Is the network cable divided into positive and negative?

　　First of all, we need to clarify the basic structure and design principle of "network cable". The core design of network cable, especially the most commonly used twisted pair (such as super five-type cable, six-type cable, etc.), is to tranSMit data signals. In twisted pair, it usually contains four pairs of different-colored wires, which are arranged in a specific way (such as orange-white, orange, green-white, blue, blue-white, green, brown-white, brown), and each pair of wires is twisted together to reduce electromagnetic interference.

　　Now, analyze the question "Is the network cable divided into positive and negative?":

　　RJ45 interface design: The network cable is usually connected to the device (such as computer, router, switch, etc.) through the RJ45 interface. The design of the RJ45 interface is standardized, which means that no matter how the network cable is inserted, as long as the color order of the cable is correct, it can work normally.

　　Wire sequence standards: For twisted pair wires, there are two main wire sequence standards: T568A and T568B. These two standards are only slightly different in the color sequence of the wires, but they both ensure that the network cable can transfer data correctly. In practical applications, the T568B standard is more commonly used. Importantly, as long as the same wire sequence standard is used at both ends, the network cable can work properly.

　　There is no difference between positive and negative: Due to the design of the RJ45 interface and the line sequence standard, the network cable itself does not have the so-called "positive" or "reverse". As long as the line sequence at both ends of the network cable is the same and the RJ45 interface is correctly inserted, the network cable can transmit data normally.

　　In summary, the network cable itself is not divided into positive and negative, as long as the line sequence is consistent and connected correctly, it can work normally.
