This paper presents a comprehensive analysis of the FTTR system architecture and protocol stack, focusing on three key technical aspects: centralized scheduling and control, integrated management and maintenance, and green energy-saving mechanisms. Wall surface installation Suitable for multiple scenarios, higher installation efficiency. One 90°corner bend (1 mm radius) with a 2 kg load. Two 10 mm diameter mandrel wraps. Thirty attachment points, as same with the actual installation. Fiber to the Room (FTTR) extends fibre optic coverage through high-quality in-building cabling to every individual room, establishing the foundation for uninterrupted gigabit connections without signal degradation. This future-proof technology combines the advantages of fibre optic infrastructure. As 200 Mbps or higher bandwidth becomes the mainstream and requirements for services such as online education, video, VR, e-Sports, and smart office increase sharply, users need Wi-Fi that supports high bandwidth, low latency, wide coverage, and multi-user concurrent access, driving operators to. Recently, the 42nd Annual Academic Conference on Communication Circuits of China Institute of Communication, themed "Communication Line in the Context of Dual Carbon and Circular Economy," was held in Shenzhen, China. Demands for high bandwidth, high bit rates in both directions, low latency, and service reliability are constantly growing. Applications such as online learning, remote work, online gaming, video conferencing, live. Optical fiber drop cable, also known as FTTH (Fiber to the Home) cable, serve as the critical final segment in fiber optic network. These cable bridge the gap between an ISP's backbone infrastructure and end-user premises, enabling high-speed internet, voice, and data service in residential.
