Note: The transmitter power levels and receive sensitivity levels listed

above are Peak Power Levels after optical overshoot. A Peak Power

Meter must be used to correctly compare the values given above to those

measured on any particular port. If Power Levels are being measured with

an Average Power Meter, then 3 dBm must be added to the measurement

to correctly compare those measured values to the values listed above

(i.e. -30.5 dBm peak=-33.5 dBm average).

Ethernet Port - EPIM-F3

Internal

Transceiver: Cabletron Systems FOT-F3™ Fiber Optic Transceiver

Type: ST ﬁber optic ports.

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).
