Right compress Internet cable

Correctly crimping the Internet cable

The cores of the data cable are made from very thin metal wires. That is why they are easy to break when used carelessly, by accident. In such situations, you’ll likely need to compress it again.

This process is not complicated, but has its own tricks and nuances. Also the implementation will need a special pliers, but their presence is not necessary – it is possible to carry out the process with a regular slotted screwdriver and knife.

Before proceeding to swage cable, it is necessary to prepare all necessary. And also to ensure that purchased those connectors which are required in a particular case. The connectors are of different types, for connecting a computer to the network usually requires the type of RJ-45.

Varieties of cable

There are many different types of cables used to create networks between different computers and network equipment.

The most common to date, three types of communication cables:

  • Coaxial (coax);
  • Optic Fiber (optic fiber);

  • Twisted Pair (twisted pair).

Coaxial (coaxial) first began to be used to build local networks of various kinds.

This kind of Internet cable compress at home is very simple; it does not even require specialized tools – just normal knife, and screwdriver. The benefits end.

This wire consists of three main parts:

  • the Central conductor;
  • insulation (pletetsya copper or aluminum);

  • the external insulation.

The speed of data transfer by this cable is only 10 Mbps. It is extremely much susceptible to various kinds of electromagnetic interference, damage of the wire of this type is very complicated and problematic. To date, practically never used.

Fibre optic (Fiber Optic) is the most modern way to transfer the data to date.

It consists of the following parts:

  • optical fibers;
  • insulation;

  • additional wire ties (some modifications).

The optical fiber is not exposed to any types of interference, the data transmission rate with it is 2 GB. The distance between individual nodes, which connects this type wire can reach 100 km away. There is only one drawback – relatively high cost.

Twisted Pair (twisted pair) is most often used to build local networks and to connect to the Internet.

It consists of the following parts:

  • 8 copper wires;

  • PVC insulation.

Can provide relatively high data transfer rate from 10 Mbps to 1 Gbps.

Twisted pair can be:

  • shielded;
  • unshielded.

Twisted-pair less susceptible to various disturbances, it is easily repaired. Properly crimp the wire for the Internet of this type is quite simple, but requires a special tool — a swage .

The arrangement

The scheme of installation of twisted pair is the order lived by color. Another name for the Pinout.

Most often today, use the following pinouts:

  • Straight-through – video;
  • CrossOver – cross.

Contacts are numbered from left to right, when copper conductors are on top, and the connector is turned to the front of the user.

Each type of wiring has its own purpose. The scheme of the first type STRAIGHT-THROUGHT (marked as T568) is designed for connecting terminal equipment (personal computer, printer) with any switching equipment (router, hub).

Cross-schema (CrossOver) is used in the case where there is a need to connect two instance of network hardware – router, computer.

Video Straight-through

Video wiring diagram called Straight-through can be realized in two ways – there are two standard:

  • EIA-TIA 568 A;
  • EIA-TIA 568 B.

Common is the first option, but there are situations in which you can implement only the second.

There are also two standard, they vary depending on the network bandwidth:

  • standard T568 B network of 100 Mbps (100 base-TXcrossover);
  • standard T568 B network 1 Gbps (1000 base-T/T4).

Today, almost all network devices can recognize the connection method on their own (have a feature called Auto-MDIX). But there are quite a large number are still operated equipment, which can not do.

How to crimp the cable Internet with your own hands

To carry out the Pinout wire ties his hands is quite simple. This takes just a few items to find and you can buy them in the nearest computer store. You also need to know the settings of your network equipment that you want to connect. As the crimping (straight or cross) is selected depending on whether Auto-MDIX.

Tools and accessories

To perform the crimping twisted-pair of eight lived to manually requires the following tools:

  1. pliers ;
  2. flathead screwdriver;
  3. the cutters;
  4. clerical or mounting of the knife.

Also, in addition to the instrument it is advisable to stock up on a few connectors, just in case the first attempt is unsuccessful.

The order of execution of the work

The process itself is not anything complicated, it is important to observe the order of actions:

  1. the upper insulation layer is cut along a length of approximately 3 cm – with stationery or mounting of the knife. It is important not to damage a single transaction – this can lead to problems with communication;
  2. after this it is necessary each of the 8 wires carefully aside;
  3. all cores are investigated in order as they should be crimped in the connector;

  4. the connector has special grooves in them and insert each conductor in order.

When all the above operations are completed, you must perform a pressure test. This can be done with the help of pliers, and with a conventional slotted screwdriver.

Check cable

To verify crimped twisted-pair is quite simple with the help of a multimeter set in continuity mode. You must contact probes connect the wires by color – all they should prozvanivatsya. If beeps are not heard, you should put the squeeze on the contacts of the connector – they are tightly pressed against the copper conductors.

Also ping can be carried out with the help of a special device. It checks the power of the transmitted signal, respectively, this device makes it easy to detect poor-quality Pinout.

A few tips

When working with twisted pair it is necessary to observe some rules, they give the ability to avoid communication problems in the future:

  1. it is necessary to use special caps, worn to the connectors – they will save from frequent bending and breakage of the wires;
  2. the Pinout must be implemented with maximum quality – the presence of poor contact can significantly reduce the quality of communication;

  3. to avoid accidental damage to the insulation twisting also lead to a deterioration of communication;
  4. wire without outer insulation layer should not be – this can lead to their damage.

Crimping of twisted pair cable using tongs or even a slotted screwdriver is the process is not complicated. It is important to observe the technology and do everything carefully. As efficiently compressed twisted pair – a key to high data transfer speed. So before you call a technician and pay him the money, you should try to perform this simple operation alone.

To date, multi-strand twisted pair is the most popular and reliable way to transfer information over the Internet or LAN.
