Copper and Fiber-Optic Connectors
Category 5e, Category 6, and Category 6a cables can store high levels of static electricity because of the

dielectric properties of the materials used in their construction. Always ground the cables (especially in
new cable runs) to a suitable and safe earth ground before connecting them to the module.
To comply with GR-1089 intrabuilding, lightning-immunity requirements, you must use foil-twisted pair

Fiber-Optic Connectors

This section describes the SC and LC fiber-optic connectors used by the optical transceivers.
SC Connectors
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into

beams or view directly with optical instruments. Statement 1051
The SC connector is used to connect fiber-optic module ports with the external network. (See

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.
