In the metro station scenario, Huawei's FTTM solution leverages passive aggregation and long transmission distance, providing high security and easy deployment for station networks. Passive optical splitters are used for network aggregation, reducing ELV wells and cabling footprint at stations, simplifying network deployment, and mitigating fire risks. Self-growth networking facilitates fast deployment of new IoT connections in smart stations. Huawei OptiXstar T823E-D is an industrial ONU that provides 10G bandwidth and can work within a wide temperature range of –40°C to +70°C. In addition, it supports Type B and Type C full-link protection, providing highly secure and reliable network bearing for various intra-station services.
