DAC (direct attach copper) cable systems for SFP56 interfaces

Our SFP56 copper cables are the ideal high speed interconnect for reliable 50 Gbit/s transmission between servers, routers, switches and storage systems in data centers. 10 or 25 Gbit/s DACs can easily be upgraded with SFP56 cables making them a cost-effective alternative for 40 Gbit/s high speed interconnects. Our SFP56 cables conform with the IEEE 802.3cd specification and support 50 Gbit/s Ethernet. 

We provide SFP56 DAC cables in AWG sizes 24, 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.
