Make sure to look at the length chart

Reviewed in the United States on April 5, 2024

Size: 0.25mColor: 10GNumber of Items: 1Verified Purchase

First time DAC purchase and I was caught off guard by the length of the cable since the DAC enclosures take up a good portion of the cable. I had thought these were longer than 6" patch cables and there would be more usable length but that is not the case. This was my error though, and learn from my mistake by making sure to check the image showing the length of the cables in comparison to the rack. I fortunately lucked out and bought the shortest cable and only needed to go 1U so the chart was true to size.

Outside of that, this so far has worked flawlessly. I used it to connect my UDM-SE and USW-Pro Max from Unifi/Ubiquity. The devices are showing full 10G connection.

Since this is my first dive into any fiber cables / transceivers I don't have a lot I feel I can add about the quality and features of this cable. As far as I'm concerned it was easy to install and is working as advertised. I plan to purchase more from this vendor in the future if my stack continues to grow!

An inexpensive way to connect at 10Gig

Reviewed in the United States on March 3, 2024

Size: 2mColor: 10GNumber of Items: 1Verified Purchase

I wanted to connect two NAS devices to my switch and this turned out to be less expensive that a fiber patch cables plus the GBICs. Since the devices were all close together it was the right choice.

It seems sturdy and it was immediately recognized by the QNAP and Ubiquity equipment.

Working now. Great customer service.

Reviewed in the United States on December 7, 2023

Size: 0.3mColor: 10GNumber of Items: 1Verified Purchase

Edited: I had an issue using these cables (see below). After posted the review about them, I was contacted by the manufacturer, and offered a refund, as well as an apology and some suggestions for testing and/or returning the items. Customer service was great.

It was suggested that I could use one cable at a time to see if the issue was the result of one cable or a combination of them. Customer service was so nice, I figured I'd go ahead and do the testing. Heck, I liked the short DAC cables, so if only one was bad, I'd prefer to just replace that.

Well, after a bunch of testing, I could not reproduce the issue I was getting in the first place. I'm not sure if a change in my network made the issue go away, but I'm now using the three cables I bought, and they're working great. I am grateful that customer service was so polite and patient with me.

Previous review:
I had three of the 0.3m 10G DAC cables in my network. I had one connecting my UDM-Pro (router) to a USW-Pro-Aggregation switch, and two (in aggregation) connecting the USW-Pro-Aggregation to a USW-Enterprise-24-PoE switch.

With these cables, the connection speed was incredibly inconsistent. Sometimes I'd get line speeds, but the upload speed from a device on the PoE switch to the internet (2gig symmetrical fiber) would regularly drop to as low as 35 Mbit/s.

Took me forever to figure out what was causing it, but when I swapped out these three cables for Ubiquiti branded ones, problem solved.

I only caught this issue because I setup a VM to monitor my internet speed by recording internet speedtest results every 15 minutes or so. I've had ISP problems in the past, so I do this out of habit.

10Gtek SFP+ DAC Twinax Cable - A Must-Have Upgrade for Your Network

Reviewed in the United States on November 12, 2023

Size: 1mColor: 10GNumber of Items: 1Verified Purchase

I recently upgraded my network infrastructure to support 10GB data transfer speeds. As part of this upgrade, I needed to replace my existing SFP+ cables with new ones that could handle the increased bandwidth. After researching different options, I decided to go with the 10Gtek SFP+ DAC Twinax Cable.

I am very happy with this decision. The 10Gtek cable is a high-quality product that is easy to install and use. It has exceeded my expectations in terms of performance and reliability. I have not experienced any dropped packets or errors since installing the cable.

In addition to its performance, I am also impressed with the build quality of the 10Gtek cable. The cable is well-made and feels durable. It is also very flexible, which makes it easy to route through tight spaces.

Overall, I highly recommend the 10Gtek SFP+ DAC Twinax Cable to anyone who needs a high-performance, reliable cable for their 10GB network.

Pros:

High-performance
Reliable
Easy to install and use
Durable
Flexible
Cons:

None that I have found

Perfect cables for Intel NICs

Reviewed in the United States on October 8, 2023

Size: 2mColor: 10GNumber of Items: 10Verified Purchase

I used these to build out a field lab built on Dell R720s and a combo of Intel and Mellanox NICs. Intel NICs can be picky with non OEM optics but will always work with a DAC cable. Performance with DAC was the sames a optic plus a Om3 LC toLC multi mode fiber optic cable. I think DAC cables are less stressful to work with vs optical cables.

Compatible with Intel x520 DA NICs
Compatible with Mellanox Connect-2/3 NICs

Works great!

Size: 0.5mColor: 1GNumber of Items: 1Verified Purchase

I had 3 POE IP switches with SPF ports that I didn't use. After running out of port space and almost adding another switch I looked up what this port was. This cable worked amazing I connected all switches together with a port I never thought I would use freeing up 4 regular ports in the process. For the home user with multiple cameras as a hobby you might not consider this but it works well and you won't complain.
