Description

Technical Field

[0001] This utility model relates to the technical field of transmission cables, and in particular to a high-speed DP80 transmission line. Background Technology

[0002] Traditional DP80 transmission cables have the following drawbacks: 1. They have an internal ground wire in the high-speed pair, making manufacturing complicated and costly; 2. Their length is limited; beyond 1.2 meters, signal interference affects transmission performance; 3. The twisted-pair design restricts signal transmission, resulting in poor performance; 4. The use of HDPE insulation material for the signal pairs further limits signal transmission. A utility model patent with patent number CN212434276U, entitled "Double-Shielded High-Speed ​​Transmission Cable," discloses a double-shielded high-speed transmission cable including parallel wire pairs, a first shielding strip, and a second shielding strip. The first shielding strip covers the parallel wire pairs to the outside, and the second shielding strip covers the first shielding strip, effectively enhancing shielding and reducing signal loss. However, this transmission cable has a limited number of signal pairs, which cannot meet current signal transmission requirements. Utility Model Content

Each power line is located between two adjacent sets of high-speed pairs.

[0006] In some embodiments, the high-speed pair includes two parallel high-speed lines and a high-speed pair centering sheath, which is wrapped around the outside of the two parallel high-speed lines, and a gap of 0.075 mm is provided between the two high-speed lines.
