Type Rj-45 100Base-T Copper Cables; Removing And Installing Rj-45 100Base-T Copper Cable - Cisco XR 12000 Series Installation Manual

The connection quality depends on two factors: the type of connector and the proper cleaning and
connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors
clean at all times, and keep the dust plugs or covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean
the ferrule, the protective tube or cone that surrounds the fiber core, and the end-face surface of the fiber
core.
As a general rule, any time you detect a significant, unexplained loss of light, clean the connectors. To
clean the optical connectors, use a CLETOP fiber optic cleaning cassette (Type A for SC connectors)
and follow the manufacturer's usage instructions.
If a CLETOP cleaning cassette is not available, follow these steps:
Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol and gently wipe the end-face of the
Step 1
fiber core. Wait 5 seconds for the surfaces to dry and wipe the surfaces a second time.
Use clean, dry, oil-free compressed air to remove any residual dust from the connector.
Step 2
Warning Invisible laser radiation can be emitted from the aperture of the port when no cable is connected.
Avoid exposure to laser radiation and do not stare into open apertures.
Step 3 Use a magnifying glass or inspection microscope to inspect the ferrule at angle. Do not look directly into
the aperture. If you detect any contamination, repeat
