DESCRIPTION
With a Clear-Com FIM-102D 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).
The system consists of one FIM-102D at the Matrix-frame end and another FIM-102D unit at the Matrix-station end.
Connecting the pair of interfaces with fiber 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.

CONNECTING INTERCOM STATIONS TO THE CENTRAL MATRIX
The Clear-Com FIM-102D system transmits audio and data signals from 1 or 2 intercom stations or interfaces to the
Matrix frame through the process illustrated in Figure 2.

FIM-102D FIBER INTERFACE 1-3
1-4FIM-102D FIBER INTERFACE
1. Matrix Plus intercom stations transmit analog audio signals and digital data signals to the first FIM-102D unit via
copper cable terminated with RJ-45 connectors.
2. The first FIM-102D unit converts the analog audio signals to digital audio signals through an analog-to-digital
converter (ADC) located on the FIM-102D unit’s main circuit board.
3. The first FIM-102D unit then multiplexes (combines) the digital audio signals with the already digital data signals.
4. The first FIM-102D then converts the multiplexed digital signal into an optical signal.
5. The first FIM-102D then transmits the optical signal over up to 12 miles (20 km) of fiber-optical cable to the
second FIM-102D unit, where a similar but reverse process occurs to convert the signal back to its original format.
6. The second FIM-102D unit converts the received optical signal to a digital signal.
7. The second FIM-102D then “demultiplexes” (separates) the digital signal back into it’s separate audio and data
signals for each intercom unit.
8. The second FIM-102D 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-102D unit’s main circuit board.
9. The second FIM-102D 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.

10. 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.
WARNING: Always use extreme caution with fiber-optic equipment. Never look directly into the light port or into
the end of the optical fiber while either FIM-102D unit is operating. Even if you do not see visible light, eye
damage is possible.
CIRCUIT DESCRIPTION
Analog-to-Digital Converters High speed analog-to-digital converters for each audio channel.
Multiplexer Sequentially presents two RS-422 digital inputs and two digitized audio signals from the A/D converters to the
optical output driver.
Demultiplex-er Takes sequential digital signals from the pin diode and separates them into 4 separate lines: two to the D/A
converters and two to the RS-422 transmitters.

CONNECTING INTERFACE MODULES TO THE CENTRAL MATRIX
With a pair of FIM-102D units you can also remotely connect Clear-Com rack-mounted Matrix interface modules to
the central Matrix. For example, using a Clear-Com CCI-22 dual party-line interface at one end, you can connect two
independent, external 2-wire party line systems to the central Matrix from a distance of up to 12 miles (20 km). Or,
with a Clear-Com TEL-14 Telephone Interface Module, you can send telephone audio to the central Matrix over a
secured interference-free fiber-optic line. By using a Clear-Com FOR-22 4-wire interface module, you can send 4-
wire audio plus transmit keying over a fiber-optic line. You can also use a Clear-Com EF-1M to interface 2-wire
Clear-Com or RTS party lines to the central Matrix over a fiber-optic link.
Figure 2 shows a system with connected interface modules.
