What is the function of the four pairs of twisted pair core wires?

　　The four pairs of twisted pair wires, that is, eight cores, each play an important role in data tranSMission. The following is an analysis of each pair of cores and their specific functions:

　　First, the data transmission function

　　Cores 1 and 2: These two cores are usually used for data transmission. Among them, the 1st core (white orange) is used as the positive electrode (+) for sending data, and the 2nd core (orange) is used as the negative electrode (-) for sending data. This design can ensure accurate data transmission.

　　Wire 3 and Wire 6: Similar to Wire 1 and Wire 2, Wire 3 (white-green) and Wire 6 (green) are used for data reception. Wire 3 is used as the positive electrode (+) for receiving data, while Wire 6 is used as the negative electrode (-) for receiving data.

　　Second, backup and phone functions

　　Cores 4 and 5: These two cores are usually reserved for telephone use. In early communication networks, twisted pairs were not only used for data transmission, but also for telephone communication. Therefore, these two cores can be used as telephone lines.

　　Cores 7 and 8: Likewise, these two cores are reserved for telephone or other communication purposes. This design provides additional communication flexibility.

　　III. Anti-interference and stability

　　The four pairs of core wires of the twisted pair can be tightly twisted together to offset external electromagnetic interference to a certain extent. This special structure not only enhances the stability of the signal, but also improves the quality of data transmission. Especially in the long-distance transmission process, this design can significantly reduce the risk of signal attenuation.

　　IV. Application scenarios and flexibility

　　The four-pair core design of the twisted pair also facilitates the flexible configuration of the network. By choosing different connection methods and using different wire pair combinations, various types of network connection schemes can be flexibly constructed to meet different communication needs. This makes the twisted pair a universal and adaptable network transmission medium.

　　V. Transmission standards and performance

　　In practical applications, the performance of the twisted pair is usually related to its transmission standards. For example, the ultra-Category 5 twisted pair and Category 6 twisted pair are different in terms of transmission rate and bandwidth. But no matter which type of twisted pair, its four pairs of core wires follow the above-mentioned division of labor and design principles.

　　To sum up, the four pairs of twisted pair wires play an important role in data transmission, backup and telephone functions, anti-interference and stability, as well as application scenarios and flexibility. This design not only meets the requirements of modern communication technology, but also ensures the stable operation of the network and the reliability of data transmission.
