空中耦合光纖直放站(FOR)是為解決遠離基站收發台(BTS)、地下有光纜網絡的地方移動信號弱的問題而設計的。
該系統由兩部分組成:主單元(MU)和遠程單元(RU)。 MU 通過空中耦合將 BTS/Repeater 信號捕獲到 BTS,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 RU。 RU 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傳到BTS。
The Air Coupling 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 (MU) and Remote Unit (RU). The MU captures the BTS/Repeater signal via Air Coupling to the 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.
