Testing Fibers in Advanced Mode
MAX-700 57
To acquire traces:
1. Clean the connectors properly (see Cleaning and Connecting Optical
Fibers on page 42).
2. Connect a fiber to the OTDR port.
If your unit is equipped with two OTDR ports, ensure that you connect
the fiber to the appropriate port (singlemode, singlemode live, or
multimode), depending on the wavelength you intend to use.
3. If you want the application to provide automatic acquisition values, set
the autorange acquisition time (see Setting the Autorange Acquisition
Time on page 60).
4. If you want to set your own IOR (group index), RBS coefficient or helix
factor, see Setting the IOR, RBS Coefficient, and Helix Factor on
page 61.
5. Go to the OTDR tab.
6. If you want to test in high resolution, simply select the feature (see
Enabling the High-Resolution Feature on page 66).
C
AUTION
Never connect a live fiber to the OTDR port without a proper setup.
Any incoming optical power ranging from –65 dBm to –40 dBm will
affect the OTDR acquisition. The way the acquisition will be
affected depends on the selected pulse width.
Any incoming signal greater than 10 dBm could damage your
MAX-700 permanently. For live-fiber testing, refer to the SM Live
port specifications for the characteristics of the built-in filter.
