2.3.2 EPIM-F1/F2
The EPIM-F1 and EPIM-F2 shown in Figure 2-4 support Multimode
Fiber Optic cabling. Each EPIM has an internal Cabletron Systems
FOT-F™ Fiber Optic Transceiver. The EPIM-F1 is equipped with
SMA Connectors and the EPIM-F2 is equipped with ST Connectors.
Specifications for the EPIMs are listed below.

Note: The transmitter power levels and receive sensitivity levels
listed 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 (i.e. -30.5 dBm peak=-33.5 dBm average).
