Abstract
The utility model discloses a fully dry type band-shaped indoor optical cable having 144 cores or less than 144 cores. The fully dry type band-shaped indoor optical cable is composed of an optical fiber band, a sleeve pipe, a reinforcing member and a sheath. The optical fiber band is intertwisted and then is directly sleeved in the sleeve pipe in a plastic manner. The high strength plastic is adopted as the plastic shielding material. A High strength synthetic fiber is adopted as the reinforcing member which is tightly and uniformly intertwisted around the sleeve pipe. Then, the sheath is extruded around the reinforcing member. The sleeve pipe is made from a special hard plastic which is fine in shaping after high temperature fusion. The optical cable is of a fully dry structure. No auxiliary material is filled in the sleeve pipe. A full medium material is adopted for the structure of the optical cable. Non-metallic materials are adopted for the part from a fiber in the core position to the sheath outside. Therefore, the optical cable is guaranteed to be superior in softness and enables the demand of wiring to be satisfied.
Description
Technical field
The utility model 144 cores and following core count that the dry type indoor ribbon optical cable relates to is the optical cable of last kilometer in a kind of Access Network that is applied to that Fiber to the home; Can directly process connector or welding mode; Realize terminal or switching quickly and easily, mainly use on house wiring or the machine room terminal device.
Background technology
Along with fiber-to-the-home arrival; The user is increasing to the demand of communication bandwidth; In the machine room circuit switched, also just need light friendship, the light of high capacity, big core number to set fully; Therefore sanitation and hygiene for the space of saving the machine room switching equipment better during with construction insert optical cable to tradition and propose more harsh requirement: constantly reduce cable outer diameter, adopt the dry type structure, reduction optical cable cost.Make a general survey of the optical cable of existing each structure at present, all be difficult to accomplish simultaneously above some.
Summary of the invention
The purpose of the utility model is to above-mentioned weak point; Provide 144 cores and following core to count the dry type indoor ribbon optical cable; Can solve an above difficult problem effectively, the optical cable of this structure not only has the advantage that external diameter is little, in light weight, cost is low; And adopt the structure of dry type, full medium, the choosing of the ideal of Access Network " last kilometer " wiring that is that Fiber to the home (FTTH).
The realization technical scheme of the utility model is: 144 cores and following core are counted the dry type indoor ribbon optical cable, it is characterized in that, fibre ribbon is not filled through not adopting ointment after stranded, and directly cover is moulded big sleeve pipe, and the cover moulding material adopts the special high-strength plastics; Adopt high strength synthetic fibre as reinforcement, be stranded in around the big sleeve pipe closely, equably; Around reinforcement material, extrude sheath at last.
144 above-mentioned cores and following dry type indoor ribbon optical cable is characterized in that: said shell material is extraordinary rigid plastics, and the high-temperature fusion postforming is good; Cable configuration adopts the dry type structure, does not fill any auxiliary material in the sleeve pipe; Cable configuration all adopts full dielectric material, and the sheath from the optical fiber at core position to the outside all is nonmetallic materials, guarantees that optical cable has superior softness, and it is required to satisfy wiring.
It is reasonable that 144 cores of the present invention and following core are counted the global design of dry type indoor ribbon optical cable, compact conformation, and the manufacture craft flow process is reliable.144 cores and the following dry type indoor ribbon optical cable made through the present invention have following characteristics:
1. structure is little, the core number is big, and it is high to hold fine density, reduces the wiring requisite space effectively;
2. dry type structure, sanitation and hygiene during construction realize the purpose of fast rapid-result end;
3. do not contain any metal material in the optical cable, having superior flexibility can;
4. adopt the flame-proof environmental protection material, satisfy the demand of user's house wiring.
Description of drawings
Fig. 1 is that the utility model 144 cores and following core are counted dry type indoor ribbon optical cable cross-sectional structure synoptic diagram.
Embodiment
Below will combine accompanying drawing that the utility model is described further.
Fig. 1 is that said 144 cores of the utility model and following core are counted dry type indoor ribbon optical cable cross-sectional structure synoptic diagram.
With reference to accompanying drawing 1, fibre ribbon 1 places in the sleeve pipe 2, and even outside sleeve pipe 2, tight stranded high strength aramid fiber 3 extrudes one deck sheath 4 outside aramid fiber 3.
144 cores of present embodiment and following core are counted the dry type indoor ribbon optical cable and are taked following scheme to realize:
One, fibre ribbon stacks up with the folded mould of being with according to sequence number by adopting helical twist cage with certain tension force with pitch is stranded releases in order; Extraordinary rigid plastics are molten condition after heating through machine barrel high temperature, extrude through specific extrusion die, through the bosh cooling and shaping; Optical fiber combination after the stack is passed the mould of extruder through guid needle, and the sleeve pipe after typing is stretched to traction, regulates certain force of strain take-up one-tenth dish.
Two, with the sleeve pipe unwrapping wire; The high strength aramid fiber evenly, closely be stranded in sleeve pipe around; On the aramid fiber stranded layer, extrude sheath, get into the cold water cooling, after going up through the Tension Control measuring system, coil in the take-up to the production line traction through caliper.
Though the present invention with preferred embodiment openly as above; But embodiment and accompanying drawing are not to be used for limiting the present invention, anyly have the knack of this art, in spirit that does not break away from the present invention and scope; Can do various variations or retouching from working as, all within protection scope of the present invention.What therefore protection scope of the present invention should be defined with the application's claim protection domain is as the criterion.
Claims (2)
1. a core and following core are counted the banded inside cable of dry type, it is characterized in that it is made up of fibre ribbon, sleeve pipe, reinforcement and sheath, and said fibre ribbon directly overlaps through stranded back to be moulded in said sleeve pipe, and the cover moulding material adopts the highstrenghtpiston; Adopt high strength synthetic fibre as said reinforcement, be stranded in around the said sleeve pipe closely, equably; Around said reinforcement, extrude said sheath at last.
2. the banded inside cable of dry type according to claim 1, it is characterized in that: the material of said sleeve pipe is extraordinary rigid plastics, and the high-temperature fusion postforming is good; Cable configuration adopts the dry type structure, does not fill any auxiliary material in the sleeve pipe; Cable configuration adopts full dielectric material, and the sheath from the optical fiber at core position to the outside all is nonmetallic materials, guarantees that optical cable has superior softness, and it is required to satisfy wiring.
