At the virtual Wire Harness Congress on September 22, 2021, KDPOF will inform about the status of Optical Multi-gigabit Connectivity in vehicles. In their presentation at 11:45, Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, will propose a complete optical communications system, which is under development by KDPOF and their industry partners.

As the auto industry approaches the 50 Gb/s*m speed-length threshold, the need to move from copper to optical physical data transmission media is becoming mandatory. Optical is the engineering-wise path for higher data rates. Together with several industry leaders, KDPOF is working on an optical communications system that will complement existing copper networks. Instead of various single devices, the new solution provides a complete package. The proposed Multi-gigabit system leverages existing technologies, as VCSELs (Vertical-cavity surface-emitting laser), multimode fibers and photodiodes already developed for the data centers industry. It will support Energy-Efficient Ethernet (EEE) tailored for automotive applications. The target BER is better than 10-12 with ambient operating temp from -40ºC up to 105ºC (AEC-Q100 grade 2) in harsh automotive environments. High reliability (15 yrs operation, less than 10 FIT) and outstanding EMC compliance will also be fulfilled. The technology in development is based on advanced digital signal processing based on high-speed DAC and ADC to implement all needed algorithms such as equalization or pre-coding. First engineering samples of the new automotive, single-chip, fully integrated Fiber Optic Transceiver package solution for 10 Gb/s will be available in fall 2021. A new optical automotive IVN communication standard is currently under development within IEEE under the name 802.3cz and is supported by several industry-leading companies.

We look forward to meeting you online at the congress! For any inquiries, please feel free to contact Juergen Schachtschneider.

That is what’s proposed by KDPOF, a Spanish company capable of solving the problems of low quality, which until now this type of fiber had.

César Esteban, Applications & Support Manager of KDPOF: “The signal is digitally processed to adapt the signal to the characteristics of this fiber, which is not glass. It is plastic and has much worse characteristics as a means of communication than glass fiber.”

Plastic fiber is not new. Its great advantage over glass is its robustness. It can be bent, it can get wet, and it doesn’t interfere with other electrical signals, which is very good when there is a lack of space, for example as in cars.

César Esteban, Applications & Support Manager of KDPOF: “That it is much more robust in terms of folding, but also dynamic stresses. It can withstand bending up to five millimeters in diameter, right? In applications we can submerge the connectors, but even if water gets in the transmission, you see that it continues. It’s a really robust technology. The low weight, the low cost, the low power consumption of the technology.”

TV Report by RTVE: Spanish company KDPOF has created a new technology to transmit data at high speed over plastic optical fiber.

The problem with plastic fiber was, in the past, its low quality. What they do at KDPOF that is changing the uses of this technology is to process and adapt the transmitted signal thanks to their own microelectronic technology, despite the noise and distortions. Thanks to this chip they are able to transmit data at one gigabit speed and increasing.

TV Report by RTVE: Spanish company KDPOF has created a new technology to transmit data at high speed over plastic optical fiber.

Rubén Pérez de Aranda, CTO and Co-founder of KDPOF: “So we said, ‘Hey, this fiber is very bad and these light sources that are used to transmit the data are bad in terms of bandwidth and noise, but we know all the algorithmics that can be built.’ And, in fact, we are the first company in the world to have developed advanced systems for fiber optic communications. No one before had ever used such spectrally efficient modulations or such advanced decoding systems as we use in fiber optics. And, in fact, this has been the basis of what will be the future, because we are already developing the next generation for multi-gigabit that will allow cars to drive themselves. Because what we are is the nervous system of a car.”

From there, the uses of plastic fiber are unimaginable. In connected vehicles, they manage to solve the problem of signal interference on the one hand, and on the other they help to reduce the weight of cars.

Carlos Pardo, CEO and Co-founder of KDPOF: “You have, in addition, several computers in parallel. Because for redundancy issues and as it is a safety issue you need to connect the two computers, the amount of information that is moving in cars is rising exponentially and we are offering a very robust solution and, as I said, it is very light, at a very competitive price that really, well, is opening up the market for us in a tremendous way.”

Plastic fiber also solves a domestic problem for demanding users: high speed and low latency in all rooms.

Carlos Pardo, CEO and Co-founder of KDPOF: “The difference between always being dependent on, ‘I have coverage here. Wait for me to move half a meter,’ and when someone passes in front of me I lose the connection; to having a reliable connection where I can play games, where I can watch videos, where I can have meetings without any problems. It’s really life-changing.”

The possibilities offered by this technology, both in vehicles and in homes, offer a more than promising future to connect to every last corner at full speed.

