1. XDSL isolation transformer is mainly used for asymmetric data transmission line (ADSL), high-speed digital transmission line (HDSL), very high-speed digital subscriber loop (VDSL), etc. This product mainly plays the role of signal distribution, filtering, impedance matching, DC isolation, polarity conversion, etc. the product has the characteristics of good shielding, strong interference ability, long transmission distance and fast speed.

2. In addition to meeting the basic conventional requirements, the main parameters of the transformer used in xDSL are t.h.d (the test values are different at different frequency points and different voltages), distributed capacitance, leakage inductance, and insertion loss of the entire passband of 0-1.1 MHz. Among them, t.h.d is the one that most affects the connection rate

3. The voice separator can effectively separate the high-frequency digital signal and low-frequency voice signal in the telephone line, forming three data channels on one line:

● a high-speed downlink channel with a rate of 1.5mbps-8mbps for users to download information;

● a medium speed duplex channel with a rate of 16kbps-1mbps for users to upload output information;

● a low-speed telephone service channel with a rate of 200Hz ~ 4kHz, which is used for ordinary telephone service.
