The transmitter power levels given above are Peak Power Levels after
optical overshoot. Use a Peak Power Meter to compare the values given
above to those measured on any particular port. To measure power levels
with an Average Power Meter, add 3 dBm to the average power
measurement to compare the average power values measured to the
values listed above (i.e., -33.5 dBm average + 3 dBm = -30.5 dBm peak).
