INSTALLATION REQUIREMENTS/SPECIFICATIONS

2.3.2EPIM-F1 and EPIM-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).
