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 on the supervisor engine or
route switch processor 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
Caution
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.

beams or view directly with optical instruments. Statement 1051
The MT-RJ style connector is used on fiber-optic modules to increase port density. (See
Figure B-6
When you are connecting MT-RJ cables to a module, make sure you firmly press the connector plug into
the socket. The upper edge of the plug must snap into the upper front edge of the socket. You may or
may not hear an audible click. Gently pull on the plug to confirm whether or not the plug is locked into
the socket. To disconnect the plug from the socket, press down on the raised portion on top of the plug
(releasing the latch). You should hear an audible click indicating that the latch has released. Carefully
pull the plug out of the socket.
