1.2 OR System Description
1.2.1 General Description
The ADC OR system consists of two units, a Host unit, installed close to the
BTS, and a Remote unit, installed in the remote site. This integrated structure
provides the advantage of easy installation and maintenance.
The Host Unit contains the following main units:
• Optical transceiver
• Signal processing and controller
• Power supply
Optical transceiver
The optical transceiver includes a transmitter and receiver units. The
transceiver converts the FWD RF signals into light wave signals, which are
then sent over optical fiber. The transceiver also reconverts the RVS light
waves signals back to RF.
The signals passing through the optical fiber include also the M&C signals.
This enables M&C of the Remote unit remotely from the Host and vice-versa.
Signal Processing and Controller
The RVS and FWD RF signals pass through the LPU, managed by the
internal control system. The control system sets signal power levels, filters,
and sets the selectable RF channels (if applicable).
A local connection to the system enables M&C of each settable component.
The control software is described in Chapter 3.
The system controller in the LPU is monitoring and logging all activity changes
and alarms.
