fiber adapter in order to protect the surface from dirt.
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 lightwave
cables and connectors are clean. If not, then use appropriate the
cleaning methods.
When you insert the ferrule of a patchcord 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
Note that 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.
Updated versions of the firmware for your instrument may be released
from time to time. These will then be available from the Keysight web
page (www.keysight.com/find/octfirmware) and will include the
update application and instructions.
