Fiber Optic Devices
An optional slide-in 100BASE-FX module may be used for backbone and long
distance connections. A 1000BASE-X module may also be used for a backbone
connection between switches, or for connecting to a high-speed server.
Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber
optic cabling with an SC connector at both ends. If you need to connect to a device
with 62.5/125 micron cable that has ST-type connectors, Accton provides an
optional SC-ST Converter (Part Number: ST5002).
Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with
an SC connector at both ends.
Caution: 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 cover. When not connected to a fiber
cable, the rubber cover 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 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.

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.
Note:
If you use the optional SC-ST Converter, be sure to connect the converter's Tx
(Rx) port to the Rx (Tx) port on the other device.
