Appendix B: EPIM Specifications

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).
