Fiber Optic Devices

An optional slide-in 100BASE-FX module or 1000BASE-LX SFP transceiver may be
used for backbone or remote connections. A 1000BASE-SX or 100BASE-LX SFP
transceiver may also be for connecting to a high-speed server.
Each single-mode fiber optic port requires 9/125 micron single-mode fiber optic
cabling with an SC or LC connector at both ends. Each multimode fiber optic port
requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC or LC
connector at both ends.
Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are
compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.
1. Remove and keep the SC port's rubber plug. When not connected to a fiber
cable, the rubber plug should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.
3. Connect one end of the cable to the SC or LC port on the switch and the other
end to the port on the other device. Since SC and LC connectors are keyed, the
cable can be attached in only one orientation.

4. As a connection is made, check the green Link LED on the switch
corresponding to the port to be sure that the connection is valid.
The 100BASE-FX fiber optic ports operate only at 100 Mbps, full duplex. You can
run a single-mode fiber link up to 20 kilometers (12.43 miles). However, note that
power budget constraints must also be considered when calculating the maximum
cable length for your specific environment.
