product description:
The products are mainly used in: high-performance digital switches; SDH/ATM transmission equipment; ISDN, ADSL, VDSL, POE power receiving equipment integrated service digital equipment; FILT optical fiber loop equipment; Ethernet switches, etc.
The data pump is a device that is available on consumer-grade PCI network cards. The data pump is also called a network transformer or a network isolation transformer.
It has two main functions on a network card. One is to transmit data. It couples the differential signal sent by the PHY with differential mode.
The coil is coupled and filtered to enhance the signal, and is coupled to the other end of the connection cable with different levels through the conversion of the electromagnetic field; a
It is to isolate the different levels between different network devices connected by the network cable to prevent the transmission of different voltages through the network cable from damaging the device. In addition to this
In addition, the data pump can also play a certain lightning protection role for the equipment.
