Figure A-2. EPIM-F1 and EPIM-F2
Note : The transmitter power levels and receive sensitivity levels listed are
Peak Power Levels after optical overshoot. Use a Peak Power Meter
compare the values given above to those measured on any particular port.
If Power Levels are being measured with an Average Power Meter, add 3
dBm to the measurement to compare the measured values to the values
listed (i.e., -33.5 dBm average + 3 dBm =-30.5 dBm peak).
