DESCRIPTION
Fiber-Span’s Headend Repeater Unit
(HRU) is similar in functionality to a Bidirectional Amplifier, or Signal Booster
Device as the FCC refers to it, with one
minor difference: the HRU features an
extra set of RF ports designed specifically
to interface with a Fiber-based signal
distribution system. These base-toportable (downlink) and portable-to-base
(uplink) ports couple RF signals off the
downlink path and onto the uplink path
before they reach the internal duplexer.
The advantage here is that no external
directional coupler or duplexer is
required to split TX from RX.
This design approach takes the hassle
out of connecting to a fiber Distributed
Antenna System (DAS) by eliminating
the need for an external duplexer
and coupler, which can add up to
considerable cost savings depending on
frequency separation and pass bands.
All HRUs include a
duplexed port on the portable side to
feed a traditional RF only DAS.
Fiber-Span offers a broad range of HRUs,
including channelized (narrowband)
systems, and RF-on-Fiber products to fit
most wireless applications.
The FS31HG-TETRA Headend
Repeater Unit (HRU) is part of FiberSpan’s FS3100 family of products and is
designed to deliver up to +36 dBm of
base-to-portable and portable-to-base
output power in the TETRA band. It
features high gain, low distortion Power
Amplifiers, and high Q bandpass duplexer
with 5.0 MHz passband and 10 MHz TX
to RX channel separation. Consult FiberSpan Sales for other filter configurations.
As depicted in the diagram below, when
the HRU is used to feed a Fiber DAS, a
Fiber Transceiver Unit (FTU) is required
to perform the RF-to-optical conversion
at the headend. The FTU can be
ordered in 1-port, 2-port, or 4-ports per
module, supporting up to 24 RRUs per
3U Mainframe Chassis. Multiple FTUs
may be daisy-chained to accommodate
N-port configurations, supporting
virtually any number of RRUs.
Consult Fiber-Span Sales for assistance
in determining whether a BSU may be
required for your application.
All of Fiber-Span’s FS3100 series HRUs
are supplied standard with local contact
closures for Alarm Monitoring. They are
also provided with GUI access for Alarm
Status Monitor and Control capability.
Alarms and configuration settings may be
accessed locally, or remotely via Network
Gateway connection at the Headend.
Refer to FS3100 G-Series GUI User
Guide for further details.
