a cleaning kit to clean the ferrule, the protectivewhite tube around the fiber, and
the end-face surface of the fiber.
Asa general rule, whenever there is a significant, unexplained loss of light, clean
the connectors.
Caution Useextreme care when removing or installing connectors so you do
notdamage the connector housing or scratch the end-face surface of
thefiber. Always install protectivecovers on unused or disconnected
components to prevent contamination. Always clean fiber
connectors before installing them.
Use a swab saturated with isopropyl alcohol to clean the end-surfaces. Use dry,
oil-free compressed air after applying the isopropyl alcohol.
