KDPOF presents an optical link concept with Gigabit Ethernet over POF for telematics control modules

KDPOF presents an optical link concept for telematics control modules. “Several OEMs choose the IEEE Std 802.3bv™ for Gigabit Ethernet over POF (GEPOF), which is the ideal solution to connect Smart Antenna to the central communications hub while avoiding electromagnetic interference (EMI),” explained Carlos Pardo, CEO and Co-founder of KDPOF. “The optical link enhances antenna performance, whereas in conventional systems, antenna reception sensitivity is reduced by the radiated emissions coming from the electrical communications links, such as UTP (Unshielded Twisted Pair) copper cables, coax, and the shielded alternatives.” KDPOF, in partnership with ALPS, has developed a concept for an LTE-A telematics control module that uses Gigabit Ethernet over POF to connect to the central communications hub such as a head unit.

Optical Gigabit Connectivity Secures High Electromagnetic Compatibility

Since POF provides inherently high Electromagnetic Compatibility (EMC), the links do not interfere with the smart antenna receivers. With the necessary speed going beyond 100 Mbps, a 1 Gbps Ethernet link is required. Moreover, substituting the current RF link with an Ethernet data link will not only aggregate LTE-A packets but other sources such as digital radio as well. 

Optical Link Concept for Smart Antenna

New plastic, composite and crystal roofs or roofs with openings do not shield the antenna from electromagnetic noise generated inside the car compartment. Instead, a significant amount of energy is radiated by the coaxial cable that is coupled back into the Integrated Smart Antenna (ISA) electronics, which severely degrades its performance. The natural EMC problem-free POF is ideally suited for an Ethernet connection, avoiding back-coupling conditions like the above mentioned one. In addition, the EMC problem-free link permits simple re-positioning of the antenna module among vehicle configurations. Another advantage is the simple integration with current ISA chipsets thanks to the Ethernet (SGMII/RGMII) host bus of the Gigabit POF transceiver. Furthermore, thanks to the Gigabit capacity of the Ethernet link over POF, the data link will aggregate various data streams such as LTE-A, Wi-Fi, V2x, RDS, DAB radio, etc.

KDPOF will present their optical link concept with Gigabit Ethernet over POF for telematics control modules at the Nikkei Automotive Ethernet Tech Days on June 5 and 6, 2019 in Osaka, Japan.

KDPOF robust, low latency POF backbone provides guaranteed Gigabit Wi-Fi mesh

KDPOF boosts Wi-Fi performance to the next level for homes and small and home offices. “With our robust, low latency Plastic Optical Fiber, we provide the highest Wi-Fi mesh performance with a guaranteed 1 Gigabit per second to each access point,” stated Carlos Pardo, CEO and Co-Founder of KDPOF. “Our field study with a tier one Service Provider proves that, in combination with Wi-Fi mesh nodes, the in-wall POF backbone raises performance throughout the house to over 350 percent in flats and up to 560 percent in multistory houses, compared with using a Wi-Fi backbone.” Plastic Optical Fiber is cost-efficient, low skill to install, and robust. POF can reuse any existing conduits in the home, making the cables invisible. It is much easier and quicker to install than Cat 6 cables. In addition to being used as a backbone for home networking, POF provides convenient Optical Network Termination (ONT) to GW link for a better placement of the Gateway (GW) within the home. By working with KDPOF, operators can satisfy their clients by providing very low latency, reduced jitter, fast download speeds, and reliable connectivity for video.

Field Study Confirms Superiority of Combined POF/Wi-Fi Backbone

KDPOF has conducted the field study to compare Wi-Fi performance using the same additional Wi-Fi Mesh nodes in three different types of homes: single-family houses, multistory houses, and flats. One study group used a POF backbone and the other used a Wi-Fi backbone. Transmission speed was measured in three selected rooms in each case. The results were explicit and significant: averaged out of the 20 family test houses, the POF backbone brought about an improvement of more than 400 percent, while a pure Wi-Fi backbone had a limited performance of up to 80 Mbps in 50 percent of the houses. In the multistory houses, the POF backbone’s performance enhancement reached over 560 percent, whereas Wi-Fi only had a reduced output of up to 62 Mbps. Despite the limited number of Wi-Fi end points used in the test, the numbers provided by the Wi-Fi backbone fall far short of the access speeds users have started to enjoy up to their homes. By using the same Wi-Fi Mesh nodes with a POF backbone, the end user experience achieves those numbers. End users experience what they pay for. 

