Our high speed cables for data centers currently offer transmission speeds of up to 25 Gb/s per pair, using copper. Requests for longer lengths can be realised using optical engines. Our high speed cables and connector systems (proprietary PCBs) are perfectly harmonised with each other and therefore form a secure cable system for reliable data transmission.
