Transmitter Power decreases as temperatures rise and increases as
temperatures fall. Use the Output Power Coefficient to calculate increased or
decreased power output for your 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).
NOTE
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 correctly compare the
average power values measured to the values listed above (i.e., -33.5 dBm a 3 dB
= -30.5 dBm peak).
