Abstract
The utility model relates to a tight coating optical fiber used for indoor optical cables and the stern cables of various apparatuses and devices, which comprises optical fiber and a coating layer which is coated outside the optical fiber. The utility model is characterized in that a separating layer is arranged between the optical fiber and the coating layer and has the advantages of a separating layer having excellent inadhesion property and lubricating property is arranged between the optical fiber and the coating layer causing the coating layer to easily strip the optical fiber; the longest length of once stripped coating layer can reach 25 mm to 200 mm bringing convenience for using; the stress condition of the optical fiber in the coating layer further reducing the stress of the optical fiber for enhancing the transmission characteristic of the optical fiber; the utility model has the advantages of simple structure and easy fabrication and realization.
Description
Technical field
The utility model relates to a kind of tight tube fiber of easily peeling off that is used for inside cable, various instrument and equipment stern fast.
Background technology
In inside cable and various instrument, communication facilities stern fast, tight tube fiber is set mostly.Existing tight tube fiber coats the coating that one deck is made up of padded coaming outward by optical fiber and constitutes, because coating and optical fiber are in conjunction with tight, when optic fibre end connected, coating was difficult for being stripped from, and this not only gives the actual quilt stripping section of making troubles but also can damage optical fiber when peeling off of using.On the other hand, the coating of tight cover also can produce certain stress influence to optical fiber.
Summary of the invention
Technical problem to be solved in the utility model is will overcome the deficiency that prior art exists and provide a kind of its coating to be easy to peel off, and uses, connects tight tube fiber easily.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include optical fiber and be coated on the outer coating 5 of optical fiber, its difference is to be provided with a separating layer 4 between optical fiber and coating.
The beneficial effects of the utility model are: 1, the not separating layer of viscosity and lubricity of tool excellence is set between optical fiber and coating, makes coating be easy to peel off optical fiber, the longest 25～200mm that reaches of the coating that once separates has brought convenience to use; 2, improve the force-bearing situation of optical fiber in coating, the suffered stress of optical fiber is further reduced, thereby strengthened the transport property of optical fiber; 3, simple in structure, be easy to make and realize.
Description of drawings
Fig. 1 is layer structural drawing that cut open of an embodiment of the utility model.
Embodiment
Further introduce embodiment of the present utility model below in conjunction with accompanying drawing, include optical fiber, optical fiber is by fiber core 1, fibre cladding 2 and optical fiber coating 3 constitute, be coated with a separating layer 4 at optical fiber, separating layer is made of the filling glue (Lunrctra WA840) that with the synthetic oil is matrix, or be that the dispersed lubricant (DryFilm RA) of Main Ingredients and Appearance constitutes by fluo-copolymer PTFE with teflon, separating layer thickness is 3～6 μ m, in addition, separating layer also can be made of the matrix material (Cablelite3287-9-41) that a kind of UV fast (ultraviolet ray) solidifies, thickness is 20～130 μ m, therefore this elasticity modulus of materials can make above-mentioned two-layer being easy to be stripped from much smaller than the elastic modulus of optical fiber coating and coating; Be coated with coating 5 in separating layer 4, constitute thus and easily peel off tight tube fiber.
Claims (4)
1, a kind of tight tube fiber of easily peeling off includes optical fiber and is coated on the outer coating (5) of optical fiber, it is characterized in that being provided with between optical fiber and coating the separating layer (4) of the sticking and greasy property of tool.
2,, it is characterized in that optical fiber is made of fiber core (1), fibre cladding (2) and optical fiber coating (3) by the described tight tube fiber of easily peeling off of claim 1.
3, by claim 1 or the 2 described tight tube fibers of easily peeling off, it is characterized in that separating layer (4) is made of the filling glue that with the synthetic oil is matrix, or be that the dispersed lubricant of Main Ingredients and Appearance constitutes by the fluo-copolymer PTFE with teflon, separating layer thickness is 3～6 μ m.
4, by claim 1 or the 2 described tight tube fibers of easily peeling off, it is characterized in that separating layer (4) is made of the matrix material of UV curing fast, thickness is 20～130 μ m.
