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.

摘要： A method, device and system for implementing a long reach passive optical network (LR-PON) are provided, which solve the problem that the cost for establishing an LR-PON system is high. The method includes: receiving an uplink burst packet transmitted by an optical network unit (ONU) in a burst manner (101) , converting a burst optical signal of the uplink burst packet into a continuous optical signal, and transmitting the continuous optical signal to a receiving device (105). The present invention is applicable to an LR-PON.
