Measurement Results
The meter measures the length of the fiber. The length can be
the distance to an APC or UPC connector at the end of the fiber
or the distance to a break. If there is a large reflective event
before the end of the fiber (larger than the dB LIMIT setting) the
meter shows the distance to that event.
The meter can show these results in the given situations:
The meter shows
•
The connection to the meter is bad.
•
The connector on the meter or the fiber is dirty. See page 11
for instructions on how to clean the connectors.
•
The meter is connected to a PC connector. PC connectors
cause large reflections that the meter shows as the end of
the fiber.
The meter shows
The fiber is longer than the meter can measure.
The meter shows
APC connectors make very small reflections. On some short
fibers, this small reflection is hidden in the reflection from the
bulkhead connector on the meter. In these situations, the meter
shows a range (for example, < 9 m), rather than an exact length.
The length measurement is incorrect.
•
The I.O.R. (index of refraction) is incorrect. See page 8.
•
The cable has PC connectors. PC connectors cause large
reflections that the meter shows as the end of the fiber.
