Abstract

In a 6-pin cable according to an IEEE-1394 standard, power lines and two pairs of signal conductors are built and connected to a head part provided with six electric joints corresponding to six conductors (total six two power lines and total four signal conductors). Ferrite beads respectively forming a closed magnetic circuit around the signal conductors are respectively provided to the signal conductors of the 6-pin cable. As a result, crosstalk between the signal conductors in a common mode is inhibited.
