Note: The transmitter power levels given above are Peak Power Levels
after optical overshoot. You must use a Peak Power Meter to correctly
compare the values given above to those measured on any particular
port. If you are 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 above (i.e., -33.5
dBm average + 3 dB = -30.5 dBm peak).
