What Is A Repeater
Jun 22, 2018

Repeater is a connecting device working on the physical layer. It is suitable for the interconnection of two kinds of networks. The main function is to extend the distance of network transmission by sending or forwarding data signals. Repeater is a network device that regenerates and restores the signal: the physical layer device of the OSI model.

A repeater is the simplest and most inexpensive network interconnection device used to extend the network distance in the LAN environment. It operates on the physical layer of the OSI. The repeater has the function of amplifying and regenerating the signal on the line, which is used to extend the length of the LAN segment (only for connecting the same local network segment).

Repeater is a device to connect network lines. It is commonly used for bidirectional forwarding of physical signals between two network nodes. The repeater mainly completes the function of the physical layer, and is responsible for transmitting the information on the physical layer of the two nodes, and completing the function of copying, adjusting and amplifying the signal in order to extend the length of the network. Because of the loss, the signal power transmitted on the online road will gradually decay, and the signal will be distorted when it reaches a certain level, which will lead to the reception error. Repeater is designed to solve this problem. It completes the connection of physical lines, amplifies the attenuation signal, and keeps the same data as the original data. In general, the two ends of the repeater are connected to the same media, but some repeaters can also complete the transfer of different media. Theoretically speaking, repeaters are unlimited and the network can be extended indefinitely. In fact, this is not possible, because the network standards are specific to the delay range of the signal, the repeater can only work within the scope of this regulation, otherwise it will cause the network failure.
