FIM-108 FIBER INTERFACE 1-1
OPERATION
DESCRIPTION
With a Clear-Com FIM-108 System, you can connect Clear-Com intercom
stations or interfaces to the central matrix using fiber-optic cables at distances of
up to 12 miles (20 km). For added convenience, Clear-Com also provides BNC
connectors, so that you can connect FIM-108 units with coaxial cables at
distances of up to 1,000 feet (300 meters).
The system consists of one FIM-108 unit at the matrix-frame end and another
FIM-108 unit at the matrix-station end. Connecting the pair of interfaces with
fiber or coaxial cable, rather than with the standard 4-wire twisted copper, gives
you advantages such as increased security from electromagnetic and RF
interference, flexibility in equipment placement, ease of maintenance, and often,
reduced cost.
Clear-Com provides three versions of of the FIM-108 interface:
•AnFIM-108D interface pair connects over two single-mode fiber-optic cables
—one cable for each direction of the signal flow. You also have the option of
connecting the units with two coaxial cables, again one cable for each direction
of the signal flow.
•AnFIM-108M interface pair connects over one multimode fiber-optic cable.
The send and receive signals are combined using wave-dimension multiplexing
(WDM) so that both directions of the signal flow can transmit over one
fiber-optic cable. You also have the option of connecting the units with two
coaxial cables, one cable for each direction of the signal flow.
•AnFIM-108S interface pair connects over one single-mode fiber-optic cable.
Like the FIM-108M unit, the FIM-108S unit combines the send and receive
signals through wave-dimension multiplexing (WDM), so that both directions
of the signal flow can transmit on one fiber-optic cable. As with the other
versions, you can optionally connect the units with coaxial cable.
Table 1: Summary of FIM-108 Fiber-Optic Connection Options
NOTE: Throughout this manual the interface will be referred to generally as the
“FIM-108 interface.” The D, M, and S designations will only be used when it is
necessary to distingish between the three versions of the interface. When you see the
term “FIM-108 interface,” you can assume that the text refers generally to all versions.

fiber optic or coaxial cable.
With fiber-optic cable, you
can place the stations at
distances of up to 12 miles
(20 km) from the central
frame.

CONNECTING INTERCOM STATIONS TO THE CENTRAL MATRIX
The Clear-Com FIM-108 system transmits audio and data signals from up to eight intercom units to the matrix frame
through the process illustrated in Figure 2. For the purposes of simplification, the illustration shows only one direction
of the signal flow, while in reality the opposite direction of signal flow occurs in a a similar fashion and simultaneously,
so that the system always transmits in full-duplex mode.
Figure 1: Connecting Intercom Stations to the Central Matrix
Matrix Plus intercom stations transmit analog audio signals and digital data signals to the first FIM-108 unit via
copper cable terminated with RJ-45 connectors.
The first FIM-108 unit converts the analog audio signals to digital audio signals through an analog-to-digital
converter (ADC) located on the FIM-108 unit’s main circuit board.
The first FIM-108 unit then multiplexes (combines) the digital audio signals with the already digital data signals.
The first FIM-108 unit then converts the multiplexed digital signal into an optical signal.
The first FIM-108 unit then transmits the optical signal over up to 12 miles (20 km) of fiber-optic cable (or
1,000 ft. of coaxial cable) to the second FIM-108 unit, where a similar but reverse process occurs to convert the
signal back to its original format.
The second FIM-108 unit converts the received optical signal to a digital signal.
The second FIM-108 unit then “demultiplexes” (separates) the digital signal back into its separate audio and data
signals for each intercom unit.
The second FIM-108 unit then converts the digital audio signals for each intercom station to analog audio signals
by sending the signals through a digital-to-analog converter (DAC) located on the FIM-108 unit’s main circuit
board.
The second FIM-108 unit then transmits the analog audio and digital data signals for each intercom station to
the central matrix over copper cable terminated with RJ-45 connectors.
The central matrix receives the intercom stations’ audio and data signals in the same format in which they were
originally sent by the Matrix Plus 3 intercom stations.
