had all multimode fibers under G.651.1
OM1 is legacy 62.5/125 micron multimode fiber standardized for data by IBM in the mid 1980s, adopted by FDDI in the late 1980s and standardized for TIA-568 in the early versions of the premises cabling standard.
OM2 is legacy 50/125 micron multimode fiber standardized for data for gigabit multimode networks in the late 1990s in TIA-568.
OM3 and OM4 are higher bandwidth versions of 50/125 fiber used for faster data networks and for longer distance links.
OM5 is a wideband 50/125
micron multimode fiber standardized for use with short
wavelength WDM with VCSEL sources in the range of 850-950nm.
Here is more information on the nomenclature and use of multimode fibers.
Color Codes
Fiber types are
identified by color codes for cable jackets and/or connectors.
