MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL IV User Manual Doc No. 00068UM Rev. 2.4 © Axell Wireless Ltd FCC Part 20 Warning Statement WARNING: This is NOT a CONSUMER device. It is designed for installation by FCC LICENCEES and QUALIFIED INSTALLERS. You must have an FCC LICENCE or express consent of an FCC Licensee to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. FCC Part 15 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. If not installed and used in accordance with the instructions, this equipment generates, uses and can radiate radio frequency energy. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to RF reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Repeaters must be used ONLY for in-building applications One must be aware that FCC regulation mandate that these repeaters are to be used only for in-building applications and thus feed passive or active DAS (Distributed Antenna Systems) accordingly. Unauthorized Changes to Equipment Changes or Modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment FCC RF Exposure Limits This unit complies with FCC RF exposure limits for an uncontrolled environment. This equipment must be installed and operated with a minimum distance of 32 cm between the radiator and any person’s body. Antenna Installation Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on an indoor permanent structure. The maximum antenna gain for indoor operation is 13 dBi. Antennas having a gain greater than these are strictly prohibited for use with this device. In indoor applications the antenna must be installed at a minimum separation distance of 32 cm from all nearby persons.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 V Compliance with IC 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. 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 3.5 dB, 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. 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. 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 3.5 dB, 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. Cet appareil est conforme aux limitations de la norme IC RSS-102 concernant l’exposition aux radiations dans un environnement non contrôlé. Cet appareil doit être installé et utilisé avec une distance minimale de 32 cm entre l’antenne et le corps de l’utilisateur.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL VI User Manual Doc No. 00068UM Rev. 2.4 © Axell Wireless Ltd General Safety Warnings Concerning Use of This 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 Before installing or replacing any of the equipment, the entire manual should be read and understood. 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. 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 RF radiation, arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard. This condition 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, that 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! 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. 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.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 VII Caution: Safety to equipment 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Axell 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 Axell unit installation location is restricted to SERVICE PERSONNEL and to USERS who have been instructed on the restrictions and the required precautions to be taken. Attention: Electrostatic Sensitivity Observe electrostatic precautionary procedures. ESD = Electrostatic Discharge Sensitive Device. 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: • Do not stare into beam or view with optical instruments. Optical transmitters in the fibre optic converter can send out high energy invisible laser radiation. There is a risk for permanent damage to the eye. • Always use protective cover on all cables and connectors which are not connected. • Never look directly into a fibre cable or a connector. • Consider that a fibre can carry transmission in both directions. • During handling of laser cables or connections, ensure that the source is switched off. 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.

MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 1 1 Introduction Axell’s MBF-20 Multi-Band Fiber Optic system provides a cost-effective, scalable indoor solution for single or multi operator use. Signals are coupled off from a nearby base station or off-air repeater to the OMU and then distributed via fiber to one or several MBF-20 remote units. These MBF-20 remote units can be installed up to 2 km from the base station site, offering great flexibility when providing RF coverage in areas where off air transmission is not a preferable solution. A distributed antenna system can be used to distribute the signal throughout the area to be covered. A single F/O cable is used to connect the MBF-20 remote units to the OMU. Different colors (wavelengths) are used in order to combine the uplink of different MBF-20 remote units in a very cost effective way. The MBF-20 is supplied in two physical configurations: • Dual-band – consists of a single (Master) unit supporting two bands • Quad-band – consists of two cascaded units: Master and Expansion (Slave) units, where the Expansion unit can be assembled by the user onto an existing Master MBF-20 unit (see section 3.2). The MBF-20 is installed in conjunction with Axell Wireless Optical Management Unit (OMU II). The OMU II provides the head-end RF to optic conversion required to transport the services over fibre to the MBF-20 units. Up to 24 MBF-20 can be fed and managed from a single OMU II system. MBF-20 commissioning is designed for plug-and-play simplicity: just mount, connect antennas, power and fibre. The unit is automatically discovered and commissioned on the OMU II side via a Web GUI connection to the OMU II. Figure 1-1. Axell MBF-20 Dual-band (left) and Quad-band (right) Remotes

MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 27 Appendix B: Optic Fibre Cables Connections This product is equipped with Class 1 lasers, as per definition in EN 60825-1. Caution!!! Un-terminated optical receptacles may emit laser radiation. Do not stare into beam or view with optical instruments. Note: Angled connectors, APC, need to be used throughout the whole link between the unit and the remote. The angle needs to be 8 degrees. Also the ODF connections need to be APC type. The fibre must be monomode type. Connecting the Fibre Optic Cable 1. Select type of optic fibre (Recommended fibre cable is single mode 9/125). 2. Run the fibre through a corrugated sleeve. 3. Insert the cable via the Fibre input.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL 28 User Manual Doc No. 00068UM Rev. 2.4 © Axell Wireless Ltd 4. Connect the fibre to the Fibre Optic Converter inside the repeater. NOTE: Make sure the fibre is not bent too sharply inside the repeater as to avoid communication disruptions. 5. Place the fibre in the rubber seal. Note: The sleeve, together with the rubber seal, meets the protection standard IP65. 6. Adjust the fibre length inside the repeater and insert the seal into the fibre input interface.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 29 7. Attach the sleeve to the fibre optic inlet. Note: Clean the fibre connector before connecting it to the system. Optical reflections from a discontinuity such as a poor connector interface appear on an RF spectrum analyzer trace as stable variations in the noise floor amplitude that are periodic with RF frequency. If the reflection is bad enough, it could impact the system performance. The most common cause for a large discrete reflection is a dirty optical connector. A bit of dust or oil from a finger can easily interfere with, or block this light. Note: Perform the cleaning procedure as described in Appendix C: F/O Cleaning Procedure. Be sure to use the correct procedure for the given connector. When disconnected, cap the SC/APC connector to keep it clean and prevent scratching the tip of the ferrule.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL 30 User Manual Doc No. 00068UM Rev. 2.4 © Axell Wireless Ltd Appendix C: F/O Cleaning Procedure NOTE: The process is demonstrated on an OMU F/O module and is similar to all F/O equipment supplied by Axell. Tools: Tool Description Illustration Fibrescope connected to a PC running the appropriate viewing software. It is highly recommended that some form of fibre viewing equipment such as a Fibrescope is used to ensure that all fibre connections are clean before termination; failure to do so could result in poor system performance Lint-free swabs (box), Axell P/N 99-000127 Lint-free wipes (pack) Axell P/N 99-000125 Fujikura “One Click” cleaner, Axell P/N 98-900004. 99% isopropyl alcohol (can), Axell P/N 99-000126 Cletop type S Cassette Cleaner, Axell P/N 98-900068
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 31 The Cleaning Procedure: Dry Cleaning ATTENTION! Invisible laser radiation might be emitted from disconnected fibres or connectors. Do not stare into beams or view directly with optical instruments. Note the following: • Before cleaning the optical connectors on the OMU it is advisable to clean the connector of the mating cable being attached to the optical port. • An unclean optical connector is often the cause for reduced system performance. A bit of dust or oil from a finger can easily interfere with, or block light. Fortunately, it is very easy to clean the connector. Be sure to use the correct procedure for the given connector. When disconnected, cap the SC/APC connector to keep it clean and prevent scratching the tip of the ferrule. • Use a product specially designed for the purpose, such as the Cletop type S Cassette Cleaner. IMPORTANT: Always make sure there is a way of inspecting the connector after cleaning. Cleaning can actually leave the end-face in a worse condition, since alcohol residue is one of the most difficult contaminants to remove. 1. Begin by dry cleaning the F/O bulkhead connector (shown below is the Fujikura One-Click in use). 2. Remove the protective cap from the cleaning-head end of the “One Click” cleaner, lift the protective end-cap on the fibre connector and offer-up the end to the fibre connector 3. With the cleaning-head end fully engaged in the connector, push until an audible “click” is heard 4. Without fully withdrawing the cleaning head end push it in again twice more, each time until an audible “click” is heard.
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL 32 User Manual Doc No. 00068UM Rev. 2.4 © Axell Wireless Ltd 5. Withdraw the “One Click” cleaner and replace the protective end cap. 6. Inspect the fibre connector using a Fibrescope. On the PC monitor, verify that there is no contamination present on the connector end-face. 7. If the connector is dirty, clean it with a wet cleaning technique followed immediately by dry cleaning. This is to remove any remaining residue from the wet clean (the following steps demonstrate a wet cleaning technique).
MBF-20 AMERICAS REMOTE PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd User Manual Doc No. 00068UM Rev. 2.4 33 Wet Cleaning ATTENTION! Invisible laser radiation might be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. 1. Lightly moisten a new lint-free wipe with 99% isopropyl alcohol. (Step 1 below). Tip: Have a dry lint-free swab available for immediately drying after performing the wet-cleaning. 2. Lightly press and turn a clean lint-free swab in the moistened area of the wipe to moisten the swab. It is important that the swab is not too wet. (Step 2 below). 3. Insert the moistened lint-free swab into the bulkhead adapter. Lightly press and rotate several times in the same direction. (Step 3 below). Wet-Cleaning Technique 4. Immediately use a dry lint-free swab to clear any remaining alcohol residue. NOTE: Do not re-use any of the wipes and/or swabs. Dispose of them properly. 5. Follow steps 3 to 6 of Dry Cleaning above 6. Re-inspect the fibre using the Fibrescope. On the PC monitor, verify that there is no contamination present on the connector end-face. 7. If the fibre is still dirty, go back to step 1 (Wet Cleaning) and repeat the entire process. NOTE: The entire wet/dry cleaning cycle should only be used twice, if the fibre is still dirty after two cycles of wet/dry cleaning seek advice from the Axell Wireless Support Desk.
