Performing Absolute Power Measurements

Performing Absolute Power Measurements

Absolute power measurements are necessary when performing system or
component monitoring, quality control, system, or component acceptance
and troubleshooting.

To perform an absolute optical power measurement,
1.
Perform an offset nulling.

2. Using an appropriate test jumper and connector adapter, connect the

DUT to the detector port.

3. Adjust the power meter to the correct wavelength, +0.000 dB or

1.0000 W/W correction factor, and set the display unit to dBm or W.

4. The absolute optical power can now be monitored and recorded.

Note: Using a PM-1620, absolute power can be simultaneously measured for

each independent channel. Simply apply each step of the above procedure
to all used channels.
