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:
• Dust and shutter caps
• Isopropyl alcohol
• Cotton swabs
• Soft tissues
• Pipe cleaner
• Compressed air
Dust and shutter caps
All of Agilent 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.
If you need further dust caps, please contact your nearest Agilent Technologies 
sales office. 
Isopropyl alcohol
This solvent is usually available from any local pharmaceutical supplier or 
chemist's shop.
If you use isopropyl alcohol to clean your optical device, do not immediately dry 
the surface with compressed air (except when you are cleaning very sensitive 
optical devices). This is because the dust and the dirt is solved and will leave 
behind filmy deposits after the alcohol is evaporated. You should therefore first 
remove the alcohol and the dust with a soft tissue, and then use compressed air to 
blow away any remaining filaments.
