Clearly at home is a hundred megabit fiber, why do you think the network speed is slow? Many friends will have doubts ~

Exclude the possibility of being audited by the network, the home network is not good, in fact, will be related to the network cable. This is why everyone recommends using super 5 and super 6, so the question arises, isn't it more worthwhile to upgrade the network cable of category 7 and category 8? What should we pay attention to when laying network cables at home?

Today we are going to have a good understanding of those things under the network cable!

In terms of material and service life, network cables can be mainly divided into four types.

The first is the best, the material is oxygen free copper, the use of oxygen free copper network cable usually has ten years of warranty, which does not mean that it can not be used after ten years, but that the transmission rate will gradually decline after aging, ordinary household 20 years should be no problem. And the cable resistance of oxygen-free copper is small and the transmission distance is longer.

The second is the traditional network cable made of recycled copper material, but it contains a little more impurities and has a slightly shorter high-speed transmission distance. The advantage is that the price is cheaper and the life span is similar to that of oxygen-free copper. Now many ten gigabit seven, eight types of network cables are also using this traditional material.

The third is our most common network cable copper coated aluminum, simply speaking, aluminum is coated with a layer of copper, because it is cheap enough at the same time, the performance is also good. This is the six types of gigabit network cable sold on the Internet with a price of 20~30 yuan for ten meters. Transmission rate can reach 100 meters gigabit, but the service life is relatively short, about five years began to age.

The fourth is the use of aluminum, iron materials made of inferior network cable, basic two years can say goodbye to it!

In addition to the material, the core thickness and winding mode also affect the transmission speed of the network cable. Specific will not do detailed explanation, a simple understanding of the network cable is usually used in the United States wire gauge WG, the common is 232426272832 specification number represents the same area can be crammed into the AWG line number, so the smaller the number, the thicker the line, the better the quality.

Next let's talk about five categories, super five categories, six categories super six categories, seven categories, eight categories how to choose the name ~

Category 5 network cable is often referred to as the 100 Mbit network cable, and CAT 5 is marked on the outside of the network cable. More common is the super five network cable, the network cable logo is CAT 5E, improve some anti-interference ability; The most recommended type 6 network cable, marked CAT6, is not much more expensive, while the type 6 network cable adds an insulating cross skeleton, the whole network cable becomes thick and hard, which further improves the ability of anti-interference.

Super six types of network cable is stronger, generally will use 23AWG 0.57mm thick thick line, not up to this specification on the careful purchase.

Seven types of network cable is also known as IQ tax line, the specification is not much stronger than super six types of network cable, many people measured there is no much difference, the price is also a lot more expensive.

Eight types of network cables are much faster, up to 40Gbps, but also limited to the length of 30 meters, this kind of network cables are generally used in computer rooms, servers and the like, there is no great need for household use.

Finally, we need to pay attention to the network cable has gigabit, but the network port must not be inserted into the gigabit port! After understanding, you can choose the network cable?
