5.8 Installing the RUs
5.8.1 Pre-installation actions
Prior to installing the RUs, it is important that the site has bee
n
sufficiently to accommodate the equipment. Particular attention sh
o
to the following:
• Fibre optic cable lengths and type. The cables should be of a
weight, suitable bend radius and capable of withstanding tensi
o
installation. The length of the cables will be determined by
t
coverage attainable by the strategic location of the RUs withi
n
complex.
• Fibre optic cable terminations. These can be supplied suitably
(cable lengths need to be known in this case) or cables can be
terminations and then, by cable splicing, short cables provide
connectors can be attached.
• The fibre optic cable connectors used must be angle-polished t
connectors. Fusion splices to connect fibres are also suitable
• RU locations. The most efficient manner for locating RUs is t
h
minimum number of RUs for optimum cell coverage. The position
RUs must ensure the maintenance of their operating temperature
• Power supply availability.
• All cables must be clearly labelled.
• The system configuration must be adequately documented.
