2m(7ft) 10G SFP+ to SFP+ Twinax Copper Passive DAC Cable (Red) for

Colored SFP+ DAC cables are available NOW!
SFP+ DAC (Direct Attach Copper) passive twinax cable is suitable for very short distances transmission and offers a highly cost-effective and low power solution to connect within racks and across adjacent racks.
SFP+ twinax passive cable allows for a serial data transmission up to 10.3Gb/s, which is a low cost choice for very short reach applications of 10GbE or 1-8G Fiber Channel.
SFP+ DAC which replaces two optical modules and a connectorized optical fiber with a twinaxial copper cable assembly offers the higher density, lower cost, and lower power 10 Gigabit Ethernet solution than other cable types such as 10GBASE-CX4 and CAT6/CAT6A 10GBASE-T.
AWG(American wire gauge), decreasing gauge numbers denote Increasing wire diameters, the transmission will be more longer, 30AWG for 0.5~3 meters application, the price is better than 24AWG Cable.

Notice:

1. When link "Intel NIC" with over 3 meters SFP+ DAC Passive, you need to choose 24AWG, otherwise there will exist instability (1 or 2 meters, 30AWG is ok).
2. When link "Cisco switch" with 5 meters SFP+ DAC Passive, you could also choose 30AWG to save cost (because Cisco has enough compensation in the switch’s chipset ).
3. When link "Aruba (HP Provurve) switch"，the hardware is different with others.
4. The compatible for "Brocade CNA", please choice the Active SFP+ DAC.
