Abstract

The invention discloses a flame-retardant composite optical cable. The optical cable comprises a cable core and an outer sheath. The cable core comprises optical fiber assemblies and a loose tube. Theloose tube sleeves the optical fiber assemblies. Fiber paste is filled between the loose tube and the optical fiber assemblies. A fireproof layer assembly is arranged outside the cable core, the fireproof layer assembly comprises a first fireproof layer, a second fireproof layer and a third fireproof layer, the first fireproof layer is annularly arranged outside the loose sleeve, an armor layer is arranged outside the first fireproof layer, and the armor layer is arranged in the outer wall of the first fireproof layer in a surrounding mode. According to the invention, a mica tape wraps the cable core to serve as the first fireproof layer; the optical cable can be effectively prevented from cracking, the insulation effect can be achieved, the manufacturing cost is low, the effect is dual-purpose, the second fireproof layer and the third fireproof layer are CNTS reinforced silicon nitride ceramic layers respectively, the mechanical property of the optical cable can be improved on the basis of improving the high temperature resistance, and the optical cable is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a flame-retardant composite optical cable. Background technique [0002] An optical cable is a cable core composed of a certain number of optical fibers in a certain way, covered with a sheath, and some are also covered with an outer sheath, which is used to realize optical signal transmission. It is usually used in the field of communication, and is also applied to other high-tech fields such as sensing, measurement, control, and data acquisition, such as mining industry, aerospace industry, military, oil and gas, and high-temperature medical applications. These fields will involve some special application environments, such as high temperature environments. [0003] When the optical cable is used in an outdoor environment, its service life generally does not exceed 5 years. In places such as mountainous areas or densely populated cities, the replacement and maintenance ...
