Abstract

The embodiment of the invention provides a data sending method and device, a data receiving method and device, an OLT (Optical Line Terminal) and an ONU (Optical Network Unit). The data sending methodcomprises the steps that the ONU fragments to-be-sent data which needs to be sent on a plurality of channels bound with the ONU, thereby acquiring a plurality of pieces of fragmented data; the ONU distributes the plurality of pieces of fragmented data to the plurality of channels according to uplink bandwidths allocated to the plurality of channels by the OLT, wherein the uplink bandwidths are the bandwidths allocated to the plurality of channels by the OLT according to the total data quantity of the to-be-sent data of the ONU; and the ONU sends the plurality of pieces of fragmented data to the OLT through the plurality of channels.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data sending and receiving method and device, an Optical Line Terminal (abbreviated as OLT), and an Optical Network Unit (abbreviated as ONU). Background technique [0002] With the development of network technology, the network can be used to transmit a large amount of voice, data, video and other services, so the requirements for bandwidth continue to increase. Passive Optical Network (PON) was born under this demand . [0003] The topology of the PON system is as follows figure 1 As shown, the PON system usually consists of an optical line terminal (OLT) at the office side, an optical network unit (ONU) at the user side, and an optical distribution network (ODN for short), and usually adopts a point-to-multipoint network structure. ODN is composed of passive optical components such as single-mode optical fibers, optical splitters, and optical connectors, and provides opti...
