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 average + 3 dB

= -30.5 dBm peak).
