A circuit board coupled with jacks and conformed to Category 6 standard has conductors to connect IDC contacts and jack pins to reduce cross-talk and improve return-loss. The improvements are targeted on the pair 1 and 3 conductors of circuit conductors, and include forming capacitors by main conductors connecting to the IDC and jack on two sides of the circuit board, extending pair 1 and 3 conductor ends in the vicinity of IDC junctures to form a TR (or TT,RR) conductor layout, and extending pair 1 and 3 conductor ends in the vicinity of jack junctures to form a TT or RR conductor layout (or TT for IDC end, or RR for jack end) to generate induction effect, thereby to form the circuit board coupled with jacks that has circuit conductors laid on two sides thereof and conforms to Category 6 communication standard.
