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.”

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.

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.

Extensive evaluation kit EVK9351AUT from KDPOF eases project start for optical gigabit connectivity in vehicles

KDPOF presents the new extensive evaluation kit EVK9351AUT for a quick and easy project launch of optical gigabit connectivity in vehicles. “Our new EVK9351AUT equips carmakers, suppliers, and test houses to fully evaluate the KDPOF automotive transceivers KD9351 and KD1053 for automotive optical 1000BASE-RHC PHY implementation,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “We thus support our recently announced new integrated KD9351 Fiber Optic Transceiver (FOT) for comprehensive evaluation.”

KDPOF Integrates KD9351 and KD1053 in Extensive Evaluation Kit to Facilitate Project Entry for Safe Backbone and ADAS Sensor Links in Vehicles

The platform provides all the functional and performance evaluation capabilities requested by automotive OEMs, Tier1s, and test houses. It therefore enables product designers to successfully evaluate KDPOF’s technology and shorten the time-to-market. The new KD9351, in combination with the continuing KD1053 IC, cuts the cost for 1 Gb/s optical connectivity by 30 percent, providing competitive pricing for EMC critical or galvanic isolated critical links. Applications include safe Ethernet backbones and sensor links for advanced driver assist systems (ADAS).

Evaluation Kit for 1000BASE-RHC Automotive Bridge

The extensive evaluation kit EVK9351AUT contains 2 EVB9351AUT evaluation boards, 2 evaluation board metal enclosures (optional), 2 1000BASE-T SFP modules, 2 100BASE-TX SFP modules (optional), 1 USB2ALL monitoring box, 1 optical harness, 2 Cat. 5e UTP cables, 2 direct-attach passive SFP twinax cables (optional), as well as user and design documentation.

The evaluation boards can operate at 100 and 1,000 Mb/s. A single version of a board is compatible with multiple headers and harnesses from different manufacturers. The user can plug a standard SFP module into the cage and have media converter functionality supporting Wake-Up & Sleep. Complementary items can be provided, such as optical harness, loopback SFP, or SFP direct-attach passive twinax cable. The board is configured in an EEPROM memory. The provided SDK allows the generation of binaries for different configuration options and flashing of the EEPROM. In addition, control and status of the KD1053 transceiver is accessed through the GUI (included in the SDK), which may be run on a computer connected via a USB2All module. The GUI includes several panels that provide complete access to the KDPOF transceiver, providing information on the link status and its parameters. User and design documentation is included in order to simplify the evaluation and the development of automotive end products based on the two-part numbers.

The EVK9351AUT evaluation kit can be ordered via sales@kdpof.com.
