PRODUCT DESCRIPTION
D-Link DEM-CB700S 10G Passive SFP+ Twinaxial Direct Attach Cable, 7 m (DEM-CB700S) - 5 Years Local Warranty
The Longest 10G DAC in the Range
The D-Link DEM-CB700S is a 7 m passive twinaxial direct attach copper (DAC) cable with an SFP+ connector on each end, carrying 10 Gbps Ethernet between two SFP+ ports — long enough to run between racks in a row without optics or fibre patching.
Heavier 24 AWG Conductors
To cover 7 m the DEM-CB700S uses 24 AWG twinax (the 1 m and 3 m models use 30 AWG), with 100 Ohm impedance and a 23.5 mm minimum bend radius. It is compliant with the SFP MSA, SFF-8431, EIA 364 and UL 94 and rated for -40 to 85 °C.
