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.

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.
