This is likely the most cost effective way to link two nearby SFP+ systems to each other at 10GB/s transfer speeds. The cable connectors fit and feature nice strain reliefs. The cable has been working without issues for several months now.
The simplicity of this solution is great and the only limited downside is the length limitations imposed by these passive twinax cables. The lack of a transceiver also reduces power needs, heat produced, and so on. Thus, if your switches are close to each other, I'd take a long look at this solution. The only advantage for fiber I can think of is that fiber may be easier to thread from one cabinet to another, especially if you terminate your own cables.
Appears to be made with high quality materials and is detected and functions with the Intel x520-DA2.
Tested point to point between to x520's and achieved 1.2GBps on sequential transfers (no bridging of the NICs, interrupt moderation off, 9K Jumbo frames enabled, and Receive Side Queuing at 2).
Nice work 10Gtek, thanks for making these quality cables more affordable.
I bought Mellanox switches (and cables) and wanted to connect our Cisco Catalyst 3750-X stack (12.5X firmware) using the C3KX-NM-10G modules. The Mellanox cables would not work and a Cisco TAC case told me to try a different type of cable. We tried the undocumented commands to disable HCL checks on the transceivers but it was still failing. I found these and ordered 4 to test. The part number I searched for and ordered (SFP-H10GB-CU3M) was not the same as what was on the items shipped, but I assumed they were compatible so I tried it. Worked perfectly.
