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.
