Fiber Types and Typical Specifications
50/125 microns (OM2, G.651.1)
Laser-rated for GbE LANs
50/125 microns (OM3, G.651.1)
Optimized for 850 nm VCSELs
50/125 microns (OM4, G.651.1)
Optimized for 850 nm VCSELs, higher speed
50/125 microns (OM5)
Wideband MMF, optimized for WDM 850-950 nm VCSELs, higher speed
62.5/125 microns (OM1)
9/125 microns (OS1 B1.1 or G.652)
Singlemode fiber, most common for Telco/CATV/high speed LANs. OS1 is a designation of TIA-568 for SM fiber cabled for premises use that has higher attenuation - 1dB/km. All SM fiber appears to be low water peak fiber.
9/125 microns (OS2, B1.2 or G.652)
Low water peak fiber. OS2 is a designation of TIA-568 for SM fiber cabled for outdoor use.
9/125 microns (B2 or G.653)
Dispersion shifted fiber
9/125 microns (B1.2 or G.654)
Cutoff shifted fiber
9/125 microns (B4 or G.655)
Non-zero dispersion shifted fiber
9/125 microns (G.657)

Some standards now include attenuation at 1383nm (water peak) which is generally no higher than at 1310nm.
CAUTION: You cannot mix and match fibers! Trying to connect singlemode to multimode fiber can cause 20 dB loss - that's 99% of the power. Even connections between 62.5/125 and 50/125 can cause loss of 3 dB or more - over half the power.
The usual fiber specifications are size (core/cladding diameter in microns), attenuation coefficient (dB/km at appropriate wavelengths) and bandwidth (MHz-km) for multimode fiber and chromatic and polarization-mode dispersion for singlemode fiber. While manufacturers have other specs for designing and manufacturing the fiber to industry standards, like numerical aperture (the acceptance angle of light into the fiber), ovality (how round the fiber is), concentricity of the core and cladding, etc., these specs do not generally affect users who specify fibers for purchase or installation.
