Ethernet networks are the most common type of networks in existence today. Glass fiber
optic cable is used for the long distance runs and for very high speed connections. In
this network, cross connections between walls and computers, patch panels and equipment,
or between two pieces of equipment use jumper cables. This jumper cable is a 9/125 glass
fiber with LC connectors on both ends. The different Ethernet types that use fiber are 10
Megabit per second Ethernet (10Base-FL), 100 Megabit per second fast Ethernet (100Base-FX)
and 1 Gigabit per second gigabit Ethernet (1000Base-FX, 1000Base-SX or 1000Base-LX).
