摘要： A central office optical line terminal (S-OLT) and a local optical line terminal (L-OLT) are connected to through a transmission link form a transmission network. The S-OLT sends service data sent by a service network to the L-OLT through a transmission channel, receives the service data sent by the L-OLT from the transmission channel, and sends the service data to the service network. The L-OLT receives the service data sent by the S-OLT from the transmission channel and sends the service data to an optical network unit (ONU), and sends the service data sent by the ONU to the S-OLT through the transmission channel. Thus, the service data of the L-OLT is sent to the service network through the S-OLT, thereby solving a problem in the existing PON that the service data requires another transmission of the transmission network to reach the service network.
