Calibrating Your System for ORL Testing
Calibrating Your System for ORL Testing
This operation measures ORL in the system before testing DUTs. The
results obtained will be used to calculate the ORL specific to the DUTs.
To perform an ORL calibration:
1. Connect an ORL reference test jumper to output port 1 of the switch.
2. Perform an ORL calibration scan.
3. Mandrel the ORL reference test jumper.
4. Perform an ORL zero measurement.
5. Repeat steps 1 to 4 for all of the switch ports.
Optimizing Power
This operation allows to adjust the power from the IQS-5150 to its optimum
level.
To optimize power:
1. Connect the patchcords to the appropriate modules (source,
polarization state adjuster, wavelength reference module and switch) .
2. Connect output port 1 of the switch to channel 1 of the power meter.
3. Perform the power optimization.
