A.3.2 TPIM-F3 for Single Mode Fiber
The TPIM-F3 connector supports Single Mode Fiber Optic cabling.
Transmitter Power decreases as temperatures rise. Use the Output Power
Coefficient (-0.15 dBm) to calculate increased or decreased power output
for the 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).
