With the rapid development of society, the demand for information in all industries, departments, and home users is increasing. The development of computer communication network technology also offers the possibility of large-capacity, fast-paced delivery. Therefore, more and more The units and home users began to consider how to effectively lay out and install Fiber Optic Splice Closure so that they can easily be connected to a local area network or the Internet in the future, thereby realizing high-speed, large-capacity data, voice, and image transmission. It can be said that effective network cabling is The communications, computer networks, and other systems of the building constitute a strong foundation. So how do we close the network cable to the fiber optic splice closure? Only by fully understanding the importance of network cabling, we can make the layout of the network cable more systematic, standardized and rational in the actual network cabling process. Structured, systematic network cabling of the network allows unit users and individual users to take full advantage of rapidly developing technologies that can have a substantial impact on all systems in any device. Only by fully understanding the importance of network cabling, we can make the layout of the network cable more systematic, standardized and rational in the actual network cabling process. Structured, systematic network cabling of the network allows unit users and individual users to take full advantage of rapidly developing technologies that can have a substantial impact on all systems in any device. System layout of network lines can also be seen as a platform with good engineering performance for the entire network communication system. The use of this platform has great flexibility and versatility in the entire building or the entire communication system network communication. There is a very good performance-to-price ratio. For example, according to the author's experience in network cabling, systematic wiring of entire floors or entire buildings can reduce the maintenance personnel of network communications to half. As a systematic and structured network cabling system is a star-shaped physical structure with multiple functions, it can be applied to network systems with different topologies.
