7. Cleaning & Maintenance
Fiber connectors can be easily contaminated by dust or dirt, which can result in decreased optical input power. If optical
receiver power and RF output levels of the receiver decline, you should clean fiber connectors. The cleaning method is
recommended below:
a) Remove power from the receiver.
b) Carefully unplug the fiber connector from the adapter.
c)
Using isopropyl alcohol and lint-free wipes carefully clean the faces of the optical connector. After cleaning,
allow 1 to 2 minutes until the connector’s surface is dry.
