Some fiber units and the water blocking yarn being wrapped on fiber unit, the position of the correspondence cable core is additionally provided with tear in sheath
Rope.
Further, the Loose tube is that dry type blocks water Loose tube.
Further, the reinforcer is two FRP bracing pieces being arranged symmetrically centered on cable core axial line.
Further, the tear rope is made of water resistance aramid fiber silk.
Further, at least two water blocking yarns are wound with the outside of each fiber unit.
Further, the fiber unit includes even number root silica fibre.
Further, the minimum wall thickness (MINI W.) of the sheath is 0.6mm.
Relative to prior art, the invention has the advantage that：
This optical cable is in integrally the structure of flat, is very suitable for access network engineering and uses, improves close with metope
Degree, it is convenient to be brought to construction.Meanwhile, this fiber optic cable manufacture cost is light, without scrap build, only need to process corresponding moulds of industrial equipment just
It can produce, whole optical cable has the advantages that lightweight, small volume, lightning protection, anti-electric shock without any metal material.

Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of nonmetallic dry type platypelloid type fire-retardant cable, as shown in figure 1, including cable core 1 and being coated on flat outside cable core 1
Flat-shaped sheath 2, provided with the reinforcer 3 being arranged symmetrically centered on the cable core 1 in sheath 2；The cable core 1 includes pine and covered
Some fiber units 5 inside pipe 4, Loose tube 4 and the water blocking yarn 6 being wrapped on fiber unit 5, the correspondence institute in sheath 2
The position for stating cable core is additionally provided with tear rope 7.
Above-mentioned Loose tube 4 is that dry type blocks water Loose tube.Loose tube 4 is PBT Loose tubes, due to using loose noose
Structure, optical fiber is in relaxed state in Loose tube, effective and reasonable remaining length can be obtained, with good optics, mechanical performance.
Can be as needed, non-metallic armoring layer is set on the outside of Loose tube, the mechanical performance of cable core, external force resistance impact is further enhanced
Ability is strong, is hardly damaged.
Above-mentioned reinforcer 3 is two FRP bracing pieces being arranged symmetrically centered on the cable core axial line, is effectively protected
Cable core, improves the overall mechanical strength of optical cable, and tension, anti-pressure ability are all strengthened, and are difficult during laying and use
Damage.
Above-mentioned tear rope 7 is made of water resistance aramid fiber silk, by tear rope can convenient stripping sheath, can play
The advantages of effect blocks water, is easy to construct, improving efficiency of construction.
Wherein, each outside of the fiber unit 5 is wound with least two water blocking yarns 6, and block-water performance is good.Above-mentioned optical fiber list
Member includes even number root silica fibre, and signal stabilization is reliable.Optical cable is blocked water using dry type, and wiping ointment can be reduced to construction
Required material and operating expenses, it is to avoid the pollution that ointment is caused during construction and use in pipe.
The minimum wall thickness (MINI W.) of above-mentioned sheath 2 is 0.6mm.It is >=3mm that the both sides of sheath 2, which are used to accommodate the wall thickness of the position of reinforcer 3,.
It is pointed out that sheath is preferred to use low-smoke non-halogen flame-retardant structure, with good fire resistance, the safe, feature of environmental protection
It is good, it is especially suitable for family's wiring and uses.In addition, sheath is in integrally platypelloid type structure, can convenient construction, and effectively raise
With the compactness of metope after construction.
This optical cable Productive statistics cost is light, without scrap build, and only need to process corresponding moulds of industrial equipment can just produce, whole
Optical cable uses all dielectric nonmetallic materials and outward appearance is flat form without any metal material, with lightweight, small volume, prevents
The advantages of thunder, anti-electric shock.In addition, using dry type structure, block-water performance is good, it effectively prevent during construction and use because passing
System greasy for preventing water on cable is wiped, the environmental pollution that drip is caused.Loose tube is using loose set technique, and pipe is interior to be held with larger optical fiber
The amount of receiving, the advantages of optical fiber is in relaxed state, optical fiber attenuation small excellent optical performance, cable jacket uses low-smoke non-halogen flame-retardant
Material, with good fire resistance, it is adaptable to access network and house wiring.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
