the measured value is not within the
range,
choose an appropriate attenuator.

4
Replace the 0-dB attenuator by the chosen one.

5
Measure the received optical power again. To be able to do that a coupler and an extra
fiber jumper could be required.
Result:
The measured value must lie within the valid range.
