FIM-108
The FIM-108 is a 1-RU optical fiber interface for use with the Clear-Com Matrix Plus
and Eclipse digital intercom systems. Each pair of fiber interfaces allows up to eight
digital matrix intercom stations to be remotely connected to the matrix card frame via
optical fiber or coaxial cable.
This transmission capability allows a set of intercom stations to be located remotely
from the matrix frame using existing fiber cabling, or can be used to temporarily locate
stations via fiber in event production applications. Stations may be connected to the
matrix frame at fiber lengths of up to 12 miles (20 km). The use of fiber for long runs
eliminates all types of electromagnetic and RF interference to the signal.
For additional convenience, two coax connectors are also available on the rear panel,
allowing runs of over 1,000 feet (300 meters) on standard Belden 8281 or equivalent
coax cable.

FIBER CABLE
( Up to 12 miles, 20 km )
Two fiber interface units are used for each eight connections – one at the matrix
frame end and one at the remote station end. For each connection between frame
and interface, a port is connected to one of the eight “matrix” connectors on the rear
of the interface using RJ-45 connectors and 4-pair CAT-5 cable. At the other end,
each station is connected to one of the “station” connectors on the rear of the second
interface using the same type of cabling. Once connected, the matrix frame “sees”
the stations just as if they were directly connected via CAT-5 cable.

ONE- AND TWO-FIBER VERSIONS
SPECIFICATIONS
Two versions of the interface are available. The FIM-108D
uses two fiber optic cables to make the connection
between the interfaces — one for each direction of the
signal flow. When cable availability is limited, the
optional FIM-108S uses wave-dimension multiplexing
on a single fiber for bidirectional transmission.
Audio
TRANSMISSION AND OPERATION
The FIM-108 interface that is connected to the digital
matrix frame receives the audio and data that is directed
to the individual stations that are connected on the other
end of the fiber — each going to its own RJ-45 connector. The audio signals are sampled at 48K and timesequenced, and the RS-422 data from each is also
collected. The consolidated signal is sent as an 18-bit
digital stream through an outgoing fiber, in the case of
the D-version, or is multiplexed on a single fiber in the
S-version.
Incoming data from the stations is decoded by the interface and sent to the correct RJ-45 connector and then
back to the matrix frame. The process is reversed by the
FIM interface at the station end. For the audio portion of
the signal, the transmission is flat (+/- 0.2 dB) to 20 kHz,
with a signal-to-noise ratio greater than 90 dB.
