11 Starting the OTDR Application
You can start the classic OTDR application without leaving the iOLM
application. You can use this option to do real-time acquisitions with the
OTDR application and quickly switch back to the iOLM application to do
troubleshooting in a more user-friendly environment.
Note: EXFO recommends to run only one instance of the OTDR application per
module at a time, either the one you start from ToolBox, or the one you
start from the iOLM application.
Note: This option is available only when the OTDR or RT software option is
activated.
To use the OTDR application:
1. From the Main Menu, tap Launch OTDR.
Note: You cannot do any operations related to hardware when the classic OTDR
application is started. You will be notified that you need to close the OTDR
application to allow interaction with the hardware.
