Module Connectors
SC Connector
The SC connector, shown in
, is used to connect fiber-optic module ports or transceivers with
the external SMF or MMF network.
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

Note
Make sure that the optical connectors are clean before making the connections. Contaminated connectors
can damage the fiber and cause data errors. For information on cleaning the optical connectors, see the

Figure B-13 SC Fiber-Optic Connector
Always insert the network connector completely into the socket. A secure connection is especially
important when you are establishing a connection between a module and a long distance (1.24 miles)
(2 km) network or a module and 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
dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating
significant attenuation and reducing the optical power levels below threshold levels so that a link cannot
be made.

Caution
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.

MT-RJ Connector
The MT-RJ connector is a small form-factor fiber-optic connector used to connect modules to a SMF or
MMF optical network. (See
MMF optical network. (See
.) The small size of the MT-RJ connector, as compared with the
SC connector, allows for a greater port density on the modules. The MT-RJ connector is a two-fiber
connector (transmit and receive) and has a form factor and clip lock retainer similar to the RJ-45 copper
connector.
