Product Description

Tetra 420Mhz fiber optic signal repeater

This repeater is mainly applicable to such case:
Underground fiber optic cable network already exists beneath the area to be covered;there is huge obstructive terrain between the BTS and the area to be covered;the distance between the BTS and the area to be covered is 20 km around.

Introduction

The Fiber Optic Repeater system consists of two parts: Donor Unit and Remote Unit.One Master can work together with 1 to 8 Slaves. The Master transfers the BTS signal into optical signal and transmits the optical signal to the Slaves. The Slaves transfer the optical signal into RF signal, amplify the RF signal and cover the target areas. The application of Fiber Optical repeaters will effectively eliminate the signal blind areas, enhance the network quality, improve the image of cellular operators and bring them more profit.

Technical features

1.Aluminum alloy enclosure for excellent heat dissipation,waterproof design for all-weather installation;
2.Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
3.Modules structure,full-duplex & dual-port design, and built-in power supply,easy for maintenance and installation;
4.High linearity PA; high system gain;
5.ALC and AGC to ensure stable operation;
6.Max transmission distance between Donor Unit and Remote Unit is 20KM;
7.Press-key , Local PC GUI operation and Optional Remote Modem control.
8.Can support up to 8 pcs RU with 1 pcs MU
