Installation of devices

And the axis here is the fault of nutrition: how to squeeze the torsion of a pair of 8 alive? And even the connector itself is “tightly” attached to the dart. So now I have to call the provider again, call the counterfeiters, and pay them for their work?

As it turned out, the scheme for wrapping a twisted pair is not so complicated anymore.

It is entirely possible to make such a connection with your own hands.

Before that

twisted pair

, Connections that are made with your own hands, to save a particular budget. And as soon as we get a cable for the Internet, we’ll try to connect immediately. First of all, you should understand that the Internet cable itself and how to connect it to the connector for proper operation.

Wire, plug and crimper

The Internet cable contains 8 copper cores, which are twisted in pairs.


The very same name is similar to twisted pair wire.

The twins lived in similar colors. For example, a couple could have blue and blue-white or brown and brown-white colors. and material, you can begin to select the option for which pressing will be carried out.

In addition, it will depend on the speed of transmission of Internet traffic and other information, and the types of devices for which the cable will be connected.

There are two types of switching: 568 A and 568 V. There are two types of switching - direct switching or cross-connection (cross).

Until then, it is clear that the disintegration is forgiven, then.

  1. the compression of bet twists is 4 darts, not 8. However, with such an increase in speed, traffic speed decreases from 1 Gbit/sec to 100 Mbit/sec.
  2. It is necessary to look at the skin options side by side and start with the simplest ones.
  3. Direct to 4 and 8 wires 568V
  4. This pair, which compresses any connections in a 2-pair way, is used when connecting the computer to switching devices, such as a modem, router, etc.


When pressing on both sides, the sequence of darts on the contacts is as follows:

orange with white;

  1. the compression of bet twists is 4 darts, not 8. However, with such an increase in speed, traffic speed decreases from 1 Gbit/sec to 100 Mbit/sec.
  2. It is necessary to look at the skin options side by side and start with the simplest ones.
  3. Direct to 4 and 8 wires 568V
  4. orange;
  5. greens and whites;
  6. greenery
  7. This color layout leaves 4, 5, 7 and 8 contacts unused.
  8. In this way, you can connect to the Internet via an ADSL line with a speed of no more than 100 Mbit/sec, but with a pair of 4 wires, it is much easier to install.

This pair, the connection of which is high-quality, is effective when pressing the vicor of all 8 darts.

This scheme for connecting the cable cable allows you to increase transmission speed up to 1 Gbit/sec.



The procedure for refinancing live for quotas is as follows:

  1. Direct to 4 and 8 wires 568V
  2. greenery

After this, it is necessary to carefully straighten the veins, stretch them out in the required sequence, and cut them so that the edge is perfectly perpendicular.


Then, along the grooves located in the middle of the plug, wind them in the middle in such a way that the smell goes into the contacts of the plug.

External isolation of the tree can also go in between.

Otherwise, after many peregins, the rose does not fade and lives are broken.

Afterwards, you can crimp the wires to another place where they are fastened with a crimper, which has a special groove for the 8P hem wire.

If the compression is enough, then the contacts are pierced with insulation of the veins.

This action has two functions – creating a special contact and additional fixation.


Following the instructions exactly, the twisted pairs will operate as intended.

How things went wrong, the colors were mixed up, then there was a need for such a supply of plugs, which was what was being predicted. Pressing without tools, not so foldable, and similar to a robot under the skin's power, without any special lighting.

The main thing, as in any robot, is respect, accuracy and precise instructions (pictures of various cuttings and more).

And he has no sense in calling the master, checking on a new one and paying pennies for the work that he could have done with his own hands.

If you doubt your own strength, then, obviously, you can trust it to a professional, but still try to squeeze it yourself without getting into trouble.
You can spend the least amount on plugs, but you can protect them decently.

What is the capacity of 100 Mbit/s twisted pair (all 8 wires are compressed) and 100 Mbit/s (4 wires are compressed), what are the pros and cons? A bit of theory

When the betting spins are different, to maintain the speed of 100 Mb/s, several fractions are used. (Behind the clothes is an orange green pair.):
Most of the time, other darts are not victorious.
Therefore, they are used for: connecting another PC from the same port, or two analog phones, or connecting IP phones, or connecting with PoE (Power over Ethernet) without having to worry about transferring electricity.
At 1000 Mb/s all 4 bets are vicorized.
That's it for all the wires.

There, cross-beliefs are held together in a completely different way.(For 100 Mbit, 2 bets are entered into):
: 1, 2, 3 and 6 contacts... for the cross change 1 to 3 contacts and 2 to 6.

I'm just wondering...

100BASE-TX, IEEE 802.3u – a development of the 10BASE-T standard for vicinity at the edges of the “star” topology.

A twisted pair of category 5 is used, in fact, only two unshielded pairs of conductors are used, duplex data transmission is supported, up to 100 m (div. centuries).

Wonderful... I think... Well, part 2, so 2 - so that the conveyor production of 4 pair 5E cables is already worth thinking about using 8 conductors, which is the 5th, so 5E categories in 100 metropolitan areas , as soon as possible Vlasna 2 pairs work on 100 Mbits, without problems, but what’s most annoying is to wonder why 4, 5, 7, 8 explorers don’t take part in the 5th category.


So, is it possible to use 8 contacts at the switch port, which cannot be used with a 5E cable for speed up to 1000 megabits?


This food must be supplied to the growers. I think this is due to the fact that in the warehouse there were more such connectors (sockets) and equipment for soldering was set up for them. Visnovki

1) Schodo calculation real quickness You need to use the ping command.

