Compliance with IC
Use only for both in-building and outdoor applications in sites located in regions (Canada) that
require IC compliance.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada.
It is the responsibility of proponents and operators of antenna system installations to ensure that all radio
communication and broadcasting installations comply at all times with RSS RF exposure requirements and
Health Canada’s Safety Code 6, including the consideration of combined effects of nearby installations within the
local radio environment.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when
multiple carrier signals are present, the rating would have to be reduced by 3.5dB, especially where the output
signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means
of input power or gain reduction and not by an attenuator at the output of the device.
This radio transmitter 8749A-A218SERIES has been approved by Industry Canada to operate with the antenna
types listed in sections 2.2 and 2.3 with the maximum permissible gain and required antenna impedance for
each antenna type indicated. Antenna types not included in sections 2.2 and 2.3, having a gain greater than the
maximum gain indicated for that type, are strictly prohibited for use with th is device.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada.
Il est de la responsabil ité des promoteurs et ex plo i tants d'installati o n s de systèmes d'anten n es af i n de s'a s su r er
que toutes les installations de radiocommunication et de radiodiffusion respectent en tout temps au matière
d'exposition RF RSS et code de sécurité 6 de Santé Canada, y compris l'examen des effets c ombinés des
installations avoisinantes dans le milieu de la radio locale.
Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir
le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire à l'établissement d'une communication satisfaisante.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec
porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3.5dB,
surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes
adjacentes. Une telle réduction doit porter sur la puissance d'entrée ou sur le gain, et ne doit pas se faire au
moyen d'un atténuateur raccordé à la sortie du dispositif.
Cette radio émetteur-8749A A218SERIES a été approuvé par Industrie Canada pour fonctionner avec les types
d'antenne énumérés dans les sections 2.2 et 2.3 avec le gain maximal admissible et l'impédance d'antenne
requise pour chaque type d'antenne indiqué. Types d'antennes non comprises dans les sections 2.2 et 2.3, ayant
un gain supérieur au gain maximum indiqué pour ce type, sont strictement interdits pour une utilisation avec cet
appareil.

General Safety Warnings Concerning Use of System
Always observe standard safety precautions during installation, operation and maintenance of this product.
Caution labels!
Throughout this manual, there are "Caution" warnings. "Caution" calls
attention to a procedure or practice, which, if ignored, may result in injury or
damage to the system, system component or even the user. Do not perform
any procedure preceded by a "Caution" until the described conditions are fully
understood and met.
Danger: Electrical Shock
To prevent electrical shock when installing or modifying the system power
wiring, disconnect the wiring at the power source before working with un
insulated wires or terminals.
Caution: Safety to
personnel
o Before installing or replacing any of the equipment, the entire manual
should be read and understood.
o The user needs to supply the appropriate AC or DC power to the repeater.
Incorrect power settings can damage the repeater and may cause injury
to the user.
o Please be aware that the equipment may, during certain conditions
become very warm and can cause minor injuries if handled without any
protection, such as gloves.
Caution: RF Exposure
o RF radiation, arising from transmitter outputs connected to AWL’s
equipment, must be considered a safety hazard.
o This condit i on might only occur in the event of cable disconnection, or
because a ‘spare’ output has been left un-terminated. Either of these
conditions would impair the system’s efficiency. No investigation should be
carried out until all RF power sources have been removed. This would
always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50 ohm, and that of free space at
377 ohm, which would severely compromise the efficient radiation of RF
power. Radio frequency burns could also be a hazard, if any RF power
carrying components were to be carelessly touched!
o Antenna positions should be chosen to comply with requirements (both
local & statutory) regarding exposure of personnel to RF radiation. When
connected to an antenna, the unit is capable of producing RF field
strengths, which may exceed guideline safe values especially if used with
antennas having appreciable gain. In this regard the use of directional
antennas with backscreens and a strict site rule that personnel must
remain behind the screen while the RF power is on, is strongly
recommended.
o Where the equipment is used near power lines or in association with
temporary masts not having lightning protection, the use of a safety earth
connected to the case-earthing bolt is strongly advised.
Caution: Safety to
equipment
o When installing, replacing or using this product, observe all safety
precautions during handling and operation. Failure to comply with the
following general safety precautions and with specific precautions
described elsewhere in this manual violates the safety standards of the
design, manufacture, and intended use of this product.
o Changes or modifications not expressly approved by the par t y re spo n sible
for compliance could void the user’s authority to operate the equipment.
o Cobham Wireless assumes no liability for the customer's failure to comply
with these precautions. This entire manual should be read and understood
before operating or maintaining the repeater.
Warning: Restricted Access
Location
Access to the unit installation location is restricted to SERVICE PERSONNEL
who have been instructed on the restrictions and the required precautions to
be taken.

