Cleaning
When.necessary,.clean.the.case,.front.panel,.and.rubber.boot.with.a.damp.cloth..Do.not.use.
abrasives, harsh chemicals, or solvents.
Before Cleaning
Make.sure.the.power.is.off.to.the.instrument.
Make.sure.the.laser.source.is.off.when.cleaning.any.optical.connectors.
Make sure AC power is disconnected.
Cleaning Interfaces and Connectors
Interfaces.must.be.kept.clean..Isopropyl.alcohol.may.be.used.to.clean.the.optical.output..Always.
replace the protective dust caps when the unit is not being used, and keep the protective dust caps
clean. In addition, flanges must be cleaned periodically.
Notes:
The.diameter.of.optic.core.is.9.um,.and.the.diameter.of.dust.and.other.particulates.ranges.
from 1/100 to 1/1000 um. Dust and other particulates can cover part of the optical end and
therefore.degrade.the.performance.of.the.instrument.
In addition, power density may burn dust into optical fiber and induce further damage
(for example, 0 dBm optic power may produce about 16000000 W/m*m power density in
single mode fiber). If this happens, the measurement will be inaccurate and damage will be
irreversible.
Tools for Cleaning Interfaces and Connectors
Optical fiber cleaner (for cleaning optical connectors)
Optical fiber cleaning rod (for cleaning optical outputs)
Optical fiber cleaning tissue (for cleaning optical interfaces)
Isopropyl.alcohol
Paper.tissue
Cleaning brush
Cleaning swabs
Condensed air
Procedure for Cleaning Interfaces and Connectors
1.. Unscrew.the.adapter.from.the.bulkhead.
2. Carefully clean the bulkhead and the inside of the adapter.
3.. Screw.the.adapter.back.onto.the.bulkhead.