2) As a rule, in order to distribute the Internet to four subscribers with a speed of 1 Mb/s, it is not obligatory for the provider to have a channel of 4 Mb/s. There is a special formula for calculating optimal fluidity

.

This is explained by the fact that far from forever all 4 subscribers will download/upload at the same time.
As a rule, the provider does not guarantee speed, but it seems that it is possible.

  8. There are 2 color schemes for pressing the classic 8-core pair of torsions. I don’t know why, but in our latitudes another pressing scheme is the most popular - just scheme B.!

The massacre will be unnecessary for connecting 2 computers directly, without active intermediate control, which is available in the corresponding section below.

Yak shvidko squeeze a twisted pair

  1. If you need to create a patch cord, but you don’t know in what sequence the bets will be distributed, and you don’t have the Internet at your fingertips and there’s no one to ask for power, there’s a simple option:
  2. Let me be sure that you are still alive
  3. We squeeze the first connector
  4. Let's take the same sequence from point 1
  5. We squeeze another connector

Ready! Respect - absolutely not wrong approach . So you can only work in even more

If you have forgotten/don’t know about the two secretly used compression schemes, ask/confirm to no one, and a working link is still needed.
As soon as the edge requested, the Internet went up - we go to this side and drag the edge cable behind the circuits, which were important!

    Sometimes it is not 8-wire, but 4-wire twisted pair.

    Patch cords can also be obtained with this help. Please pay attention to the link between edge structure

    let's keep the edges 100 Mbit/s will be interconnected. Such a cable is crimped into either scheme A or B, just the contacts of the blue and brown pairs are left empty.

    But, at the same time, you will need some basic skills in working with tools.

    In order to make the presentation as quick and clear as possible, it is necessary to remember about the great number of very interesting nuances - all of them must be carefully followed.

    See the torsion of the bet Today, this pair is a type of cable that consists of a bunch of conductors twisted together in pairs. Cable

    this type

    It has double insulation.

    1. There are no different types of cable of this type. The greatest expansion of such modifications:
    2. unshielded, UTP (Unshielded twisted pair)– the screen is dry all the time;
    3. foils, FTP (Foiled twisted pair)– there is a special ball made of metal foil, which acts as a protectant against electromagnetic transients;
    4. shielding, STP (Shielded twisted pair)- There are two screens, for the skin there was a okremo and a zagalny one;
    5. foils, shielding, S/FTP (Screened Foiled twisted pair)- The screen is made of copper braid, the skin is also covered with copper foil;
    6. no protection, U/STP (Unshielded Screened twisted pair)– the cover screen is exposed, but the skin vein is insulated with foil; screen theft, F/UTP (Screened Foiled Unshielded twisted pair)- Є two

    stale screen (Equal foil and copper).

    1. Depending on the variety, the skin conductor can be either rich-core or single-core.
    2. Also, the cable that can be seen differs not only by the type of shielding, but also by the method of sealing.
    3. Today it is often possible to obtain sales of the following modifications (all of them will be assembled for the installation of SCRAP):

    CAT-6 - data transmission speed is set to 10 Gbit/s for a distance of up to 55 m;

    CAT-6a - speed of data transmission up to 10 Gbit/s to a distance of up to 100 m;

    CAT-7a – transmission speed up to 40 Gbit/s on a distance up to 50 m, up to 100 Gbit/s on a distance up to 15 m.

    crossover (sometimes called “gateway”) – interlocking to connect two some of the cards various PCs.

    The same overlapping connection diagram is used for connection



    personal computer

    to older switch models.



    The first option is often used when a twisted pair with internal crossovers is required, so it is called a crossover.

    It is most often used for small local connections, such as pairs of PCs connected directly to each other.

    Tools and materials



    To carry out such a simple process as pressing twisted pairs, the necessary special tools and materials are:

    To make the robot handy, you will need a special mounting bracket, which can be purchased at any hardware store.

    For this reason, the use of emergency and clerical services is entirely permissible.

    This item is needed to create underground insulation.

    This is necessary to gain access to the other veins.

    It is necessary to wrap the material as carefully as possible, to avoid any damage to the conductors. It is understood that special ticks may be in daily use for any reason. This is not a big problem; pressing can be done using a regular knife, a slotted screwdriver, or an object that has a similar shape.

    The process of pressing twisted pairs 4 wires

    • Since there are special pliers for pressing stranded steam, the pressing process becomes cumbersome.
    • Folds up
    • operation given

    in many stages. Regardless of simplicity, you need to wrap them up very carefully.

    This will allow you to avoid the difficult problems in the adjustment process.

    A sharp tool for pressing the RG-45 connector can be expensive.


    Therefore, buying it for one or two times does not make sense.

    • Ale, at the same time, it’s still necessary to squeeze it out.
    • The way out of this situation is an initial slotted screw with a thin, even thin working part.
    • You will also need a clerical or some other kind of twister.
    • The process of pressing the connector with additional twisting includes the following main stages:


    cleaning the twisted pair for insulation for a sufficient amount of time;

    sorting out colors, choosing the necessary order;

    using tweezers or simply using your fingers to separate the wires along the gutters; Place the connector on a hard surface with the contacts facing up, then press them in with maximum force (with the skin pressed together), being careful to do so. Photo: pre-pressing for additional spline screws

    Once all the contacts have been pressed well, carefully press them into the groove, move them to the other end of the connector, and twist them. In this way, the external insulation and all around the pair of wires will be fixed. It is very important to press the edges carefully.

    It is very possible to simply not open up the thin plastic of the connector.
