phenomenon at the front of
test curve.
Fiber coupling is not good.
Clean the instrument with clean cotton chips
and the measured optical fiber end face.
The reflection peak at the
beginning decreases slowly
and the tail appears.
The output surface of fiber is polluted.
Replacement of output connector.
The output connector is damaged.
Replace connectors.
Optical output connectors do not match. Replace matched connectors.
Reflection peak at the end of
optical fibers cannot be
measured
The range setting is too small.
Increase the test range value.
Pulse width setting is too small.
Increase the test pulse width parameters.
Misreporting in curve analysis
The quality of test curve is poor/the
setting of event threshold is small.
Increase the test pulse width parameter/increase
the event threshold.
The measurement of optical
fiber length is inaccurate
The parameter setting is incorrect.
Reset the appropriate parameters.
The refractive index setting of optical
fibers is inaccurate.
Reset the refractive index of the optical fiber.
Incorrect
setting
of
correction
coefficient for optical cable.
Reset the cable correction factor.
The average loss of optical
fibers measured is inaccurate.
The front end of the test curve is too
long.
Clean optical output face.
