Description

technical field [0001] The present invention belongs to the technical field of Internet communication, and in particular relates to the construction of a hardware platform for optical fiber access technology, in particular to an Optical Line Terminal (OLT) and an optical network in a Gigabit-Capable Passive Optical Network (GPON) The node (OpticalNetworkUnit, ONU) is built based on the hardware platform of FPGA (Field-ProgrammableGateArray). Background technique [0002] With the rapid development of the Internet, Internet services continue to increase, and users' demand for Internet bandwidth is also increasing. At present, the backbone core network around the world has basically realized fiber optics. Compared with the core network, the access network has become the bottleneck in the current network development process due to factors such as cost and media. [0003] At present, the access network is mainly broadband access, and the traditional access methods are mainly di...
