Cleaning and Inspecting Fibers and Ports
CAUTION
Only Service Personnel are allowed to perform this procedure.
Raman amplifiers are high-powered devices. Always set the Network Port on a
Raman amplifier to disabled before removing an optical cable. Failure to disable the
network port can result optical connector damage.
Step 1 Review the contents of the
Safety Guide
. Also observe all caution statements
in this section.
CAUTION
Laser Radiation is present when the equipment is open and the
interlocks are defeated. Avoid exposure to the beam.
Step 2 Switch any forced laser back to auto (or off).
Step 3 Disconnect the fiber-optic cables. If no fiber-optic cables are connected,
remove the protective cover from the plugs.
Step 4 Use an optical power meter to check the output power of the common output
ports.
Note
Handle the connectors carefully, to avoid leaving fingerprints or
otherwise contaminating the ferrule endface.
Step 5 Blow off any accumulated dust or loose debris from the ferrules with canned,
oil-free compressed air.
Note
Do not use commercial, compressed air due to the risk of oil
contamination of the fiber-optic connectors and receptacles. Always use
canned, oil-free compressed air.
Step 6 Use a video scope (as shown in Figure 1 on p.î36) to inspect the ports and to
ensure that the port connectors are clean. (See Figure 2 on p.î36 for
comparison examples of clean and contaminated fiber endfaces).
CAUTION
Never look directly into an optical fiber connector or into an un-terminated
receptacle during service operations by using optical instruments, such
as a magnifier or video scope, unless you are absolutely certain that no
laser radiation is being emitted from the receptacle or the fiber.
