Abstract:
Disclosed in the present invention are a method and apparatus for processing downlink frame synchronization in a Gigabit-capable passive optical network (GPON) system, wherein the method comprises: carrying out forward error correction (FEC) encoding on data in a synchronization domain of a downlink frame of the GPON system, wherein the synchronization domain includes a physical synchronization (Psync) domain and an identifier (Ident) domain; filling the FEC encoded data into an FEC check domain provided in the downlink frame; and sending the downlink frame. By virtue of the present invention, the effect of improving the reliability of GPON downlink frame synchronization is achieved.
