This cable worked with my Intel XXV 25G card and Mikrotik CRS510 switch out of the box. They auto negotiated the link down to 10G instantly. I didn't have to reprogram the cable to Intel/Mikrotik, saving me time. I'm glad I ordered the generic version. It was affordable as well especially for the length. I received the product in less than 3 days even though shipping was free.

Works well. I had to manually set the link speed to 10gbps on a native sfp28 to get it to properly connect to an SFP+ port on the other side, I was expecting some sort of auto-negotiation, but that could be the switch's fault.
