SFP+ high-frequency high-speed data transmission cable and manufacturing method therefor

Abstract

The invention relates to the technical field of scientific instruments, in particular to an SFP+ high-frequency high-speed data transmission cable and a manufacturing method therefor. The SFP+ high-frequency high-speed data transmission cable comprises an SFP+ cable signal wire, a ground wire, reinforced supporting layers, a low-dielectric-constant insulation layer and a shielding layer. The SFP+ high-frequency high-speed data transmission cable is a flexible flat cable. The reinforced supporting layer, the SFP+ cable signal wire, the reinforced supporting layer, the low-dielectric-constant insulation layer and the shielding layer are designed on two sides of the ground wire in sequence. According to the flexible flat cable design of the SFP+ high-frequency high-speed data transmission cable, the combination of the signal wire, the ground wire, the low-dielectric-constant insulation layer and the shielding layer can be finished in one time, and the hidden trouble of bad properties caused by own factors of all similar devices such as a twisting device, an extrusion device and a shielding-wrapping device can be avoided; and due to the flexible flat cable design of the SFP+ high-frequency high-speed data transmission cable, the cable is flexible and can be bent on the horizontal plane at will, and the cable can be bent to any angle by bending radius of more than 2mm.

Description

technical field [0001] The invention relates to the technical field of SFP+ high-frequency and high-speed data transmission cables, in particular to SFP+ high-frequency and high-speed data transmission cables and a manufacturing method thereof. Background technique [0002] At present, the SFP+ high-frequency and high-speed data transmission cables on the market are all designed with round wires, which have the following disadvantages: [0003] 1. High-frequency high-speed data transmission cable round wire design The cable needs to go through complex processes such as conductor stranding, signal wire extrusion, signal wire stranding, signal wire shielding wrapping, overall stranding, and sheath extrusion. Very strict quality control is required to ensure the stability of high-frequency attenuation, echo loss, and crosstalk characteristics of finished cables. The multi-process quality control of round wire design for high-frequency and high-speed data transmission cables is ...
