Technical field
The present invention relates to a kind of optical cable, specifically a kind of central tube type optical cable.
Background technology
Optical cable (optical fiber cable) be in order to meet optics, machinery or environment performance specification and manufacture
, it be by the use of one or more optical fiber being placed in cladding sheath as transmission medium and can use individually or in groups it is logical
Letter cable-assembly.Optical cable is mainly by optical fiber（The glass fiber of thin such as hair）With plastic protective sleeve pipe and plastic peel structure
Into, there is no the metals such as gold, silver, copper aluminium in optical cable, general non-recovery is worth.Optical cable is a number of optical fiber according to certain way
The composition cable heart, is surrounded by outward sheath, and the also cladding outer jacket having is used to realize a kind of communication line of optical signal transmission.I.e.：By
Optical fiber（Optical transmission carrier）The cable formed by certain technique.The basic structure of optical cable is usually by cable core, strengthens steel
Several parts compositions such as silk, filler and sheath, according further to needing the also component such as waterproof layer, cushion, insulated metal wire.
Existing optical cable is generally the internal circular optical cable comprising multifiber, Loose tube filled type structure, in order to increase
Pull resistance, inside filling aramid fiber or other metals, can apply to outdoor.
Present optical cable tensile effect is general, is easily damaged in wiring, and protective capability is not enough, causes optical cable to use
It is badly damaged, causes service life shorter, it is smaller using scope, it is impossible to meet present use requirement.
The content of the invention

To achieve the above object, the present invention provides following technical scheme：
A kind of central tube type optical cable, including center reinforcemen, center reinforcemen are arranged in fibre bundle, and fibre bundle sets inner sheath
Interior, inner sheath is arranged in tension set, and tension is set in fire-retardant set, and fire-retardant to be set in PBT pine sets, PBT pines are arranged
Put in waterproof jacket, waterproof is set in water blocking yarn, water blocking yarn is arranged in oversheath, oversheath is arranged on corrosion-resistant set
It is interior.
As further scheme of the invention：The oversheath is polyvinyl chloride oversheath.
As further scheme of the invention：Fire-retardant fine cream is filled with the fibre bundle.
As further scheme of the invention：Tensile steel wire is provided with the tension set.
As further scheme of the invention：The center reinforcemen is arranged in polyethylene jacket, and center reinforcemen is non-
Metal reinforcing fibre.
Compared with prior art, the beneficial effects of the invention are as follows：Structure of the present invention is novel, and easy to use, water proof fire retardant is resistance to
Corrosion, wide using scope, tensile capacity is strong, and long service life meets present use requirement.
