Fiber-Optic Connectors
Always make sure that you insert the connector completely into the socket. This
action is especially important when you are making a connection between a
module and a long distance (1.24 miles [2 kilometers]) or a suspected highly
attenuated network. If the link LED does not light, try removing the network cable
plug and reinserting it firmly into the module socket. It is possible that enough dirt
or skin oils have accumulated on the plug faceplate (around the optical-fiber
openings) to generate significant attenuation, reducing the optical power levels
below threshold levels so that a link cannot be made.
Use extreme care when removing or installing connectors so that you do not

damage the connector housing or scratch the end-face surface of the fiber. Always
install protective covers on unused or disconnected components to prevent
contamination. Always clean fiber connectors before installing them.
