Typically, OM3 fiber is used for 10G Ethernet and can make connections up to 220 meters long. However, it can also be used for 25G Ethernet connections up to 70 meters long and 40G/100G

OM3 supports distances of 1000m for 1 Gbps, 300m for 10 Gbps and 100m for 40/100 Gbps. OM4 supports distances of 1000m for 1 Gbps, 550m for 10 Gbps and 150m for 40/100 Gbps.

So multimode fiber is suitable for short haul application, allowing transmission distances of up to about 550m at 10Git/s. When distance is beyond 550m, single mode fiber is preferred.
