Mixing cables

Can you intermix the use of 62.5 micron and 50 micron MM SC-SC Fiber Optic cables? Does this pose any signaling problems?
Different sized cables can be mixed in the same SAN, but not on any single link. This depends on the configuration capabilities of the equipment. For instance, a switch vendor might not support or sell such a configuration. In general, it makes sense to keep them the same for the sake of sparing. You don't want to have to keep spare parts for both types of cables. It could cause confusion and headaches later.
