NOTE: Transmitter Power decreases as temperatures rise and increases
as temperatures fall. Use the Output Power Coefficient to calculate
increased or decreased power output for an 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 provided above are Peak Power
Levels after optical overshoot. Use a Peak Power Meter to correctly
compare the values given to those measured on any particular port.
When measuring power levels with an Average Power Meter, add 3 dBm
Fall Time 2.5 nsec 2.2 nsec 5.0 nsec
