Wired Internet connection is famous for its speed and the ability to download unlimited data. Connection to the network is carried out via a landline telephone cable, and if you do not need the latter, then you will not have any problems. However, when a stable Internet connection and a clear telephone connection are required, a splitter must be used. This device will create a clear and stable signal for both lines.

Description

A splitter is a compact electronic device that filters digital signals with different frequencies. The presented device allows you to connect several types of equipment to one coaxial line. For example, TV and modem.

Structurally, it is a connector that is equipped with several ports for connecting devices. The main parameter that characterizes the splitter is the number of connectors for connecting devices. Their number varies from 2 to 16 andmore. The more ports, the more functional the device is considered.

In addition to standard devices, you can find reinforced versions of splitters on the market. These products separate and amplify the signal at the same time to transmit it over long distances, which is very convenient when fiber optic cables are not available.

Technology

ADSL (Asymmetric Digital Subscriber Line) is the technology that powers the splitter. This made it possible to achieve high speeds for receiving and transmitting data in subscriber telephone lines in public networks. Information flow rate varies:

  • 128Kbps to 8Mbps for user data reception;
  • from 64 Kbps to 1 Mbps to transmit information from the user.

During operation, the device sorts the signals for the telephone and Internet modems. Data streams differ in frequency: only 0.3-3.4 kHz is typical for a telephone line, while the network transmits information at a frequency of 0.26-1.4 MHz. This completely eliminates the mutual influence of devices on each other.

In addition, protection against various types of current that can damage equipment is additionally built into the splitter-splitter. When you turn on the device in the network, you can not be afraid of surge voltages that occur during thunderstorms, short circuits, inducing currents of power lines.

TV equipment

Along with devices for separating Internet and phone signalssplitters intended for the device of a television network are used. They are ordinary splitters that evenly distribute the signal between different devices. The more branches from the connector, the weaker the transmission to each individual "box" will be.

Very often a TV splitter is used to connect several devices to one antenna, a satellite receiver. But you should trust only devices with a built-in signal amplifier, otherwise it will not be possible to get a high-quality image.

Varieties of splitters

Each of the splitters has its own special functionality. They depend on the technology by which the splitter was produced. This results in two main varieties:

  • PLC-devices work with radio waves in the range from 1260 to 1650 nm, which allows them to be used in most modern networks.
  • FBT-devices are able to unevenly distribute the signal for several sources.

To choose the right device for your network, you need to focus on two parameters. The first of these is the signal frequency required for the receiver to work. It is necessary that the splitter works in the same range.

The second thing that needs attention is the degree of signal attenuation, indicated on the body of TVs and other devices. The lower the value, the stronger the transmission will be. In this case, the need for a built-in splitteramplifier will fall off.

Connection rules

There is nothing difficult in including a divider in the network. First, the input cable is connected, and wires are connected to the branching connectors, which lead to various receivers. But in order to provide equipment with a clear and stable signal, two rules must be observed:

  1. Introduce an antenna splitter into the system in front of the active equipment.
  2. Do not connect two splitters together.

If after connecting the TV to the splitter the image began to double, then a ferrite ring should be installed between the cable and the connection connector.
