Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A 
specification on optical fiber cabling consists of one recognized cable type 
for horizontal subsytems and two cable types for backbone subsystems

. 

Horizontal

 62.5/125 micron multimode (two fibers per outlet).

Backbone

 62.5/125 micron multimode or single mode.

TIA 568-B will allow the use of 50/125 micron multimode optical fiber in 
both the horizontal and backbone in addition to the types listed above. All 
optical fiber components and installation practices must meet applicable 
building and safety codes.
