6COM 10G SFP+ DAC Cable, 3 M (10ft) Passive Twinax Cable, Direct Attach Copper, SFP+ to SFP+, 10GBASE-CU Cable for Cisco, Ubiquiti, D-Link, Supermicro, Netgear, 3 Meter

This DAC 10Gbs cable for SFP+ worked very well for the switches and NICs I've tested it with. It gave full speed transfers at 10Gbs without any issues and had a very low latency. Currently using this cable for connecting a workstation to a NAS via iSCSI and it is working perfectly and allowing for fast data transfers faster than having a local SATA SSD HDD.

Everything was as advertised and it arrived in a timely manner. Unless something changes, I currently have no reason to not give it a 5-star rating.

I occasionally have to test network switches at home, and this SFP+ cable makes it easy to do the 10gig port testing. The cable is fairly slim, allowing for airflow and flexibility on cable runs - I can run from a rackmount switch in my home lab through the rack door to my workbench, for example, to run a computer against the switch for testing. I usually don't need active DAC so this provides most of my needs at a very good price.

Ah to DAC or SFP. Well SFP jumper fiber is sometimes easy to break. SFP adapters come in different flavors. If the DAC works with your gear, which some is fussy (Ahem Cisco), then you should be good to go. This DAC linked at 10 Gigabits/s and linked between Intel NICs and Ubiquiti switches. I like the locking of the SFP-end and the ease of removal if needed. For fixed connections that don't need flexibility at 10 Gig a DAC is the way to go for me. If you like more flexibility, at the potential cost of more complexity, then stick to SFPs.

I have been using this cable to do a direct attachment connection between a generic Broadcom based NIC (B06X9T683K) I have in my workstation, connected to a MikroTik switch (B07LFKGP1L) which has four SFP+ ports. The switch is then connected to my home server with the same style of connection. The connectors on the cable click and lock into place smoothly and release smoothly when I tried taking them back out. I am getting excellent performance (10GB) between these two machines and working with large files between them is so much faster than the old 1GB Ethernet connection I had prior to this.
