SYSTEM FOR TRANSMITTING POWER, DATA AND ESTABLISHING COMMUNICATION OVER ETHERNET NETWORK Russian patent published in 2020 - IPC H04L5/20 

FIELD: physics.

SUBSTANCE: invention relates to network technologies. Technical result is achieved by a communication system for Iot devices over a cable Ethernet network, comprising: Ethernet data mixer module, as well as data for IoT devices and remote power for IoT devices, installed on one end of Ethernet cable, comprising at least two transformers, each of which has primary winding with output of middle point and secondary winding, then - PoE transformer for arrangement of additional phantom data transmission channel, an Ethernet data splitter module, as well as data for IoT devices and remote power supply for IoT devices, installed on the other end of the Ethernet cable, containing at least two PoE transformers for arrangement of an additional phantom data transmission channel, made with possibility of connection: analogue or discrete sensors, or IoT devices with a two-wire interface with power transmission, or IoT devices with a two-wire interface without power transfer and/or IoT devices with a separate power input.

EFFECT: enabling data transmission and, if necessary, powering for IoT devices over a cable Ethernet network while maintaining an Ethernet channel.
