Connecting Fiber Cable
When connecting fiber cable to a 1000BASE-FX port on
the Converter, be sure the correct type – SC or WDM connector is used. Follow the steps below to properly
connect fiber cabling:
1. Remove and keep the fiber port's rubber cover. When
not connected to a fiber cable, the rubber cover
should be replaced to protect the fiber 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/WDM port on
the Converter and the other end to the SC/WDM port
on the other device.
4. Check the corresponding port LED on the Converter
to ensure that the connection is valid. (Refer to the
LED chart in next section)
Note: When inserting the cable, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
