A RP repeater is a connected device that works at the physical layer. It is applicable to the interconnection of two identical networks, and its main function is to expand the network transmission distance by resending or forwarding data signals. A repeater is a network device that regenerates and restores signals: a physical layer device of the OSI model.
The repeater is used to extend the network distance in the local area network environment, but it belongs to the network interconnection device, operating in the OSI physical layer, the repeater has the function of amplifying and regenerating the signal on the line, and is used to extend the length of the LAN network segment (only used to connect the same LAN network segment).
RP repeater (RP repeater) is a device that connects a network line and is often used for bidirectional forwarding of physical signals between two network nodes. The repeater mainly completes the function of the physical layer, is responsible for transmitting information on the physical layer of two nodes by bit, and completes the function of copying, adjusting and amplifying the signal, so as to extend the length of the network. Due to the loss, the signal power transmitted on the line will gradually decay, and when the attenuation is to a certain extent, the signal will be distorted, so it will lead to reception errors. The repeater is designed to solve this problem. It completes the connection of physical lines, amplifies the attenuated signal, and maintains the same data as the original. Under normal circumstances, the two ends of the repeater are connected to the same media, but some Repeaters can also complete the transfer of different media. Theoretically, the use of Repeaters is unlimited, and the network can therefore be extended indefinitely. In fact, this is not possible, because the delay range of the signal is specified in the network standard, and the repeater can only work effectively within the prescribed range, otherwise it will cause network failure.
