🔀 How to crimp twisted pair at home: a sequence of actions, wire layout tools

Internet has long been firmly established in every house. It is accessed using UTP 5e cable - "twisted pair". Crimp twisted pair cabling, connection to the computer and the preset network connection is performed by representatives of the provider. But what if you needed to move the access point to another room, they organize several pieces or just replace the collapsed connector? In this case, you need to know the pinout diagram of the RJ-45 by color, which need a tool, how to use it and whether it is possible to do without special obzhimnika. These and some other questions this article will answer.

What is the crimp twisted pair and why you need it

Crimp or network cable pinouts - the distribution of the individual wires of the UTP cable in a certain order and implementation into the RJ-45 connector. There are several schemes crimp twisted pair and RJ-45: the line, cross, or 4 to 8 strands.

Important! Even if the pinout is made in accordance with the selected scheme, comply cabling "twisted pair". Their violation can lead to a significant reduction in the quality of communication:

• You can not bend the cable strongly. The minimum radius for UTP 5e is 10 diameters, i.e. about 49 mm;
• can not twist the excess cable in the "rings" - it will cause electromagnetic interference;
• strictly forbidden to lay twisted pair near wiring. The minimum distance for horizontal laying - 50 mm at the vertical - 300 mm.

What we need a tool to crimp twisted pair

A special tool is used to crimp rj 45 - Crimper. You can buy it at any electronics store and in most computer equipment stores, where there supplies department. However Crimper cost is quite high and buy it only for a one-time operation impractical. There are alternatives to the connector connecting with a conventional flat screwdriver. However, in this case it is recommended to buy a few back-up connectors in case the pile will not work the first time.

Tool for crimping connectors rj-45 has several work areas, using which you can perform all the necessary actions to the cable:

1. Removing foreign total isolation.
2. pruning wires to the desired length.
3. Crimp.

How to crimp a twisted pair of 4 and 8 cores

There are two main standard wiring layout - T568A and T568B. In addition, it is possible to transmit information signal with only four instead of eight lived.

The order of arrangement of wires is regulated by two standards: T568A and T568B

What is the difference between standards T568A and T568B? Let's start with the fact that currently almost universally used newer T568B standard. It was originally developed for feedback with uCoz - content management system from uKit Group companies. However, at present public reports were so widespread that the T568B standard used in PC network settings as a preset pattern.

UTP cable (twisted-pair) is composed of four pairs of wires with a unique color-coded. LAN standard Ethernet 10 / 100BASE-T for transmitting information on the Internet communication protocols (TCP / IP v4 / v6) has involved only two of the four pairs - orange and green. Rest, brown and blue pairs, are used to transfer data to other network applications. For example, a fax modem connections, they are responsible for the phone.

Scheme pinouts twisted pair

There are two basic pinout twisted pair:

1. Straight.
2. Cross-(Cross-point).

Straight crimp cable internet

Direct circuit - applies if necessary to connect the PC to the hub (switch) or a router (router).

Cross-crimping network cable

Cross-(Cross-point) scheme - used to interconnect two devices of the same type - computers or routers.

Compression of twisted pair - a sequence of actions

The sequence of the easiest way to show the step by step instructions.

Illustration	Description of the action
	The external cable insulation is protected by a special semi-circular openings on Crimper. Is inserted into the working area, the tool handles are reduced, and then make a circular movement that quickly distributes the insulation around the perimeter.
	Cores are released by the length of 2-2.5 cm - so it is more convenient to work with them. Untwisted and straightened.
	Wiring located on the selected transmission scheme, aligned and cut off by means of counter blades on obzhimnike.
	The connector is a latch down. Once again verified the correct positioning of the wires according to the diagram. After that, they are inserted into the rg45 all the way, so that each of them has won a niche.
	Re-checked the correct location of the wires according to the diagram. The connector is inserted into the appropriate slot Crimper, then the handle is compressed until it clicks, which publishes the connector.

Important! If the value of the blade departure is not set, either external insulation not be cut, or the insulation of internal wiring will be damaged.

How to compress internet cable at home without special tools

Crimper - pretty expensive tool, and to acquire it for a connector is not necessary. It is possible to manage normal screwdriver. All steps up to the accommodation lived in the reservoir remains virtually unchanged, with the difference that is usually used for stripping knife for cutting the wiring and wire cutters.

Convector with wires placed in it should be laid on the table latch down. While holding both sides with your fingers, push a screwdriver on one pin, until it is completely included in the postings, punching his isolation. Sequentially repeat the procedure with all the other wires.

findings

To gain access to the Internet anywhere in the apartment an ideal option is to purchase and connection of Wi-Fi router. However, if the desktop computer you need a network cable "twisted pair" in the established place, it is best to carry out his pad under the bed plaster or in a special plastic box. Derivation of the connection point to issue a special outlet and have it connect the PC system unit via a short patch cord.
