The transmitter power levels given in Table A-3 are Peak Power Levels after optical overshoot. A Peak Power Meter is required to correctly compare the values given above to those measured on any particular port. When measuring power levels with an Average Power Meter, add 3 dBm to the average power measurement to correctly compare the average power values measured to the values listed in Table A-3 (i.e., -33.5 dBm average + 3 dB = -30.5 dBm peak).