New integrated KD9351 FOT for automotive gigabit connectivity

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.

The video demonstrates the connection and traffic test for the KD1053 evaluation boards included in the automotive evaluation kit.  Connecting gigabit Ethernet over fiber optics, the automotive kit supports OEMs and Tier1 suppliers in technology evaluations. The kit is self-contained and includes all the necessary components to establish 100 and 1000 Mbps links over Plastic Optical Fibers (POF). The boards are versatile, auto-grade for SFP-POF. They are optimized for lab measurements in extreme operating temperatures, radiation, and voltage supply corners.

The automotive evaluation kit contains:

  • 2 SFP-POF media converter boards
  • 15 meters/4 in-line connectors POF harness or 40 meters/0 in-line connectors POF harness
  • 1000BASE-T SFP modules/UTP & SFP twinax cables
  • USB2ALL POF link

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.

Demo: World’s First 50 Gb/s Automotive-grade Optical Network

KDPOF has successfully participated at the virtual ISCAS 2020 in October with several contributions: a presentation on multi-gigabit Ethernet for the automotive industry, an overview lecture on high-speed data communications over POF, and an important role in the final industry panel session. The IEEE International Symposium on Circuits and Systems (ISCAS) is the flagship conference of the IEEE Circuits and Systems (CAS) Society and the world’s premiere networking forum for researchers in the highly active fields of theory, design, and implementation of circuits and systems.

Towards the Multi-Gigabit Ethernet for the Automotive Industry

Session Chairmen Enrique Prefasi Sen, Analog and Mixed Signal Senior Designer of KDPOF, and Alberto Rodríguez-Pérez, Analog and Mixed Signal Manager of KDPOF, have presented the paper “Towards the Multi-Gigabit Ethernet for the Automotive Industry”. The paper, within the special session “Multi-gigabit Wireline & Optical Communication Circuits & Systems Session”, showed the status of Ethernet-based communication solutions, focused on optical links for the automotive industry. They displayed the implementation of a product compatible with the 1000BASE-RHC according to the IEEE Std 802.3bv, which is the first one able to transmit 1 Gbps over POF for automotive. In addition, the KDPOF experts described a new architecture to achieve up to 25 Gbps for automotive. The proposed multi-gigabit system leverages existing technologies such as VCSELs, multi-mode fibers, and photodiodes already developed for the data center industry.

High-Speed Data Communications over Fiber Optics

In his lecture, Alberto Rodríguez-Pérez gave an overview of the use of Plastic Optical Fiber as a medium for optical data communications and the techniques needed to get high speed data bitrates over POF. It is an interesting alternative optical communication channel to the Glass Optical Fibers (GOF) for applications that are not required to cover long distances, such as home or automotive networking. However, the reduced low bandwidth of the POF channel imposes big limitations in the maximum data bitrate that can be transmitted through this medium. Consequently, advanced data communication techniques such as channel equalization, data error correction, or data signal modulation need to be applied to achieve data bitrates above 1 Gbps.

Photonics Days Berlin Brandenburg: Optical Automotive Ethernet Presentation

KDPOF is delighted to present at the virtual Photonics Days Berlin Brandenburg 2020 from October 5 to 8, 2020. On Monday, October 5 at 10:40, César Esteban, Application and Support Manager of KDPOF, will give the presentation “Optical Automotive Ethernet” within the session “Innovative Optical Fibers”. Plastic optical fibers (POF) are the most reliable solution in vehicles since they can withstand harsh environments, vibrations, misalignments, dirtiness, humidity, wide temperature range, etc. Additionally, optical Ethernet generates very low noise and can operate in noisy environments, such as in RF electronic boards.

Full Standardization of Optical Gigabit

Recently, 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. With the new ISO 21111 sections complementing the existing IEEE Std 802.3bvTM, optical Gigabit connectivity is now entirely standardized. Based on these standards, KDPOF’s optical technology allows a complete, compatible, and interoperating implementation for carmakers and Tier1s.

The KD1053 transceiver perfectly meets the requirements of carmakers by providing high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver is optimized for low power and small footprint and transmits data at 1000/100 Mb/s on standard SI-POF, MC-POF, or PCS, according to 1000BASE-RH (IEEE 802.3bv).

Outlook on Optical Multi-Gigabit

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. Consequently, in-vehicle networks are on the brink of speeds from one to multiple gigabits per second. Optical Multi-Gigabit Ethernet in the car is on the verge of standardization and implementation. 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. KDPOF has already displayed the world’s first demonstration of an automotive-grade optical transmission system with 50 gigabits per second single lane, leveraging datacom components.
