The layer is ideal for high-bit-rate data streaming used in driver assistance systems, for connecting mobile devices as well as for multimedia applications in vehicles.

These parallel applications require high data throughput using a simple, lightweight and inexpensive copper cable, combined with low power consumption and minimum latency. Fraunhofer IIS has developed this core technology for the next generation of data transmission and is in the process of making it ready for production.

Consuming less than one watt for every transmitter/receiver pair, the physical layer can transmit 10 Gbit/s over a single twisted pair cable 10–15 meters long. Keeping the latency to a minimum provides video data for human-machine interaction tasks in real time. The universal design of this development allows a wide range of content with various requirements to be transmitted simultaneously, which also means that connections that used to run in parallel can now be consolidated into one pair of wires.

The developed physical layer is currently working at 10 Gbit/s. For further applications it is intended to increase the data rate to 12.5 Gbit/s. This will serve as core technology for virtually all common data rates of 10 Gbit/s and more.

High-speed data transmission systems are by no means limited to a vehicle’s on-board electronics. Many other application areas have similar requirements. These areas include industrial facilities, mechanical and systems engineering, automation technology, medical technology, robotics and data centers. Broadcasting that uses multiple cameras and HD or even 4k video streaming can also benefit from this technology.
