However, the existing traditional public network wireless system cannot meet the requirements, and as the country promotes the integration of four broadband networks (smart grid, data network, video network, voice network and other four networks), the original network cannot support GE/FE interfaces at the same time. , VoIP interface, Wi-Fi interface, RF video interface, etc., cannot evolve towards future network convergence.According to its needs, Huawei has proposed a solution using XPON, which can not only provide all service interfaces, but also evolve to the Internet of Things era and build an interconnected home network.XPON uses a reliable local optical fiber network to transmit and collect information, the network is safe and reliable, and the data is real-time. Moreover, the user side of XPON products can provide rich service interfaces, such as RS232/485 interfaces, GE/FE interfaces, to meet current and future business scenarios.Beijing Electric Power has installed several OLTs in the 10kv power distribution rooms of the community centers of Zhonghong Community and Jianbang Community respectively (the OLT uploads data to the meter reading master station). The meter and meter reading ONU (Huawei MA5621/MA5621A) are installed in the building power distribution cabinet, and are connected to the meters on each floor through the RS485 bus to realize real-time collection of meter information.Due to the fiber-to-the-home project, the OLT is also installed in the power distribution room in the center of the community. Each OLT outputs 32~48 PON ports, the OPLC fiber-to-the-building, the optical splitter is installed in the building power distribution cabinet, and the fiber is jumpered through the ODF and cold-connection terminals. Go to the home distribution box, and connect to the ONU through the leather optical cable to provide users with broadband Internet access, telephone, and TV services.Copyright © 2005-2022 51CTO.COM Beijing ICP Certificate 060544 All rights reserved.
