Abstract
The utility model relates to a full-dry multi-core air-blowing cable, which includes a nonmetal reinforcement piece positioned at the center, a plurality of optical fiber bundles stranded and arranged on the nonmetal reinforcement piece, a nonmetal tensile element coating the periphery of the optical fiber bundles in a winding or longitudinal manner, and a polyethylene jacket formed on the periphery of the nonmetal tensile element through extrusion molding. The optical fiber bundles are subjected to secondary coating and lighting for solidification, and have stronger flexibility. The prepared optical fiber bundles are directly stranded to form the cable, so that the optical fiber cores of the cable are greatly increased; the whole cable is not required to be filled with jelly, and the whole has a full-dry structure, thereby avoiding pollution to the environment during construction; and the cable has higher popularization and application values.
Description
Technical field
The utility model relates to a kind of communications optical cable, relates in particular to a kind of optical cable that pipeline lays that is suitable for being blown into.
Background technology
In the fiber cable laying process of Metropolitan Area Network (MAN),, can not go again roughing-in again to be used for the transmission of light signal because conduit resource lays.Simultaneously, be limited to the constraint of existing conduit resource, human resources, require on the one hand the outside dimension of optical cable should be as much as possible little, require the core number of optical fiber should be many as much as possible on the other hand, to satisfy the needs of signal transmission.
Existing air-blowing optical cable mostly is the central beam tube type structure, as shown in Figure 1, its center is a multifiber 11, optical fiber is arranged in the loose sleeve pipe 12, and between loose sleeve pipe 12 and optical fiber 11, be filled with fine cream 13, the periphery of pine sleeve pipe 12 is coated with aramid yarn and PE sheath successively, and its fiber number of this kind air-blowing optical cable can only be accomplished can't satisfy the requirement of big core number below 24 cores.And optical cable contains the fine cream of liquid, causes the pollution to environment during construction easily.
Summary of the invention
The utility model purpose provides that a kind of external diameter is less, fiber number is more and whole optical cable is the air-blowing optical cable of dry type.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of dry type multicore is counted the air-blowing optical cable, it comprises the non-metal reinforcement member that is positioned at the center, stranded the pe sheath that is arranged on a plurality of fibre bundles on the described non-metal reinforcement member, the wrapped or vertical nonmetal tensile elements that wraps in the fibre bundle periphery and extrusion molding in the tensile elements periphery, and each described fibre bundle is by the multifiber curing molding.
Further, also be provided with many water blocking yarns between a plurality of fibre bundles.
Described tensile elements is an aramid yarn.
Described fibre bundle is 2～10.
Each described fibre bundle comprises 2～24 optical fiber.
Owing to adopt technique scheme, the utlity model has following advantage:, make the fiber number of optical cable increase considerably, and whole optical cable does not need factice for filling by the direct stranded stranding of a plurality of fibre bundles that will make, integral body is the dry type structure, the environmental pollution when having avoided construction.This dry type multicore is counted the air-blowing optical cable and has been solved the excessive crowded problem of pipeline that causes of cable outer diameter effectively, and it is fine convenient to divide, and cabling process adopts existing equipment to carry out, and therefore, has stronger application value.
Description of drawings
Accompanying drawing 1 is existing air-blowing optical cable viewgraph of cross-section;
Accompanying drawing 2 is that the utility model dry type multicore is counted air-blowing optical cable viewgraph of cross-section;
Wherein: 1, non-metal reinforcement member 2, fibre bundle 21, optical fiber 3, tensile elements 4, sheath; 5, water blocking yarn 11, optical fiber 12, loose sleeve pipe 13, ointment 14, aramid yarn 15, sheath;
Embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the utility model is described:
Dry type multicore is as shown in Figure 2 counted the air-blowing optical cable, it comprises a plurality of fibre bundles 1, is positioned at the non-metal reinforcement member 2 at center, wrapped in fibre bundle 1 periphery nonmetal tensile elements 3 and extrusion molding at the pe sheath 4 of tensile elements 3 peripheries.Wherein, formula is stranded in the shape of a spiral is arranged on the non-metal reinforcement member 2 for a plurality of fibre bundles 1, and nonmetal tensile elements 3 selects for use aramid yarn to realize.
Between fibre bundle 1, also be provided with water blocking yarn 5, enter in the cable core to stop moisture content.
In the present embodiment, fibre bundle 1 is 6, and each fibre bundle 1 is formed by 21 curing of 12 optical fiber, certainly, the fibre bundle of the utility model air-blowing optical cable is not limited to 6, and the optical fiber radical of each fibre bundle also is not limited to 12, will the job operation of fibre bundle be introduced below:
At first, 2～24 optical fiber are carried out even tension control through guide wheels after, export in the mould that fills resin, in mould, optical fiber is finished an internal layer coating, the optical fiber after will applying then is cured under ultraviolet illumination.Optical fiber after will solidifying again carries out the secondary resin and applies outward, and is same, carries out illumination curing once more, thereby form a fibre bundle.Applying once and adopt the low modulus resin, is about 1mpa as modulus, and it forms the fibre bundle cushion, thereby improves the bending resistance of fibre bundle.External coating adopts high modulus resin, is about 700mpa as modulus, makes the fibre bundle of moulding have certain rigidity and intensity, further protects optical fiber.
Fibre bundle after making adopts existing optical cable manufacturing process to carry out the processing of the utility model air-blowing optical cable, be specially fibre bundle stranded stranding on non-metal reinforcement member, it is wrapped wrapped with water blocking yarn to carry out aramid yarn then, and last extrusion molding layer of polyethylene material forms oversheath.
The utility model air-blowing optical cable adopts optical fiber curing to become the direct stranding of mode of fibre bundle, make that the external diameter of whole optical cable is less, and fiber number is more, the pipeline that has laid there is wideer applicability, can effectively utilize the conduit resource of having completed and carry out fiber cable laying, it can directly utilize in the optical cable production existing equipment to produce, and production technology is easy, the product percent of pass height satisfies the needs that following optical cable develops.
