Teko Telecom Modular Coverage and Capacity System - General 1.
Description
Teko Telecom Coverage and Capacity Systems are exible multi-band multi-operator Systems
that provide a wide range of solutions to extend both indoor and outdoor cellular coverage
in shadow areas -where the RF signal is not available- and to increase capacity in indoor and
outdoor hot spots -where the operators need dedicated coverage.
Modular design is a key feature of Teko Telecom Systems: it oers exible conguration
options to build the most suitable solution for any coverage need.
SIRIUS
Stand-alone Modular Repeaters, Optical Systems as well as integrated solutions share a unique
common platform: SIRIUS.
SIRIUS includes a wide range of active and passive components that can be assembled in a
variety of ways in order to provide easy to set-up, maintain, and upgrade products operating
in the 380 to 2700MHz frequency range.
SIRIUS components can be used in dierent Systems with dierent functionalities to meet
present needs and to allow system adaptation to changing conditions, always assuring
optimized performances.
Teko Telecom Master Unit is the core of SIRIUS modular design: it is a versatile modular rack-
based platform that controls the whole Coverage System and, depending on its components
conguration, is able to provide:
the RF interface towards the signal source (BTS, Node B, Repeater),•
the RF interface towards Service Antennas/leaky cable,•
the optical interface towards up to 144 Remote Units.•
This technical handbook describes the components of SIRIUS and how these components can
be assembled to provide Optical Systems and Modular O-air Repeaters to improve coverage
in dierent environments.

Components1.1
The components of SIRIUS can be grouped in the following categories:
Modules providing the RF interface towards the signal source1.
Point of Interface (POI) module:• is the single-band/single-operator interface towards
a BTS or NodeB. The Point of Interface module is connected to the signal source via
coaxial cable.
Digital Donor Front End Module: • is the single-band/single-operator interface towards
a Donor Antenna, providing a connection to a BTS or NodeB over an air link.
Equipment extending coverage / distributing capacity2.
Service Front End:• is the single-band/multi-operator interface towards a Service
Antenna. It provides wireless signal to the area to be covered (Modular Repeaters).
In Optical Systems the Service Front End can be used to extend coverage to the area
close to the Master Unit site.
Remote Unit:• is the multi-band/multi-operator equipment used in Optical Systems to
distribute wireless signal throughout the area to be covered (extensive areas coverage/
active DAS).
Modules providing the optical interface towards Remote Units3.
Fiber Optic Transmitter/Receiver Modules• are the optical interface between Master
Unit and Remote Units: they provide RF-to-Optical/Optical-to-RF conversion.
Master and Slave Point to Point Modules • perform the RF-to-Optical/Optical-to-RF
conversion required by the optical point to point link connecting RF Interface modules
to distant Fiber Optic Transmitter/Receiver Modules. The optical point to point link
allows a separation distance -up to 20km- between RF Interface modules and Fiber
Optic Transmitter/Receiver Modules.
Passive Modules providing distribution and ltering4.
Our passive components provide RF distribution and ltering.
The 4-way Combiner/Splitter can be used to manage up to 4 RF interface modules
operating in the same band; several models of Triplexers with built-in 1:4 Splitter/Combiner
are available to distribute signals operating over up to 3 dierent bands. The multiplexers
distribute signals operating over multiple dierent bands - up to 5 (pentaplexer); up to 6
(esaplexer).
Due to the exible conguration options of Teko Telecom Coverage and Capacity Systems,
the same passive components can be used for dierent purposes.
The • 4-way Combiner/Splitter can be used to manage either up to 4 RF interface

