Problems solved by technology

In addition, the wires in the cable have the longest parallel transmission distance, so there is a large partial capacitance and mutual inductance between the wires, which will cause signal crosstalk between the wires, and common mode interference will occur when the interference voltage amplitude is the same

Description

technical field [0001] The invention relates to the technical field of computer cables, in particular to a transmission cable for computers that reduces common-mode interference. Background technique [0002] The interference radiation of cables is one of the most common problems in electronic engineering, and it is also the most important factor that causes electromagnetic compatibility problems in computer systems. Therefore, it is often found in practice that when the external dragging cable on the device is removed, the device can pass the test smoothly. When encountering electromagnetic interference in the field, as long as the cable is pulled out, the fault phenomenon will disappear. This is because the cable is an efficient receiving and radiating antenna. In addition, the wires in the cable have the longest parallel transmission distance, so there is a large partial capacitance and mutual inductance between the wires, which will cause signal crosstalk between the wi...
