Cleaning the optical interfaces

Follow the instructions below when cleaning the optical interfaces [17], [18], [44], [47], [103] and
[113] (see Fig. M-2):
1. Always observe the laser safety precautions!
2. Remove the test adapter and protective cap (a).
The internal plug pin is now easily accessed.
3. If the plug pin is very dirty, dab it lightly with a piece of adhesive tape (e.g. Scotch "Magic
tape"), then remove the tape (b).
For on-site cleaning, we recommend the use of "Cleaning tape for optical connectors", BN
2229/90.07.
4. If the plug pin is not very dirty, dampen a lint-free paper tissue with isopropanol and wipe off
the end surface of the plug pin (c).
5. Dry off the end surface of the plug pin using a dry paper tissue (d).
6. Blow out the test adapter and protective cap using clean, compressed air.
7. Replace the test adapter and protective cap on the connector.

A suitable microscope is required for inspecting the plug end surfaces. This should have a
magnification of about 200 x.
