Patent ID: 8488966

Claim:
An optical access network (OAN) system, comprising: a remote radio unit (RRU); an optical network device; an optical distribution network (ODN); an optical line terminal (OLT) device, wherein; the RRU is configured to receive a wireless service data, convert the wireless service data into a first frequency signal, and send the first frequency signal to the optical network device; the optical network device is configured to receive the first frequency signal from the RRU, convert the first frequency signal into a fiber transmission signal, and send the fiber transmission signal to the ODN; the ODN is configured to transmit the fiber transmission signal sent by the optical network device to the OLT device; and the OLT device is configured to receive the fiber transmission signal transmitted by the ODN, and convert the fiber transmission signal into a signal of another standard protocol which is sent to an IP edge node through a convergence network; wherein the optical network device comprises an optical network unit (ONU) and is specifically configured to: receive the first frequency signal from the RRU, adapt a rate of the wireless service data from the RRU to a GPON transmission rate, perform frame format conversion on the first frequency signal to obtain a first adaptation signal, and convert the first adaptation signal into the fiber transmission signal according to an optical transmission protocol.
