Abstract
An indoor and outdoor dual-purpose optical cable comprises a cable core and a sheath wrapping the periphery of the cable core. A reinforcing layer and a dry waterproof layer are successively arranged between the cable core and the sheath from inside to outside, and the sheath consists of a flame-retardant inner sheath and an outer sheath wrapping the outer side of the flame-retardant inner sheath. As the optical cable comprises the dry waterproof layer, the flame-retardant inner sheath, the outer sheath and the reinforcing layer, the optical cable has better waterproof performance and flame resistance, can resist outdoor low temperature and ultraviolet radiation, can be applied to both indoor and outdoor environments, can be conveniently bent for wiring, and reduces troubles in optical cable laying and usage.
Description
Technical field
The present invention relates to the dual-purpose optical cable in a kind of indoor and outdoor.
Background technology
In the prior art, Access Network feeder line optical cable is divided into outdoor optical cable and inside cable.During use, be abutted against head between the two and connect, comparatively trouble.And outdoor, indoor varying environment is also different to the performance requirement of optical cable, and outdoor optical cable requires outdoor low temperature of ability and ultraviolet radiation, and has water preventing ability preferably, and inside cable requires to have anti-flammability preferably, and both can not be general.Thereby, for reducing the trouble in optical cable laying and the use, need a kind ofly can be applied to the optical cable that outdoor environment can be applied to indoor environment again.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can be applied to the dual-purpose optical cable that outdoor environment can be applied to indoor environment again.
For achieving the above object, the technical solution used in the present invention is:
The dual-purpose optical cable in a kind of indoor and outdoor comprises cable core, is coated on the sheath of described cable core periphery, is disposed with enhancement Layer, dry type water blocking layer between described cable core and the described sheath from inside to outside; Described sheath comprises fire-retardant inner sheath, is coated on the oversheath of described fire-retardant inner sheath periphery.
Preferably, described enhancement Layer is the aramid fiber enhancement Layer.
Preferably, described dry type water blocking layer is a water blocking yarn, and described water blocking yarn is provided with the imbibition powder.
Preferably, be provided with aluminium strip between described fire-retardant inner sheath and the described oversheath.
Preferably, described oversheath is made by PVC.
Preferably, described fire-retardant inner sheath is made by halogen-free low-smoke flame retardant material.
Preferably, the described optical cable in described fire-retardant inner sheath upper edge axially is provided with and tears rope.
Preferably, described cable core is a kind of in tight tube fiber or the loose tube fiber.
Preferably, described cable core comprises loose sleeve pipe, is positioned at the stranded optical fiber of described loose sleeve pipe, is filled with fine cream in the described loose sleeve pipe.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
Because the present invention is provided with dry type water blocking layer, fire-retardant inner sheath, oversheath, enhancement Layer, make optical cable have water preventing ability, anti-flammability preferably simultaneously, and outdoor low temperature of ability and ultraviolet radiation, outdoor environment can be applied to and indoor environment can be applied to again, and be convenient to crooked wiring, reduced the trouble in optical cable laying and the use.
Description of drawings
Accompanying drawing 1 is the schematic cross-section of the dual-purpose optical cable in indoor and outdoor of the present invention.
In the above accompanying drawing: 1, loose sleeve pipe; 2, optical fiber; 3, fine cream; 4, fire-retardant inner sheath; 5, oversheath; 6, tear rope; 7, aluminium strip; 8, aramid fiber enhancement Layer; 9, water blocking yarn.
Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described:
Embodiment one: shown in accompanying drawing 1.
The dual-purpose optical cable in a kind of indoor and outdoor comprises cable core, is coated on the sheath of cable core periphery;
Cable core comprises loose sleeve pipe 1, is positioned at the stranded optical fiber 2 of loose sleeve pipe 1, is filled with fine cream 3 in the loose sleeve pipe 1;
Sheath comprise by halogen-free low-smoke flame retardant material make fire-retardant inner sheath 4, be coated on the oversheath of making by PVC 5 of fire-retardant inner sheath 4 peripheries, fire-retardant inner sheath 4 upper edge optical cables axially are provided with tears rope 6; Be provided with aluminium strip 7 between fire-retardant inner sheath 4 and the oversheath 5;
The dry type water blocking layer that is disposed with aramid fiber enhancement Layer 8 between cable core and the sheath from inside to outside, forms by water blocking yarn 9 and imbibition powder placed thereon.
But be arranged at the imbibition powder imbibition on the water blocking yarn 9, make the dry type water blocking layer play resistance effect; Fire-retardant inner sheath 4 can play fire retardation; Aramid fiber enhancement Layer 8 can make optical cable have certain intensity; Oversheath can anti-outdoor low temperature and ultraviolet radiation; Aluminium strip 7 can play the reinforcement protective effect.Whole optical cable can use in outdoor environment, use tear rope 6 oversheath 5 and aluminium strip 7 peelled off after, optical cable can be in indoor use.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
