Connecting Fiber Cable
When connecting fiber cable to a 100BaseFX port on the product, be sure the correct
type – ST, SC, or WDM (available via special order) - connector is used. Follow the
steps below to properly connect fiber cable:
1.
Remove and keep the ST/SC/WDM 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 optic cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the port.
Connect one end of the cable to the ST/SC/WDM port on the Device Server /
3.
Managed Media Converter and the other end to the ST/SC/WDM port on the
other device.
NOTE: When inserting the cable, be sure the tab on the plug clicks into position to
ensure that it is properly seated.
Check the corresponding port LED on the Device Server / Managed Media
4.
Converter to be sure that the connection is valid. (Refer to the LED chart in next
section)
Warning:
Because invisible laser radiation may be emitted from the
aperture of the fiber port when no cable is connected, avoid exposure
to laser radiation and do not stare into the open apertures.
