Abstract
The invention discloses a home-entrance connected optical cable with high tensile strength. The optical cable comprises a glass optical fiber located in the center, a cladding wrapping an external portion of the glass optical fiber and a wear-resisting rubber protection sleeve located on an external portion of the cladding. The wear-resisting rubber protection sleeve comprises an optical fiber protection portion, an intermediate connection portion and a reinforcement steel wire protection portion. The optical fiber protection portion wraps the external portion of the cladding. A first waterproof layer, a shielding layer and a second waterproof layer are arranged between the optical fiber protection portion and the cladding. A twisting steel wire is arranged in the reinforcement steel wire protection portion. The twisting steel wire is formed through twisting 8-12 thin steel wires. Through the above mode, the structure of the optical cable is simple and reasonable; the high tensile strength and good wear-resisting performance are possessed; besides, good waterproof performance and shielding anti-interference performance are possessed too.
Description
Technical field
The present invention relates to optical cable technology field, particularly relate to the high house lead in of a kind of tensile strength and connect optical cable.
Background technology
Fiber optic network communication enters daily life, has the advantage that transfer rate is fast, eliminates old cable transmission gradually.Buildings in city is all just arranged optical cable in unit, room in building course, and people only need simply to open application after moving in, and just can use optical fiber communication.
At present, Fiber-optic Communication Projects has also started to spread to vast rural area, rural area is all the family little Yuan of house not sharing an entrance with others, optical fiber is drawn to need to connect house lead in optical fiber from the optical fiber stake in roadside, again house lead in optical fiber is moved to inside family, but all plant in the little institute of many families of rural area and expired various trees, these trees will be passed unavoidably when house lead in optical fiber is pulled upward to inside family from curbside optical fiber stake, when running into strong wind weather, branch waves and rocks, can scratch optical fiber unavoidably, this just requires that optical fiber has good tensile property, anti-wear performance, in addition when running into rainstorm weather, optical fiber is also needed to have good water resistance.
Summary of the invention
The technical matters that the present invention mainly solves is to provide the high house lead in of a kind of tensile strength and connects optical cable, simple and reasonable, has higher tensile strength and good anti-wear performance; Also there is good water resistance and shielding interference free performance in addition.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the house lead in providing a kind of tensile strength high connects optical cable, comprising: be positioned at the glass optical fiber at center, be coated on the covering of described glass optical fiber outside and be positioned at the abrasive rubber protective sleeve of covering outside;
Described abrasive rubber protective sleeve comprises fiber optic protection portion, middle interconnecting piece and reinforcement steel wire protection portion, and described fiber optic protection portion is coated on covering outside, also has the first water blocking layer, screen layer and the second water blocking layer between described fiber optic protection portion and covering;
Be provided with braided wires line in described reinforcement steel wire protection portion, described braided wires line forms by 8 ~ 12 finer wires are stranded.
In a preferred embodiment of the present invention, described first water blocking layer, screen layer and the second water blocking layer set gradually outward from interior.
In a preferred embodiment of the present invention, described braided wires line forms by 10 finer wires are stranded.
The invention has the beneficial effects as follows: the house lead in that tensile strength of the present invention is high connects optical cable, simple and reasonable, has higher tensile strength and good anti-wear performance; Also there is good water resistance and shielding interference free performance in addition.
