Appendix B
Cleaning Fiber Optic Connectors
This section describes how to clean fiber optic connections. The fiber optic
connector consists of a fiber optic plug and its adapter. The end of the fiber optic
cable is held in the core of the ferrule in the plug. Light signals are transmitted
through the core of the fiber. Even minor smudges, or dirt, on the end face of the
fiber (completely invisible to the naked eye) can disrupt light transmission and
lead to failure of the component or of the entire system. Therefore, it is of utmost
importance to clean all fiber optic connectors before use.
