Appendix B Cleaning Fiber Optic Connectors This appendix provides how to clean fiber optic connectors and consists of the following sections: “Overview” on page 80 “Cleaning Using a Cartridge-Type Cleaner” on page 81 “Cleaning Using a Swab” on page 83 79
AT-2874SX Gigabit Ethernet Fiber ExpressCard Installation and User’s Guide Overview 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 as shown in Figure 49. Light signals are transmitted through the core of the fiber. Ferrule Figure 49.
Appendix B: Cleaning Fiber Optic Connectors Cleaning Using a Cartridge-Type Cleaner Fiber optic cartridge cleaners are available from many vendors and are typically called “cartridge cleaners,” as shown in Figure 51. Figure 51. Cartridge Cleaner Note Do not use compressed air or aerosol air to clean a fiber optic connector. To clean a fiber optic connector using a cartridge cleaner, perform the following procedure: 1.
AT-2874SX Gigabit Ethernet Fiber ExpressCard Installation and User’s Guide Note Rub the ferrule tip on the cleaning surface in one direction only. 3. When you reach the end of the cleaning surface, pick up the ferrule tip, rotate and place it at the top and rub downwards at least 2 times. Caution Failing to pick up the ferrule tip when you reach the bottom of the cleaning surface can result in static electricity that can damage the fiber optic cable. 4. If desired, repeat steps 2 and 3. 5.
Appendix B: Cleaning Fiber Optic Connectors Cleaning Using a Swab Specially treated swabs (stick cleaners) are available for cleaning inside connector adapters or hard-to-reach ferrule tips. These swabs, often referred to as “lint free” or “alcohol free” swabs, are available from many vendors. See Figure 53. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes for use on SC and MU connectors respectively. Note NEVER use a household cotton swab and/or alcohol to clean a fiber optic connector.
AT-2874SX Gigabit Ethernet Fiber ExpressCard Installation and User’s Guide 3. If a fiber inspection scope is available, use the scope to inspect the connector to make sure that it is clean. 4. Reconnect the cable to the port or protect the ferrule tip with a dust cap.
