CONNECTING MATRICES WITH
FIBER-OPTIC CABLE
Each fiber card link consists of a front card with various status
indicators and a rear card with two Duplex LC Terminated fiber optic
connectors (TXVRA and TXVRB). The fiber cards use 9/125µ Single
Mode fiber optic cables. On the rear card the TX1/RX1 connector is
used for the main ring and the TX2/RX2 connector is used for the
secondary ring. Single mode 9/125µ fiber optic cable should be used
for connections and the matrices should be wired up with the system
with the lowest I/P address being system 1.
The standard maximum node length is 10km but other distances are
available to special order.
The order of the fiber optic cable connections is reversed between the
front and rear panels. On the front panel the primary connection is the
upper set of indicators but on the rear panel it is the lower connector.
Similarly the secondary connection is the lower set of indicators on the
front panel but the upper connector on the rear panel. Care should be
taken when connecting or disconnecting the cables to ensure that they
are connected correctly and not reversed.
Normally a protective plug is fitted to the fiber connector sockets to
protect them from damage or the entry of foreign materials. These
should only be removed in order to fit the fiber optic cable and replaced
if the cable is unplugged.
WIRING THE MATRIX TO INTERCOM
PANELS
Eclipse uses a 4-pair (analog) or single-pair (digital) wiring scheme
between the frame and panels. All Eclipse panels have built-in RJ-45
connectors.
4-PAIR ANALOG
Four-pair analog wiring is done with shielded CAT5 RJ-45 cable.
• Pair 1 transmits analog audio from the matrix to the panel.
• Pair 2 transmits digital data from the panel back to the matrix.
• Pair 3 transmits audio from the panel to the matrix.
• Pair 4 transmits digital data from the matrix back to the panel.
