Parameter Typical Minimum Maximum
Receive Sensitivity -31.0 dBm -36.0 dBm -30.0 dBm
Max. Receive Input
Power
-14.0 dBm
Transmitter Power at
25°C Into 8.3/125 µm
fiber:
-18.0 dBm -21.0 dBm -15.0 dBm
Output Power
Coefficient
-0.07 dB/°C
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 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 (-0.07 dB) by four and add the
result to the typical output power (4°C x -0.07 dB/°C) +
(-16.4dBm) = -16.7).
