The function of the network filter is to allow a certain part of the frequency of the signal to pass smoothly, while the other part of the frequency of the signal 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 range in which the signal is greatly attenuated or completely suppressed is called the stopband; the boundary frequency between the passband and the stopband is called It is the cutoff frequency; the voltage gain of the ideal filter in the passband is constant, and the voltage gain in the stopband is zero; there is a transition band of a certain frequency range between the passband and the stopband of the actual filter.
The network transformer specifically has 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 transformers; special transformers can be designed according to customer needs. Products are mainly used in: high-performance digital switches; SDH / ATM transmission equipment; ISDN, ADSL, VDSL, POE power equipment integrated services digital equipment; FILT fiber loop equipment; Ethernet switches, etc.
