Crystal Head Manufacturers teach you to distinguish between good and bad network cable crystal head
Look, look crystal head color, high-quality crystal head color Qingming thorough, no noise, no miscellaneous grains;
Second, look at, look at the first crystal thickness, quality of poorer quality crystal head crystal head thick uniform, angular;
Three smell, smell the smell of crystal head, crystal head high no savor, no smell, no smell, no odor;
Four pressure, elastic pressure crystal head, crystal head high elastic, poor quality crystal head thin and weak;
Five engage, engage crystal head voice, crisp sound quality crystal head, behind that clip is even more evident.
Crystal head on the one hand, it is not easy to card tight，On the other hand is easy and copper cable disconnected
Just pay attention to the following points on the line
1, Your crystal head clamp, insulation must take the wallet into the crystal head, because it is in fact wearing twisted pair, clip into the crystal head, you can reduce the tension inside your head as much as possible.
2, Crystal head clamp, preferably with international standards to fight wire, wire non-standard way, and often make your communication much slower than your standard hardware platform, as standard wire, there are two international A international B, with the host switch usually AA, that is a positive jump, two-plane interconnect with AB, that is, anti-jumper! (If you want to know the definition of A and B is defined, I asked the bar posts)
3, Crystal head has its inherent standard, you do not have professional tools to detect, that I teach you the most simple way, you try a head clamp, then insert the card or switch can hear a "click" sound Cui Xiang, then when pulled out, the card will not astringent, namely General Conformity, if you want to measure the first crystal material, the best way is that you swing around the pond around the card, it is when you're going to break it, if good crystal head, even if you ten strokes shake, it will not break, then plug an interface, you can still hear the crisp sound, if it is poor, Oh, shake or two, the result is I do not say it.
