Only use pipe cleaners on connector interfaces or on feed through
adapters. Do not use them on optical head adapters, as the center of a pipe
cleaner is hard metal and can damage the bottom of the adapter.
Your pipe cleaner should be new when you use it. If it has collected any
dust or dirt, this can scratch or contaminate your device.
The tip and center of the pipe cleaner are made of metal. Avoid
accidentally pressing these metal parts against the inside of the device, as
this can cause scratches.
Compressed air can be purchased from any laboratory supplier.
It is essential that your compressed air is free of dust, water and oil. Only
use clean, dry air. If not, this can lead to filmy deposits or scratches on the
surface of your connector. This will reduce the performance of your
transmission system.
When spraying compressed air, hold the can upright. If the can is held at a
slant, propellant could escape and dirty your optical device. First spray into
the air, as the initial stream of compressed air could contain some
condensation or propellant. Such condensation leaves behind a filmy
deposit.
Please be friendly to your environment and use a CFC-free aerosol.
Additional Cleaning Equipment
Some Cleaning Procedures need the following equipment, which is not
required to clean each instrument:
• Microscope with a magnification range about 50X up to 300X
• Ultrasonic bath
• Warm water and liquid soap
• Premoistened cleaning wipes
• Polymer film
• Infrared Sensor Card
A microscope can be found in most photography stores, or can be obtained
through or specialist mail order companies. Special fiber-scopes are
available from suppliers of splicing equipment.
Ideally, the light source on your microscope should be very flexible. This
will allow you to examine your device closely and from different angles.
A microscope helps you to estimate the type and degree of dirt on your
device. You can use a microscope to choose an appropriate cleaning
method, and then to examine the results. You can also use your
microscope to judge whether your optical device (such as a connector) is
severely scratched and is, therefore, causing inaccurate measurements.
