Together with several industry leaders, KDPOF is working on an optical automotive multi-gigabit system that will fulfill the needs of future connected and automated vehicles. Instead of various port components, the new solution provides a single, complete package. “As the auto industry approaches the 50 Gb/s*m speed-length threshold, the move from copper to optical physical data transmission media is becoming mandatory,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “Optical is the engineering-wise path for higher data rates.” The new connector systems are very small, lightweight and extremely inexpensive compared to the previous ones. With the comprehensive EVK9351AUT evaluation kit, automotive manufacturers and suppliers can already test the new configuration at 1 Gbit/s today. KDPOF thus supports easy project entry into optical gigabit connectivity for a secure Ethernet backbone and ADAS sensor connections in vehicles. Read more
The new integrated KD9351 Fiber Optic Transceiver (FOT) from KDPOF further reduces costs for optical in-vehicle networks at 1 Gb/s. Incorporating the transmit and receive optoelectronics into one single component, the KD9351 is an optical transceiver for 100 Mb/s up to 1 Gb/s with a small footprint. “Compared to STP (shielded twisted pair of copper wires), the combination of the new KD9351 FOT with the continuing KD1053 IC cuts the cost for 1 Gb/s by 30 percent,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “The new integrated device provides enhanced efficiency and flexibility. It thus paves the way to optical multi-gigabit Ethernet in the vehicle.” Applications for the new KD9351, with competitive pricing for EMC critical or galvanic isolated critical links, include safe Ethernet backbones and sensor links for advanced driver assist systems (ADAS).
KDPOF Provides Efficient Optical Technology for Safe Backbone and ADAS Sensor Links in Vehicles
KDPOF significantly lowers costs for the new KD9351 by constructing the transimpedance amplifier, photodiode, LED driver, and LED as one single device. Additional benefits are a shorter supply chain and no test duplication with the final test at the Tier1. Furthermore, the assembly of the FOT and the existing KD1053 IC is simplified and the connector offers snap-fit without soldering. The KD9351 reuses low-cost MEMs encapsulation and allows SMD reflow assembly with 8 by 7 mm LGA components. It is fully shielded against electromagnetic radiation. Fiber connection is done with a very simple plastic connector placed on top. The temperature range, from -40 °C to +105 °C, conforms with harsh automotive environmental requirements. The FOT withstands motor conditions with a vibration class of V2. Additionally, the device endures water without sealing. EMC performance is excellent even with the ECU shield case removed, as shielding is integrated into the PCB component. Optics implement Tx and Rx lenses. Samples are already available.
KDPOF presents the brand new integrated Fiber Optic Transceiver (FOT) KD7051. It is the first device for optical in-vehicle connectivity that incorporates the transceiver IC, optoelectronics, and optics. The integrated FOT is a 100 Mb/s optical port in one single component. “By constructing the ASIC IC, photodiode and LED as one single device, we significantly reduce cost and footprint for automotive Ethernet connectivity at 100 Mb/s,” stated Carlos Pardo, CEO and Co-Founder of KDPOF. “The decreased number of parts also reduces the effort in testing and qualification.”
Cost and Size Reduction by Integrating Transceiver IC, Optoelectronics, and Optics into One Fiber Optic Transceiver
KDPOF’s new KD7051 thus substantially reduces the overall expense compared to STP (shielded twisted pair of copper wires). Further advantages are no margin stacking between links in the supply chain and supply chain simplification. Consequently, it offers competitive pricing for EMC critical or galvanic isolated critical links. Applications include battery management systems, camera and sensor links, fast Ethernet links and smart antenna links.
All New Physical Layer

As a plastic optical fiber with a large diameter, POF is more cost-effective to manufacture and install: installation is just easy plug and play; winding and clamping is similar to copper cables. Moreover, during the car assembly, the optical harness can be installed in the same process as the copper harness. POF has been present in vehicles for more than 10 years and is installed in millions of cars.
KDPOF has conducted a study examining the influence of home networking on online gaming and video streaming. For online gaming, the delay between an action the player intends to perform in the game and its actual effect on the screen can totally ruin the experience. Among gamers, this latency is known as ping or lag. The action issued by the player has to go through different network segments until it reaches the game server; it is then processed and the response travels back to the gamer. Numbers over 150 ms are a total no-go experience while being under 20 ms is considered a very good behavior.
KDPOF Study Reports Significant Effect of Home Networking on Online Gaming Experience
“There are three main segments that can influence the latency level: online game servers, access network, and home networking,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “Our study showed that the home network plays a key role in the whole experience. Average values as low as 1 ms and up to 30 ms could be found.” A good solution is wired connectivity over plastic optical fiber (POF). It provides very low latency and jitter, just like Ethernet wiring but without visible cabling installed.
The Importance of Low Latency for Home Networks
The number one home network technology used nowadays in any home is Wi-Fi. Unfortunately, it provides little control over when each node has access to the air. Any packet loss is not noticeable for services such as web browsing, but when delivering video related services, these crashes generate peaks of latency. Those packets need to be retransmitted, extending the time required to reach the other end. If a device in the same environment is connected over Ethernet directly to the access router, the picture changes significantly. “It is not surprising that gamers prefer to connect over wires rather than Wi-Fi due to these effects,” added Carlos Pardo. “Delays are getting even worse with the rapid increase of multiple Wi-Fi access points of Wi-Fi mesh in the home.”
Plastic Optical Fiber Combined with Wi-Fi
Since wired connectivity adds only negligible latency to the path, it is recommended over wireless for the in-home portion. With its ease of installation, lack of aesthetic impact, robustness, and stability, plastic optical fiber is the ideal solution to contribute to a perfect online gaming experience. The ultimate home network solution is one that combines the advantages of a POF backbone with Wi-Fi access points throughout the home. It secures 1 Gb/s speed to each access point, avoiding any loss inherently present with wireless due to distance, walls or interference. While Wi-Fi links provide latencies on the level of milliseconds, POF is on the level of microseconds, i.e. 1000 times better.
POF can easily be installed in any duct throughout the home: power, coaxial, or telephone conduits, or easily hidden on walls, under carpets or through false ceilings. Devices that connect to the network via Wi-Fi will continue to use that connection, but will enjoy the dedicated 1 Gb/s speed of the POF network. This way, Wi-Fi speed experienced anywhere in the home is the same as next to the router.

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.
