1.3.6.1 RF Path
At the headend, RF signals from the RF signal sources (e.g. BTS/BDA) are conditioned by service specific (conditioner)
modules in the HEU (Headend Unit) and organized into (up to three) user configurable sectors. The conditioned RF signals are
converted to optic signals by the (wideband) OIU (Optic Interface Unit) and specific sectors are routed towards selected remote
locations according to user defined configurations.
The optic fibers at the OIU are routed to the ICU (Integrated Centralized Unit) at the remote end. From the ICU the optic fibers
are distributed along with DC to the Remote Access Units (RAU).
