Description

technical field [0001] The invention relates to high-speed data transmission, in particular to a differential signal cable. Background technique [0002] With the development of IoT, LTE / LTE-A / 5G communication technology, the growth of personal computers, cloud storage, cloud computing, servers, and supercomputers, high-speed digital signals that can transmit data faster than ever before are required 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. However, due to expensive transceivers and power consumption of optical modules, passive copper cables capable of high-speed data transmission are still required for short distances. [0003] In products such as servers, routers, and storage devices that process high-speed d...
