Select ‘LOCATE’ to measure the distance to the end of the
fiber. The display will indicate that the OFL 100 is searching for
the fiber end.
The measurement is first done by coarse approximation
(PASS 1),
then more accurately by fine measurement (PASS 2).
After several seconds, the display will read;
XXXXm is the distance of the fiber end measured in meters
(m) or feet (ft). The OFL 100 will indicate whether or not the
end termination is reflective. The letter “R” indicates that the
end is reflective, a ‘N’ indicates the end is non-reflective.
NOTE: After pressing LOCATE, the display may read;
This means the OFL 100 was unable to locate the fiber end,
however, the unit did identify fiber as far as XXXX meters. Note:
When an over-range record is saved and later transferred to
PCPLOT3 software an additional 20% of the tested fiber will
be displayed on the trace view screen.
This over-range feature is useful when measuring a fiber that
is longer than the maximum range of the OFL 100. If the unit
over-ranges, but can measure beyond halfway, then the entire
fiber length can be analyzed by measuring from both ends.
The OFL 100DM range is approximately 3 km in multimode
fiber (62.5/125 micron). The OFL 100DS range is approximately
5 km in singlemode fiber (9/125 micron).