modules, operating in the same band (Multi-Operator Systems) or up to 4 Fiber
Optic Modules (Fiber Optic Transmitter/Receiver Modules or Master Point to Point
Modules).
The • Band Splitter/Combiner (Triplexer) with built-in 1:4 Splitter/Combiner
can be used to manage up to 3 RF interface modules or Service Front End subracks,
operating in dierent bands, and up to 4 Fiber Optic Modules. It can also manage
up to 3 four-way splitter/combiner modules each connected to multiple RF interface
modules, operating in the same band, and up to 4 Fiber Optic Modules.
Modules for the management of the System5.
The • Supervision Module allows the management of the whole Coverage System.
The • Alarm Module is an optional module that can be equipped to increase the number
of supported external alarms.
Power Supply Modules6.
The Coverage and Capacity Systems can be equipped with either AC (Universal mains,
85÷264Vac, 50-60Hz) or DC (-72÷-36Vdc) Power Supply modules.
Subracks hosting the System modules7.
Both active and passive subracks are available.
Active subracks• are provided with a backplane that allows the management and
power supply of active modules.
Passive subracks• are used to host passive modules that do not require power nor
management to function. Passive Subracks allow a reduction in the cost of the whole
system.
Forced-air cooling Subrack8.
A forced-air cooling subrack is available to ensure the air ow required for proper cabinet
installed equipment operation.
Rack cabinets for hosting the System Subracks (indoor installation) and cabinets for Outdoor
installation are also available.
A detailed description of each Component of Teko Telecom Modular Coverage and Capacity
System is provided in the following paragraphs.

Modules providing the RF interface towards the signal source1.1.1
Point Of Interface Modules•
Point of Interface modules are used in Optical Systems to interface any kind of operator signal
source -pico/micro/macro BTS or NodeB: each Point of Interface module is connected to a
single mobile operator/ mobile band signal source via coaxial cable.
Optical Systems can be equipped with one Point of Interface or more Point of Interface
modules to make multiple congurations available: single operator (single band / multi-band)
and multi-operator (single-band / multi-band).

Modules providing the optical interface towards Remote Units1.1.3
Fiber Optic Transmitter/Receiver Modules•
Fiber Optic Transmitter/Receiver Modules are the optical interface between Master Unit and
Remote Units: they provide RF-to-Optical/Optical-to-RF conversion. They are connected to
Remote Units via single mode optical bers, with Uplink and Downlink signals transmitted
over the same bre (Wavelength Division Multiplexing -WDM technology).
Dierent congurations are available: a single Fiber Optic Transmitter/Receiver Module can
be equipped with 1 Optical Transmitter and 1 Optical Receiver (10dB optical link budget, up
to 20km distance - 12.4 miles), or 1 Optical Transmitter split by 2 and 2 combined Optical
Receivers (10dB optical link budget, up to 20km distance- 12.4 miles), or 1 Optical Transmitter
split by 4 and 4 combined Optical Receivers (6dB optical link budget, up to 12km distance -
7.5 miles).
The Fiber Optic Transmitter/Receiver Module in 1:4 conguration can manage up to 4 Remote
Units.
The Fiber Optic Transmitter/Receiver Module in 1:1 conguration is able to drive up to 5
cascaded Remote Units with dierent wavelengths in Up-link.

(TTRU models).
Fiber Optic Receivers convert uplink optical signals from Remote Units into RF. They operate
in the third window (Optical wavelength 1490 ÷ 1570 nm).
Each Fiber Optic module is controlled by a microprocessor which provides the following data
to the Supervision Module:
optical power received by each optical receiver, -
Downlink attenuator and Uplink attenuator attenuation setting (0 ÷ 15dB), -
received optical power alarms. -
An auto-levelling functionality (AGC) compensates up to 10dB optical link loss in order
to guarantee constant gain over dierent optical budgets. This feature simplies system
installation, makes commissioning quick and easy and avoids eld adjustments.

Master and Slave Point to Point Modules•
Master and Slave Point to Point Modules provide an optical point to point link allowing a
separation distance -up to 20km- between RF interface subracks and optical subracks.
The point to point link is suitable when the signal source (BTS, Node B, Repeater) is located
far from the area to be covered or when the same optical system provides coverage to several
separate buildings; in these applications the point to point link allows the transmission of
signals from/to a group of remote units over a single optical bre, thus providing a signicant
reduction in the number of ber optics running long distances.
The point to point link requires the RF interface subracks to be equipped with Master Point
to Point modules and the remote optical subracks to be equipped with Slave Point to Point
modules. The RF Interface subracks can be equipped with up to 4 Master Point to Point modules
for the management of up to 4 optical subracks, installed in dierent remote locations.
Master Point to Point Module Slave Point to Point Module
Each Master Point to Point Module is connected to a Slave Point to Point Module, equipped in
a remote optical subrack, via a single optical bre (single-mode SMR 9/125).
