如何辨別網線的真假

在組建網絡時，人們大多會重視交換機、路由器、網卡等設備，卻經常忽略網線、水晶頭和插座模塊這類設備。但你知道嗎？網線選不好，會嚴重影響網速的。
如何辨別網線的真假？
“看”：不同網線都有自己不同的標識和用途，例如五類線，標識是cat5，帶寬100M，適用於百兆以下網絡；六類線，標識是cat6，帶寬250M，用於架設千兆網。
另外，真品網線塑料包皮上的因素字符非常清晰、圓滑，基本鋸齒狀；假貨的字跡質量較差，部分字體不清晰，甚至出現嚴重的鋸齒狀。
“摸”：真品網線質地比較柔軟，線芯一般使用銅線；假貨會在銅中添加其他金屬元素，質地較硬，不易彎曲，容易斷線。
“割”：用剪刀去掉一小截線外面的塑料包皮，留意白色線芯不應是純白，與之成對顏色是花白，非常容易辨別；假貨通常是純白色或花色不明顯。
另外，真貨的4對線芯繞線密度適中，方向是逆時針；假貨密度很小，方向可能是逆時針，也可能是順時針。
“燒”：將網線放在35℃~40℃的高溫環境中，如果網線膠皮沒有變軟是正品；反之則是假貨。
另外，正品的膠皮有阻燃性，假的有些不具有阻燃性。
“測”：取100米網線將電腦聯網並測試網線的網絡速度，利用這種方法可以測試網線中每對導線的扭繞度和金屬介質是是否合格。

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.
