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