Hey I've got an ICX 6610 with the proper licences from the guide in the mega thread, and I've also got some ProLabs 10G SFP+ modules that show up as Brocade 57-0000076-01 (10GE LR 10km (SFP +)). I've got a ton of these transceivers and I want to have a 10G link between one of my ICX 6610's and a MikroTik switch. On the Mikrotik switch the optic is transmitting but is not receiving, and the fiber is known good. I also have two ICX 6610's that I have tried to get to uplink on the transceivers as well, but still no luck. I think for some reason the ICX 6610s are not enabling the optics. Here is what show media outputs:

Code:
Port   1/3/1: Type  : 10GE LR 10km (SFP +)
         Vendor: BROCADE              Version: B4 
         Part# : 57-0000076-01        Serial#: M5AJ1828
So the switch sees that the optics are there, and I have set the ports to 10G, yet I can't get the link to come up, and show optic gives a blank output. 10GE LR SFP + modules should work, anyone else run into this before?
