Testing Fibers in Fault Finder Mode
OTDR 85
Enabling or Disabling the First Connector Check for Fault Finder
Enabling or Disabling the First Connector
Check for Fault Finder
The first connector check feature is used to verify that the fibers are
properly connected to the OTDR. It verifies the injection level and displays
a message when a unusually high loss occurs at the first connection, which
could indicate that no fiber is connected to the OTDR port. By default, this
feature is not enabled.
Note: The first connector check is only performed when you test at singlemode
wavelengths.
Note: The first connector check parameter used in Fault Finder mode is
independent from the one used in the other OTDR modes (Auto, Advanced
and Template).
