Introduction 1.1 Fiber Fed Repeater The JF43 FFR provides a cost effective solution for cell extension coverage and increased call quality in shadow areas. It is a RF signal transport system that provides long range RF coverage where it is impractical to install a BTS. The JF43 FFR is designed to be strategically placed to overcome difficult zoning issues by allowing the base stations to remain at a central location while placing antennas at remote locations. RF signals can be transported to remote locations to expand coverage into areas not receiving service or to extend coverage into difficult to reach areas such as canyons, tunnels and underground parking lots and roadways. The JF43 FFR provides a high-tech, highly-efficient service system which enables high quality communication at low cost, due to the system’s utilization of one optical fiber core between the DHU and RU supporting full duplex transmission of signals for both the DL and UL.

JUNI JF43-E1900/CFN03 CDMA FIBER FED REPEATER OPERATIONS MANUAL Version 1.17 ⓒ Juni America Inc. Page 9 of 88 1.3 Advantages There are many advantages to deploying a FFR. • Supports adjacent block interference protection which allows just one model of the FFR to cover the entire PCS frequency range. The FFR is settable to allow a combination of 85 different frequencies to be serviced. This advanced filtering personality prevents interference from adjacent frequency blocks. • Allows for versatile deployment architectures. Extra optical transceiver modules can be added to the DHU to increase service coverage. A flexible RF splitter unit can also be implemented to combine multiple RF ports supported by newer BTS. • The slim and sleek appearance of the RU allows it to be installed and deployed in difficult zoning areas. • Its water and moisture resistant NEMA 4X structure make it reliable and durable. • The FFR system is monitored and controlled from a central remote location by making use of a CDMA wireless modem via the SNMP protocol. • Operation and maintenance and repair is simple. The system provides alarms and information on the repeater gain settings, output level control, HPA on/off, internal temperature monitoring and problems concerning the optic module. The system is designed to operate with a comprehensive network management system. • The system uses only one optical fiber core for transmission and reception of signals. To achieve this, WDM is implemented which enables multiple wave-lengths (FWD: 1550nm, REV: 1510nm) to be simultaneously transmitted and received through the one optical fiber core.

Page 11 of 88 1.5 General Safety Precautions This equipment contains components that emit laser radiation which can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. An optical power meter or reflectometer should be used to verify active fibers. Place a protective cap or lid immediately over any radiating transceiver or optical fiber connector to avoid potential damage caused by radiation exposure. This practice also prevents dirt particles entering the openings. The optical fiber emits radiation. Do not look directly into the ends of an optical fiber. This may result in exposure to radiation. Do not assume laser power is turned off or the fiber is disconnected at the other end. Wet locations and conditions will increase the risk of electrical shock when installing or using electrical powered equipment. To prevent electrical shock, never install or use electrical equipment in wet locations or during lightning storms. The DHU is powered by 50-88VAC. To prevent electrical shock when installing or maintaining the DHU, disconnect the wiring at the power source before working with un-insulated wires or terminals. The RU is powered by 115VAC. To prevent electrical shock when installing or maintaining the RU, disconnect the wiring at the power source before working with un-insulated wires or terminals. Always consider and allow sufficient fiber length to permit routing or patch

Page 36 of 88 [Figure 3.17] Connection to perform optic cable loss test Check optic cable loss by using an optic power meter or reflectometer 1. With the DHU on, connect the power meter to the optic module of the RU and measure the Forward (1550nm) output level. If the optic input level exceeds +6dBm, check the DHU optic module. 2. If the optic loss is larger than –6dBo (on the basis of 1510nm, optic loss = donor output optic power – remote input optic power) through calculating with measured optic power and if the optic cable length between the DHU and RU is less than 15 miles, check if there is a fault in the PD (Photo Diode) or check the optic cable. 3. If a PD fault has occurred inspect the optic input level and check the optic line. Clean the optic connector and if a fault is still existent, send the repeater back to Juni for repair. * Reference a. Optic cable loss is 0.25dB/km at 1510nm, and connection loss is 0.4dB/connector. The total optic deviation of connector is about 1to2dB. (0.4dB ×2 (connector) = about 1dB) b. At the time of delivery, the Gain is set to be about 38dB (Tx), 20dB (Rx) as a default on the basis of optic cable length being 15 miles. 3.5.14 Setup Procedure for DL/UL Path Gain This section provides test procedures for the uplink and downlink required to be undertaken in order to set up the JF-43 for optimal service. 3.5.14.1 Setup for UL Gain 1.

