Etherloop is a kind of “new generation” of DSL technology that combines the features of Ethernet and DSL. This technology allows you to combine voice and data over standard telephone lines. Under good conditions, it can transmit data at a speed of up to 6 megabits per second at a distance of up to ~ 6400 meters.
Etherloop uses a half - duplex mode of data transfer, which means that it is less susceptible to the influence of the quality of the communication line and shorted sections. In addition, etherloop modems can break through linear filters (although this is not recommended). This technology is used by many Internet service providers in places where the cable length is too long or the quality is too low. Some modems manufactured by Elastic Networks can be connected to each other via a telephone line and used as an extension to the LAN - in this way, you can expand the Ethernet network to cover a building that is too far away for ordinary ethernet.
