Can an LTM be connected to a Cisco FEX (fabric extender)?

I have them connected to a pair of 7010's. (SUP1's, Fabric 1 and M132 XL cards).

The Optics I use at the 7010 end of the links are Cisco 10-GB-SR's. FET's probably don't work (I'm not sure of their tx/rx or freq). FET's are basically good for FEX's and FIC connectivity. (Possibly other cisco switch-switch links as well).
