Fiber Link 208

 光纖中繼器（FOR）旨在解決遠離基站收發站（BTS）且地下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：主單元和遠端單元。主單元通過靠近 BTS 的直接耦合器捕獲 BTS 信號，然後將其轉換為光信號，並通過光纖電纜將放大後的信後將其轉換為光信號，並通過光纖電纜將放大後的信 號傳輸到遠端單元。遠端單元將光信號重新轉 換為射頻信號，並將信號提供給網絡覆蓋不足 的區域。並且移動信號也被放大並通過相反的 方向重新傳輸到 BTS。

l   Tx/Rx 控制和報警信息可以通過一根光纖傳輸 

l   採用 WDM 模組實現遠距離傳輸 

l   穩定且提升的信號傳輸質量 

l   一個主單元最多可支援 8 個遠端單元，最大限度地利用光纜 

l  RJ45 端口提供連接筆記本電腦的本地監控或基於 IP 的 NMS（網絡管理系統），可以遠端監控中繼器的工作狀態，並通過以太網/局域網將運行參數下載到中繼器

擴大信號覆蓋範圍或填補信號弱或不可用的信號盲區。 戶外： 機場、旅遊區、高爾夫球場、隧道、工廠、礦區、村莊…… 室內： 酒店、展覽中心、地下室、商場、辦公室、停車場……

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.

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

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

l  Adopting WDM module to realize long-distance transmission 

l   Stable and improved signal transmission quality 

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

l   RJ45 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 Ethernet/LAN
