Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that the shielded network cable refers to a network cable with a shielded layer inside, and the shielded layer refers to aluminum foil and woven mesh. Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that the shielding layer of the single-shielded network cable is only one layer of aluminum foil. Screen network cables and unshielded network cables are distinguished according to the environment in which they are used. Double-shielded network cables are mainly used in environments with strong interference, and unshielded network cables are used in ordinary daily network environments.

1. Double shielding: The network cable and the unshielded network cable are very easy to distinguish from the internal structure. Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that there is a layer of metal shielding net and a layer of aluminum foil inside the double-shielded network cable. , Double-shielded network cable is also called double-screen with network cable. There are only 4 pairs of cables inside the unshielded cable.
2. Network cable: The internal cable pairs are tightly twisted together in a counterclockwise direction. The method of twisting each other is beneficial to reduce internal crosstalk and reduce external interference. In a normal network environment, weak electromagnetic interference The unshielded network cable does not cause any impact. The inner core of the network cable is twisted in pairs. The twisting distance of the network cable refers to the length of the twisted twist of the internal wire pair. The closeness of the.
Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that each pair of wires inside the network cable is twisted in a counterclockwise direction, and the lay length of each pair is different. This kind of intertwining changes The original electronic characteristics of the cable can resist a part of external electromagnetic interference, and it can also reduce the crosstalk problem caused by its own signal.
Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that when the wiring environment has strong interference, it will affect the transmission effect of the network, and severely cause the transmission signal to be interrupted. The wiring environment has high-voltage wires or audio. When the equipment has a strong current line, the network transmission signal is more unstable. In this case, a double-shielded network cable should be used to shield the strong interference signal to keep the network transmission signal normal.
3. Double-shielded network cable: Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that the wiring process is more complicated than unshielded network cables. All accessories in the wiring system are required to have shielding performance. , And a good grounding system is required. If the grounding is not good, the shielding layer will become the largest source of interference, resulting in performance that may not be as good as unshielded twisted pair cables, so use shielded network cables when necessary.
