With the rapid development of the digital economy, smart cities, cloud computing, and high-definition video services, users have placed higher demands on network bandwidth and communication quality. FTTH, as the most advanced and stable broadband access method currently available, has become an important direction for global broadband network construction. Compared to traditional copper cable networks, FTTH has advantages such as high bandwidth, long transmission distance, strong anti-interference capabilities, and low maintenance costs, and is therefore widely used in residential communities, commercial parks, industrial parks, and smart community construction.
