The transmitter power levels and receive sensitivity levels listed are
Peak Power Levels after optical overshoot. A Peak Power Meter
NOTE
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 (i.e. -30.5 dBm peak=-33.5 dBm average).
EPIM-F3
The EPIM-F3 supports Single Mode Fiber Optic cabling. It has an internal
Cabletron Systems FOT-F™ Fiber Optic Transceiver and is equipped with ST
Connectors. Figure B-3 shows the EPIM-F3. Specifications for the EPIM-F3 are
listed below.
Transmitter Power decreases as temperatures rise and increases as
temperatures fall. Use the Output Power Coefficient to calculate
NOTE
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).
