What Do I Need For Proper Cleaning - Keysight N7744A User Manual

What do I need for proper cleaning?

Keysight N774x Series
Furthermore, the power density may burn dust into the fiber and cause
additional damage (for example, 0 dBm optical power in a single mode
fiber causes a power density of approximately 16 million W/m2). If this
happens, measurements become inaccurate and non-repeatable.
Cleaning is, therefore, an essential yet difficult task. Unfortunately,
when comparing most published cleaning recommendations, you will
discover that they contain several inconsistencies. In this section, we
want to suggest ways to help you clean your various optical devices, and
thus significantly improve the accuracy and repeatability of your
lightwave measurements.
Some Standard Cleaning Equipment is necessary for cleaning your
instrument. For certain cleaning procedures, you may also require
certain Additional Cleaning Equipment.
Standard Cleaning Equipment
Before you can start your cleaning procedure you need the following
standard equipment:
•
Dust and shutter caps
•
Isopropyl alcohol
•
Cotton swabs
•
Soft tissues
•
Pipe cleaner
•
Compressed air
Dust and shutter caps
All of Keysight Technologies' lightwave instruments are delivered
with either laser shutter caps or dust caps on the lightwave adapter.
Any cables come with covers to protect the cable ends from damage
or contamination.
We suggest these protected coverings should be kept on the equipment
at all times, except when your optical device is in use. Be careful when
replacing dust caps after use. Do not press the bottom of the cap onto
the fiber too hard, as any dust in the cap can scratch or pollute your
fiber surface.
