As a manufacturer of power cable, let me introduce you (4) Characteristic impedance Different from the loop DC resistance, the characteristic impedance includes resistance and inductance impedance and capacitance impedance of 1-100MHz, which is related to the distance between a pair of wires and the... read more
(1) Attenuation Attenuation is a measure of signal loss along the link. The attenuation is related to the length of the power cable. As the length increases, the signal attenuation also increases. The unit of attenuation is "db", which represents the ratio of the signal strength at the source transm... read more
