50 Gb/s Optical Automotive Ethernet Demo Strikes at Automotive Ethernet Congress
50 Gb/s Optical Automotive Ethernet Demo Strikes at Automotive Ethernet Congress

We are grateful and overwhelmed by the great interest we have received for our 50 Gb/s Optical Automotive Ethernet demo at the Automotive Ethernet Congress in Munich in February 2020. During Carlos Pardo’s presentation “Optical Multi-Gigabit Ethernet – on the Verge of IEEE Standardization and Implementation”, the audience listened in spellbound silence before peppering him with technical questions. Our exhibition stand had been well-attended the whole event. Furthermore, after the presentation, it was virtually flooded by interested automotive industry representatives.   

In-vehicle networks are on the brink of speeds from one to multiple gigabits per second. 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 study group evaluates the creation of an IEEE Ethernet standard for the automotive industry, with speeds starting at 2.5 Gb/s, going up to 25 or 50 Gb/s, and scalable up to 100 Gb/s. 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.

The key development objectives for the new standard target outranging performance. The high speed will reach at least 25 Gb/s and will be scalable to 50 or 100 Gb/s. The temperatures range from -40 °C to 105 °C. Distances are 15 meters with 4 inline connectors for cars and 40 meters for cars and buses. Meeting OEM reliability requirements, the failure rate is below 10 FIT (Failures In Time: 1 FIT equals 1 failure per 1,000 devices operating 1 million hours). 

Optical Multi-Gigabit Physical Layer for Automotive Applications

Complexity stays low with simple modulation. For fiber, the OM3 class is chosen, since it is already extensively used by data centers and avionics. Only extensively used light sources will be selected. Two connector grades are defined in order to allow cost-effective implementations. Regarding topology, asymmetric up and down links have been considered from the beginning. The use of the Energy-Efficient- Ethernet (EEE) specification is an appropriate candidate to implement this feature. Cameras, displays, and further asymmetrical use cases have been included as test cases for the standardization. An OAM side-channel will be available for dependability and link management. The absence of retransmissions means controlled latency for video distribution. Symmetric links will be added for backbone communications. 

With cost-down and consistency in focus, optics, fibers, connectors, and electronics already developed for nGBASE-SR will be reused. Further specifications include 850 nm VCSEL, multimode OM3 fiber, PAM2 receivers, and connectors. Standardization work focuses on the automotive requirements: VCSEL reliability for the operation temperature range, connector development with quality grades, standardized wake-up and sleep protocols, and an adaptive DSP to cope with the large parametric deviation of the VCSEL. Increasing the yield percentage results in cost reduction.

Relevant use cases from different carmakers in Europe and the USA incorporate the comprehensive features and benefits of optical network technology. These include the interconnectivity of telematics control modules with the optical links, providing reliable reception and increased dynamic range of detected signals. Redundant and safe backbones for autonomous driving guarantee ASIL-D safety architecture with optical and copper in parallel. Further applications are ADAS interconnections with cameras, lidar, and radar sensors. For battery management systems, optical connectivity delivers galvanic isolation among voltage domains.

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.

KDPOF has signed a partnership agreement with the South Korean software development company Funzin. The goal is to work jointly on high-speed gigabit network products using Plastic Optical Fiber (POF) for automotive electronics and home networks. We will develop network applications for cars, in-home delivery for high-speed Internet, and Internet TV (IPTV).

Funzin supplies 5G frequency verification solutions to major domestic carriers. Founded in 2006, the company also provides a big data solution that combines ADAS for smart cars and machine learning. In 2019, Funzin introduced a fusion solution with driver face recognition and drowsiness detection. “As the volume of data in automobiles increases, the application of POF-based network technology will expand,” stated Kim Jung-Hoon, Vice President of Funzin.

KDPOF offers optical communication technology based on Plastic Optical Fiber (POF) instead of copper wire or glass fiber. It solves the electromagnetic issue with copper cables and overcomes the disadvantages of inflexible glass fiber optics. POF-based converters offer high reliability and ultra-fast data transfer capability. In addition, it improves fuel economy for vehicles. Major components such as cables, converters, and connectors making up a POF network are cheaper and more flexible than conventional optical communication facilities. As a result, POF is evaluated as next-generation network technology with excellent value for investment cost and verification cost. 

Autonomous driving and driver assistance system (ADAS) features have been adopted as main preferences in vehicles, with the automotive network evolving to Ethernet. This is to connect various sensors and central control devices efficiently. In line with this trend, demand for electronic cables is expected to surge.

In addition to automotive applications, home networks also rely on the optical network backbone. It can be connected to IPTV set-top boxes and Wi-Fi APs. As the demand for high-speed Internet grows, its scope of use continues to increase.

KDPOF’s presenting their optical Gigabit Ethernet connectivity with high electromagnetic compatibility at the recent International ELIV (ELectronics In Vehicles) VDI Congress in Bonn, Germany, received great interest. In battery management systems, galvanic isolation is necessary between primary and secondary systems. Due to its inherent galvanic isolation, POF perfectly solves the electrical and interference challenges of new powertrain architectures for electric and autonomous driving. KDPOF is proud that the first application of a Battery Management System (BMS) based on optical connectivity will soon go into production. By the end of 2019, the first carmaker will start assembly of a battery management system with POF connectivity.

Broadband World Forum: KDPOF Presented Guaranteed Wi-Fi Mesh up to 1 Gbps

At the recent Broadband World Forum in Amsterdam, KDPOF generated great interest for their presenting how the POF backbone complements Wi-Fi Mesh for guaranteed gigabit performance. For customers that demand assured performance, POF is the preferred option. POF cables are practically invisible since installers can reuse any existing conduits or install in a very unnoticeable way in the home. Plastic Optical Fiber is cost-efficient, robust, and much easier and quicker to install than Cat 6 cables. Service Providers worldwide will benefit from being able to deliver guaranteed 1 Gigabit connectivity into homes by combining the POF backbone with Wi-Fi Mesh. Ramón Garcia, Business Development Manager with KDPOF, discussed in his presentation ”Gbps: Do Customers Care?” how to satisfy Gbps customers and thereby increase the number of subscribers willing to pay for qualified bandwidth instead of sole connectivity.
