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.

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).
