調頻數位光纖直放站(FOR)是為了解決距離調頻電台較遠、地下有光纜網路的地方調頻廣播訊號較弱的問題而設計的。
系統由兩部分組成:主站(MU)和遠端單元(RU)。 MU透過施主天線捕捉FM廣播電台訊號,接收的訊號經過放大後進行數位處理並轉換為光訊號,然後透過光纜傳送到RU。 RU將光訊號重新轉換為RF FM無線電訊號,並將FM無線電訊號提供給網路覆蓋不足的區域。
The FM digital Fiber Optic Repeater (FOR) is designed to solve problems of weak FM radio signal in the place that is far away from the FM radio station and has fiber optic cable network underground.
The system consists of two parts: Master Unit(MU) and Remote Unit(RU). The MU captures the FM radio station signal via donor antenna, the received signal is amplified then digitally processed and converted into an optical signal, and then transmitted to RU via fiber optic cable. The RU will reconvert the optic signal into RF FM radio signal and provide the FM radio signal to the areas where network coverage is inadequate.
