OPERATION
DESCRIPTION
With a Clear-Com FIM-202D System, you can connect Clear-Com
intercom panels or interfaces to the central matrix using fiber-optic
cables at distances of up to 12 miles (20 km).
The system consists of one FIM-202D at the matrix-frame end and
another FIM-202D unit at the matrix-panel end. Connecting the pair of
interfaces with fiber rather than with the standard 4-wire twisted pair
copper, gives you advantages such as increased security from
electromagnetic and RF interference, flexibility in equipment
placement, ease of maintenance, and often, reduced cost.

CONNECTING INTERCOM PANELS TO THE CEN-
TRAL MATRIX
The Clear-Com FIM-202D system transmits audio and data signals
from 1 or 2 intercom panels or interfaces using easily available
standard Ethernet cable to the matrix frame through the process
illustrated in Figure 1-2. The illustration shows both directions of the
signal flow as the system transmits in full-duplex mode.
