AR/GE/FE/U 80/80X Installation Manual 2.6 Cabling The installation site should be inspected to determine the run paths for the fiber cable and power cable from the radio equipment to the termination point. Locations for roof penetration should be identified. The routing and securing of all cables should conform to all applicable codes and requirements. Depending on the likelihood of damage due to foot traffic or equipment movement, cabling conduit may be required. The maximum cable run length as specified for the equipment being installed must not be exceeded, refer to Table 2.61 and 2.62 for cable types and limitations. The radio requires LC type connectors on duplex multimode fibers to properly connect between the radio and the users network equipment. Singlemode fiber connections are not supported for use with the standard product. The network equipment end of the fibers should be terminated with connectors that match the user’s network equipment fiber interface. Table 2.61: Maximum Fiber Length Fiber Cable Length Cable Type Up to 270 meters 62.5/125 μm Up to 500 meters 50/125 μm The 80GHz radio includes a 100240 VAC power adaptor, suitable for indoor operation only, that converts the AC voltage from a standard electrical outlet in the wall to DC voltage. For outdoorrated power supply options, contact BridgeWave customer service. The radio requires a minimum of 15.0 VDC at the connector on the radio unit (24.0 VDC maximum) to function properly. When planning the cable run from the indoor AC power adaptor to the radio unit, it is required to use the cable gauge (AWG) indicated below to ensure adequate voltage at the radio. The indoor and outdoor portions of the DC power cabling must conform to all respective indoor and outdoor national and local electrical and building codes; note that requirements may differ for the indoor and outdoor portions of the cabling and that a grounded surge protector is normally required at the point where the cable enters the building. The DC power cabling must consist of two 12 or 14 gaugestranded conductors based on the required cable run length. Table 2.62: Minimum DC Cable Size DC Cable Length Up to 125 meters Up to 200 meters Conductor Size 14 AWG (2.5mm²) 12 AWG (4mm²) Figure 2.61 shows a standard 14gauge wire that has been fitted with the power connectors (provided) for the radio’s internal power supply necessary to mate with the (not provided) DC power 5 58000519 rev.

AR/GE/FE/U 80/80X Installation Manual cables. A standard crimping/splicing tool (not provided) is required to terminate the power connectors onto a 1412gauge cable required for use with the 80GHz. On the radio end no connectors are required; simply screw terminals to appropriate polarity. The DC power cable should be fed into the connector on the casing first and then the green connector attached to the radio after making a strain relief coil around the electronic housing.

(Right) DC 14gauge cable from the power supply end. 2.7 Grounding & Lightning Proper grounding of the outdoor equipment reduces electromagnetic interference, provides lightning protection, and protects against electrical discharge. Using improper techniques in lightning prone geographic areas may pose a danger to local personnel. The source and connection points for the buildingtoearth ground in the vicinity of the antenna location should be determined. In addition to grounding the equipment, BridgeWave strongly recommends, and local building codes may require, the DC electrical cable to be protected from electrical surges by a surge suppressor. The surge suppressor must be installed at the point where the DC electrical cables exit/enter the building. 6 58000519 rev. D
