Description

Technical Field

[0001] This utility model relates to the field of data cable technology, specifically a high-speed data transmission cable with double insulation and a filled structure. Background Technology

[0002] As the communication demands of high-speed interconnected data centers continue to evolve, the requirements for signal processing, bandwidth, and transmission density are increasing daily. Today, cloud data centers handle approximately 5 trillion gigabytes of data traffic annually, and with the development of 5G, IoT, and connected vehicles, the future data traffic will be enormous. To meet this rapidly growing bandwidth demand, higher signal transmission speeds, greater bandwidth, and stronger interconnect density are required. This presents a significant challenge to data center interconnect solutions.

[0003] like Figure 3 Traditional parallel-pair high-speed cables consist of two separate PE or PP foam-insulated cores, covered with an outer PE or PP inner sheath, plus metal tape shielding and self-adhesive polyester tape wrapping. Ordinary foamed PE or PP has low foaming degree, high dielectric constant, and large conductor volume. The binding of the outer aluminum foil and PET is not strong, resulting in an unstable physical structure, especially under static and dynamic bending conditions. This causes changes in the transmitted high-frequency signal (deterioration in attenuation, deterioration in differential signal to common-mode signal conversion), thus limiting the cable's transmission rate. High binding tension of the tape can cause deformation of the insulated cores, further degrading the transmitted high-frequency signal; ordinary insulation (… Figure 3 It has small pores that are not easy to distribute randomly in the insulator, has high production energy, and its structure is relatively unstable.
