Transmitter Power decreases as temperatures rise and increases as temperatures fall. Use the Output Power Coefficient to calculate increased or decreased power output for the operating environment. For example, the typical power output at 25°C is -16.4 dBm. For a 4°C temperature increase, multiply the typical coefficient (-0.15 dBm) by four and add the result to typical output power (4 x -0.15 dBm + -16.4 = -17.0).

The transmitter power levels given above are Peak Power Levels after optical overshoot. Use a Peak Power Meter to compare the values given above to those measured on any particular port. If you are using an Average Power Meter, add 3 dBm to the measurement to compare the average power values to the values listed above

(i.e., -33.5 dBm average + 3 dBm = -30.5 dBm peak).
