NOKIA FLEXIHOPPER(RRI)

INTRODUCTION

• A Nokia Flexi Hopper network element consists of an indoor unit (IU) and an outdoor unit (OU).

• The units are connected together with a single coaxial cable, Flex bus.

• The Flex bus cable can be up to 300 m long.• One unit, all capacities; one platform, all frequencies• Nokia Flexi Hopper Microwave Radios are available for the 7, 8,

13, 15, 18, 23,26, and 38 GHz frequency bands. • The radio transmission capacity of all Nokia Flexi Hopper models

is 2 x 2, 4 x 2, 8 x 2, or 16 x 2 Mbit/s. • This can be selected using the node manager without any

hardware changes.

FXC RRI – Nokia Metro Site GSM BTS, Nokia Metro Hub, and NokiaNokia Ultra Site EDGE BTS indoor unit * FXC RRI is an indoor unit which can be installed in Nokia Metro Site GSM

Base Station, Nokia Metro Hub Transmission Node, or Nokia Ultra Site EDGE Base Station

* FXC RRI enables connection to two outdoor units, supports loop protection, and also provides grooming with 8 k bit/s granularity.

• Nokia Flexi Hopper Microwave Radios have many advanced features in addition to all the essential microwave radio features.

• Flex bus − single cable interconnections

INDOOR UNIT

• To install indoor unit inside the shelter Install the indoor unit in transmission rack.

Nokia flexi hopper outdoor unit

The Nokia Flexi Hopper OU is used together with an

antenna and an alignment unit.

INSTALLATION

• The outdoor unit can be installed on a roof, wall, or tower• The antenna with alignment unit can be installed on either

side of a pole. Normally, no loose parts are needed in the installation of the alignment unit and the outdoor unit.

• The outdoor unit and the antenna are fitted with guides which prevent installation in conflicting polarizations.

• FXC RRI is a plug-in indoor unit which can be installed in Nokia MetroSite GSM BTS, Nokia MetroHub, and Nokia UltraSite EDGE BTS.

CONNECTORS AND CABLING

• The indoor unit and the outdoor unit are connected via a single coaxial cable(Flex bus), which also feeds power to the outdoor unit.

• The outdoor unit has one coaxial connector for the Flex bus cable (TNC, 50 Ω) and one BNC connector for measurement of the AGC (automatic gain control) voltage.

• AGC voltage measurement is needed when aligning the antenna.

POWER SUPPLY

• The power is fed to the outdoor unit from the indoor unit via the Flex bus cable(55 VDC nominal voltage). No separate power supply is needed.

• The power consumption of a Nokia Flexi Hopper outdoor unit is less than 25 W.

• The actual power consumption depends on the site equipment and the power losses caused by the equipment.

Power supply

• The power supply systems are shown in Fig. 2-9 (1/3) to (3/3). The DCD CONV module in the MODEM module produces regulated +3.6 V DC from −48 V *1 DC input for the component modules on the IDU. Also,this module supplies a −48 V DC to the ODU.

• The DC V to the ODU is supplied through the coaxial cable which is also used for the IF and other signals. The PS circuit on the ODU produces +7/+8/+9/−7/−8/−9 * and −15 V DC for the component modules from the −48V DC supplied from the IDU.

• The −48 V power supply system for the PASOLINK NEO must be separated from existing power supply system. The PASOLINK, PASOLINK+, PASOLINK Mx, etc. That uses −43 V DC and floating polarities.
