Error Rate
The transmitter power levels and receive sensitivity levels listed are Peak Power
Levels after optical overshoot. A Peak Power Meter must be used to correctly
NOTE
compare the values given above to those measured on any particular port. If
Power Levels are being measured 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).
