[General] What are the distance limitations of Gigabit Ethernet?

Notes:
1. The TIA 568 building wiring standard specifies 160/500 MHz*km multimode fiber
2. The international ISO/IEC 11801 building wiring standard specifies 200/500 MHz*km multimode fiber
3. The ANSI Fibre Channel specification specifies 500/500 MHz*km 50 micron multimode fiber and 500/500 MHz*km fiber has been proposed for addition to ISO/IEC 11801.
