2.4.2 Cleaning Fiber Optic Devices
This section covers the cleaning requirements and procedures for the fiber optic cable
connectors and the optical ports on the DX40. Clean the connectors after each use and
the optical ports when contamination is suspected or there is a performance degradation
which may be attributable to contamination. All fiber optic connectors and optical ports
should be capped with dust caps when not in use.
The cleaning materials used should be rated for fiber optic devices. Specifically cloth,
wipes and swabs should be lint-free, non-abrasive and free of additives. Cleaning fluids
should be restricted to optical-grade isopropyl alcohol. Canned (compressed) air should
be used to blow out dust and particulate matter and to dry residual isopropyl alcohol after
cleaning.
2.4.2.1 Cleaning Connectors
These instructions are recommended each time a fiber optic connector is used. Clean the
fiber optic connectors as follows:
1.Blow out any dust or particulate matter from the connector end, using canned
air.
2.Wipe out the connector end surfaces with a cloth or pad saturated in isopropyl
alcohol.
3.Blow dry the connector surfaces, using canned air, by directing the air flow
across the tip but not directly down onto the tip.
4.Using care not to touch the fiber tip, install a dust cap or connect to an optical
port.
2.4.2.2 Cleaning Optical Ports
These instructions are recommended only when there is evidence of contamination or
when reduced performance has been detected. Clean the optical ports as follows:
1.If required, remove the fiber optic connector from the optical port and clean the
connector as described in “Cleaning Connectors,” above.
2.Insert the extension tube, supplied with the canned air, into the canned air
nozzle and blow out the optical port. Use care not to touch the bottom of the
optical port.
3.Reconnect the fiber optic connector removed in step 1.
