Making Fiber Optic Connections

1.Prepare a pair of fiber-optic cables with SC or ST type connectors at both ends.

SC-Type Connector

ST-Type Connector

2.If you are making a connection to a server or workstation, be sure it that has a properly installed 100BASE-FX network interface card. Connect the Rx/Tx jacks on the target device to the Tx/Rx jacks on the switch.

Distance Limit and Power Loss in Fiber Optics - When using fiber optic cabling,

the maximum length between two switches can be up to 2 kilometers. However, you must consider power loss when calculating the actual length of cable that can be used with your system. You can calculate power loss with the following formula:

m = (p dB - i dB) c dB/km
