Abstract

A high-speed digital signal transmission cabinet comprises more than one differential signal cable, wherein each differential signal cable comprises an insulation core line, a shielding layer, a firststable layer or a sheath layer and a selectable drainage wire, the insulation core line comprises a pair of dual conductors, first insulation dielectric belts and an insulation stable layer, the pairof dual conductors are arranged in parallel, the first insulation dielectric belts respectively wrap the dual conductors, the insulation stable layer jointly wraps the first insulation dielectric belts, the material of each first insulation dielectric belt is a belt-shaped material having low density, low dielectric constant and low dielectric loss, and the first insulation dielectric belts are integrally and closely wrapped by the insulation stable layer. The high-speed digital signal transmission cabinet has the characteristics of small external diameter, light weight, small bending radius,more flexibility, low resilience, excellent temperature / mechanical stability, low loss and high cutoff frequency.

Description

technical field [0001] The invention relates to high-speed data transmission, in particular to a high-speed digital signal transmission cable. Background technique [0002] With the development of IoT, LTE / LTE-A, and 5G communication technology, the growth of personal computers, cloud storage, cloud computing, servers, and supercomputers requires high-speed digital signals that can transmit data faster than ever before. transmission cable. Optical fiber high-speed digital signal transmission cable provides the best data rate and performance for long-distance and high data rate transmission, because optical fiber high-speed digital signal transmission cable provides transmission with low attenuation and low bit error rate. Optical fiber high-speed digital signal transmission cables provide data transmission with a data rate up to or even exceeding 25Gb / s. However, due to expensive transceivers and power consumption of optical modules, passive copper cables capable of high-s...
