Figure B-8 LC Fiber Optic Connector
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.
Cleaning instructions for fiber-optic connectors is located in
Fiber-Optic Connectors" section on page
When you disconnect the fiber-optic cable from the module, grip the body of the
connector. Do not grip the connector jacket-sleeve. Gripping the sleeve can, over
time, compromise the integrity of the fiber-optic cable termination in the MT-RJ
connector.
Fiber-optic connectors are used to connect two fibers together. When these
connectors are used in a communications system, proper connection is critical.
Fiber-optic connectors differ from electrical connectors or microwave connectors.
In a fiber-optic system, light is transmitted through an extremely small fiber core.
Because fiber cores are often 62.5 microns or less in diameter in MMF and 8.3 to
10 microns in SMF, dust particles and any contamination on the face of the fiber
core can degrade the performance of the connector interface where the two cores
meet. The connector must be precisely aligned, and the connector interface must
be absolutely free of trapped contaminants.
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.
