A.2.3 EPIM-F3 (Single Mode Fiber Optic Port)
Internal Transceiver: Cabletron Systems FOT-F3™ Fiber Optic
Type:
Note: Transmitter power is inversely proportional to temperature rise.
Use the Output Power Coefficient to calculate increased or decreased
power output for your operating environment. For example, typical
power output at 25C equals -16.4 dBm. For a 4C 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 dBm = -17.0 dBm).
