Problems solved by technology
Due to the longitudinal wrapping structure, there is no external force to fix the aluminum foil after it is formed, so the aluminum foil has a force release after forming, which makes the sealing of the aluminum foil easy to open. When the signal frequency reaches above 1GHz, the wavelength is already quite short. As a result, the joint gap of the shielding layer of the longitudinal package structure is enough for signal waves above 1 GHz to pass through, resulting in signal leakage and signal distortion. From the structural design, it cannot meet the transmission of satellite signals with a bandwidth of 2.15 GHz

Abstract
The invention relates to a multi-rate transmissionsatellite signal cable. The cable comprises a plurality of data lines which are arranged in parallel and have different rates, a sheath is coated outside the plurality of data lines, and each data line comprises at least one group of twisted pairs; in the data line formed by multiple groups of twisted pair wires, each group of twisted pair wires is provided with a first shielding layer, and the multiple groups of twisted pair wires are mutually twisted; and a double-layer shielding layer is also arranged in the data line formed by the group of twisted pair wires. The invention relates to a symmetrical cable for shielding a signal transmission line pair, and belongs to the technical field of electronic information. A plurality of groups of data lines with different rates are arranged in parallel, so that the cable meets various transmission requirements, the satellite signal data line and the Ethernet data signal line are arranged together, and the cost can be saved; and in addition, shielding structures are arranged on the data lines with the different rates, so the overall transmission performance is improved, and complete transmission of signals is ensured.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a satellite signal cable for multi-rate transmission. Background technique [0002] At present, there are relatively mature high-speed signal data transmission lines on the market, such as U / FTP CAT6A data lines. The data line adopts a wire pair shielding structure of 4 pairs of 8 cores. The wire pair shielding method is vertical wrapping, but this structural design is suitable for products below 1GHz. Due to the longitudinal wrapping structure, there is no external force to fix the aluminum foil after it is formed, so the aluminum foil has a force release after forming, which makes the sealing of the aluminum foil easy to open. When the signal frequency reaches above 1GHz, the wavelength is already quite short. As a result, the joint gap of the shielding layer of the longitudinal package structure is enough for signal waves above 1 GHz to pass through, resulting in signal leaka...
