Description

Novel foaming insulation high-speed data transmission's data cable

Technical Field

The utility model relates to the technical field of data cables, in particular to a novel foaming insulation high-speed data transmission data cable.

Background

As the communication demands of high-speed interconnected data centers continue to change, the demands for rapidly changing signal processing, bandwidth, and transmission density, etc., for data centers are increasing. Today's cloud data center needs to handle about 5 terabytes of data traffic each year, and in addition to the development of 5G, internet of things, internet of vehicles, etc., the data traffic that needs to be handled in the future will be very huge. To meet this rapidly growing bandwidth demand, there is a need to match higher signal transmission speeds, greater bandwidth and greater interconnect density. This presents a serious challenge for data center interconnect solutions.

As shown in fig. 4, the conventional "parallel pair" high-speed cable is formed by wrapping two independent PE or PP foam insulating core wires, wrapping a PE or PP inner sheath outside, and wrapping a metal tape shielding and self-adhesive polyester tape, and the common foamed PE or PP has low foaming degree, large dielectric constant, large conductor cable volume, and weak binding of the outer aluminum foil and the PET, so that the physical structure is not very stable, and particularly under the conditions of static bending and dynamic bending, the transmitted high-frequency signal can be changed (attenuation becomes worse, and differential signal to common mode signal becomes worse), thereby limiting the transmission rate of the cable. The large binding tension of the tape can lead to the deformation of the insulating core wire, thereby influencing the deterioration of the transmitted high-frequency signal; the common foamed insulator (figure 4) has small pores which are not small and not easy to be distributed in the insulator at will, and has high production energy and relatively unstable structure.
