Basic Cable Network Engineering

Sometimes the cable network is still considered such a problem for some people; distinction cable to connect PC to PC and PC to Hub / Switch different remote. To lay fallow in terms of network technology, this is certainly confusing.

In the networking world, some known type of cable is often used. Each type of cable has the ability and a different specification, because it was created by introducing the type of cable. There are two types of cable that is known in general, the twisted pair (UTP unshielded twisted pair and STP shielded twisted pair) and coaxial cable.

Image under this category is the type used in cable networks (cable category).

Giving 1/2/3/4/5/6 category is category specifications for each cable and copper for the jack. Each revision is a series of top quality cable, cable quality packing (insulator) and also for the quality of "entanglement" (twist) of each cable pair. In addition to determining the amount of frequency that can be through the means of the cable, and also so that the quality of the insulator can reduce the effect of induction between cable (noise can be pressed in such a way).

While for the coaxial cable, the two types, namely thick coaxial cable (middling large diameter) and thin coaxial cable (small diameter).
Thick coaxial cable (coaxial cable "fat") based on a specified standard IEEE 802.3 10BASE5, where cable has an average diameter of 12mm, and is usually given a yellow color; this type of cable is referred to as the normal or standard thick ethernet Ethernet, or only abbreviated ThickNet, cuman, or even referred to as the yellow cable.
Thin coaxial cable (coaxial cable "lean"), much used among amateur radio, especially for the transceiver does not require a large power output. To be used as network devices, this type of coaxial cable must meet the standard IEEE 802.3 10BASE2, where the average diameter of around 5mm, and are usually black or other dark color. Each device (device) is connected with a BNC T-connector. This type of cable is also known as thin Ethernet or ThinNet.

Twisted Pair
Twisted Pair Pengkabelan use a module Rregistered Jack (RJ), which is called RJ-45. Things that need to be understood is to ensure that we connect the right color on the pin RJ-45 is appropriate. And RJ-45 with the direction to the fore. There is some consensus that the order of the cable, ie: 568A, 568B or 258A. Overall consensus is that the, where the cable should go to which pin.

To order over the cable is the standard you use in general, but we can also do the cable pengurutan in accordance with our desires, of course, the consequences will happen if problems do occur in the network will make us, as we create a standard pengkabelan own.

Standard 568A (This standard is also in accordance with the standards in the Northern Telecom ISDN.

And standards for the PC connection to PC and PC to Hub, to the Straight Cable and Cross Cable.
[a]Straight Cable
Typically used to connect a PC to PC, the standard I use is TIA568A, where both ends use a model such as a picture 3.

[b] Cross Cable
While Cross Cable used to connect a PC to PC. One end has a sequence of T568A standard and use only the end of the T568B standard.

Pictures below may be able explain the difference between cross-link with the straight link connection.
