How to test the merits of a network cable

Cable, everywhere, it also directly affects a key factor in network transmission speed can be a lot of people do not know the network cable also vary, Hong Kong Kwai Fong room --- teach you how to distinguish the pros and cons of the network cable to pass the test .
1, the test network cable flexibility
quality of cable re-do better in terms of flexibility, mainly taking into account the convenience of network cabling, anyway bending test will be very easy, and will not be broken, while the market some of the more inferior the cable is no longer so flexible, mainly due to some businesses, the originally pure copper cable in the incorporation of other metal components.
2, the test cable resistance to high temperature resistance
cable out of some perennial, must withstand wind and sun, temperature and frozen at inclement weather, the cracking can not be softened or general genuine cable capable of withstanding up to temperature of about 50 degrees, the test method may take a short cable on the hearth about 20 minutes, and then this point, if cable sheath than normal skin soft, then it shows the quality of the network cable is not perfect. Under normal circumstances, the skin network cable will have a formal identification, such as: CAT5 (Ethernet cable is five lines), CAT6 (network cable is six lines), if the skin cable without any identification, then we should be careful to buy a.
3, the test network cable combustibility
general cable has anti-combustibility, the easiest method of testing is to use lighters point of water combustion test cable jacket, the general quality of the cable point of water 6 seconds, will take white smoke, and will slowly dissolve to form, do not burn; and poor cable, two seconds after the start of ignition in the combustion, and accompanied by a lot of smoke.
4, the test cable jacket extension of the
quality of the cable should be two individual pull cable jacket, dragged continuously, not let go will restore as good degree of extension; and poor cable jacket, in particular, is easy to pull off or a crack .
5, the transfer rate test cable
It is recommended that you use dual mode direct connection to the test, but also some other factors which may affect the speed of transmission, such as the configuration of the machine itself, crystal head, network cards, etc., so try using a higher allocation of and other machines to minimize the influence of the outside world, the transmission speed of the test will be more accurate.
In short, Hong Kong Kwai Fong remind you: in your daily work, we also need a lot of heart to go shop around, do comparisons, do more tests.
