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

KDPOF’s new transceiver IC KD7051 offers a complete new FOT design. It reuses low cost MEMs encapsulation and allows SMD reflow assembly with 8 by 7 mm LGA components. The FOT 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. With a vibration class of V2, it withstands motor conditions. 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. The assembly of the FOT and the IC in the PCB is simplified. Optics implement Tx and Rx lenses. The first prototypes are available.

Simple Implementation

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.

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.
