3.7 Cable Installation

Fiber Cabling

1. Install a duplex multi-mode fiber from the radio to the network termination

equipment (switch or router with 1000Base-SX port). The cable should be looped

around the inside of the enclosure to provide strain-relief. Do not connect the fibers

to the radio’s fiber ports at this time.

The connectors on the radio end of the fiber require simplex LC connectors; the

connectors on the switch/router end should mate to the network equipment.

Note: The simplex LC connectors for the radio need to be inserted individually

through the 3/4” conduit water tight connector fitting on the radio, as there is not

sufficient room for both to fit through at the same time if connected with a duplex

clip. If a duplex clip is used, it can normally be temporarily removed to complete

the installation.

2. Connect fibers at the network equipment. It is important not to connect the fibers

to the radio until after aligning the radio as the radio performs an automatic

calibration once the fiber is inserted into the radio and this calibration will not

operate properly if the radio is not properly aligned.

Power Cabling

. Select indoor location, with easy cable routing to the radio, for the AC power

adaptor. Normally it is convenient, but not required, to place the adaptor near the

network termination equipment.

2. Ensure the DC wire used is 14-gauge type and no longer than 125 meters; or 12-

gauge and no longer then 200 meters.

3. Connect the provided DC Connectors onto the 14-guage wire using a

splicing/crimping tool. For the use of 12-gauge wire it may be necessary to trim a

few strands from the ends of thicker stranded cables to more easily fit the crimp

connectors.

4. Install the DC power cable and attach to the AC adaptor using the supplied crimp

connectors. Do not connect the power jack to the radio at this time.

5. IMPORTANT: Be sure to first connect the DC power crimp connectors before

inserting the power plug into the power jack in the radio. No sparks should be

expected with the new two conductor (green) power connector.