Another important result was that with only one more access point with POF as the backbone, performance is significantly better sustained than with two additional access points with a Wi-Fi backbone. POF Backbone simplifies the Wi-Fi mesh architecture and reduces costs while improving overall performance substantially. 

KDPOF will present their robust in-wall optical connectivity at stand 3 at Broadband Forum Asia on May 7-8, 2019 in Bangkok, Thailand. In his presentation “Bringing WiFi Performance to the Next Level” on 7 May at 12:20, Ramón Garcia, Business Development Manager with KDPOF, will explain options and good practices for how to transform access speeds into Wi-Fi speeds for a Gigabit experience.

Demo showing robustness of automotive gigabit over POF

At the recent Automotive Ethernet Congress in Munich, Germany, KDPOF presented the innovative Automotive Gigabit Ethernet Plastic Optical Fiber (GEPOF). “We are delighted by the great interested we received for our POF technology that secures new 48-volt electrical architectures via the inherent galvanic isolation,” stated Carlos Pardo, CEO and Co-founder of KDPOF. Optical connections with POF provide the optimal network to achieve galvanic isolation, providing 100 Mbps and 1 Gbps Ethernet compatible solutions with enough margin to withstand the harsh automotive environment. Applications such as Battery Management Systems (BMS) and Integrated Smart Antenna (ISA) modules profit from the inherent Electromagnetic Compatibility (EMC) of POF.

Future-ready: KDPOF automotive Gigabit Ethernet provides electromagnetic compatibility, robustness, and smooth integration

KDPOF – leading supplier for gigabit transceivers over POF (Plastic Optical Fiber) – will present automotive Gigabit Ethernet POF (GEPOF) for future wire harness architectures at stand 18 at the 7th International Conference Automotive Wire Harness on March 26 and 27, 2019 in Ludwigsburg, Germany. “With its inherent galvanic isolation and robustness, the optical Ethernet technology ideally suits current and future in-vehicle network infrastructure,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “POF lives up to the challenges of electromagnetic compatibility and safety requirements created by the new 48-volt electrical architecture.” A well-supplied and competitive market worldwide ensures seamless integration into the wire harness of the vehicle. The inherent Electromagnetic Compatibility (EMC) makes POF perfectly suitable for applications such as Battery Management Systems (BMS) and Integrated Smart Antenna (ISA) modules. Autonomous driving relies on POF for a redundant system in addition to copper cabling in order to increase safety and avoid the autonomous car locking up if one of the systems is disturbed in some way.

KDPOF Automotive Gigabit Ethernet Provides Electromagnetic Compatibility, Robustness, and Smooth Integration

POF cables are very reliable: they can withstand harsh environments, vibrations, and misalignments. In addition, POF allows fast dynamic bending, tight bending, and dark liquid immersion in addition to delivering low noise and robustness regarding in-coupling of electromagnetic fields. As a plastic, wide diameter fiber, POF is cheap to manufacture and install: installation is just easy plug and play; winding and clamping is similar to copper cables. With the first automotive Gigabit Ethernet POF transceiver KD1053, KDPOF provides high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver complies with the standard amendment IEEE Std 802.3bv™ and thus fully meets the requirements of carmakers.

KDPOF's optical data network enhances safety for autonomous driving

KDPOF provide their optical network technology in order to enhance safety for autonomous driving. “For safety-related functions such as the data network backbone, autonomous driving requires redundant systems in order to increase safety and avoid the autonomous car locking up if one of the systems is disabled in some way,” explained Rubén Pérez de Aranda, CTO and Co-founder of KDPOF. Reliability analysis shows that a technology redundancy like optical and copper cabling provides the highest reliability. Consequently, more and more OEMs are now considering Plastic Optical Fiber.

EMC Lessons Learned on Gigabit Ethernet Implementation for ADAS & AV

The lessons learned in the iterative design process give KDPOF the knowledge to bring into the market a mass-produced automotive Gigabit Ethernet PHY integrated in an ECU and meeting the most stringent EMC specifications. “This grows more important as in-car network speeds increase to accommodate the demands of driverless systems,” he added. “Higher speeds are achieved by wider use of the electromagnetic spectrum.”

This situation makes the underlying communication system implementation less immune to radiated and conducted noise. It also forces OEMs to impose more and more stringent emissions limits on the electronic components, limits that are often already tighter than the demands imposed by international standards. POF is ideal for the new architectures since it provides natural galvanic isolation between communicating modules and a radiation-free harness.

With the first automotive Gigabit Ethernet POF (GEPOF) transceiver KD1053, KDPOF provides high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. The transceiver complies with the standard amendment IEEE Std 802.3bv™ and thus fully meets the requirements of carmakers.

