Ultrahigh-weatherability optical cable

Abstract

The invention relates to an ultrahigh-weatherability optical cable, which successively consists of a fiber, an insulating layer, a waterproof layer, a flame retardant layer, an anti-erosion layer andan oversheath from inside to outside. The oversheath is composed of a thermoplastic polyurethane elastomer, nickel chromium alloy and polyamide, and the mass ratio of the thermoplastic polyurethane elastomer, the nickel chromium alloy and the polyamide in the oversheath is 10:2-3:5-6. Through reasonable arrangement of the structure of the optical cable from inside to outside, weatherability, flameresistance and waterproofness of the optical cable are brought into full play and application effects of the optical cable are improved as a whole. Through cooperation of the oversheath and the anti-erosion layer, the weatherability of the optical cable is brought into play to the maximum, so that the optical cable can be applied to harsh and even severe 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...

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
