What is the principle of lan transformer?

First of all, we must talk about its internal structure. Generally speaking, lan transformers are divided into T, K, and K3. The T part Transforme is a transformer part, that is, an induced voltage is induced on the secondary side of the transformer through magnetic coupling

The function of the lan filter is to allow the signal of a certain frequency to pass smoothly, while the signal of the other part of the frequency is greatly suppressed. It is essentially a frequency selection circuit. In the filter, the frequency range through which the signal can pass is called the passband or passband; conversely, the frequency range where the signal is greatly attenuated or completely suppressed is called the stopband; the boundary frequency between the passband and the stopband is called Is the cut off frequency; the voltage gain of an ideal filter in the pass band is constant, and the voltage gain in the stop band is zero; there is a transition band in a certain frequency range between the pass band and the stop band of the actual filter.

Lan transformers specifically include 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; RJ45 Integrated transformer; special transformers can also be designed according to customer needs. 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.
