Description
Technical field
The utility model is related to communications optical cable technical field, especially a kind of novel optical fiber band flat indoor optical cable.
Background technology
Using optical fiber as the fiber optic communication of the transmission medium of light, why can in decades be obtained rapidly at this
Development, is since it has（1）Transmission frequency bandwidth, message capacity are big；（2）Decay small；（3）Not by electromagnetic interference outstanding advantages of
And determine, but light itself is fragile, and the low defect of mechanical strength requires it that must be set with protection shell composition in outer layer
Optical cable, to provide mechanical protection for it, to protecting the basic demand of shell to be：Ensure light during manufacture, laying, use
Fine not broken and suffered stress is small；The transmission performance that must keep optical fiber original in the fabrication process, and ensure that optical fiber exists
Transmission performance is reliable and stable during long-time service.
Inside cable structure usually used at present is relatively simple, by single-core fiber and is coated on single tight tube fiber surface
Restrictive coating constitute, the production technology of this inside cable is relatively simple, but the mechanical performance of interior optical cable is poor, is using
It is easy to cause the bending or fracture of optical fiber in journey, the transmission of optical signal is caused to lose or interrupt.In addition, single-core fiber data transmission
Capacity is also smaller.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of novel optical fiber band flat room light
There is preferable mechanical performance and environmental performance, soft, flexible, connecting conveniently, Large Volume Data can be supported to pass for cable, the optical cable
It is defeated, it is suitable for optical communication equipment computer room, the light connects of Optical Distribution Frame and the light connects of light instrument, equipment.
The purpose of this utility model is achieved through the following technical solutions：
A kind of novel optical fiber band flat indoor optical cable includes fibre ribbon, casing layer, aramid yarn enhancement layer successively from the inside to the outside
And oversheath；Include successively from the inside to the outside equipped with several tight tube fibers being connected side by side, the tight tube fiber in the fibre ribbon
Bare fibre, coat and fixed coating；The cross section of described sleeve pipe layer and the oversheath is rectangular configuration.
In the present invention, the seamed edge of oversheath is arc seamed edge, and in mounting and installation, the seamed edge of arc will not be right
Surrounding articles or construction personnel cause to scratch.
In the present invention, fibre ribbon includes 2 cores, 4 cores, 6 cores, 8 cores or 12 core optic fibre belt optics, the bare fibre in fibre ribbon
Type includes the optical fiber of single mode G.652, G.655 or G.657 optical fiber, multimode A1a or A1b optical fiber or other models and type.
In the present invention, the oversheath is PVC oversheaths, LSZH oversheaths or TPU oversheaths, flame retardant effect
It is good, the mechanical and physical performance of oversheath meet in building in laying, optical communication equipment computer room laying, Optical Distribution Frame light
The light connects of connection and light instrument, equipment.
The utility model has the beneficial effects that：
（1）With preferable mechanical performance and environmental performance, soft, flexible, connecting conveniently, can support Large Volume Data to pass
It is defeated, it is suitable for optical communication equipment computer room, the light connects of Optical Distribution Frame and the light connects of light instrument, equipment；
（2）, the seamed edge of oversheath is arc seamed edge, in mounting and installation, the seamed edge of arc will not to surrounding articles or
Construction personnel causes to scratch.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 101- fibre ribbons, 102- casing layers, 103- aramid yarn enhancement layers, 104- oversheaths.
