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.

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.

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.
