Splitter - a modern solution for branching the network

Wired Internet connection is famous for its speed and the possibility of unlimited data download. The connection to the network is via a fixed telephone cable, and if you do not need the latter, then you will not have problems. However, when you need a stable Internet connection and a clear connection over the phone, you need to use a splitter. This device will create a clear and stable signal for both lines.

Description

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

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

In addition to standard devices, on the market you can find amplified variants of splitters. Such products are separated and simultaneously amplify the signal for transmission over considerable distances, which is very convenient in the absence of fiber-optic cables.

Technology

ADSL (asymmetric digital subscriber line) - the technology on which the splitter works. This has made it possible to achieve high rates of data reception and transmission in subscriber lines of telephone communication in public networks. The speed of information flow varies:

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

During operation, the device sorts the signals for the phone and Internet modems. Data streams vary in frequency: for the telephone line, only 0.3-3.4 KHz is typical, whereas the network transmits information at a frequency of 0.26-1.4 MHz. This can completely eliminate the mutual influence of devices on each other's work.

In addition, the splitter-splitter additionally built-in protection from various types of current, which can disrupt the equipment. When the device is turned on, it is possible not to be afraid of impulse overvoltages that occur during thunderstorms, short circuits, induced currents of transmission lines.

Equipment for TVs

Along with the devices for separating the signals of the Internet and the phone, splitters are used for the installation of a television network. They are common splitters, which evenly distribute the signal between different devices. The more branches from the connector, the weaker will be the transmission to each separate "box".

Very often a splitter for a TV is used to connect multiple devices to one antenna, a satellite receiver. But it's worth trusting only devices with a built-in signal amplifier, otherwise it will not be possible to get a high-quality image.

Types of splitters

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

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

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

The second thing that requires attention is the degree of attenuation of the signal, it is indicated on the body of TV sets and other devices. The lower the value, the stronger the transmission. In this case, the need for a built-in splitter amplifier will disappear.

Connection rules

In the inclusion of a divider in the network there is nothing complicated. First, the input cable is connected, and the wires that lead to the different receivers are connected to the branching connectors. But in order to provide the technique with a clear and stable signal, two rules must be observed:

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

If, after connecting the TV to the splitter, the image is doubled, then a ferrite ring must be installed between the cable and the connector for connection .