Attention: Electrostatic
Sensitivity
o Observe electrostatic precautionary procedures.
o ESD = Electrostatic Discharge Sensitive Device.
o Static electricity can be conducted to the semiconductor chip from the
centre pin of the RF input connector, and through the AC connector pins.
When unpacking and otherwise handling the repeater, follow ESD
precautionary procedures including use of grounded wrist straps,
grounded workbench surfaces, and grounded floor mats.
Caution: Class 1 Laser
The repeaters described in this manual are equipped with class 1 lasers, as per
definition in EN 60825-1
Caution - Un-terminated optical receptacles may emit laser radiation. Exercise
caution as follows:
o Do not stare into beam or view with optical instruments. Optical
transmitters in the Fiber optic converter can send out high energy invisible
laser radiation. There is a risk for permanent damage to the eye.
o Always use protective cover on all cables and connectors which are not
connected.
o Never look directly into a Fiber cable or a connector.
o Consider that a Fiber can carry transmission in both directions.
o During ha nd l i ng of laser cables or connections, e nsure that the source is
switched off.
o Regard all open connectors with respect and direct them in a safe
direction and never towards a reflecting surface. Reflected laser radiation
should be regarded as equally hazardous as direct radiation.

1 INTRODUCTION
The Multi-Band Fiber optic fed system encapsulates solutions for single or multi-operator use. It
offers seamless coverage in any indoor environment such as tunnels, subways and large buildings.
Signals are coupled off from a nearby base station using an Optical Master Unit (OMU) and then
distributed via Fiber to one or more MBF-40 repeaters.
The MBF-40's high output power allows for greater coverage whilst deploying fewer units. Even
though providing high out put power, the MBF-40 uses convect ion cooling, subsequently increasing
the repeater's MTBF.
These remote units can be installed at a distance of up to 20 km fr om the base stat ion site, offering
great flexibility when provi ding RF coverage in areas where off air t ransmission is not a preferable
solution.
A distributed antenna system (DAS) can be used to distribute the signal throu ghout the area to be
covered.
Cobham Wireless can provide a complete solution including design, site surveys and equipment
related to the POI (Point Of Interface) such as combiners, filters, cross band couplers, etc.
Note the following:
• For sites requiring FCC compliance, the system can only be installed for in-building applications.
• For sites requiring IC compliance (Canada), the system can be installed for both in-building and
outdoor applications.

1.1 Features and Capabi lities
• High-power indoor/outdoor unit dual-band model, supporting SMR at 700/800 MHz.
• Output power at the antenna (composite): 37dBm.
• Very low noise factor - minimizes interference to BTS and increases high speed data throughput
• Single or Dual Fiber feed models available
• Remote commissioning and monitoring:
• Via OMU II intuitive We b GUI
• Via AEM – no local setup required
• SNMP v1/v2c support
• Plug-and-Play: Automatic detection and Optical Gain Setting via the OMU
• Automatic Level Control (ALC) - provides constant gain in both uplink and downlink paths
according to the defined maximum outp ut level
• Backup battery for ‘last gasp’ indication (sending fault error before power failure)
• Optional - two internal power supplies provided for some models ensure robust unit operation
• Power source: 115VAC or -48V power (model dependent)
1.2 ALC
The repeater has a constant gain in both uplink and downlink paths. The repeater has a defined
maximum output level. If the input signal amplified by the gain set exceeds the set output limit, an
ALC (Automatic Level Control) loop is activated. This ALC ensures that the amplifier does not add
distortion to the radio signal. Below are examples of the ALC function for one and two carriers.

1.3 Operating Temperature
The MBF-40 is designed primarily for multi carrier purposes. If the repeater is run at full output
power over a long period of time, additional, external cooling may be required; this can take the
form of air-conditioning or an external fan assembly.
NOTE: The repeater is equipped with a power management function that steps down the power and, if needed,
fully shuts down the amplifier chains until temperature reaches normal values.
1.4 MBF-40 Management Web GUI
MBF-40 is remotely commissioned a nd monitored via an OMUII session. Local access to the unit is
not required for commissioning.
Additional configuration and troubles hooting optio ns a re a vailable via a dire ct co nnection to t he MBF40 IP address. A direct session can be opened locally or remotely.
NOTE: Direct remote communication requires connecting the MBF-40 to an Ethernet network.
1.5 MBF-40 Basic Interfaces
The MBF unit provides several types of interfaces:
• Lock and screws for protection and security
• External service antenna and GND connections
• Internal connections for power, Fiber optics and alarm cables routed via openings in the front
panel.
• Internal USB and Ethernet connections for local setup via Web GUI

