NOTES
The transmitter power levels given above are Peak Power
Levels after optical overshoot. You must use a Peak Power
Meter to correctly compare the values given above to those
measured on any particular port.
Levels after optical overshoot. You must use a Peak Power
Meter to correctly compare the values given above to those
measured on any particular port.
If you are measuring power levels with an Average Power
Meter, add 3 dBm to the average power measurement to
compare the measured average power values to the values
listed above (i.e., -33.5 dBm average + 3 dB = -30.5 dBm peak).
