DAC (direct attach copper) cable systems for QSFP56 interfaces

Our QSFP56 or 200 GBASE-CR4 copper cables are the low-power, low-latency and hot-pluggable solution for 200 Gbit/s high speed interconnections of servers, routers, switches and storage systems. They conform with the IEEE 802.3 cd specification and support 200 Gbit/s Ethernet over at least 3 m (10 ft) of copper with channel rates of 4 x 50 Gbit/s.

We provide QSFP56 DAC cables in AWG sizes 26, 28, 30 and 32. In addition to PVC versions, the assemblies are available with halogen or lead-free unique elastomer outer jackets and certified according to UL 13 CL2 in compliance with CSA FT4.
