The transmitter power levels and receive sensitivity levels listed in
Table B-1 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 add 3 dBm to the measurement to
correctly compare those measured values to the values listed above (e.g.,
-29.5 dBm peak = -32.5 dBm average).
