    • A remote access unit (RAU) apparatus, coupled to a central station (CS) of an RoF network through at least one optical fiber, and which RAU apparatus includes at least one antenna, includes: first and second antenna ports coupled to the at least one antenna; first and second optical fiber ports coupled to the at least one optical fiber; a first coupler for decoupling a first downstream signal of a first duplexing method and a second downstream signal of a second duplexing method, which are input through the first optical fiber port; a circulator for outputting the first downstream signal input from the first coupler to the first antenna port and outputting a first upstream signal of the first duplexing method input from the first antenna port to the second optical fiber port; and a second coupler for outputting the second downstream signal input from the first coupler to the second antenna port and outputting a second upstream signal of the second duplexing method input from the second antenna port to the second optical fiber port.
    • 一种远程接入单元(RAU)装置,其通过至少一个光纤耦合到RoF网络的中心站(CS),并且所述RAU设备包括至少一个天线,包括:耦合到所述至少一个天线的第一和第二天线端口 一个天线 耦合到所述至少一个光纤的第一和第二光纤端口; 用于去耦第一双工方法的第一下行信号和通过第一光纤端口输入的第二双工方法的第二下行信号的第一耦合器; 输出从第一耦合器输入的第一下行信号到第一天线端口的循环器,并输出从第一天线端口输入到第二光纤端口的第一双工方式的第一上行信号; 以及第二耦合器,用于将从第一耦合器输入的第二下行信号输出到第二天线端口,并输出从第二天线端口输入到第二光纤端口的第二双工方法的第二上行信号。
