2014-11-22 09:53:39

The Coaxial Cable is refers to the two concentric conductor, the conductor and shield layer share the same axis min heart. It is widely used in computer network. Due to its insulating material, outside the main package, there is a layer of weaving shielding wire mesh, so can block electromagnetic interference of the outside world, improve the quality of communication.
 Coaxial cable has the advantage of a relatively long reaper device support high bandwidth communication on line, and its shortcomings are obvious: one is a large volume, the diameter of the fine line is 3/8 of an inch thick, take a lot of space cable pipe; Two it is unable to bear tangles, pressure and severe bending, which will damage the cable structure, prevent signal transmission; Finally is high cost, and it is twisted pair can overcome all the shortcomings, therefore in the present local area network (LAN) environment, basic has been replaced based on twisted-pair Ethernet physical layer specifications.
