1. a multi-plexing light accessing system, is characterized by,Possess:

  • Multiple Optical Network Terminal, there is the interface received and dispatched the signal of time division multiplexing mode and the signal of Packet Multiplexing mode and interface that is multiplexed and transmitting-receiving is carried out to the signal of above-mentioned time division multiplexing mode and the signal of above-mentioned Packet Multiplexing mode, and being connected with terminal respectively;

    Optical line terminal, there is the interface received and dispatched the signal of time division multiplexing mode and the signal of Packet Multiplexing mode and interface that is multiplexed and transmitting-receiving is carried out to the signal of above-mentioned time division multiplexing mode and the signal of above-mentioned Packet Multiplexing mode, and be connected with above-mentioned Optical Network Terminal via optical splitter and optical fiber, be connected on network;

    Between above-mentioned optical line terminal with above-mentioned Optical Network Terminal, use the periodic frame identical with above-mentioned time division multiplexing mode to communicate;

    For the signal being sent to above-mentioned network from above-mentioned Optical Network Terminal via above-mentioned optical line terminal,In above-mentioned Optical Network Terminal, use above-mentioned periodic frame to send the signal of above-mentioned time division multiplexing mode, when can not communicate with above-mentioned optical line terminal during the range finding measuring the distance between above-mentioned optical line terminal and above-mentioned Optical Network Terminal, be equivalent to the periodic quantity during above-mentioned range finding and temporarily keeping the signal of above-mentioned time division multiplexing mode, the signal of the time division multiplexing mode of the above-mentioned periodic quantity of maintenance is sent after above-mentioned range finding terminatesIn above-mentioned optical line terminal, by above-mentioned range finding take time in the signal of above-mentioned time division multiplexing mode that receives from above-mentioned Optical Network Terminal, temporarily keep in advance being equivalent to the periodic quantity during above-mentioned range finding, when can not communicate with above-mentioned Optical Network Terminal during above-mentioned range finding, the signal of the above-mentioned above-mentioned time division multiplexing mode temporarily kept in advance is sent to above-mentioned networkFor the signal being sent to above-mentioned terminal from above-mentioned optical line terminal via above-mentioned Optical Network Terminal,In above-mentioned optical line terminal, use above-mentioned periodic frame to send the signal of above-mentioned time division multiplexing mode, when can not communicate with above-mentioned Optical Network Terminal during finding range, be equivalent to the periodic quantity during above-mentioned range finding and temporarily keeping the signal of above-mentioned time division multiplexing mode, the signal of the time division multiplexing mode of the above-mentioned periodic quantity of maintenance is sent after range finding terminatesIn above-mentioned Optical Network Terminal, by above-mentioned range finding take time in the signal of above-mentioned time division multiplexing mode that receives from above-mentioned optical line terminal, temporarily keep in advance being equivalent to the periodic quantity during above-mentioned range finding, when can not communicate with above-mentioned optical line terminal during above-mentioned range finding, the signal of the above-mentioned above-mentioned time division multiplexing mode temporarily kept in advance is sent to above-mentioned terminal.
