About EXTOREL
EXTOLL GmbH was founded in 2011 as a spin-off of the University of Heidelberg. The spin-off process has been significantly supported by the German EXIST program. The core technologies of the company were developed at the chair of computer architecture of Dr. Ulrich Brüning, who is a co-founder. The IP has been transferred to EXTOLL GmbH. The research group has also developed a method for low-cost mass production of high-density Active Optical Cables (HD-AOC). Such HD-AOC enable signal transmission over longer distances than it would be possible with purely electrical interconnects. This IP has been exclusively licensed to EXTOLL GmbH. Consequently, EXTOLL GmbH has developed a complete product solution, necessary for interconnecting clusters with sizes ranging from a few nodes up to 64.000 nodes.
