How to distinguish the true and false of the network cable?
"Look": Different network cables have their own different logos and uses. For example, Cat5 cable, the logo is cat5, and the bandwidth is 100M, which is suitable for networks below 100M; the Cat6 cable, the logo is cat6, and the bandwidth is 250M, which is used to set up a thousand Meganet.
In addition, the factor characters on the plastic foreskin of the genuine network cable are very clear, sleek, and basically jagged; the handwriting quality of the fakes is poor, some of the fonts are unclear, and even serious jagged.
"Touch": The genuine network cable has a soft texture, and copper wire is generally used for the core; the fake one will add other metal elements to the copper, which is harder in texture, not easy to bend, and easy to break.
"Cut": Use scissors to remove the plastic foreskin outside a small section of the thread. Note that the white core should not be pure white. The paired color is gray, which is very easy to distinguish; fakes are usually pure white or the color is not obvious.
In addition, the genuine 4 pairs of cores have a moderate winding density and the direction is counterclockwise; the fake has a low density, and the direction may be counterclockwise or clockwise.
"Burn": Put the network cable in a high temperature environment of 35℃~40℃. If the cable rubber does not become soft, it is a genuine product; otherwise, it is a fake.
In addition, the genuine rubber is flame-retardant, while some fake ones are not flame-retardant.
"Test": Take a 100-meter network cable to connect the computer to the network and test the network speed of the network cable. This method can be used to test the twisting degree of each pair of wires in the network cable and whether the metal medium is qualified.
