What is the repeater used in the intercom system?
The network line is super long (greater than 800 meters) and is not used in the case of optical fiber transmission. Undertake the role of. There are also some manufacturers of repeaters from signal distribution, conversion role.
There are also layers of inter layer signal repeaters and networked signal repeaters, but now networking is using IP networking, with no repeaters in the center. Can only be used in analog signal networked systems.
The repeater acts as a relay amplifying signal. For example, some large residential area or special area, will have a network long distance (usually >800 meters), or because the wire diameter is not enough, resulting in network signal transmission attenuation, not the normal network, you can use the "repeater" to solve the problem.
