REQUIREMENTS/SPECIFICATIONSPage 2-15TPIM-F3The TPIM-F3 shown in Figure 2-7 is an ST connector that supportsSingle Mode fiber Optic cabling.Figure 2-7. The TPIM-F3Note: Transmitter Power decreases as temperatures rise and increasesas temperatures fall. Use the Output Power Coefficient to calculateincreased or decreased power output for your operating environment.For example, the typical power output at 25°C is -16.4 dBm. For a 4°Ctemperature 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).TPIM-F3LNKRX TXReceiveSensitivitydBmLess Power More Power-40 -35 -30 -25 -20 -15 -10 -5 0MaximumReceiveInput PowerTransmitter Power*(At 25°C into8.3/125μm fiber)Minimum Sensitivity (-30.0)Typical Sensitivity (-31.0)Maximum Sensitivity (-36.0)Maximum Receive Input (-6.99)Typical Receive Input (-7.5)Minimum Receive Input (-9.72)Maximum Transmit Power (-12.0)Typical Transmit Power (-15.5)Minimum Transmit Power (-21.0)* Transmit Power Typical Power Minimum Power Maximum PowerCoefficient(See Note Below)-0.15dBm/ °C -0.12 dBm/ °C-0.18 dBm/ °C
