HPE H3C Compatible Direct Attach Cables SFP+ To SFP+ Copper Twinax DAC 1M
HPE H3C Compatible 10G SFP+ Passive Direct Attach Copper Twinax Cable 1M
The DAC SFP+ cable assemblies are high-performance, cost effective I/O solutions for 10Gb Ethernet and 10G Fibre Channel applications. SFP+ copper modules allow hardware manufacturers to achieve high port density, configurability and utilization at a very low cost and to reduce power budget. The high-speed cable assemblies meet and exceed the performance and reliability requirements stipulated by Gigabit Ethernet and Fibre Channel industry standard.
