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.

The repeater works at the physical layer of OSI and is the center of all nodes on the LAN. Its function is to amplify signals, compensate for signal attenuation, and support long-distance communication. Repeater. Working in the physical layer, it only plays the role of extending the transmission distance and is transparent to the high-level protocol. In fact, the network connected by repeaters is equivalent to a larger network composed of the same wire. Repeaters can also connect networks of different transmission media (10Base5 and 10Base2) together, and are often used in the interconnection of the same LAN above the data link layer.
