Description
Technical Field
The present disclosure relates to communication technologies, and in particular, to a method, system, and device for implementing geographical display of an optical network unit.
Background
The EPON system mainly comprises an OLT (Optical Line Terminal ), an ODN (Optical Distribution Network, optical distribution network) and an ONU (Optical Network Unit ).
The OLT is typically placed in a Central Office (Central Office), and is a core device that provides an interface between an EPON system and a service provider's core data/video/telephony network.
The ODN is composed of an optical fiber and one or more passive optical devices such as POS (Passive Optical Splitter ) and provides an optical signal transmission channel between the OLT and the ONU. The POS may couple upstream data onto one fiber and distribute downstream data to individual ONUs.
The ONU is used for connecting network devices (such as a PC, a set-top box, and an exchange) on the user side, and is usually placed in a user's home, corridor, or roadside, and is mainly responsible for forwarding uplink data (packets sent by the ONU to the OLT) on the user side and selectively receiving downlink broadcast data (packets sent by the OLT to the ONU) forwarded from the OLT side.
The OLT is connected to the NMS (Network Management System ) via ethernet for graphically displaying the entire EPON network architecture. When the coverage area of an EPON network is 20 km or even 60 km, and when the NMS displays ONU equipment in the EPON network in a map mode instead of a networking mode, the NSM map mode displays the geographical positions of the ONUs, and the map mode is more visual, convenient and quick to know the positions of the ONUs in a scene with more quantity; one or more ONU devices in the same geographic position can be selected for checking and configuration quickly and intuitively, and the operation and maintenance efficiency of the EPON network is improved. In order to realize the map mode, the NMS must acquire the geographical position of each ONU device, and the geographical position information of each ONU must be recorded when the ONU is installed, so that the NMS is imported, if the ONU position is changed in the later maintenance, the corresponding ONU is difficult to find and make corresponding modification. The entire import and modification process is relatively labor intensive and prone to errors.
