Quad Band Fiber Active Das - Multi Distributed Antenna System

With the development of mobile communication technology, more and more new communication technologies (such as 5G) are being used nowadays. As a result, telecom operators have to run multiple systems simultaneously and provide multi-system services (2G/3G/4G/5G) in one coverage area, resulting in the difficulty of installation and transmission of equipments. For the above mentioned reasons, Multi-Band Fiber DAS is designed to solve the problems of weak mobile signal in the place that is far away from the BTS and has fiber optic cable network underground. The system consists of two parts: Master Unit(MU) and Remote Unit(RU). The MU captures the BTS signal via direct coupler close to BTS, then converts it into optic signal and transmits the amplified signal to the RU via fiber optic cable. The RU will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction. Feature: 1. Aluminum-Alloy casing with IP65 protection for high resistance to dust, water and corrosion. 2. Supports 2G/3G/4G/5G, supports multi-bands and multi-operators 3. Adopting WDM module to realize long-distance transmission. 4. Tx/Rx control and alarm messages to be transmitted via one fiber optic cable. 5. One MU supporting up to 2 RUs to maximize utilization of fiber optic cable. 6. USB port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise Repeater's working status and download operational parameters to the Repeater Via Etherne To expand signal coverage or fill signal blind area where signal is weak or unavailable.
