TPIM-F3
The TPIM-F3 shown in Figure 2-7 is an ST connector that supports
Single Mode fiber Optic cabling.

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).
