Abstract
The utility model discloses a central tube type optical fiber ribbon cable comprising an optical fiber ribbon. A central part is provided with the optical fiber ribbon which is sleeved by a PBT loose tube. Fiber paste is filled between the optical fiber ribbon and the PBT loose tube. The PBT loose tube is wrapped by a steel-plastic composite belt. A hot melt adhesive layer is arranged between the steel-plastic composite belt and the PBT loose tube. The steel-plastic composite belt is wrapped by a PE sheath. The optical fiber ribbon is formed by twisting 8 to 144 fibers. According to the utility model, through adding the steel-plastic composite belt in the PE sheath, through a hot melt adhesive bonded structure between the steel-plastic composite belt and loose tube, the cable has excellent mechanical performance and environmental performance, moisture proofing and water blocking effects of the cable are ensured, after laying the cable, no retraction of the loose tube is ensured, a core number of an optical fiber ribbon structure is high, and anti-pressure ability of a steel belt armored structure is excellent.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of central tubular optical fibre band optical cable.
Background technology:
Mostly the optical cable of existing fiber belt is that fibre ribbon is with sleeve pipe outward; And the structure of cooperation oversheath, its mechanical property is relatively poor, goes wrong easily when growing apart from backguy; Secondly cable outer sheath adopts the PE sheath usually; Its pressure-proof and snap-resistent ability is relatively poor, in case dug or bump by mistake by mistake, is easy to occur situation such as breakage, fracture.Therefore imagination provides a kind of new construction of establishing to solve this problem.
The utility model content:
The purpose of the utility model just provides a kind of central tubular optical fibre band optical cable, and mostly the optical cable that solves the existing fiber belt is that fibre ribbon is with sleeve pipe outward, and cooperates the structure of oversheath; Its mechanical property is relatively poor; Go wrong easily when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor; In case dug or bump by mistake, be easy to occur the problem of situation such as breakage, fracture by mistake.
The technical scheme that the utility model adopts is:
A kind of central tubular optical fibre band optical cable; Comprise fibre ribbon: central part has fibre ribbon; Fibre ribbon is set with PBT pine sleeve pipe outward, is filled with fine cream between fibre ribbon and the PBT pine sleeve pipe, and PBT pine sleeve pipe is wrapped with composite steel-plastic belt; Have hot melt adhesive layer between composite steel-plastic belt and the PBT pine sleeve pipe, composite steel-plastic belt is wrapped with the PE sheath.
Said fibre ribbon is stranded the forming of 8-144 root optical fiber.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through increasing composite steel-plastic belt in the PE sheath; The structure of hot melt adhesive bonding can make optical cable have good mechanical property and environmental performance between composite steel-plastic belt and the loose sleeve pipe, has not only guaranteed the moistureproof block-water effect of optical cable; And after having guaranteed fiber cable laying; The pine sleeve pipe does not have retraction, and its band structure of optic fibre core number is high, and the steel-tape armouring anti-pressure ability is good.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of central tubular optical fibre band optical cable; Comprise fibre ribbon: central part has fibre ribbon 1, and the fibre ribbon 1 outer PBT pine sleeve pipe 2 that is set with is filled with fine cream 3 between fibre ribbon 1 and the PBT pine sleeve pipe 2; PBT pine sleeve pipe 2 is wrapped with composite steel-plastic belt 4; Have hot melt adhesive layer 5 between composite steel-plastic belt 4 and the PBT pine sleeve pipe 2, composite steel-plastic belt 4 is wrapped with PE sheath 6, and fibre ribbon is stranded the forming of 8-144 root optical fiber.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection domain of the utility model.
