Advice 1: What is the media Converter

Converter – a device that allows you to transfer data from one environment to another. This mechanism allows to link together remote objects on the basis of optovolokonnykh connections.

The market for IP surveillance is constantly growing and evolving, as confirmed by numerous studies of various marketing agencies. In this regard, the security market continues to grow, the demand for active network equipment. We are talking about routers, switches, wireless access points and media converters.

The principle of operation of the device



Media Converter – network device intended for organization of packet data from one environment to another. Thanks to such devices it is possible to create systems of enormous tension. Media converters can convert the environment of the signal. The most common medium is copper and all that it created – light fiber, copper wire and fiber optic cables, which use the principle of signal transmission over twisted pair and fiber-optic communication lines.

Businesses and organizations wishing to increase their network, very often used media converters. In the first place so an inexpensive way to connect remote departments and organizations on the basis of fiber connections, which ultimately will increase the capacity and number of end users. Media converters allow you to cheaply upgrade the local network, which still runs on copper cables without the need of full modernisation.

Classification of media converters



Media converters are indispensable in cases when you want to send data over long distances. For example, if you want to organize IP video surveillance system on the area of several km2 and to ensure the transmission of video and audio from IP cameras to surveillance post located at some distance.

The signs, which classified these devices:

1. Handling. Media converters can be managed or unmanaged. Unmanaged type cannot be configured – it works in automatic mode. In some cases, can be easily controlled by setting the chassis. The second type can be managed via web interface and SNMP.
2. Standard copper port. You can select one of the three standards modes of operation, each of which provides different data transfer speed.
3. Standard optical port. Here you can also select one of four standard modes of operation, each of which involves the use of different connectors. For example, the ST connector is suitable for multimode fiber and FC connector for single-mode fiber. The SC and LC connectors are the most popular, because it can be used for singlemode and multimode fibres, and differ only in size.

Advice 2: What is active network equipment

Network equipment, through which the user gains access to the network is divided into two types: active and passive. Under the active network equipment should first understand the different kinds of switching devices, hubs, routers, etc. To the passive network equipment includes: cables, sockets, connectors, etc.
What is active network equipment

Active network equipment



Active network equipment designed to perform a variety of actions connected with data transmission. For example, consider the routers. It is known that they transmit the special packets of information those computers that are connected to them, then they have access to the Internet. In all varieties of active network equipment organized packet transmission where each packet with different location information, integrity information and other data that allows you to deliver it to its destination.

Active network equipment can not only perform the function of transferring data packets, but also the functionality of the transmission channels. This is because the variants of data transmission in the network, there are so many that depend on network load and used/unused devices.

Network adapters connect devices to the network. Repeaters (amplifiers), as you might guess, receive and amplify an existing signal, while a person is always present the possibility of branching the same signal. Converters (used very rarely) perform conversion from one technology to another. They are mainly used where it is impossible to transmit data on a particular technology and convert it to another.

Switches, hubs, and other similar equipment allows you to combine multiple computers into a single network, that is, form the so-called logical connection between devices. Routers, in turn, distribute the data packets to computers, network segments.

In the end, active network equipment provides a construction of a distributed information structure and enables the user to send and receive certain amounts of information at a large distance (i.e. use the Internet).

Passive network equipment



As for passive network equipment, it is not powered from the mains and passes the signal without any amplification. It is divided between two groups: equipment that serves as a transmission path of data and equipment, which is a kind of route for the cables. The first group mostly include: sockets, cables etc. To the second group: brackets, kabelkanal, clips and other equipment.

Thus it turns out that the main role in creating and receiving the signal played by the active network equipment.
