In order to improve the high-frequency transmission performance, the UTP cable is untwisted in order to insert the unshielded twisted pair (UTP) cable into the plug, and the twisted cable Mode crosstalk suppression apparatus for unshielded twisted pair (UTP) cable connections for eliminating unwanted crosstalk caused by nonuniformity and proximity of a loosened portion, and more particularly to a differential mode crosstalk suppression apparatus for unshielded twisted pair (UTP) An artificial pattern is formed on the front and rear sides of the printed circuit board (PCB) so that the crosstalk values of the two lines, which cause interference with each other, (Spiral) type capacitors are inserted in order to achieve the same effect as that of the inserted capacitive coupling. In order to improve the high-frequency transmission performance by suppressing crosstalk, a plurality of transmission lines are arranged. In the four pairs on both sides of the PCB substrate P, spiral capacitances are connected to the front line 1 (11) A rear line 5 'is formed on the rear surface of the front line 3 13 and a rear line 8' is formed on the rear surface of the front line 6 16 at the same position And the spiral shape of each of the lines is rotated by a curve. The thickness of the coplanarity is 0.2-0.5 mm, and the distance between the lines is 0.2-0.5 mm.
