3.2 OTDR Function
The OTDR (Optical Time Domain Reflectometer) function is used to characterize optical fibers, measure fiber length, and locate faults. To use the OTDR function, select "OTDR" from the main menu. Ensure the fiber is properly connected to the OTDR port. The device will display a trace of the fiber, showing events like splices, connectors, and breaks.
