After finishing the circuit transformation, many people saw the worker's line drawn straight, the socket and the net mouth, the wires and the network port, and the phone line left a lot of them. Then they started worrying about the construction at the back, and as a result, they found out soon after the call. When there is noise in the handset, watching television images is blurred, and accidentally dropped when surfing the Internet, the above problems are related to the transformation of weak households. Cables, telephone lines, and cable television lines are weak households. Due to the extraordinary nature of their functions, construction methods are different from ordinary circuit construction. The weak electric wave is very sensitive, and the anti-interference ability is poor. Therefore, the sheath line protection alone cannot completely reduce the response to the near-field wave. When laying the circuit, if the horizontal distance between weak current and strong current is too small, it will easily cause signal interference in the future.

problem analysis
These problems are related to the transformation of the weak points of the family. Cables and telephone lines Cable TV belongs to weak households. Due to the special city's industrial and commercial construction and ordinary circuit construction is different.
Weak electromagnetic waves are very sensitive and have poor anti-interference. Protection by sheath line cannot completely reduce the response of nearby waves.
solution:
1. The weak wires of telephone lines, network cables, and TV lines should be individually worn in the circuit construction. They must not be put in the same pipe to avoid signal interference.
2. Between weak current and weak current, the horizontal distance between weak current and strong current should not be less than 50CM to ensure that the signal is not interfered.
3, the network cable can not be in series: cloth network cable is best to use the regular manufacturers of five types of shielded cable, not to replace the ordinary 8-core cable, poor quality cable will cause signal attenuation, reduce network speed. Do not connect the hubs in series when installing the network cable. Although the wiring is convenient, it will greatly increase the signal loss in the future.
