This cable was shipped as promised and arrived in time for install

This cable was delayed but when I called and said I needed it right away for an emergency. It was shipped that day and arrived the next. Very glad for such a prompt response.

It was my first time buying on FS.COM because I never heard FS before until one of my working partners suggested this website. At first, I was a little worried about the quality. But when I got these cables and placed them on racks, they really impressed me. You guys really did a good job! I have bookmarked your website for further needs. Certainly, I will recommend you to my fellows.

Not much else I can say but it’s a great DAC breakout cable. I ordered four sets and used them on my Cisco Nexus 92160YC-X switch. All of them worked flawlessly and had no compatibility issues.

The team was very professional and helpful. In the beginning, we gave them wrong information. We told them we planned to make connections between 100G Cisco Nexus switch and Cisco 5501, and we thought the 100G to 4x 25G DAC was a good choice. The team checked our device’s datasheet and told us that Cisco 5501 didn’t support 4x 25G connections. We realized that we made a mistake. Actually, 100G to 25G connections would be implemented on our Cisco Nexus and 25G Intel adapters. The guy confirmed the compatibility, then we made the order. Really appreciated their precise work and had no hesitation in recommending this professional team.

The DAC cables were protected well when I received them. Now, they are recognized by my Mellanox devices and do 100G link, 0 dropped packets.

I have these breakout cables to connect my 25g and 100g switches. They work immediately after inserting it. Quality seems good and costs less than my expectations. Would buy more here.

At first, I only bought one cable for test as I have never ordered in FS. But the results proved I worried too much, it works very well and then I buy 20 more for my projects. Shipping was very fast and they are now all working normally in the switch racks.

I got a 1M and 2M 100G to 4×25G cables. I have these connected into 25G Mellanox Connect4-x Nics and Mellanox 2100 100G switch. The cables work perfectly with both devices and were seen immediately. Seems to be good quality build of cables and performs as advertised.

We are looking for a cable to connect Cisco N9K-C93180YC-EX and Mellanox 4421/4121A-ACAT cards. The 100G QSFP28 to 4x25G SFP28 DAC breakout cables we finally got were priced very competitively and worked exactly as intended. Considering that there will be the needs to work these cables on other switches like Mellanox SN2700/SN2100, Cisco, Arista, Juniper, etc that can do the 100G QSFP or 25G QSFP connections, we turn to the FS box which we have been eyeing for some time now. The AM has helped confirm that it can do the coding of the 100G QSFP28 side of the breakout DAC cable. With it, the 100G side of the 100 to 4x25G DAC cable is able to go to any switch. Would like to share more about the use of FS box (maybe an UNBOXING video on YouTube) later on.
