Cover an optical module with an optical connector
Lay the optical fibers on the Optical-fiber Distribution Frame (ODF) or coil them up in a
fiber management tray. Make sure that the optical fibers are not squeezed.
If a receptacle or an optical connector has not been used for a long time and not covered
with a dust cap, you should clean it before using it. A cotton swab is used to clean a
receptacle, and a cleaning tissue is used to clean an optical connector.
NOTE
During the cleaning process, insert the cotton swab and turn it slowly in the receptacle. Do not use too
much strength, because the receptacle may be damaged.
