FIBER LINK 104/404

光纖直放站（FOR）旨在解決遠離基站收發器（BTS）且地下具有光纜網絡的地方移動信號弱的問題。

該系統由兩部分組成：主單元和遠程單元。主單元通過與BTS閉合的直接耦合器捕獲BTS信號，然後將其轉換為光信號，並通過光纜將放大後的信號傳輸到遠程單元。遠程單元會將光信號轉換為RF信號，並將信號提供給網絡覆蓋範圍不足的區域。並且移動信號也被放大並經由相反的方向重發到BTS。 

l   防護等級為IP65的鋁合金外殼具有很高的防塵，防水和防腐蝕性能

l   可以通過一根光纜傳輸Tx / Rx控制和警報消息

l   穩定且改善的信號傳輸質量

l   一個主單元最多可支持8個遠程單元，以最大程度地利用光纜

l   USB / RJ45端口提供了到筆記本電腦的鏈接以進行本地監控，或者提供了內置的無線調製解調器或4G路由器以與NMS（網絡管理系統）進行通信，後者可以遠程監控中繼器的工作狀態並通過以下方式將工作參數下載到中繼器帶有APP的筆記本或手機。

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: Master Unit and Remote Unit. The Master 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. 

n  Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding

n  Tx/Rx control and alarm messages can be transmitted via one fiber optic cable

n  Stable and improved signal transmission quality

n  One Master Unit can support up to 8 Remote Units to maximize utilization of fiber optic cable

n  USB/RJ45 port provides a link to a notebook for local supervision or to the built-in wireless modem or 4G Router to communicate with the NMS (Network Management System) that can remotely supervise repeater’s working status and download operational parameters to the repeater by a notebook or mobile phone with APP.
