4 Cleaning Information
Other Cleaning Hints
Selecting the correct cleaning method is an important element in
maintaining your equipment and saving you time and money. This
Appendix highlights the main cleaning methods, but cannot address every
individual circumstance.
This section contain some additional hints which we hope will help you
further. For further information, please contact your local Keysight
Technologies representative.
Making the connection
Before you make any connection you must ensure that all light-wave
cables and connectors are clean. If not, then use appropriate the cleaning
methods.
When you insert the ferrule of a patch-cord into a connector or an adapter,
ensure that the fiber end does not touch the outside of the mating
connector or adapter. Otherwise, the fiber end will rub up against
something which could scratch it and leave deposits.
Lens cleaning papers
Some special lens cleaning papers are not suitable for cleaning optical
devices like connectors, interfaces, lenses, mirrors and so on. To be
absolutely certain that a cleaning paper is applicable, please ask the
salesperson or the manufacturer.
Immersion oil and other index matching compounds
Do not use immersion oil or other index matching compounds with optical
sensors equipped with recessed lenses. They are liable to dirty the
detector and impair its performance. They may also alter the property of
depiction of your optical device, thus rendering your measurements
inaccurate.
