When pre-embedded network cables for home decoration, most people use unshielded cables, and some people use shielded cables. Many friends will have questions. Is it necessary to use shielded cables for household cables? Let’s take a look at this issue with everyone today!
Let’s first look at what a shielded wire is. The internal structure of the shielded wire generally has shielding layers such as aluminum foil and braided nets, which can resist strong interference environments and can effectively shield external electromagnetic interference and block cables Its own electromagnetic leakage,
Maintain the stability of the transmission network while preventing information from being eavesdropped on.
Therefore, it is recommended to select unshielded network cables for wiring during home decoration, as follows:
1. It is recommended to select unshielded network cables for house decoration network wiring. Some friends think that shielded network cables have the effect of anti-interference and effectively resist external interference to network signals, thereby increasing the network speed.
2. In fact, the operating frequency of most actual network applications is lower than 30MHz, and the unshielded
Network Cable is twisted to reduce internal crosstalk, which can satisfy the daily environmental wiring
3. In household wiring, as long as you correctly observe the distance requirements for strong and weak current, there is almost no interference. Although the shielded network cable has a shielding layer to resist interference, the shielded network cable must be shielded.
4. The entire system must be shielded accessories, including cables, sockets, crystal plugs and distribution frames, etc., and the building needs to have a good grounding system. But in actual construction, it is difficult to perfectly ground all
5. As a result, the shielding layer itself becomes a big source of interference, resulting in performance that is far inferior to unshielded network cables.
6. In household wiring, Category 5 or Category 6 unshielded oxygen-free copper network cable is generally selected, because the oxygen-free copper conductor has low resistance and stable and long transmission. But considering the stability of transmission and network upgrades,
It is best to choose Category 6
Network Cable Wiring. Category 6 network cable is suitable for gigabit networks and is compatible with 100M networks.
