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.

Figure 22 shows the ferrule in an SC connector.
