Monitoring Fiber in Real Time Mode
You can monitor fiber at one wavelength at a time. You can also switch
from Real time mode to Manual mode at any time.
If you intend to test at multimode wavelengths, carefully read
Conditions for Multimode Measurements
To monitor fiber in Real time mode:
1.
Clean the connectors properly (see
Cleaning and Connecting Optical
2.
Connect a launch fiber between the device under test and the OTDR
port. If necessary, set the

and display
the pane (F1/F2 key).
If your unit is equipped with two OTDR ports, ensure that you connect
the fiber to the appropriate port (OTDR SM, OTDR MM, or
OTDR SM Live for filtered wavelength).

AUTION
Never connect a live fiber to the OTDR SM or OTDR MM port. Any
incoming signal greater than –40 dBm will affect the OTDR
acquisition. Any incoming signal greater than –20 dBm could
damage your OTDR permanently.
