With the rapid development of fiber optic communication technology, FTTH (Fiber To The Home) has become the mainstream broadband access solution for urban and rural areas. FTTH networks not only offer advantages such as high speed, stability, and low latency, but also meet the growing data needs of future homes and businesses. This article will use Newsun's fiber optic communication solutions as a case study to deeply analyze FTTH network design solutions, covering key topics such as network topology design, fiber optic cabling and equipment selection, construction, and maintenance management, providing comprehensive reference for communication engineers, operators, and enterprise users.