2.2 Infrastructure and Cabling Considerations
This section includes the following information:
• RF and grounding cabling guidelines
• Power requirements
• F/O installation guidelines
• EMV protection requirements
• External alarm and relay considerations
• Criteria for selecting the repeater location
2.2.1 RF Cable Installation Guidelines
• For all coaxial connections to/from the Repeater – use high performance, low-loss, 50 ohm
coaxial communication cables.
• All cables shall be weather-resistant type.
• Cable length – determined by the Repeater installation plan. When calculating the cable length,
take into account excess cable slack so as not to limit the insertion paths.
• Make sure the cable and the connector are compatible. Using cables and connectors from the
same manufacturer is helpful.
• All connectors must be clean and dry.
• Waterproof all outdoor connections using silicon, vulcanizable tape or any other suitable
substance, as moisture and dust can impair RF c ha r acteristics
• Make sure enough room has been allocated for the bending radius of the cable. RF cables must
not be kinked, cut or damaged in any way.
• Connect the RF cable to the antenna tightly but without damaging threads.
• Fasten cable tightly to cable ladder or aluminium sheet.
• For short length feeder cables, use 1/2”; for longer feeder cables, use 7/8”. Choose thicker coax
cables for lower attenuation. Minimize the length of the coax cables to reduce attenuation.
• Use jumper cable for easy installation. The RF coaxial cable can be substituted at each end with
a jumper cable.
2.2.2 Grounding Wires Requirements
WARNING!!! Do not use the repeater grounding bolt to connect external devices.
Requirements for grounding wires
• Ensure that good grounding protection measures are taken to create a reliable repeater site.
• Make sure to use adequately dimensioned grounding cables. The minimum recommended
conductive area for a grounding cable is 16mm
2
• Make sure the grounding p roduct used is suit able for the type and size of used cable.
• Connect the repeater box bolt to the same ground.

2.2.3 Power Requirements
This section describes the circuit breaker requirements and power cabling and connection
considerations for 230VAC power source and for -48VDC power sources.
2.2.3.1 Circuit Breaker Requirements
The power connections to the unit are hard-wired. To disconnect the unit (either manually or
automatically in case of overcurrent), it is required to install a circuit breaker
on the wall near the
unit
, at an easily accessible distance and location from the unit.
Circuit-breaker minimum requirements
• 115 VAC - Maximum current 10A
• Needs to be SAFETY approved
• Use only a two-pole disconnect device.
• Requires minimum contact separation of 3mm.
• Install on the wall near the unit.
2.2.3.2 115 VAC Power Source Cable Requirements
Cable requirements:
• Cable should be NRTL (safety) approved with a minimum of 14AWG or 2.5mm2 per conductor,
and maximum of 12AWG or 4mm
2
per conductor.
• For safety, the GND cable must be 10mm longer than the Phase and Neutral cables.
2.2.3.3 -48V Power Source Connection Requirements
Note: The -48VDC version of the power supply is designed to turn off if the supply voltage falls below -36V
(±1V), not to drain the feeding battery. It will turn on again as the supply voltage reaches -43V (± 1V).
-48V power supply requirements
The 48VDC power supply must comply with SELV requirements, as defined in EN60950, which
implies double isolation. The output power needs to be 48VDC +25%/-15 %. The maximum input
current is 8A.
Recommended cable areas for 48VDC
Distance Cable Area
0 - 10 meters between repeater and
power supply
2,5 mm²
10 – 50 meters between repeater
and power supply
4 mm²
Over 50 meters between repeater
and power supply
Recommendation is to reconfigure the installation, or to make
special arrangements to increase cable area

2.2.5 EMV Protection
CAUTION! Ensure good EMV protection. If insufficient Electromagnetic Protection is
provided, or if EMV measures are not taken, warranties issued by Cobham Wireless are not
valid.
Connect the lightning protection
The lightning hazard to electric and electronic equipment consists in the interferences of direct
lightning current in fections and high surge volt ages induced by the electroma gnetic field of nearby
lightning channels or down conductors. Amplitudes from cloud-to-earth lig htning amounts t o several
10kA and may last longer t han 2m s . T he da ma ge caus e d de pe nds on t he e nergy involved and on t he
sensitivity of the electronics systems.
Ensure that lightning protection measures are taken to create a reliable repeater site. Protect all
coaxial cables and power cables from the tran sients caused by lightning. Fit all cables wit h suitable
lightning protection devices.
Figure 2-1: Example of EMV protection for a repeater system
For detailed information please refer to IEC 61024-1 and 61312-1 for international standards for
protection of information systems against LEMP (Lightning Electromagnetic Pulse), including radio
transmitters. They d efine prop er planning , installation and inspection of effective lig htning protection
systems.
Cobham Wireless rep eaters comply with t he EN standar d ETS 301 498-8 which stipulat es demands
on lightning/surge protection for typical infrastructure telecom equipment installations.
Several lightning protection devices sho uld be use d in ser ies with decli ning t hreshold voltag es to help
