Cleaning and Inspecting Fibers and Ports
Step 1 Review the contents of the Safety Guide. Also observe all caution statements
in this section.
Step 2 Check the operating status of the equipment and the current hazard level. If
any module in the system is operating in “Forced On” mode, this could have an
effect on the hazard level of the NE.
CAUTION
Laser Radiation is present when the equipment is open and the
interlocks are defeated. Avoid exposure to the beam.
Step 3 Clean fiber-optic connectors, as described in “Cleaning Fiber-Optic Connector
Plugs” on p.34, before plugging them into the receptacles.
Step 4 If the optical receptacle is contaminated, carefully insert the extension tube of
the compressed air can into the optical receptacle and blow dry, oil-free air into
the connector. Avoid touching the adaptor receptacle.
Step 5 Carefully reconnect the optical connector plug, and check for proper function. If
the performance is not sufficient, repeat the cleaning procedure.
Note
If problems persist after repeated cleaning, replace the optical module.
Send the removed module to ADVA Optical Networking Technical
Services.
Step 6 If no optical fiber cable is reconnected, cover the connector receptacle with
plugs to avoid contamination.
Cleaning and Inspecting Fiber Jumpers
Use these procedures to inspect and clean fiber jumpers (fiber patch cords).
Dry Cleaning Technique Using Cartridge and Pocket-
Style Cleaners
This section describes dry cleaning techniques using cartridge and pocket-style cleaners.
Step 1 Make sure that the lasers are turned off before beginning the inspection.
CAUTION
Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical
instruments.
Step 2 Remove the fiber caps from one or more jumpers and store them in a small,
resealable container.
