a. The TIA 568 building wiring standard specifies 160/500 MHz*km MMF (Multi-mode
Fiber).
b. The international ISO/IEC 11801 building wiring standard specifies 200/500
MHz*km MMF.
c. The ANSI Fibre Channel specification specifies 500/500 MHz*km 50 micron MMF
and 500/500 MHz*km fiber has been proposed for addition to ISO/IEC 11801.
NOTE: Cable installation and network configuration will affect overall transmission capability. The numbers
provided above represent the accepted recommendations of the various standards. For network-specific
recommendations, consult your local Foundry reseller or system engineer.
