MRU Power Specifications I nt rod uct i on CMA -XXX- A E N Draft P a ge 1 0 1.3 System Architecture Figure 1-2 illustrates the MRU system architecture. In the downlink, at the headend, the BTS/BDA signal is conditioned at the headend unit (e.g. integrated headend unit IHU)), by the service specific radio interface modules (RIM), ensuring a constant RF level. The conditioned signals are then converted by the optical interface modules (OIM) to an optical signal for transporting over single-mode fiber to the MRU at the remote location. In the uplink, the process is reversed. All mobile services are combined and distributed through a single antenna port over the broadband antenna infrastructure installed at the remote locations.

MRU LED Descriptions MRU I nt e rf aces CMA -XXX- A E N Draft P a ge 1 5 3 Installation Guidelines This chapter provides installation guidelines for the Corning ONE™ wireless platform MRU. The following installation rules are based on the assumption that the site survey and installation planning (including power requirements) have been completed. This includes planning the distribution of antennas to provide the required coverage, as well as planning the layout of the devices and cables in the telecom closet or shaft. 3.1 • • • Site Considerations The distance between the MRU service antenna and the coverage area should correspond to LOS (Line of Sight) requirements for maximum coverage area The maximum fiber path loss is 5 dB The system delay of the optical system must be taken into consideration when there are neighboring BTS sites overlapping in coverage 3.2 Safety Guidelines Before installing the equipment review the following safety information: • • • • • • Follow all local safety regulations when installing the equipment. Only qualified personnel are authorized to install and maintain the repeater. Ground specified equipment with the provided grounding bolt Do not use the grounding bolt to connect external devices. Follow electro-static discharge (ESD) precautions. Use low loss cables to connect the antennas 3.3 • • • • • • • • • • • • Installation Requirements Mounting surface shall be capable of supporting the weight of the equipment. In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize interference from electromagnetic sources such as large electrical equipment. Working space available for installation and maintenance for each mounting arrangement. Ensure unrestricted airflow. Ensure grounding connector is within reach of the ground wire. Ensure a power source is within reach of the power cord and the power source has sufficient capacity. Where appropriate, ensure unused RF connectors are terminated. Do not locate the equipment near large transformers or motors that may cause electromagnetic interference. Reduce signal loss in feeder cable by minimizing the length and number of RF connections. Ensure the equipment is operated within the stated environment (refer to Appendix A: Specifications or unit datasheet). Where appropriate, confirm available of suitably terminated grade of RF and optical fiber. Observe handling of all cables to prevent damage.

Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation. • • • • • • Only trained and qualified personnel should be allowed to install or replace this equipment. The equipment has been designed to operate at the temperature range as stated in the product specifications. Verify that ambient temperature of the environment does not exceed the maximum MRU operating temperature of 65°C (149° F) IMPORTANT! If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient. Therefore, ensure that the installation environment complies with the maximum MRU operating temperature. To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack from the bottom to the top. Ensure that adequate airflow and ventilation within the rack and around the installed components so that the safety of the equipment is not compromised. It is recommended to allow for at least about 2 cm of airspace between devices in the rack. Verify that the equipment is grounded as required – especially in installations using supply connections other than direct connections to the branch circuit (e.g. use of power strips). 3.3.1.2 • • Rack Installation Guidelines To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack from the bottom to the top. Verify that the rack height can support the unit to be installed (MRU rack height = 6U), where you may also want to consider future installations. 3.4 Power Requirements 3.4.1 Power Safety Instructions SAFETY WARNINGS! When installing or selecting the power supplies: • • • • • For AC models – only use the provided AC power cable (straight, U.S 10 A ,UL, L = 1.8-2.5 m ,black,110 V ) to connect the power supply to the MRU. Be sure to disconnect all power sources before servicing. Calculate the required power according to the requirements of the specific installation and then determine the configuration of the power supplies. The required DC cables will then be determined by the selected PS configuration. Use only UL approved power supplies Install external over-current protective devices for the system according to the power specifications described in 1.2.3. 3.4.2 Types of Power Supplies Corning supplies various power supplies that can be installed in a rack or mounted on a wall, depending on your configuration. 3.4.3 Circuit Breakers Calculate the required fuse protection while referring to power specifications described in Appendix A: Specifications. When installing fuse protections for the system, make sure to take into account other Corning system elements that may require external fuse protection as well.

