The Working Principle Of The Repeater
Jun 26, 2018

The purpose of repeater design is to push your network signals so that they can be transmitted farther.

Due to the influence of transmission line noise, the digital signal or analog signal carrying information can only transmit a limited distance. The function of the repeater is to regenerate and transmit the received signal, thus increasing the distance of the signal transmission. It connects two or more network segments of the same network. If Ethernet often uses repeater to expand the cable length of the bus, the maximum length of the standard fine cable Ethernet is 185 meters, and the maximum can have 5 segments, so the maximum network cable length can be increased to 925 meters after the repeater is added. In general, the network part of the repeater is network segment instead of subnet.

The repeater can connect the cables of the two LAN, retime and regenerate the digital signals on the cable, and then send them out. These functions are the typical functions of the first layer of the OSI model, the physical layer. The role of the repeater is to increase the coverage area of the LAN, for example, the Ethernet standard provides that the maximum length of a single signal transmission cable is 500 meters, but the maximum length of the signal transmission cable in Ethernet is up to 2000 meters after the use of a repeater to connect 4 segments of cable. Some brands of repeaters can be connected to different physical media such as thin coaxial cable and optical cable.

Repeaters send only data from any cable segment to another cable, regardless of whether there is wrong data in the data or not suitable for segment data.
