TETRA光纤直放站远端机 TR-400 CE
Product Description
The TETRA Fiber Optic Repeater is designed to solve problems of weak mobile 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 of TETRA Repeater 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.
Features
Ø Remote Unit - Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
Ø Adopting digital optical module technology for low transmission loss and long distance.
Ø Modules structure, dual-port design, and built-in power supply, easy for maintenance and installation;
Ø Support optical loop and optical side functions, increase device stability, and reduce optical path failure issues.
Ø One Donor Unit can support up to 24 Remote Units to maximize utilization of fiber optic cable
Applications
To expand signal coverage or fill signal blind area where TETRA 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
