Cleaning Fiber Optic Connectors
To ensure absolute measurement accuracy and repeatability, fiber
optic connectors must always be cleaned before conducting a fiber
optic measurement. Dust and oil contamination on the connector end-
faces, as shown at right, can result in abnormally high insertion loss
readings and other anomalies.
Tempo recommends the use of the All-In-One cleaning tool for fiber
optic connectors in accordance with the enclosed instructions. If an
All-In-One cleaning tool is not available, the connectors should be
cleaned as follows:
1. Moisten a clean, lint-free cloth, such as Texwipe TX404, with
reagentgrade isopropyl alcohol.
2. Wipe once across the connector endface with the damp part of
the cloth using moderate pressure. Make sure the alcohol has
completely evaporated before commencing.
3. If possible, visually inspect the connector endface using a mag-
nifier or microscope, such as a Leica 200x FiberVue micro
scope, Tempo Part No. FVK-200/U25. If the end face still
appears dirty, clean it again.
WARNING: Never clean or visually inspect
a fiber optic connector under power.
Viewing the end of an optical fiber under
power can cause permanent eye damage or
blindness.
