CONNECTING FIBER-OPTIC CABLE TO THE FIM-108
Figure 2: ST Optical Connectors on an FIM-108 Unit’s Rear Panel
Refer to Figure 2 before connecting the optical fiber to the ST optical connectors
on the FIM-108 unit’s rear panel.
The FIM-108 is compatible with industry standard ST-type connectors.You may
use installed backbone cables or dedicated cables with it.
Always follow the connector manufacturer’s directions when fastening a
connector to the cable.
On a two-fiber system, connect the cables so that:
• transmitter ST
A
at one end connects to receiver ST
B
at the other end, and
• transmitter ST
B
at one end connects to receiver ST
A
at the other end.
On a one-fiber system, connect the fiber optic cable to the ST
A
at each end.
Figures 3 and 4 illustrate the entire wiring scheme for the FIM-108 system.
Figure 3 illustrates the wiring for a two-fiber system (FIM-108D) and Figure 4
illustrates the wiring for a single-fiber system (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. The maximum length for CAT-5
cables is 10,000 feet (3 km).
