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 signal transmission processing method and apparatus and a distributed base station are provided according to the embodiments of the present invention. The distributed base station includes a Base Band Unit (BBU) and a Remote Radio Unit (RRU). A transmitting end connected to one of the BBU and the RRU receives at least one of interface signals from the one connected thereto, performs optical transport network (OTN) electrical layer multiplexing to obtain OTN signal frames and transmit optical signals including the OTN frames to a receiving end connected to the other of the BBU and the RRU. The receiving end performs frame processing for the OTN frames received from the transmitting end to obtain the interface signals, and transmit the interface signals to the other connected thereto.

摘要： A method for protecting WDM transmission. On the first transmission direction, the first node implements service transmission to the second node by selecting one from the two transmission paths protected by each other, the second node implements two-path reception based on the two transmission paths; on the second transmission direction contrary to the first transmission direction, the second node implements two-path service sending via the two transmission paths protected by each other, the first node implements reception by selecting one from the two transmission paths. A system for implementing the WDM transmission protection and an apparatus thereof.
