Worked out of the box like a charm with my 25G Intel XXV710 cards and my Mikrotik CRS510 switch. No reprogramming required. Just make sure to disable auto-negotiation on the 100G port and force all four interfaces to 10G or 25G. Be careful not to twist the thin wires as well.

This product is much cheaper than using fiber patch cables.

The signal quality is excellent, and it has significantly improved the speed and reliability of my network.

despite initial concerns with a breakout cable not performing as needed we implemented these into production and have not looked back, great way to take a 100GB port and make 4 x 25GB quickly.

What is the length of the breakout for 30M cable? That is from the point where the trunk cable fans out to the individual transceivers.

Not my first purchase from FS. I bought several 100G QSFP28 to 4x25G SFP28 AOC cables used for splitting 100G to 25G this time. The AM was always ready to give me quick responses. Supportive enough. The packages are sealed solidly. And the products are high-quality as expected. Praise to your first-class services again.

These cables are a great value for splitting 100G to 25G. The cables seemed to be of good build quality. Firmly suited our devices’ ports, zero packet lost during the transmission.
