Problems solved by technology

However, as the industry expands to harsh environments such as deep seas and plateaus, existing optical cables often cannot meet industrial needs
For example, under the harsh tropical marine environment, the structure and performance of the sheath and other materials of the optical cable will be seriously affected, and it is easy to age Breakage will cause the optical fiber to be exposed, thereby destroying the stability of information transmission and causing huge economic losses; solar radiation, temperature and humidity have the greatest impact on the aging of optical cables, and they will cause the rubber material on the outer surface to become hard and brittle due to loss of elasticity

Abstract

The invention relates to an ultra-high weather-resistant optical cable. The ultra-high weather-resistant optical cable is sequentially composed of an optical fiber, an insulating layer, a waterproof layer, a flame-retardant layer, an anti-erosion layer, and an outer sheath from the inside to the outside; wherein, the outer sheath is composed of It is composed of thermoplastic polyurethane elastomer, nickel-chromium alloy and polyamide, and the mass ratio of thermoplastic polyurethane elastomer, nickel-chromium alloy and polyamide in the outer sheath is 10:2-3:5-6. The invention makes full use of the weather resistance, flame retardancy and water resistance of the optical cable by rationally arranging the structure of the optical cable from the inside to the outside, and generally improves the application effect of the optical cable. Maximize the weather resistance of the optical cable, so that the optical cable can be used in harsh or even harsh environments.

Description

technical field [0001] The invention relates to an optical cable, in particular to an ultra-high weather resistance optical cable. Background technique [0002] With the great development of the information society in the 21st century, the flow of information in various fields of our lives is increasing continuously, showing a development trend of a big explosion, which makes the high-speed communication and large-capacity possible, and lays the foundation for the construction of the information superhighway. a good foundation. At present, the application of optical fiber communication has been widely used in submarine communication, long-distance main line, cable TV, local area network and other fields. [0003] Optical cables are the most common materials in the field of information and communication, and their weather resistance or erosion resistance often determines the stability of optical fiber information transmission systems. However, as the industry expands to har...
