Transceivers: functions and types. Network transceiver Transceiver: operating principle

Modern computer networks differ in many technical solutions.A network transceiver is a device for transmitting and receiving a signal between two physically different media of a communication system. This is a transceiver, a physical device that connects the host interface to local network, such as Ethernet. Ethernet transceivers contain electronic devices that transmit a signal into the cable and detect collisions.

The transceiver allows a station to transmit and receive from a common network transmission medium. Additionally, Ethernet transceivers detect collisions in the medium and provide electrical isolation between stations. 10BASE2 and 10BASE5 transceivers connect directly to the transmission medium (cable) common bus. While the former typically uses an internal transceiver built into the controller circuit and a T-connector to connect to the cable, the latter (10Base5) uses a separate external transceiver and an AUI cable or transceiver cable to connect to the controller. 10BASE-F, 10BASE-T, FOIRL also typically use internal transceivers. It must be said that there are also external transceivers for 10Base2, 10BaseF, 10baseT and FOIRL, which can be separately connected to the AUI port either directly or via an AUI cable.

If the transceiver is the link between optical and copper cables, then it is often called a media converter.

Transceivers: what are they and why are they needed?

Recently, such mysterious words as “transceiver”, MOXA module and others have become popular. However, not everyone yet understands what all this means. Let's start with transceivers. This word, translated from English, consists of two words at once: “receiver” and “transmitter”.

Transceivers allow various stations to receive and transmit data in a network environment. In fact, they work according to the radio station's algorithm. Modern organizations use these devices to connect to a network of computers, converting a stream of parallel data sent over the computer bus into a sequential data stream. In this form, they can already be transmitted over a cable connecting computers to a network. Transceivers are very convenient both to connect and then to use. It is enough to integrate them into the board or mounted on the cable as a separate unit. Let's say a gls-lh-sm transceiver is capable of transmitting a signal via optical lines over a distance of five hundred meters to ten kilometers. Moreover, this model has an extended operating temperature range. As you can see, it has a lot of advantages. This means that at present this is an ideal solution when building a network.

In addition, there are optical transceivers that convert the signal into the external transport medium from the network device environment (internal electrical). This new feature makes it possible to build a network with data transmission. The optical model is presented in several modules. These are X2, XENPAK, XFP, SFP. They are optimized to work with various data transfer protocols. Such a transceiver can be either built into a network device or replaceable.

Between two physically different communication system media. It is a transceiver, a physical device that connects a host interface to a local network such as Ethernet. Ethernet transceivers contain electronic devices that transmit a signal into the cable and detect collisions.

If the transceiver is the link between optical and copper cables, then it is often called a media converter.

So how can transceivers benefit you?

Purpose of transceivers

Here are just some options:
military affairs or rescue operations. During exercises or when working in extreme conditions, devices must be capable of transmitting and receiving short-wave and long-wave signals. Transceivers are capable of this; tourism and travel. On river rafting or in the taiga cellular
absent. Walkie-talkies would also work, but transceivers can transmit information between tour groups, workers or athletes;

Internet provision. Transceivers connect a computer to a global network, whatever type it may be.

Of course, the use of transceivers is not limited to this, and an experienced radio amateur will find this device indispensable in many circumstances.

Types of transceivers

These devices can be divided according to their operating frequency range:
VHF transceivers operate on ultrashort waves (30-300 MHz), and their operation is carried out only in the line of sight;
universal devices operating at long, medium, short and ultra-short frequencies.

If we talk about cost, then we have the following breakdown:

price category up to 50,000 rubles. This category is for beginners. The devices in it work great, but they are simplified and do not contain advanced functions. A good example Alinco DR-638 new and Yaesu FT-450 can serve as such devices. If someone decides to try working with a transceiver, it is better for him to purchase such a device: a neophyte in the field of radio engineering simply will not understand what to do with an expensive device, and all the value of the latter will be wasted;
price category from 50,000 to 80,000 rubles. Here the devices receive some advanced functions, but essentially remain the same. Here are examples: Vertex VX1400 and Icom IC-78;
price category from 80,000 to an arbitrarily high amount. Here you will find large-scale devices for professionals: a large number of control knobs for speed of operation, expensive circuits for ideal sound and transmission quality, high power and other points for which these devices can be considered the pinnacle of the development of radio engineering. Examples are: Yaesu FT DX 9000 MP and Icom IC-7600.

There is another classification:

amateur transceivers for organizing communication between non-professional subscribers in certain frequencies. They are convenient devices for travelers and users in offices and apartments;
professional transceivers for use in military and law enforcement agencies, to provide operational communications. Their features are a waterproof and shockproof body, independence from weather conditions, temperature changes, and a large range of action.

It is important to use licensed original devices: they will meet the requirements stated by the manufacturer and will last for a long time without crashing.
