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.
Appendix B: Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner Fiber optic cartridge cleaners are available from many vendors and are typically called “cartridge cleaners,” as shown in Figure 24. Figure 24. Cartridge Cleaner Note Do not use compressed air or aerosol air to clean a fiber optic connector.
