Appendix B
Cleaning Fiber Optic Connectors
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.
