空中接口光纖直放站(FOR)是為解決遠離基站收發台(BTS)且地下有光纜網的地方移動信號弱的問題而設計的。
該系統由兩部分組成:主控單元(MU)和遠程單元(RU)。 MU通過空中接口捕獲BTS信號,將其轉換為光信號,放大後的信號通過光纜傳輸給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方向重傳到BTS。

The Air Interface 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 signal via air interface, 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.