The building code requires that all cabling be installed above ceiling level (where applicable). The length of cable from the risers to each antenna must be concealed above the ceiling. The cable must be properly supported and maintained straight using velcro cable ties, cable trays and clamps or hangers every 10 feet (where practical above ceiling level). Where this is not practical, the following should be observed: The minimum bending radius of the supplied ½” coax cable should be 7”. Cable that is kinked or has a bending radius smaller than 7” must be replaced. Cable runs that span less than two floors should be secured to suitably located mechanical structures. The cables should be supported only from the building structure. All cables shall be weather-resistant type. Cable length - determined by the system installation plan. When calculating the cable length, take into account excess cable slack so as not to limit the insertion paths. 3.5.2 • • • • • • RF Rules Use coax RG-223, 50 ohm, male-to-male N-type to QMA for RF connections from the RIMs to the BTS/RBS and to the MRU. When using the Corning remote unit in an environment in which other indoor coverage systems are installed, it is recommended (where possible) that the antennas are placed at least two meters apart When bending coax cables, verify that the bending radius does not exceed the coax specifications. Use wideband antennas supporting a range of 300 MHz to 3 GHz Terminate all unused MRU RF ports with a 50 ohm load Make sure that the VSWR measured at the coax cable meets the product specification The VSWR must be measured prior to terminating the MRU RF ports in the remote communication rooms. 3.5.3 Coax Cable Lengths and Losses Use coax RG-223, 50 ohm, for RF connections between MRU unit and DAS antennas. Note: The required distance between the antennas (installed in the ceiling) depends on the infrastructure and calculated path-loss. For example, if there is free space-loss between the antennas, a minimum distance of 100 ft is required; if there are partitions (loss) between the antennas, a distance of less than 100 ft between them is allowed.

VSWR/Return Loss:12 dB • Max. Insertion Loss (dB): 0.2 • • Number of antennas that can be connected (with cables/splitters) – it is not recommended to connect more than one antenna per connector since 1:1 connectivity is reduced with each split. Types of couplers/splitters – depends on number of splits (not recommended) 3.6.2 • • • • General Installation Guidelines The MRU should be installed at a convenient location, free of metallic obstruction (can also be installed in plenum spaces). Install the MRU at the designated height and tune it roughly toward the service coverage area. Installation of this antenna must provide a minimum separation distance of 100 cm from any personnel within the area. Cable and jumper loss is at least 2 dB. I nst al l ati o n G u id e li n es CMA - XXX- A E N Draft P a ge 2 0 3.7 Fiber Optic Requirements 3.7.1 Authorized Optic Cables The following specified optic cables are authorized for use with the MRU product: • • • • Composite plenum tether assemblies Fiber: LC APC, 2 – 24 fibers Cu: 16 AWG, 14 AWG, 12 AWG; 2 – 12 Conductors Armored, non-armored 3.7.2 • • • • • • • • • • • Fiber Optic Rules Use only LC APC connectors UniCam connectors can be used for field termination Use only fusion splice for connecting two fibers Use minimum splicing/connectors to achieve minimum losses on the fibers (< 0.5 dB) Use precaution while installing, bending, or connecting fiber optic cables: • Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable specification sheet for the cable you are installing. • Do not bend cable more sharply than the minimum recommended bend radius. • Do not apply more pulling force to the cable than specified. • Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics of the cable. The cable may have to be replaced. Use an optical power meter and light source for checking the fiber optic cables Make sure the environment is clean while connecting/splicing fiber optic cables All fiber optic connectors should be cleaned prior to connecting to the system Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are terminated. Pay special attention while connecting the LC APC connectors – ensure that you hear a “click”, indicating a secure connection Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can damage your eyes. 3.8 Grounding Requirement Verify that the equipment has been well grounded (refer to the grounding lug on the bottom front panel of the MRU chassis. This includes antennas and all cables connected to the system. Ensure lightning protection for the antennas is properly grounded. See sections 4.2.3 for MRU grounding connection. 3.9 Manual Handling During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation personnel and the equipment.
