Inspecting Fiber-optic Connector and Receptacle End Faces
Inspecting Fiber-optic Connector and
Receptacle End Faces
This procedure applies to all fiber-optic connector types and assumes
that all of these conditions are met:
l You turned off any laser sources before you inspect the fiber
connectors, optical components, or fiber-optic bulkhead connectors
(FOBCs);
l You disconnected the cable at both ends;
l You correctly installed the traffic modules and pluggable transceivers;
and
l You reviewed the Laser and LED Safety Guidelines and Warnings
and all safety guidelines.
1. Verify that you are properly grounded with an anti-static wrist strap or heel strap
connected to the grounded ESDjack.
LASERRADIATIONWARNING
Laser Radiation is present when the equipment is open and the interlocks
are defeated. Avoid exposure to the beam.
2. Switch any forced laser back to auto or off.
3. Disconnect the fiber-optic cables. If no fiber-optic cables are connected, remove the
dust cover or dust plug from the module.
4. Use an optical power meter to verify the output power of the common output ports.
Handle the connectors carefully to avoid leaving fingerprints or
otherwise contaminating the ferrule end face.
5. Use canned, oil-free compressed air to blow away any accumulated dust or loose
debris from the ferrules.
6. Use an appropriate hand-held fiber scope or video scope to inspect the port
connectors or receptacles and ensure that they are clean. See the illustration that
follows for comparison examples of clean and contaminated fiber end faces.
Use a hand-held fiber scope or video scope that is compatible with the
connector type you are cleaning.