System Maintenance This section explains the JF43 FFR system fault detection and alarm reporting system, and provides a method for determining troubleshooting faults. Maintenance also includes diagnosing and correcting service problems as they occur. When an alarm is reported, it will be necessary to follow a systematic troubleshooting procedure to determine the problem. Once the problem has been isolated, the appropriate corrective measures must be taken to restore service. The only internal components that can be replaced are the cooling fans which are mounted in the DHU and RU. All other failed internal components will require Juni engineers to replace and test the units. 5.1 Periodic Maintenance The JF43 FFR requires minimal regular maintenance to insure continuous and optimal operation and performance. However, it is advised that the DHU and RU are checked often. Components that require regular replacement, cleaning, or testing include the DHU and RU fans and backup battery. The NEMA 4X enclosure ensures that the JF43 FFR can withstand all environmental influences. The following two procedures can also be followed when a fan fails and needs to be replaced. 5.1.1 Donor Unit Fan Maintenance 1. The fan is located above the MCU and is labeled ‘Fan Control Unit’. 2. Unplug the 24V power cable feeding the Fan Control Unit. 3. Unscrew the two multi-turn fasteners on each side of the compartment. 4. Pull out the Fan Control Unit completely from its position. 5. One fan is used to cool the DHU which will require regular maintenance by
JUNI JF43-E1900/CFN03 CDMA FIBER FED REPEATER OPERATIONS MANUAL Version 1.17 ⓒ Juni America Inc. Page 69 of 88 cleaning and/or dusting. 6. Once maintenance is complete, return the Fan Control Unit back into its space and tighten the multi-turn fasteners. 7. Plug the power cable back into the Fan Control Unit. 5.1.2 Remote Unit Fan Maintenance 1. The fan compartment is located at the top of the RU. 2. Turn off the fan at the fan controller. 3. To perform maintenance on the fan for the RU, turn the eye bolts at the top of the RU a quarter turn to unlock the fan compartment and then slide it out of the RU. The fan compartment has a draw stud which latches onto a predefined hole to prevent the fan compartment from falling out. 4. Pull out the fan compartment firmly to release the stud from its hole. Do not pull on it too hard as a 24V power cable is directly connected to the fan compartment. 5. There are two fans in the compartment which is required to be cleaned and checked regularly to ensure proper operation of the fan and allow the fan to perform its duty in cooling the RU. 6. At the completion of the maintenance, return the fan compartment by sliding it back into its designated placement. 5.2 Fault Detection and Alarm Reporting The JF43 FFR on board embedded software detects various unit and system faults which generate either a Major or Minor alarm. A major alarm indicates that the repeater has failed in a way that directly affects RF transport performance. When a major alarm occurs, all RF functions are affected and will cause the system to be out of service. A minor alarm means that the system performance is not affected, or in some cases, that the performance may no longer be optical. When a minor alarm occurs, RF functions continue and the system remains in service.
JUNI JF43-E1900/CFN03 CDMA FIBER FED REPEATER OPERATIONS MANUAL Version 1.17 ⓒ Juni America Inc. Page 70 of 88 The following means are used to report major and minor alarms. • DHU, RU LED’s • LMT software Graphical User Interface (GUI) The DHU and RU front panel LED indicators show status and alarm information by displaying various colors; green, red and off.
