The transmitter power and receive sensitivity levels, below,
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 measured values to the values below (e.g., -29.5
dBm peak = -32.5 dBm average).
