Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] This embodiment is a dedicated 100 ohm symmetrical transmission cable for VDSL equipment, see figure 1 , The transmission cable is composed of a cabling layer, a shielding layer and a sheath.

[0022] The cabling layer is composed of 24 pairs of wires, which are divided into three layers and arranged in order. The arrangement is arranged in the order of different colors of the cores. The cabling structure is 2+8+14. The inner cores are wrapped with PP foam film during the cabling process. 25. The outside of the cabling layer is wrapped with PP film 25, the shielding layer is made of double-sided aluminum composite tape 27, a 0.41 tinned ground wire 26 is placed vertically in the middle, and the sheath is made of an environmentally friendly low-smoke halogen-free sheath 29. On the sheath Set with tear line 28.

[0023] The cables are 24 twisted ...

Abstract

The invention belongs to signal transmission technical field, relating to a signal transmission cable which comprises a cabling layer, a shielding layer and a jacket. The cabling layer comprises two or more twisted line pairs and each twisted line pair is coated with an insulating macromolecular frothing film; an insulating macromolecular frothing film is wound and coated on the cabling layer; and the twisted line pairs are distinguished by different colors. The cable provided by the invention is of stable structure, reliable performance and compact volume and is low in fabrication cost.

Description

technical field [0001] The invention belongs to the technical field of signal transmission and relates to a signal transmission cable. Background of the invention [0002] With the rapid development and progress of the telecommunications field, a large number of electronic and communication equipment are used, and they are increasingly sophisticated, complex and multi-functional, and all kinds of electronic equipment are always troubled by the unstable quality of signal transmission cables. Since the current transmission cables use high-tech manufacturing and other technologies, the cable structure and electrical quality are the most serious in terms of a system. It can not only properly handle internal signal transmission, but also completely transmit the internal signals of the system to the system. external. Therefore, equipment transmission cables play an extremely important role in transmission. Due to the bulky size and poor performance of the cables used for digital...
