Make sure that the optical connectors are clean before making the connections. Contaminated connectors

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.
Use extreme care when removing or installing connectors so that you do not damage the connector
Caution
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
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.
