Abstract

The invention discloses an optical cable applicable to severe environments. According to the optical cable, an aluminium-clad steel stranded wire is used as a self-supporting suspension wire of the optical cable so as to effectively solve a problem that a self-supporting suspension wire is partially affected with damp to be rusted and broken; a stainless steel band armored structure is adopted tolongitudinally wrap a cable core part so as to effectively solve problems of side pressure resistance, damp resistance and rat biting resistance of the optical cable; by extruding a low-smoke zero-halogen polyolefin material on an outer surface of the aluminium-clad steel stranded wire and the anchored cable core, problems of solarization ageing and fire and flame retardance of the optical cable are effectively solved; when an optical cable main body is an optical unit, transmission of an optical signal can be implemented; when the optical cable main body is a feeder line unit, transmission ofpower can be implemented; and when the optical cable main body is an optic-electric hybrid unit, simultaneous transmission of the optical and electric signals can be implemented; and the optical cable is applicable to various severe environments.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an optical cable suitable for harsh environments. Background technique [0002] With the gradual emergence of the government's policy of stimulating domestic demand and the improvement of the economic situation, the market demand for optical cable installation in mountains and wastelands has expanded, and the market for optical cables suitable for these harsh environments has also expanded steadily. Due to the harsh construction and use environment of optical cables in high mountains and wastelands, traditional optical cables are prone to problems such as moisture, hanging wire corrosion, rat bites, aging in the sun, and poor fire and flame retardant effects, which seriously affect the safety of optical cable installation and increase operating costs. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the present invention pro...
