hey Alex I've used fs.com tranceivers extensively, as others have said, and as long as you get them coded correctly (specify your vendor when ordering), they're pretty good.
With Vocus, I have found that the stated length of the DF link is often - well, understated. So your 11k link could quite likely end up being 12 or 13 (I had one which was listed in all Vocus' documentation and testing reports as 37k's - could not, for the life of me, get a 10Gb-ER tranceiver working on the link with an acceptable loss - had to go to a ZR to bring the link up). I'd recommend you stick ER tranceivers in this link (good for up to 40k's) - and probably go 1550nm rather than 1310. FS has heaps of them, and they're not anywhere near as expensive as genuine Cisco ones. You can try a pair of LR's for shits and giggles (they're only about $40 each), but I'd almost bet they won't work unless you're very luck with the number of joints in the link and the insertion loss levels. You *might* need a 3dB attenuator on each end - but they'll sell you those too - and if your receive power isn't above the limit, you can get away with removing it. One thing to note is that if you use a non-genuine transceiver and have to log a TAC case, Cisco will immediately tell you so sod off when you log it because it's not "supported" - so it comestimes pays to keep a genuine one on hand to swap into the switch in case you have an issue - but if it's only one link, it's debatable if it's worth doing that - keep a couple of spare FS ones in case they go bad. D P.S. I am not affiliated in any way with fs.com - just a satisified customer.
