2-Pack 1.5m/4.92ft 10Gb Direct Attach Copper Cable, SFP+ Passive Twinax DAC Cable for Cisco SFP-H10GB-CU1.5M, Ubiquiti, Arista, D-Link, Huawei, Intel, Meraki, Mikrotik, Netgear, TP-Link etc.

What can I say? It came just as described and worked when I plugged it in.

The 2-Pack 1.5m/4.92ft 10Gb Direct Attach Copper (DAC) Twinax Cables are a stellar addition to my home networking setup! These SFP+ to SFP+ passive cables deliver blazing-fast 10Gbps Ethernet speeds, perfect for connecting my Ubiquiti UniFi switch to my NAS with a Mellanox Connect-X 3 card. The 1.5-meter length is ideal, offering enough flexibility to route neatly within my rack without excess slack. Made with 30AWG copper twinax, these cables ensure low latency and zero power consumption, making them a cost-effective alternative to fiber optics for short-distance connections. Setup was plug-and-play—both cables were instantly recognized by my devices without any configuration, achieving full 10Gb throughput with no dropped packets. The build quality is top-notch, with sturdy zinc-alloy connectors that provide excellent heat dissipation and EMI resistance. I’ve run iperf tests, and the performance is flawless, matching pricier branded cables like Cisco or Ubiquiti. The two-pack is a great value, allowing me to connect multiple devices in my rack seamlessly. My only minor note is that the cables are slightly stiff, which can make tight bends tricky, but this is typical for DAC cables and doesn’t affect performance. Compared to fiber or Cat6a solutions, these DACs are simpler and more reliable for my server room. For anyone needing high-speed, dependable connections in a data center or home lab, these cables are an outstanding choice! Highly recommend!

I purchased this DAC cable for use between my unRAID server and my network switch. It is connected to an Intel X710-DA2 card's SFP+ port and it auto-negotiates to 10GbE as expected. The quality appears to be good. I did not notice any defects and it functions as I expected. The length is as described, and is flexible enough to maneuver around as required. The color is as shown in the picture. From what I can tell, the compatibility is good and I had no issues with incompatibility so far. Overall, I would purchase these cables again. Since I have a two pack, I will likely get another SFP+ card 10GbE card for my desktop to a different switch. If I encounter incompatibility, I will update my review. But I don't expect any issues based on my previous testing.

I bought two of these DACs and they were a great value for the quality, and ease of use. Connected them from my switch to my home servers with no issue, and they both connected at full speed. File transfers across my network now are super fast! These perform great!

Installed with no issues, getting 10GB throughput on it. Cable is top quality and doesn’t feel like a cheap product. Cord length is spot on and have bought more due to excellent cost.
