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,”...
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.
Table 2: Circuits in the FIM-108 System CONNECTING INTERFACE MODULES TO THE CENTRAL MATRIX With a pair of FIM-108 units you can also remotely connect Clear-Com 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).
1 on one unit becomes the ouput of channel 1 on the other unit, and vice versa. The two FIM-108 units in the two-fiber version are identical, so the units are interchangeable.
Power On/Off Switch Link Status Light 3 Power Status Light Figure 4: Front Panel of an FIM-108 Unit Power On/Off Switch The power on/off switch locks to prevent inadvertent power turn off. To unlock the switch, pull it towards you until the lock disengages. Do not try to move the switch without first unlocking it.
Figure 5: Rear Panel of an FIM-108 Unit Audio and Data Connectors Eight separate pairs of RJ-45 connectors are located on an FIM-108 unit’s rear panel as shown in Figure 5. Each pair of RJ-45 connectors attaches an audio/data input and an audio/data ouput to the FIM-108 unit.
2. Move the lever up to turn power on, or down to turn power off. 3. Switch the power on at both FIM-108 units. The power at both units must be on for the system to function.
INSTALLING AN FIM-108 UNIT IN A RACK Clear-Com ships each FIM-108 unit ready for installion in an equipment rack. If you are not installing the units in a rack, you can remove the rack adapters by unscrewing the two #10 flat-head screws that hold each adapter in place, as shown in Figure 1.

WARNING: Do not use the FIM-108 optical output to identify cables. Never look directly into the end of the optical fiber while either end of the system is operating.
(FIM-108M or FIM-108S). CONNECTING AUDIO/DATA CABLES TO THE FIM-108 RJ-45 connectors on the FIM-108 unit’s rear panel connect the unit to audio and data inputs and outputs as shown in Figures 3 and 4. Figure 5 illustrates the CAT-5 and above cable pinout configuration.

If you are unable to resolve a problem with your FIM-108 unit, call Clear-Com Intercom Systems at (510) 496-6666 and ask for the Service Department. See the Warranty Chapter for more information. PREVENTIVE MAINTENANCE Every two years verify the adequacy of optical power at the far end of each optical fiber with an optical power meter.
GLOSSARY fiber-optic cable A fiber-optic cable consists of a glass core covered with a reflective material called “cladding” and several layers of buffer coating to protect the cable from the environment. A laser sends light pulses through the glass core to the other end of the cable.

wavelength-division multiplexing (WDM) A method of multiplexing optical signals developed for use on fiber-optic cable. Each signal is assigned a particular wavelength on the light spectrum and therefore many signals can be transmitted simultaneously without interfering with each other. 4 - 2 F I M - 1 0 8 F I B E R I N T E R F A C E...
