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.
Optical Connectors
A high-powered LED coupled to an optical fiber generates the FIM-108 unit’s
optical output. A bulkhead-type ST connector on the FIM-108 unit’s rear panel
connects to the transmission fiber. The transmission fiber must be matched to
the fiber pigtail type specified at the time of manufacture.
The input uses a pin diode and amplifier to convert the optical signal back to an
electrical signal.
The optional single-fiber system uses a wavelength-division multiplexer to
combine and then separate the two colors used.
Coaxial Connectors
Each version of the FIM-108 unit has two BNC connectors for connecting two
75-Ohm coaxial cables.
Power Connector
A UL- and CE-listed external in-line power supply, with a 3-pin connector,
provides the required 12 VDC to operate an FIM-108 unit.
