Biggest signal transformer manufacturer in China

1. What are the specific classifications of signal transformer?

Signal transformer includes T1/E1 isolation transformer; ISDN/ADSL interface transformer; VDSL high-pass/low-pass filter module, interface transformer; T3/E3, SDH, 64KBPS interface transformer; 10/100BASE, 1000BASE-TX network filter; DC-DC converter; Special transformers can also be designed according to customer needs.

The products are mainly used in: high-performance digital switch; SDH/ATM transmission equipment; ISDN, ADSL, VDSL integrated service digital equipment; FILT optical fiber loop equipment; Ethernet switch, etc.

Common signal transformer models include: normal temperature commercial grade: H81601S, H81621S, H1801D, H82002D, H82409S, H84801S; Wide temperature industrial grade HX81601S, HX84801S, HX82409S, HX82411S, etc., and wide temperature industrial grade HX84801SP, HX82407SP, HX84803SP, etc. with POE function.

Signal transformer is also called network isolation transformer or data pump. The name of data pump is commonly used in the application of consumer-grade PCI network card, resulting in relatively few ways for many new purchasers to find data pump products. The reason is that the name of data pump is only the name of signal transformer (network isolation transformer) in some application fields, If you are familiar with its name in the electronic component industry: signal transformer or network isolation transformer, it will be a vast world for procurement personnel;

2. Function of signal transformer

1) Main functions of signal transformer in Ethernet:

(1) Signal transmission;

(2) Impedance matching and conversion;

(3) Waveform repair;

(4) Signal clutter suppression;

(5) High voltage isolation and other functions.

The above specific applications mainly include routers, optical cats, docking stations, switches, etc;

2) Main functions of signal transformer on network card:

(1) To transmit data, the differential signal sent by PHY is coupled and filtered by differential mode coupled coil to enhance the signal, and is coupled to the other end of the connecting network cable at different levels through the conversion of electromagnetic field;

(2) It is used to isolate the different levels between different network devices connected by the network cable, so as to prevent different voltages from damaging the device through the network cable transmission.

(3) It can also play a certain role in lightning protection for equipment.

The above specific applications mainly include servers, hubs, personal computers, etc;
