Fiber Optic Devices
An optional slide-in 1000BASE-SX, 1000BASE-LX, or
1000BASE-X transceiver may be used for backbone and long
distance connections, or for ISP (Internet) connections. A
1000BASE-SX, 1000BASE-LX, or 1000BASE-X transceiver may
also be for connecting to a high-speed server.
Each single-mode fiber optic port requires 9/125 micron
multimode fiber optic cabling with an SC connector at both ends.
Each multimode fiber optic port requires 50/125 or 62.5/125
micron multimode fiber optic cabling with an SC connector at
both ends.

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 port on the switch and
the other end to the SC port on the other device. Since SC
connectors are keyed, the cable can be attached in only one
orientation.
