Description
Technical field
The present invention relates to light transmission communications carrier technical field, particularly a kind of butterfly optical cable with skeleton.
Background technology
Along with the fast development of telecommunications industry, people are more and more higher to the demand of bandwidth, the inside and outside numerous and confused mode that adopts optical fiber to insert in native land; For this reason, People's Republic of China's communications industry has been formulated standard YD/T 1997-2009 " Access Network butterfly leading in cable "; Country has also worked out GB/T 13993.4 " communications optical cable series the 4th part: Access Network outdoor optical cable ".Roughly all stipulated in these two standards to insert and used butterfly optical cable, made regulation for the size of getting rid of the outer cable body of messenger wire, followed according to needs, the optical fiber in the optical cable can adopt the optical fiber or the fibre ribbon of dispersion, to satisfy user's demand.This type optical fiber has brought a series of convenience to user and operator really.
Yet, regrettably: the optical cable of stipulating in the above-mentioned standard all is to adopt optical fiber or fibre ribbon to realize directly into the mode of sheath, there is following defective in this class optical cable: optical fiber directly contacts with sheath during 1, owing to production, and in the production run extrusion temperature of sheath more than 150 degrees centigrade, though the time that optical fiber contacts with sheath high temperature is not long, optical fiber still usually can heat damage; 2, because optical fiber or fibre ribbon in the optical cable are whole, therefore, when people only need a small amount of optical fiber, also optical cable all have to be opened stripping, isolate needed optical fiber so that continue, so, the great damage that optical cable itself just is subjected to has caused hidden danger for later maintenance.
Summary of the invention
In order to address the above problem, the invention provides a kind of butterfly optical cable with skeleton, it is to adopt following technical scheme to realize:
The butterfly optical cable of band skeleton is characterized in that: it comprises a skeleton 7, that is positioned at the optical cable center at least and is coated on the outer protective seam of skeleton 3, two and lays respectively at first reinforcement 1 of the relative both sides of skeleton, the restrictive coating 2 that an integral coating is lived skeleton, first reinforcement and protective seam; A plurality of skeleton grooves 4 are arranged on the skeleton, be placed with the optical fiber 9 or the fibre ribbon 5 of dispersion in the skeleton grooves; On arbitrary xsect, the center of the line at described two first reinforcement centers process skeleton and reinforcement center equate to the length of the line of frame center; Crossing frame center and a pair of tearing port 6 that is used for whole stripping fiber optic cables is being arranged with the other both sides of the perpendicular skeleton of the line at the first reinforcement center.
The butterfly optical cable of above-mentioned described band skeleton, its feature are that also the center of skeleton 7 has second reinforcement 8.
The butterfly optical cable of above-mentioned described band skeleton is characterized in that described skeleton grooves is 2～12; And symmetry or distribution asymmetricly on skeleton.

The butterfly optical cable of above-mentioned described band skeleton is characterized in that described protective seam is waterstop or nonwoven fabrics or polyester belt or glass fiber tape.
The butterfly optical cable of above-mentioned described band skeleton is characterized in that described protective seam is coated on outside the skeleton in the mode that vertical coating or winding coat; When vertically coating, overlapping width is 2～4mm; Twine when coating, overlapping width is 1～4mm.
The butterfly optical cable of above-mentioned described band skeleton is characterized in that described restrictive coating is low density polyethylene or medium density polyethylene or high density polyethylene or low smoke and zero halogen tygon or low-smoke low-halogen tygon or anti-electric trace tygon or nylon or Polyvinylchloride.
The butterfly optical cable of above-mentioned described band skeleton, the model that it is characterized in that described optical fiber 9 are G652 or G655 or G657 or A1a or A1b.
The butterfly optical cable of above-mentioned described band skeleton is characterized in that described fibre ribbon 5 is the fine band of 2 cores or the fine band of 4 cores or the fine band of 6 cores or the fine band of 8 cores or fine band of 10 cores or the fine band of 12 cores.
The butterfly optical cable of above-mentioned described band skeleton, its feature also are also to be placed with in the described skeleton grooves tear off element 10.
The butterfly optical cable of above-mentioned described band skeleton, its feature are that also described tear off element is aramid fiber rope or caprone cable or terylene rope.
Among the present invention, because optical fiber or fibre ribbon place in the skeleton grooves, therefore, in process, sheath does not contact with optical fiber, so the shortage of heat of sheath is to damage optical fiber; In addition because skeleton is coated with protective seam, therefore, optical fiber obtained effective protection more, and convenient for production; In addition,, therefore, can follow in the construction according to needs and open optical fiber or the fibre ribbon of shelling in the required groove, and not need whole stripping fiber optic cables because skeleton grooves separates, therefore quite little for the infringement of optical cable, the later maintenance of being more convenient for; Again and since skeleton in be provided with tear off element, therefore, optical cable open the stripping convenient.
Therefore, the present invention has following beneficial effect: properties of optical fiber cable is more reliable and more stable, production is more convenient, construction and safeguard easier.
