Site Preparation
For example, for three remote units, six fibers are required. However, to allow for future
upgrades, it is recommended to install additional optic fibers to be connected to additional
RHUs.
The following figure illustrates fiber optic routing sufficient to cover 21 floors: each group of
strands can cover three floors as illustrated below, with two strands to spare. The first group
of strands coves floors 1, 2 and 3; the next group will cover floors 4, 5 and 6 through an
additional splice box.

• For remote power supply configuration - cable bundles are routed from the main
communication room and individual wire pairs are terminated into the power feed of
individual units.
By providing power from a single distribution point, maintenance can be reduced and UPS
backup can be easily provided. The maximum distance from the source to the termination
spot is 1000 feet using 18 gauge wires.
In many locations local codes do not require power to be run through conduit if 100 watts or
less is used. Please consult the regulations in your local jurisdiction prior to deploying remote
power. When power cables require distances greater than 1000 feet 14 or 16 gauge wire
may be used.
• On each floor - the antennas are connected to the RHUs using coax cables.
