The network cable can be seen everywhere, and it is also a key factor that directly affects the network transmission speed, but many people do not know that the network cable has its pros and cons. Kwai Fong computer room in Hong Kong-teach you how to distinguish the advantages and disadvantages of the network cable by testing.

1. Test the flexibility of the network cable

High-quality network wires are better in terms of flexibility, mainly considering the convenience of network wiring, no matter how easy to test bending, and will not be broken, while some of the inferior network wires on the market are no longer so flexible. the main reason is that some merchants have added other metal components to the wire that is originally pure copper.

2. Test the high and low temperature resistance of the network cable.

Some of the network cable is out all the year round and must be able to withstand the wind and the sun, and it cannot be softened or cracked in the bad weather of high temperature and freezing. In general, the authentic network cable can withstand a high temperature of up to 50 degrees. The test method can take a small section of the network cable and put it on the edge of the stove for about 20 minutes. Again, if it is found that the outer skin of the network cable becomes softer than the normal one, it shows that the quality of the network cable is not too hard. In general, the outer skin of the network cable will have a formal logo, such as: CAT5 (network cable is five types of lines), CAT6 (network lines are six types of lines). If the outer skin of the network cable does not have any logo, we should be careful to buy it.

3. Test the flammability of the network cable.

Generally speaking, the network cable has fire resistance, and the simplest test method is to use a lighter to test the water combustion of the outer skin of the network cable. Generally speaking, the high-quality network cable will emit white smoke only after 6 seconds of water, and it will slowly dissolve and form. It won't burn, while the inferior network cable begins to burn after 2 seconds of ignition, and is accompanied by a lot of black smoke.

4. Test the extension of the outer skin of the wire.

High-quality wire should be two people pulling the outer skin of the wire, all pulling continuously, if you don't let go, it will return to its original shape and have a good extension, while the inferior outer skin of the wire will easily break or have cracks.

5. Test the transmission speed of the network cable

It is suggested that we use the method of dual-computer direct connection for testing, but there are other factors that may affect the transmission speed, such as the configuration of the machine itself, crystal head, network card, etc., so try to use higher-configuration machines to minimize external influence, and the transmission speed of the test will be more accurate.

In short, Hong Kong Kwai Fang reminds you: in your daily work, you still need to pay more attention to go to the shop, make more comparisons, and do more tests.
