4.2 How to clean the optical output interface of OTDR?
The optical output interface of OTDR is a
replaceable interface, which must be kept
clean. When the instrument is unable to test
the normal curve or the test results are
inaccurate, the first consideration is to clean
the optical interface of the instrument.
Specific cleaning methods: unscrew the
output interface, wipe the end face of
ceramic core with clean cotton sheets or
special paper towels and cotton swabs
wetted by alcohol, and then screw the
output interface after the end alcohol evaporates.
Tip 1: Before cleaning, make sure both OTDR and VFL function are stopped!
Tip 2: In the normal use of the instrument, please cover the dust cap after it is finished, and keep the
dust cap clean at the same time!
