Singlemode Singlemode 9/125
Singlemode optical fiber designated by the TIA as OS1. Singlemode fiber has a core size of 8 – 10 microns with a cladding size of 125 microns. Designed for long distance transmission (10km or more) of data with a laser driven system.
 
Singlemode Multimode 62.5/125
Multimode fiber designated by the TIA as OM1. 62.5/125 fiber has a core size of 62.5 microns with a cladding size of 125 microns. Rated for data transmission of 10Mb – 1Gb per second. Mostly used in optical networks spanning short distances (1Gb/s at 850nm for 300m). Largely used with LED based transmission equipment.
 
Singlemode Multimode 50/125 Standard
Multimode fiber designated by the TIA as OM2. 50/125 fiber has a core size of 50 microns with a cladding size of 125 microns. Rated for data transmission of 10Mb – 1Gb per second. Mostly used in optical networks spanning short distances (1Gb/s at 850nm for 600m). Largely used with LED based transmission equipment.
 
Singlemode Multimode 50/125 10 Gig (OM3/OM4)
Multimode fiber designated by the TIAA as OM3 or OM4. 50/125 fiber has a core size of 50 microns with a 125 micron cladding. Also known as 10 Gig fiber or Laser Optimized Fiber, OM3/OM4 fiber has been designed to interface with laser data transmission systems with performance specified as up to 10 Gigabytes/second. Backwards compatible with Multimode 50/125 Standard OM2.
