A system, a method, and a device for passive optical network (PON) data transmission are provided. A central office optical line terminal (S-OLT) (202, 601) and a local optical line terminal (L-OLT) (203, 610, 630) are connected to through a transmission link form a transmission network. The S-OLT (202, 601) sends service data sent by a service network to the L-OLT (203, 610, 630) through a transmission channel, receives the service data sent by the L-OLT (203, 610, 630) from the transmission channel, and sends the service data to the service network. The L-OLT (203, 610, 630) receives the service data sent by the S-OLT (202, 601) from the transmission channel and sends the service data to an optical network unit (ONU) (201), and sends the service data sent by the ONU (201) to the S-OLT (202, 601) 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. |
