Abstract

The invention relates to an efficient flame retardant long-service-life optical cable, which sequentially comprises an outermost sheath, a shielding layer, a flame-retardant layer, an innermost protective layer and a cable core in order from outside to inside, wherein the outermost sheath is a mixture of polyvinyl chloride and insect repellent, the shielding layer is a compound of organosiloxane resin and an AZO nanoparticles, the innermost protective layer is a compound of polystyrene and silicon dioxide nanoparticles, and the cable core comprises a plurality of fiber bundle tubes and a reinforcing member arranged in the middle of the plurality of fiber bundle tubes. Through optimizing the compositions of the flame-retardant layer and the outermost sheath, the efficient flame retardant long-service-life optical cable greatly improves the fire-retardant and flame-retardant effect and insect prevention effect of the optical cable. The manufactured optical cable satisfies the requirementof high flame retardancy and adapts to various extreme environments.

Description

technical field [0001] The invention relates to an optical cable, in particular to an efficient flame-retardant and long-life 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] CN201810030598.7 provides a sensing optical cable for monitoring cracks in engineering structures. The main body is in the shape of a flat ribbon, with a built-in sensing unit, no reinforcing elements and an unarmoured outer sheath. The optical fiber at ...
