What is the difference Among OM1, OM2, OM3, OM4 and OM5

Multimode fibers are identified by the OM (“optical mode”) designation as outlined in the ISO/IEC 11801 standard. OM1, for fiber with 200/500MHz*km overfilled launch (OFL) bandwidth at 850/1300nm (typically 62.5/125um fiber) OM2, Type A1a.1 , for fiber with 500/500MHz*km OFL bandwidth at 850/1300nm (typically 50/125um fiber) OM3, Type A1a.2, for laser-optimized 50um fiber having 2GHz*km […]
