Never tried on a 7k but you should be ok, everything else I've tried works fine.
Talk to your vendor, most will code the sfp+ to whatever you want to make it compatible, even suggesting what is best.
i.e. the 7k thinks it's a SFP-10G-LR but in reality it's  cwdm. ( you can check what they show up as on the 6500 with sh inv)
We use solid optics and have been happy with the product and support.
As to if it's officially supported,  that is another can of worms.
