Chapter 2: INSTALLATION REQUIREMENTS/SPECIFICATIONS
The transmitter power levels and receive sensitivity levels given in
Figure 2-3 are Peak Power Levels after optical overshoot. You must
NOTE
use a Peak Power Meter to correctly compare the values given
above to those measured on any particular port. If you measure
power levels with an Average Power Meter, then 3 dBm must be
added to the measurement to correctly compare those measured
values to the values listed (i.e., -30.5 dBm peak = -33.5 dBm
average).
