产品简介

详细介绍

TETRA Repeater TR-400

Product Description

The Fiber Optic Repeater is designed to solve problems of weak terminal signal in the place that is far away from the Base Transceiver Station (BTS) and has fiber optic cable network underground.
The system consists of two parts: Master Unit and Remote Unit. The Master unit captures the BTS signal via Donor antenna to BTS, then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cable. The Remote unit will reconvert the optic signal into RF signal and provide the signal to the areas where signal coverage is inadequate. And the terminal signal is also amplified and retransmitted to the BTS via the opposite direction.

Features

Ø Remote Unit - Aluminum-alloy casing with IP55 protection has high resistance to dust, water and corroding
Ø TX/RX control and alarm messages can be transmitted via one fiber optic cable
Ø Adopting WDM module to realize long-distance transmission
Ø Modules structure, Full-duplex & dual-port design, and built-in power supply, easy for maintenance and installation
Ø One Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cable

Applications

To expａnd signal coverage or fill signal blind area where FM signal is weak or unavailable.
Ø Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages
Ø Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots
