SFP+ Cable 15m

Hello,

I am looking at purchasing a 4x 10GB 15m SFP+ to SFP+ cables to go between our 6800 and 3850 switches

I have been warned about issues going above 10m cables for SFP+ cables? does anyone user 10m plus active cables or had issues?

I am not sure if I can allowed to paste links to where I am google searching but ill give it a go so you can see the item description - they also do unto 30m but its whether I am going to hit any issues?

just want some further acknowledgement and he was told by someone from someone by someone so unsure how real the comment is
