<p>An optical access network system is provided. The system includes: RRU (1), for transmitting and receiving radio signal, and realizing the conversion between the radio signal and the first intermediate/radio frequency signal; ONU/ONT (2), for receiving or transmitting radio signal, and realizing the conversion between the radio signal and the first intermediate/radio frequency signal, and the conversion between the first intermediate/radio frequency signal and the fiber transmission signal; ODN (3) connected with said OUN/ONT (2), for transmitting said fiber transmission signal; OLT device (4), for receiving or transmitting said fiber transmission signal, and realizing the conversion between said fiber transmission signal and the second intermediate/radio frequency signal, and the conversion between said second intermediate/radio frequency signal and base band signal, and the conversion between said base band signal and other standard protocol signal. The present invention also provides an ONU/ONT (2), an OLT device (4) and a data transmission method of the optical access network.</p> |
