摘要
Embodiments of the present invention disclose a method and a system for realizing PON reach extension, and a relay apparatus for realizing this method. The method includes: extracting an overhead in an upstream data stream that is sent by an ONU to an OLT, obtaining a payload in the upstream data stream through de-mapping, and storing it into a buffer; extracting bandwidth authorization information in an downstream data stream that is sent by the OLT to the ONU; and reorganizing a stored payload according to the bandwidth authorization information and inserting a corresponding overhead to generate a new upstream data stream and send it to the OLT.
