What????? Your original question asked whether their CURRENT switches would work with OM3. I asked you for more information on the switches or GBIC SFP modules before I could answer that. They may have been single mode modules for all we know. You didn't provide enough information.

Next you want to know whether any OM2 fiber product would work with OM3, which is 50 micron fiber. I answered the question! Yes as long as the GBIC SFP modules or whatever device your plugging into supports 50 micron fiber. There are some devices which only transmit over 62.5 micron fiber thereby if you use OM3 it will not work since its 50 mic. So again, if you use a device that is compatible with both 62.5 and 50 micron fiber then you will have no problems.
