Description
Technical field
The present invention relates to the optical fiber technology field, relate in particular to a kind of fibre bundle and manufacturing approach thereof.
Background technology
Along with the fast development of communications industry, network demand increases day by day, and the requirement of big core being counted optical cable is also more and more.But fibre ribbon generally can only be made 12 cores, and the optical fiber of 12 different colours is arranged side by side and formed fibre ribbon as shown in Figure 1 through the UV resin solidification.If fiber number surpasses 12 cores, in the same fibre ribbon homochromy optical fiber will appear, bad resolution.So the core number of fibre ribbon is limited by the restriction of optical fiber color, for obtaining the optical cable of bigger core number, though also can the multifiber band be consolidated into integrally formed fibre bundle through the UV resin solidification.But because limits of color also can only be accomplished 12 cores basically; But also be faced with the bad problem of fissility; Considering when optical cable connects and must optical fiber wherein peeled off out one by one, all be that fibre ribbon is divided the formula placement so the big core of the use in the present optical cable is counted optical cable, like Fig. 2.But because receive the eye mask structural limitations, the fibre ribbon that the formula of dividing is placed can only have two, and this makes the contained fiber number of fibre bundle receive restriction greatly.If fibre ribbon is made the structure that nappe type is placed, can increase the fiber number in the fibre bundle greatly, peel off problem of difficult but bring thus.In fact, it is just more bothersome that the optical fiber ablation in the fibre ribbon shown in Figure 1 is come out, if fibre ribbon is the placement of nappe type, adjacent fibre ribbon adhesion area is bigger, peels off then more difficulty.So practical big core optical-fiber beam can not be introduced to the market always.
Summary of the invention
The object of the invention is to solve the deficiency with above-mentioned prior art, and the UV fibre bundle and the manufacturing approach thereof that a kind of big core number are provided and have been easy to peel off are specifically realized by following technical scheme:
A kind of UV fibre bundle comprises some fibre ribbons, and each fibre ribbon is provided with separation layer along the belt length outside surface, and said some fibre ribbons that are provided with separation layer stack to be placed and be integral by the UV resin bonded.
Its further design of described UV fibre bundle is: said optical fiber has 2 ~ 12, stacks into 2 ~ 12 layers.
Described UV fibre bundle further design is: said fibre ribbon is a cladded type.
Described UV fibre bundle further design is: it is the fibre bundle of circle or rectangle that the said some fibre ribbons that stack placement become the cross section by the UV resin bonded; Said cross section is 3000 ~ 3050 μ m for circular its diameter of fibre bundle, and said cross section is that the length of side on its long limit of fibre bundle of rectangle is 2150 ~ 2200 μ m.
Described UV fibre bundle further design is: said fibre bundle contains 2～8 and stacks fibre ribbon arranged side by side, and every fibre ribbon contains 8 optical fiber that tiling is arranged side by side.
Described UV fibre bundle further design is: said fibre diameter is 230 ~ 240 μ m.
The manufacturing approach of said fibre bundle comprises the steps:
1) some fibre ribbons that stack arrangement by levels are coated with liquid bath with the separation layer of certain speed through respective layer, make each fibre ribbon along applying separation layer on the outside surface of belt length;
2) all fibre ribbons carry out resin-coated with said speed through fibre bundle moulding eye mould, cool off after solidifying through the UV lamp again, form fibre bundle.
Described fibre bundle manufacturing approach further design is: UV lamp illumination was 4000 ~ 5500W when fibre ribbon solidified, and the UV lamp illumination when fibre bundle solidifies is 4500～6000W.
Described fibre bundle manufacturing approach further design is: said certain speed is 145～155m/min, and pressure is 2.0 ~ 1.7bar.
Described fibre bundle manufacturing approach, it further designs and is: the flow of resin is 70～90ml/min in the fibre bundle moulding eye mould.
The present invention stacks placement arranged side by side with fibre ribbon and makes fibre bundle, and making it contained core number increases greatly, and applies separation layer through the appearance at fibre ribbon; Like silicone oil, solve the bonding problem of fibre ribbon adjacent fiber band and fibre ribbon and resin, the higher temperature when utilizing the UV lamp to solidify makes the separation layer gasification substance; Make between adjacent fiber band and fibre ribbon and the resin and do not have adhesion; Thereby fibre ribbon in the fibre bundle is peeled off become very convenient, the present invention has overcome the technological prejudice that the fibre ribbon of thinking in the prior art in the fibre bundle can not stack placement arranged side by side, has realized that people are to counting the demand of optical cable to big core; Processing technology is simple simultaneously, and the steady quality of processing.
