Appendix B Port, Cable, and Connector Specifications

Copper and Fiber-Optic Connectors

Caution 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.

Caution To comply with GR-1089 intrabuilding, lightning-immunity requirements, you must use foil-twisted pair (FTP) cable that is properly grounded at both ends.

Fiber-Optic Connectors

This section describes the SC and LC fiber-optic connectors used by the optical transceivers.

SC Connectors

Warning 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

Figure B-3.)

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.
