3G&Lte Quad Band Fiber Optic Repeater 700MHz 850 MHz 900MHz 2100MHz

Specifications of 3G&LTE Quad Band Fiber Optic Repeater
The Fiber Optic Repeater (FOR) 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: Donor Unit and Remote Unit. The Donor unit captures the BTS signal via direct coupler closed 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 network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
Features
Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
Omni-directional antenna can be adopted to expand more coverage
Tx/Rx control and alarm messages can be transmitted via one fiber optic cable
Adopting WDM module to realize long-distance transmission
Stable and improved signal transmission quality
One Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cable
USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeaterApplications
To expand signal coverage or fill signal blind area where signal is weak or unavailable.Outdoor:Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …Indoor:Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …Application Diagram
