Various Useful Functions
● Waveform Comparison Function
Measured and saved data can be compared on the same
screen. In addition, differences can be displayed as
a waveform for simple observation of distance and level dif-
ferences. This is useful for checking aging changes
or comparing several fibers.
● Communication Light Check Function
When measuring a fiber in service, there is a possibility of mis-
measurement by an OTDR. To guard against the risk of mis-
measurement, this check function checks for the presence of
light other than the OTDR optical measurement pulse.
● Optical Channel Selector Control Function
In addition to using the built-in optical channel selector, external
MN9662A/9664A Optical Channel Selector can be controlled
via the RS-232C interface from an OTDR. By using these
selectors, an optical fibercable consisting of up to 32 cores can
be measured automatically.
● Warning Level Setup Function
In automatic measurement mode, an event warning value can
also be set in addition to a detection threshold value. For exam-
ple, the threshold value can be set to the acceptance level, and
warning value to a pass/rejection decision level. In this case, all
events will be detected, and those exceeding the warning value
are displayed in another color, therefore, enabling the operator
to easily identify possible “borderline” events.
