a fiber optic cable

Abstract

The invention discloses an optical cable. The optical cable comprises an optical cable core part and a detachable anti-ant assembly; the optical cable core part comprises a cross skeleton, optical fibre bundles and a flame retardant layer; the optical fibre bundles are positioned at four sides of the cross skeleton; the flame retardant layer is positioned on the surface layer; the detachable anti-ant assembly comprises four long strip-shaped anti-ant units; a male plug and a female plug matched with the male plug are respectively arranged at two sides of the anti-ant unit; at least one pair ofconnection heads are arranged on the male plug; a waterproof hot melt glue layer, a heat resistant layer and a nylon sleeve are respectively arranged between the male plug and the female plug from inside to outside; an anti-ant capsule is fixed in the heat resistant layer; anti-ant solution is arranged in the anti-ant capsule; an electric heating wire is arranged in the waterproof hot melt glue layer; and two ends of the electric heating wire are connected onto a pair of connection heads of the male plug. According to the optical cable in the invention, physical ant prevention and chemical ant prevention are combined; the time of duration is long (for above ten years); the anti-ant effect is good; when breaking the nylon sleeve by biting, white ants can touch an anti-ant drug; and thus, the white ants can be effectively expelled.

Description

technical field [0001] The invention relates to the field of optical cable production, in particular to an optical cable. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way and is covered with a sheath to realize optical signal transmission; a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of an optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are components such as a waterproof layer, a buffer layer, and an insulated metal wire as required. [0003] Existing o...
