difference between network cable and wire head

Now is a network of the world, the network to hundreds of millions of computers, notebooks, tablets, mobile phones together. The network connection way, divides into wired and wireless two kinds. Wired connections are basically connected by a network cable. So it is necessary to know the network cable.

One, the network cable, also known as twisted pair of wires.

The network cable is 8 cores, inside has 8 lines, in order to let the signal attenuation slow some, transmits the distance some farther, each 2 root is twisted together, composes 4 pairs, therefore is called twisted pair line.

The theory of the network cable the furthest transmission distance is 100-150 meters.

Network cable core thickness, copper content, determines the transmission distance of the network cable, generally speaking, the thicker, the higher the copper, the better the quality.

Five categories, Super Five class, six class, Super Six class, are some of the standards of network cable. Specifically do not elaborate, the content of a little more, professional more strong.

Second, the line sequence of the wire head

Now the most widely circulated, is the 100M wire Head card method. The cable head with the card side facing down, there is the end of the copper piece outward, starting from the left count, divided into 12345678.

Orange white, orange, blue white, green, green white, blue, brown white, brown. This is the standard line order of the hundred trillion.

Three, network cable is 8 all all use?

No. The transmission of the network will only use 4 of them. According to the order mentioned above, 1, 2, 3, 6, network transport only use these 4 root. That is to say, we use only 4 of these lines, and we can also achieve the purpose of networking.

Four, I put 4 of network cable used for networking, the remaining 4 when the telephone line, can not?

Of course. In the decoration of the time, we recommend that you first cloth cable, so you can choose a lot of room.

Five, network cable can be a connector?

OK. But it is not recommended. Because this will enhance the attenuation of some signals, will affect the transmission distance.

Are there any arguments for outdoor and indoor cables?

Some, outdoor wiring, it is recommended that you use outdoor network cable, outdoor network cable will be somewhat different outside the skin, and some outdoor network cable, there will be more than one line, called the rib, used to keep the network cable encountered a strong external force, the inside of the line will not be broken.
