This short tutorial is perfect for you who are making computer networks 'CHEAP' especially those composed of more than two clients who pake hubs (much cheaper than a router). To the point! What UTP cable does it? UTP cable is a special cable for data transmission. UTP stands for "Unshielded Twisted Pair". Called unshielded because less resistant to electromagnetic interference. And called twisted pair because in it there are couples who arranged spiral cable berlilitan alias each other. There are five categories of UTP cable. From category 1 to category 5. For the well-known computer network is a category 3 and category 5.
Category 3 can be used for data transmission up to 10 mbps, while the category 5 to 100 mbps. If only for example a computer network in an office or campus or a cafe, yes the most efficient use of category 3. That was more than cukup.Setahu writer there are many brands on the market, only a well-known and relatively inexpensive recalcitrant Belden is the brand - Made in USA. If you want a cheaper and use a lot, then just buy one box, approximately 150 meters in length. Do not forget to buy the connectors. The connector looks like a phone jack only bigger. Just tell me want to buy RJ-45 connectors.
One more very important, you must have a special pliers for installing the connector into the UTP cable, cool term is "crimp tool". This tool is useful to 'turn off' or 'planting' connector to the UTP cable. So once already in the 'tang', then it can not be removed again connectors. And if you want a more OK, I'll not bear it as well buy a LAN tester. You can buy the brand from Taiwan just to make it more expensive. Shaped like a box and there are LED lights and eight pairs could be blinking.
OK now you ready tools, the authors start. In general, the UTP cabling there are two types: straight type and cross type. Called straight type because each cable 8 that corresponds to the number of 1-1 directly. While called a cross because there are crosses on the composition of the cord. Confused? OK! For the straight type is used to connect the cable from the client to the hub. As for the type of cross is to a client directly connected to the client (cpu to cpu) or also from hub to hub.
We'll talk a straight type This type is most easily made. Why? Because the direct correspondence 1-1. Standard sequence like this (viewed from the connector hole, from left to right - see Figure 4): 2 orange - green 1 - 2 blue - green 1 - 2 brown. 2 orange orange young couples here means the same old orange and so on. But do not come standard staining was also not really an issue. The important thing is the order of the cord. For example the first tip pin of the first order of young orange, then the other end of the first pin order must also be young orange, so between the end of each disconnected. Actually, not all pins are used.
