalignments. In addition, POF allows fast dynamic bending, tight bending, and dark liquid immersion in addition to delivering low noise and robustness regarding in-coupling of electromagnetic fields. As a plastic, wide diameter fiber, POF is cheap to manufacture and install: installation is just easy plug and play; winding and clamping is similar to copper cables. With the first automotive Gigabit Ethernet POF transceiver KD1053, KDPOF provides high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver complies with the standard amendment IEEE Std 802.3bv™ and thus fully meets the requirements of carmakers.
KDPOF provide their optical network technology in order to enhance safety for autonomous driving. “For safety-related functions such as the data network backbone, autonomous driving requires redundant systems in order to increase safety and avoid the autonomous car locking up if one of the systems is disabled in some way,” explained Rubén Pérez de Aranda, CTO and Co-founder of KDPOF. Reliability analysis shows that a technology redundancy like optical and copper cabling provides the highest reliability. Consequently, more and more OEMs are now considering Plastic Optical Fiber.
EMC Lessons Learned on Gigabit Ethernet Implementation for ADAS & AV
The lessons learned in the iterative design process give KDPOF the knowledge to bring into the market a mass-produced automotive Gigabit Ethernet PHY integrated in an ECU and meeting the most stringent EMC specifications. “This grows more important as in-car network speeds increase to accommodate the demands of driverless systems,” he added. “Higher speeds are achieved by wider use of the electromagnetic spectrum.”
Rubén Pérez de Aranda is CTO and Co-Founder of KDPOF
This situation makes the underlying communication system implementation less immune to radiated and conducted noise. It also forces OEMs to impose more and more stringent emissions limits on the electronic components, limits that are often already tighter than the demands imposed by international standards. POF is ideal for the new architectures since it provides natural galvanic isolation between communicating modules and a radiation-free harness.
With the first automotive Gigabit Ethernet POF (GEPOF) transceiver KD1053, KDPOF provides high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver complies with the standard amendment IEEE Std 802.3bv™ and thus fully meets the requirements of carmakers.
