The above transmitter power levels and receive sensitivity
levels represent Peak Power Levels after optical overshoot.
You must use a Peak Power Meter to correctly compare the
above values to those you measure on any particular port. If
you measure Power Levels with an Average Power Meter,
you must subtract 3 dBm from the measurement to correctly
compare those measured values to the values listed above
(e.g., -29.5 dBm peak = -32.5 dBm average).
