H!Fiber SFP+ Cable, 10G SFP+ DAC, 0.5M(1.64ft), Passive Direct Attach Copper Twinax Cable for Cisco SFP-H10GB-CU0.5M, Ubiquiti UniFi UC-DAC-SFP+, Meraki, Mikrotik, Intel, Fortinet, Netgear, 0.25m-7m

I’m using this cable between my QNAP NAS and a switch, and it was recognized immediately. All devices report the link as 10Gb, and the connection has been stable with no drops or errors. I’m including a photo showing the interface registering at 10Gb. The 1-meter length was exactly what I needed for a short connection between devices. It keeps things clean without extra slack, and the cable itself feels solid and well made. I don’t currently have another device that can fully take advantage of 10Gb speeds, so I haven’t been able to do real-world throughput testing yet. That said, everything detects the cable correctly, negotiates at full speed, and behaves the way a proper SFP+ DAC should. One thing to note is that the connectors fit very tightly. Unplugging it takes some effort, and the release tab feels stiff enough that I’m careful when removing it. It hasn’t caused any issues, just something to be aware of. For a short SFP+ connection where you want something that’s recognized correctly and works without configuration, this cable has done what I needed so far and leaves room for future upgrades.

Works great with legacy unify switch and unify 16 port Poe switch. Legacy switch has 1gb sfp and new unify has 10gb sfp. Links right up at 1gb as expected. No config needed. Great alternative to name brand product.

I wanted to connect a 2.5gb/s switch into my gb switch and needed an SFP solution to provide the best throughput possible. This DAC (direct attach copper) solution provided exactly what I needed at an incredibly reasonable price. Now I have a 10gb/s connection between my switches for less than $10! That is less than the price of most SFP's! What a great value for the money. I am very happy with my purchase. The only downside is your switches need to be very close since this cable is so short, but otherwise what a great solution. Just plug it in and it works!

This is an excellent product, delivered on time, and which works perfectly as advertised.

Very good performance. No issues with Ubiquity and Mikrotic switch.

Arrive on time and worked in ubiiqiti switch

Perfect length for a mobile rack and profession where we need a mobile solution. Used in a unifi system that packs up into a mobile office. I did have to manually set 10GB between the gear but other than that worked well. Would not auto 10GB.

Great connection speed between my gig switch and POE switch. Works very well. Very happy with this purchase!
