Netgear Direct Attach SFP+ Kabel ProSafe - - 10 Gigabit Ethernet Connectiviteit - 3m

These cables appeared to be high quality, unfortunately I had to return them because they are incompatible with the Cisco hardware. I don't think its a physical compatibility issue as much as it is an issue with the validation that Cisco hardware does before it will operate with a cable. The cable has some kind of micro-controller embedded in it that returns some kind of information on certifications of the cable. Cisco apparently will not use cables that don't have certain certifications reported. So I can't say if the cable works wonderfully with other hardware, it just does not work with the Cisco switches I've tried.
