FIBER OPTIC INTERFACE

Type:	FOT-F3:	ST fiber optic ports.
Parameter	Typical	Minimum	Maximum
Receive	-31.0 dBm	-33.5 dBm	-29.5 dBm
Sensitivity:
Max. Receive
Input Power:	-7.5 dBm	-9.72 dBm	-6.99 dBm
Transmitter Power
at 25° C
Into 8.3/125
μm fiber:	-15.0 dBm	-19.5 dBm	-12.0 dBm
Output Power	-0.15	-0.12	-0.18
Coefficient:	dBm/°C	dBm/°C	dBm/°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 (-0.15 dBm) by four and add the result to typical output power (4 x -0.15 dBm + -16.4 = -17.0).
