Measures to Prevent Receptacle Contamination
1. Cleaning tissues must be prepared on site. You need to clean the optical connector before
inserting it in the receptacle. This protects the receptacle against contamination on the
surface of the optical connector.
Figure 13-96 Cleaning optical fibers with special cleaning tissues
NOTE
Place at least three cleaning tissues on the work bench. As shown in Figure 13-96, wipe the end of
an optical connector from left to right or from right to left on a cleaning tissue, and then move the
connector end to the unused part of the cleaning tissue to continue.
2. Cover an unused optical module with a protective cap to prevent dust, as shown in
Figure 13-97.
Figure 13-97 Installing a protective cap
If no protective cap is available, use fibers to protect the optical module, as shown in
Figure 13-98.
