Direct Transmitter Output Power Measurement
To measure the output power from a transmitter, use the following steps:
Connect the WaveTester to the transmitter port on the active equipment
under test, as shown at right.
Press
to power on the WaveTester optical power meter, if necessary.
Determine the output wavelength of the active equipment, then press
until the wavelength on the WaveTester matches.
Power on the transmitter port according to manufacturer instructions, if
necessary.
Monitor the reading on the screen for a few seconds. This reading may fluctuate if the output signal is made up of digital
zeroes (0) and ones (1). In this case, estimate the average power level. To calculate maximum output power, add 3 dB
to the average power level.
Some transmitters have a diagnostic mode where the output is continuously at its maximum power. This
eliminates the need to compensate 3dB for digital data transmission. Consult the active equipment
manufacturer’s operations guide for more information.
Receive Power Measurement
The WaveTester may also be used to measure optical power levels from a
transmitter through an installed link to ensure that the Receive power at the far
end is within manufacturer specifications.
Follow the same steps as above, except the WaveTester must be connected to
the active equipment under test through the installed link as shown at right.
