Enabling or Disabling the First Connector
Check
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 an 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.
When you use a switch in conjunction with your OTDR, the first connector
check will verify all selected channels before starting the acquisition
sequence. For more information on selecting channels, see Setting Optical
Switch Parameters on page 88.
To enable or disable the first connector check:
1. From the main window, press Setup then press the Acquisition tab.
2. To enable the first connector check, select the First Connector Check
box.

To disable it, clear the box.
