Does a long network cable affect the network speed?

The telecommunications box came out of the ** line. Normally, it is OK within 3 km. 3 kilometers away may not be stable, complaints telecom they will come to help you change the first line, because this time is long, the wind and rain outside will be the line and interface aging will affect the speed.

And the ADSL at home must be connected from the bus of the ** line, and the signal will be broken when it is connected from the extension. If you are a cat out of the computer network cable, it is normal to be within 100 meters. Otherwise, it will have a big impact.

There is no impact...Because the signal travels at the speed of light. Hehe.

How far is in an instant...Hehe.

It is estimated that there is a problem with the network cable**. Or maybe there's a problem with the telecommunications bureau...

The speed of the Internet is mainly controlled by the network leader, of course, it has a certain relationship with the network card, network cable and other network equipment, and it is best to buy the best brand if there are conditions. Note that the length of the network cable should not be too long. I have tested 80 meters and 140 meters of the same brand network cable, 80 meters can be passed, the data loss is 25, and the data loss is 75 at 140 meters.

Generally speaking, the parameter allows the range unless your **line quality is too poor. There are a lot of distractions, and one is fine. You call the telecom customer service. You're looking to see if it's your cat's problem.

Yes. The fiber should be pulled at such a distance.

The network cable can only be pulled for 70 meters.

After that, the losses are huge, as the upstairs said.

Beyond 100 meters, it has a relatively large impact.

The theoretical distance of the twisted pair is 100 meters.

There will be an impact, and the network cable also has an aging phenomenon, so the network cable will affect the network speed. The quality of the network cable has a lot to do with the network speed. The network cable has an impact on the network, first of all, the quality, under the premise of ensuring the quality, the wiring should be concise and not entangled.

In addition, the twisted pair should not pass near electrical appliances such as TVs, more than 15 meters will have a certain attenuation of the signal, according to the quality level of the domestic network cable, more than 90m will have problems, more than 100 meters can not be used.

Extended Materials:

The network cable should not be too long, if it is too long and there is no signal, then there is no other solution. Theoretically, the maximum length of a network cable cannot exceed 100 meters. If the network cable has strong performance, tensile resistance and shielding interference, the longest length can reach about 120, and it is not recommended to be longer.

The reason why the network cable should not be too long: the computer can only recognize the language 0 and 1, and the network has to transmit signals 0 and 1.

These signals become current when they pass through the network cable, and the current intensity of the network cable is between -15V and +15V, and there is resistance when the current is transmitted through the network cable. Therefore, according to the principle of high-voltage transmission, the longer the line, the greater the voltage level must be used to transmit electricity. If the network cable is too long, but the voltage is so low, the signal will be weakened until it is lost.

Therefore, the network cable should not be too long.
