Works like a charm! Gotta say the quality of both packaging and the cable feels higher quality than OEM. Nice with the included Velcro ties also to make cable management easy also. Worked flawlessly on a MX9116 switch connected to Intel XXV710s.

Excellent product and superfast delivery !

Cable worked perfectly!!

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.

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

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.
