1. 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.

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.

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
