Abstract

The invention discloses a photoelectric composite data bus and a preparation method thereof. The photoelectric composite data bus comprises at least three silver-plated copper wire stranded conductorsand a single-mode optical fiber transmission carrier; the silver-plated copper wire stranded conductors are wrapped with a first insulating layer; the single-mode optical fiber transmission carrier is wrapped by a second insulating layer; the silver-plated copper wire stranded conductors are stranded in the peripheral direction of the single-mode optical fiber transmission carrier to form a photoelectric composite cable core; a fastening layer is disposed outside the photoelectric composite cable core in a wrapping manner; a shielding layer is arranged outside the fastening layer; an outer sheath is extruded outside the shielding layer, and the photoelectric composite data bus is obtained through the method of twisting the conductors, wrapping the insulating layer, forming the electric composite cable core, wrapping the fastening layer and the shielding layer, and extruding the outer sheath. According to the invention, the problems that photoelectric signals cannot be transmitted at the same time and are not resistant to high temperature and low temperature are solved, and the technical effects that the bus can transmit the photoelectric signals at the same time, can resist high and low temperatures of-65 DEG C to + 200 DEG C, and can meet the requirement for transmitting photoelectric multi-path signals in aerospace craft tasks and control systems are achieved.

Description

technical field [0001] The invention relates to the technical field of signal transmission cables for aerospace, in particular to a photoelectric composite data bus and a preparation method thereof. Background technique [0002] The photoelectric data bus is a high-speed serial bus and optical fiber channel transmission carrier. In the development process of my country's new stealth fighter, it will also use the photoelectric composite data bus communication interface to transmit complex, diverse and efficient video and image signals. ; Develop this type of photoelectric composite data bus, so that the photoelectric composite data bus can also meet other harsh military environments such as field operations and water surfaces within a wide temperature range. However, in the existing bus signal transmission, one is that the photoelectric signals cannot be transmitted in the same way at the same time, and the other is that the optical signals are not resistant to high temperatur...
