Connect optical fiber cable
The optical ports may be equipped with ST, SC or FC fiber connectors. A fiber pair is required for
operation with dual fiber models, TX is the signal output side and RX is the signal input side. Bi-directional
single fiber models combine input and output, and require only a single fiber.
Connect fiber cables to correct TX and RX ports. On dual fiber models, the TX port of on side must be
connected to the RX port of the unit at the other side. Make sure the connections for dual fiber optics are
flipped accordingly.
Do not remove fiber cable caps until you connect fiber to the unit, watch for contamination.
Connect Ethernet ports
The two Ethernet ports use standard RJ-45 connectors. The Ethernet ports are 10/100M, full/duplex,
auto negotiating. The ports have status indicators when operating. Refer to the LED indicators table for
additional information.
Connect analog phones
The Fiber Link Card combines 2 POTS channels into a single RJ-45 connector. The POTS ports use the
center 4 pins of the RJ-45 connector, which are then split out to standard RJ-11 female adapters for easy
installation. Use the included adapter cable to attach RJ-11 connectors to the POTS card.

Connect Power
The POTS system accepts a 24-48VDC local power source. The power range is identified on the top of
the card, near the power connector.
Note: The power terminals are not polarity sensitive, and power wires may be inserted into either side.
Attach the power wires to the screw down terminal on the front panel of the card. For ease of installation,
the terminal block may be removed by pulling straight out.
If removed, seat the terminal block firmly into the connector before applying power. Once power is
applied, the system will begin operating automatically.
