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/m
2
).
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.
What do I need for proper
cleaning?
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:
