High Quality Bi-Directional Amplifier/Two Way Radio Repeater Booster/Channel Selective Repeater

The repeater can connect the cables of two LANs, re-time and regenerate the digital signals on the cables, and then send them out. These functions are typical of the physical layer, the first layer in the OSI model. The function of the repeater is to increase the coverage area of the LAN. For example, the Ethernet standard stipulates that the maximum length of a single section of signal transmission cable is 500 meters. However, after connecting five sections of cables with the repeater, the maximum length of the signal transmission cable in the Ethernet can reach 2500 meters. Some brands of repeaters can connect cable segments with different physical media, such as thin coaxial cables and optical cables.

Repeaters are connecting devices that work on the physical layer. It is applicable to the interconnection of two identical networks. Its main function is to expand the network transmission distance by retransmitting or forwarding data signals. Repeaters are network devices that regenerate and restore signals: physical layer devices of OSI model.
