1. An optical network for bidirectional communication, comprising:

  • a base station for generating downlink optical signals and detecting uplink optical signals; and

    a remote antenna unit for transmitting the downlink optical signals, converting uplink radio signals, into the uplink optical signals to output the uplink optical signals to the base station;

    wherein the remote antenna comprises;

    an optical detector for converting the downlink optical signals into downlink radio signals;

    an antenna for transmitting the downlink radio signals to outside thereof and receiving the uplink radio signals;

    a semiconductor optical amplifier for converting the uplink radio signals into the uplink optical signals to output the uplink optical signals to the base station; and

    a circulating device having a plurality of ports, each of which is connected to the antenna, the optical detector, and the semiconductor optical amplifier, respectively.
