There is no such thing as collisions now on ethernet/fiber as we use switches instead of hubs. Each link is full duplex and capable of handing 100% capacity.
However if you basing utilization on 5 minute averages like MRTG, keep in mind that's a 5 minute average and you could be going from frequent 100% utilization to 50% utilization within that 5 minute interval, so 75% utilization could be considered full under those circumstances if you want to avoid dropped packets.
