High-speed data communication paired cable of the present utility model has cross-talk, electrostatic interference and the error rate between 6 important unit for electrical property parameters: Zu Kang ﹑ Shuai Jian ﹑ return losses, the interior cross-talk/group of group, has taken into full account six equilibrium in the time of design.
Impedance is parameter the most basic in electric property, and it determines apart from these three parameters of ﹑ insulative dielectric constant by the heart in conductor wire diameter ﹑ two conductors, any impedance do not mate the error that all can cause final acknowledge(ment) signal.We have taken into full account the impact of these three factors in the time of design, and conductor wire diameter is large, and low cut can be got well, but cost rising, final wire diameter is bigger than normal; The little decay of conductor wire diameter meeting is influenced.Considering while production the different and tension force of pitch, inconsistent can to produce each line different and affect impedance on two conductor centre-to-centre spacing, go out different insulation wire diameters according to different multiple twin pitch design, after guarantee finished product, the right resistance value of every line is controlled at 100 ± 15 Ohm left and right.
Decay is divided into conductor decay and diectric attenuation two parts, and conductor decay is relevant with resistance, so we adopt oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Insulating material is selected high density polyethylene (HDPE) (HDPE) or physical blowing polyethylene (FOAM PE) material, is all the smaller material of dielectric constant and dielectric loss angle.
Return loss is subject to the impact of input impedance, due to load impedance do not mate or make in the inhomogeneous point in cycle, and the reflection that produces signal, input impedance is fluctuateed up and down at characteristic impedance value, the energy of reflection aggravates along with the increase of frequency, even can produce the significantly sudden change of return loss.In design, adopt the pre-back twist technology of pair twist, eliminated the periodically impact of inconsistent generation on input impedance, improved the stability of input impedance, thereby optimized return loss.
When cross-talk designs in group, used the statistical method of Six Sigma experimental design to select best pitch, thereby met the requirement of crosstalking in group, real system can meet the qualified index of crosstalking of different levels.
