How to distinguish the authenticity of the super five lines, and what is the difference between the

The most common fake network cables on the market are up to three categories, four categories, fake five and super five lines; Or counterfeit famous brands with miscellaneous brands. So, how to distinguish the real from the fake?

First of all, distinguish from the network cable identification. The identification of the three types of lines is "cat3", with a bandwidth of 10m, which is suitable for a ten-megabit network, which has been basically eliminated; The identification of the Category 5 line is "cat5", with a bandwidth of 100m, which is suitable for networks below 100 megabits; The logo of the super cat5e line is "cat5e", with a bandwidth of 155m, which is the current mainstream product; The identification of the Category 6 line is "cat6", with a bandwidth of 250m, which is used to set up a gigabit network, which is the trend of future development. Secondly, by looking at this approach, we can distinguish most of the false Category 5 and Category 5 lines.

The characters printed on the plastic foreskin of the true Category 5 Thread** are very clear, sleek and largely non-jagged. The handwriting of the fakes is of poor printing quality, some are not legible, and some are severely jagged. **The Category 5 line is marked with the word "cat5", and the super 5 line is marked with the word "5e", while the letters usually marked with fakes are all capitalized "such as cat5" and "5e".

Secondly, feel it with your hands. If you still can't tell by "looking", you can further feel the difference between true and false 5 and 5 super 5 lines in the material through the method of "touching". True Category 5 Category 5 wire texture is relatively soft, which is mainly to adapt to the needs of different network environments, twisted pair cables generally use copper wires as the core, which is relatively soft (because some network environments may require network cables to be bent at a small angle, if the wire is hard, it is easy to cause breaking.

In order to reduce costs, some unscrupulous manufacturers add other metal elements to the copper, and the wires made are relatively hard, not easy to bend, and are easy to break in use. Decoration review network.

Again, cut with a knife. In this step, simply use scissors to remove the plastic foreskin on the outside of a small section of wire, so that 4 pairs of cores are exposed. Here we are still through the method of "looking" to further distinguish, the white one in the 4 pairs of core wires of Zhenamp Class 5 super 5 line should not be pure white, but the white color of the core wire with the pair, which is mainly to facilitate users to distinguish the line pairs when making crystal heads.

Fakes, on the other hand, are usually pure white or have an inconspicuous color. Another point is the winding density of 4 pairs of core wires, true Category 5 Category 5 super Category 5 wire winding density is moderate, and the direction is counterclockwise. False threads are usually very dense and may be clockwise (less), mainly because they are easier to make, so the production cost is smaller.

Finally, burn it with fire. You can test the twisted pair cable in a high-temperature environment to see if the rubber outside the network cable will become soft at 35 to 40. There are also real network cables outside the glue is flame retardant, while some fake ones are not flame retardant and do not meet safety standards, so you may wish to try them when buying. ｜

CAT-5E is a CAT5e network cable, while HSYV-5E is a CAT5e twisted pair cable, the two have different names, but they are used on the network is the same, so the two are the same thing.

UTP stands for Unshielded Twisted Pair, which means unshielded twisted pair. 5E means CAT5e cable, and UTP 5E means CAT5e unshielded twisted pair cable.

The Category 5e unshielded network cable is composed of an unshielded twisted pair cable of a certain length and an RJ45 crystal head, and there are 8 network cables in the line, each two of which are entangled, so there are 4 network cables, and the reason for this is to reduce the impact of electromagnetic radiation and external electromagnetic interference as much as possible.

Main uses: Category 5A twisted pair cables are mainly used for communication companies or network companies to deploy outdoor short-distance links.

The maximum effective communication distance of ordinary Cat5 line is 100m, and the maximum communication distance of Cat5e can be 300m. And the service life of the outer protective layer is much longer than that of the ordinary Category 5 line.

Most of the wires connected to the router or switch from the cell gateway or the whole floor gateway are Category 5e cables.

1. If it is not tested by the instrument, it is difficult to see whether the network cable can reach the super five categories.

Even if a very experienced construction worker sees a piece of network cable, it can't be said whether it can reach the super five categories. However, according to the following criteria, a rough evaluation of the network cable can be made:

1. The larger the diameter of the bare copper wire in the core, the better. The manufacturing diameter of the core of the normal Cat5e wire network should be 24AWG, which is between the limit and the millimeter according to the interpretation of the UL standard; According to the interpretation of the national standard as millimeters. If the core inside is too outrageously thin, it will definitely not reach the super five categories.

But the difference of millimeters is already difficult to see with the naked eye, so we have to use a micrometer.

In addition, the above is only a manufacturing standard, and what is really used is its electrical standard, which needs to be tested by borrowing a professional tester (generally tested with Fluke test). If there is a manufacturer who can achieve the diameter of the first core bare copper wire to achieve 26AWG (mm), it can only mean that the manufacturing process is more advanced.

2. The denser the lay, the better. The layup of the four pairs of the super five network cables is different, and the general layup dense and uniform network cable can better play the role of the twisted pair to cancel out the electromagnetic interference signal sent by the core. to improve the transmission efficiency of twisted pairs.

Second, the authenticity of the network cable can only be identified by the manufacturer. If the manufacturer says it's true, it's true, even if the network cable you get in your hand is not produced by the original factory, but produced by the manufacturer's authorized factory, this is also true, because the manufacturer recognizes it. What the manufacturer says is fake is fake.

There is no direct and inevitable relationship between the real and the quality of the network cable, the real network cable also has substandard products, and the fake network cable also has standard products.