KDPOF displays optical connectivity providing galvanic isolation for Battery Management Systems and Smart Antenna Modules at Automotive Ethernet Congress

At Automotive Ethernet Congress on 13 and 14 February 2019 in Munich, Germany, KDPOF will display their optical connectivity technology in order to secure new 48-volt electrical architectures via the inherent galvanic isolation. Optical connections with POF, such as KDPOF’s innovative Automotive Gigabit Ethernet POF (GEPOF), provide the optimal means to achieve galvanic isolation, providing 100 Mbps and 1 Gbps Ethernet compatible solutions with enough margin to withstand the harsh automotive environment. Applications such as Battery Management Systems (BMS) and Integrated Smart Antenna (ISA) modules profit from the inherent Electromagnetic Compatibility (EMC) of POF. “The new 48-volt electrical architecture pushes the envelope in terms of electromagnetic compatibility and safety requirements,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “New safety precautions are needed, since even a single malfunction between the 48-volt and the 12-volt electrical system will lead to a short circuit, which can damage the entire 12-volt system due to overvoltage.” 

We look forward to meeting you in Munich. For arranging a meeting, please contact Óscar Ciordia.

KDPOF presented guaranteed Wi-Fi Mesh up to 1 Gigabit/s with robust, low latency POF backbone at Broadband World Forum 2018

The team at KDPOF is delighted by the great interest at the Broadband World Forum recently in Berlin where they publicly premiered their Plastic Optical Fiber (POF) backbone to guarantee 1 Gigabit/s Wi-Fi Mesh for home and SOHO networks. “In combination with Wi-Fi access points, POF provides end users with maximum performance for both wireless and wired connectivity throughout the house,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “POF can reuse any existing conduits in the home, making these cables invisible.” Plastic Optical Fiber is cost-efficient, low skill to install, and robust. In addition, it provides convenient Optical Network Termination (ONT) to Gateway (GW) link for a better placement of the GW within the home. By working with KDPOF, operators can offer their clients low latency, fast download speeds, and reliable connectivity for video with the ability to match access speeds and integrate with existing Wi-Fi Mesh solutions.

A field trial by KDPOF and Telefónica to test the benefits of POF has demonstrated that KDPOF’s technology helps to provide subscribers with very high sustained connectivity speeds from 100 Mbps onwards all around the home, levels that both wireless or powerline as backbone for Wi-Fi Mesh devices cannot reach. Thus, it allows users to enjoy high-quality video streaming such as 4K IPTV, and supporting services such as online gaming with the lowest latency. Accordingly, the combination of Wi-Fi with Plastic Optical Fiber can increase Quality of Experience dramatically, leading to a surge in customer loyalty.

KDPOF speeds up home networking with POF backbone for higher Quality of Experience

At Broadband World Forum in Berlin, Germany, KDPOF will present their robust in-wall wired optical connectivity from October 23 to 25, 2018 at Stand A133 in Hall 22a. “With our Plastic Optical Fiber backbone, we elevate Wi-Fi EasyMesh(TM) performance to the next level: from more than 100 Mbps up to 1 Gigabit to any point in homes and small and home offices,” stated Carlos Pardo, CEO and Co-Founder of KDPOF. In combination with Wi-Fi access points, POF provides end users with maximum performance for both wireless and wired connectivity throughout the house. POF can reuse any existing conduits in the home, making these cables invisible. Plastic Optical Fiber is cost-efficient, low skill to install, and robust. In addition, it provides convenient Optical Network Termination (ONT) to Gateway (GW) link for a better placement of the GW within the home. By working with KDPOF, operators can offer their clients low latency, fast download speeds, and reliable connectivity for video.

Quality of Experience

“ISPs and Telecom operators are facing the paradox that while access speeds have increased, customer satisfaction rates drop if home networks cannot keep up,” added Carlos Pardo. Access speeds are growing higher and higher while users at home are locally connecting more and more devices to the internet. Customers expect to experience the speeds they are paying for. If these speeds are lower than expected, they are disappointed and the Quality of Experience declines. A trial of KDPOF and Telefónica to test the benefits of POF has resulted in the outcome that KDPOF’s technology helps to provide subscribers with very high connectivity speeds all around the home, allowing users to enjoy high-quality video streaming such as 4K IPTV, and supporting services such as online gaming with the lowest latency. Thus, the combination of Wi-Fi with Plastic Optical Fiber can increase Quality of Experience dramatically, leading to a surge in customer loyalty.
