Description

A kind of optical fiber ribbon cable
Technical field
The invention belongs to technical field of basic electronic devices, especially relate to the improvement of a kind of optical fiber ribbon cable.
Background technology
Arrival along with the information age. the construction of communication network just from before with optical cable be prevailing transmission medium backbone network construction turn to the Metropolitan Area Network (MAN) with optical cable for prevailing transmission medium and access network construction. to meet users' wilderness demand to the multimedia broadband services such as voice, image.This needs large core number, small size, high density, is easy to fast splicing, is easy to the optical cable of maintenance.Optical fibre band optical cable (hereinafter referred to as optical fiber ribbon cable) is the optimum selection meeting the demand, optical fiber ribbon cable with multiple simple optical fibers by painted, be stacked into band and optical cable that the fibre ribbon of secondary coating is processed into for unit.Optical fiber is with two kinds, i.e. the viscous type of lock-in type and limit, the former can bear transverse pressure, the latter's thinner thickness.Often can there be 4,8,12 or 16 optical fiber in band.Band inner fiber spacing is 0.28mm(for 4,8) and 0.3mm(for 12 and 16), proper alignment, vertical direction has flatness, i.e. irrelevance requirement, cannot be greater than such as 30,40,50um(determines according to band inner fiber number), in order to cluster (welding) continues.Band inner fiber uses chromatograph in an orderly manner, and when being beneficial to maintenance and continue, recognition is errorless.Fibre ribbon volume is little, can improve the collection dress density of optical fibre in optical cable, may make up core number very big, such as 320 until 3456 cores.Suitable in the rapid Optical Access Network of current development.But, existing optical fiber ribbon cable also has some shortcomings, and such as waterproof effect is poor, the problem of poor toughness.
Summary of the invention
The present invention is aiming at the problems referred to above, it is provided that a kind of optical fiber ribbon cable of a kind of good water-proof effect and good toughness.
For realizing the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme that, a kind of optical fiber ribbon cable, including fibre core and restrictive coating, it is characterized in that: in restrictive coating, be provided with the fibre core of more than three, described fibre core includes the optical fiber loose tube outside fibre ribbon and fibre ribbon, and described fibre ribbon is made up of several glass optical fibers, and described glass optical fiber diameter is between 125um to 140um;Being provided with center reinforcement in restrictive coating center, fibre core is arranged around center reinforcement, and described center reinforcement is anticorrosive steel strand;It is provided with gasket for packing between adjacent fibre core;Described restrictive coating includes the interior waterstop of innermost layer, and interior waterstop is outside around being surrounded by aluminium strip, and aluminium strip is provided externally with outer waterstop, and extrernal resistance hose jacket is oversheath.
As a kind of preferred version, described oversheath is PE oversheath.
As another kind of preferred version, several glass optical fiber spirals of described composition fibre ribbon twist together;Make structure more stable.
As another preferred version, being provided with clad at fibre ribbon outer layer, what described clad was loose is coated on fibre ribbon outer layer, and protection band structure of optic fibre consolidates further.
Beneficial effects of the present invention.
The present invention is provided with center reinforcement and effectively raises the tensile energy of optical cable, reduces the stretching of optical cable, effectively the optical fiber in protection optical cable.Optical fiber without strained tensile entirely by forming the remaining length in the glass optical fiber restrictive coating of fibre ribbon, therefore the present invention adopts Loose tube, makes the range of activity of fibre ribbon more greatly, increase service life and toughness.And the present invention is provided with inside and outside two-layer water blocking layer, the seepage problem occurred when solving buried optical cable.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, is used for together with embodiments of the present invention explaining the present invention, is not intended that limitation of the present invention.
Fig. 1 is present configuration schematic diagram.
In figure, 1, for oversheath, 2 be outer water blocking layer, 3 be aluminium strip, 4 be interior water blocking layer, 5 be optical fiber loose tube, 6 be fibre ribbon, 7 be clad, 8 be gasket for packing, reinforcement centered by 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of optical fiber ribbon cable, including fibre core and restrictive coating, it is characterized in that: in restrictive coating, be provided with the fibre core of more than three, described fibre core includes the optical fiber loose tube 5 outside fibre ribbon 6 and fibre ribbon 6, described fibre ribbon 6 is made up of several glass optical fibers, and described glass optical fiber diameter is between 125um to 140um;Being provided with center reinforcement 9 in restrictive coating center, fibre core is arranged around center reinforcement 9, and described center reinforcement 9 is anticorrosive steel strand, is provided with gasket for packing 8 between adjacent fibre core;Described restrictive coating includes the interior waterstop 4 of innermost layer, and interior waterstop 4 is outside around being surrounded by aluminium strip 3, and aluminium strip 3 is provided externally with outer waterstop 2, and extrernal resistance hose jacket 2 is oversheath 1.
Described oversheath 1 is PE oversheath.
Several glass optical fiber spirals of described composition fibre ribbon 6 twist together;Make structure more stable.
Being provided with clad 7 at fibre ribbon outer layer, what described clad 7 was loose is coated on fibre ribbon outer layer, and protection band structure of optic fibre consolidates further.
The present invention is provided with center reinforcement and effectively raises the tensile energy of optical cable, reduces the stretching of optical cable, effectively the optical fiber in protection optical cable.Optical fiber without strained tensile entirely by forming the remaining length in the glass optical fiber restrictive coating of fibre ribbon, therefore the present invention adopts Loose tube, makes the range of activity of fibre ribbon more greatly, increase service life and toughness.And the present invention is provided with inside and outside two-layer water blocking layer, the seepage problem occurred when solving buried optical cable.
