Problems solved by technology

However, since the addition of a colorant (pigment) increases the permittivity, and the permittivity differs depending on the color of the added colorant
Therefore, the permittivity will vary depending on the color combination of the paired insulated wires, and therefore, the signal propagation time will vary greatly

Abstract

A twinax cable includes at least a pair of core wires, each of which includes a conductor and an insulator covering an outer periphery of the conductor. The insulator includes an inner insulator covering the outer periphery of the conductor and an outer insulator covering an outer periphery of the inner insulator. The inner insulator is formed by a non-colored compressed insulator. The outer insulator is formed by a colored compressed insulator. A thickness of the outer insulator is formed thinner than a thickness of the inner insulator. The outer insulators of the pair of core wires are formed to have hues that are set respectively differently.

Description

technical field [0001] The present disclosure relates to a twinax cable accommodated in an HDMI (High Definition Multimedia Interface) cable for transmitting video and sound signals and for a differential signaling system. Background technique [0002] A low voltage differential signaling (LVDS) system is known as a system for transmitting digital signals by using a pair of twinax cables using a pair of insulated signal conductors. In this signal system, for example, at the transmitting end, signals whose phases are reversed by 180 degrees are simultaneously input to a pair of signal conductors and transmitted, and at the receiving end, the transmitted signals are differentially combined to double the signal output . The signaling system is equipped with a noise canceling function. Specifically, noise signals generated in a transmission line extending from a transmission end to a reception end are applied equally to the pair of signal conductors so that they cancel each ot...
