Data pump is a device that is available on the consumer PCI network card. Data pump is also called network transformer or network isolation transformer.It performs two main functions on a network card. First, it transmits data. It couples the differential signal sent by the PHY with differential mode.The coil is coupled to filter to enhance the signal, and through the electromagnetic field conversion coupling to the other end of the connected network cable at different levels; It is the different level between different network devices connected by the isolation line to prevent the transmission of different voltages through the network cable from damaging the device. In addition, data mercury can also play a certain role in lightning protection of equipment.
