Communication cable transmission parameters include:
1. The effective resistance: the effective resistance of the cable circuit including dc resistance and the additional resistance through alternating current (ac).
2. Inductance: in a communication cable circuit, the ratio of the flux cause a current of the magnetic flux called inductance.
3. Capacitor: cable circuit of the capacitance capacitor concept is similar to that of a general capacitor, the surface of the conductor is equivalent to a capacitor plate, and wire insulation between the equivalent dielectric capacitor. Its value is conductors of electricity and the ratio of two conductors of potential difference.
4. Insulation conductance: insulation conductance said a circuit insulation quality. Insulation conductance is generally divided into two parts, the dc and ac conductivity conductance, the former is caused by the insulation of the cable medium not perfect, and the latter is caused due to the effect of polarization of the medium. Insulation conductance to medium heat, resulting in energy loss.
