      Hello Lama,
      Typically, the launch power is referred to the power at the input of the fiber or the channel (FSO, etc…). You may place a power meter to the average power there.
      The power value is important for the DSP to enable the compensation of nonlinearity.
      Regards,
      Ahmad
