Fiber Optic TPIM Specifications

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).
