Cleaning the Fiber Optic Connectors
The connection quality depends on two factors: the type of connector and the proper cleaning and
connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors
clean at all times, and keep the dust covers installed when the connectors are not in use.
connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors
clean at all times, and keep the dust covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean
the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
Caution
Use extreme care when removing or installing connectors so that you do not damage the connector
housing or scratch the end-face surface of the fiber. Always install protective covers on unused or
disconnected components to prevent contamination. Always clean fiber connectors before installing
them.

To clean the optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for
MT-RJ connectors) and follow the product directions. If a CLETOP cassette cleaner is not available,

Step 2
Remove any residual dust from the faceplate with clean, dry, oil-free compressed air.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into

Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly
into the aperture. Repeat the process if any contamination is detected.

The connectors used inside the system have been cleaned by the manufacturer and connected to the
adapters in the proper manner. The operation of the system should be error free if the customer provides
clean connectors on the application side, follows the previous directions, and follows these guidelines:
