Abstract
The utility model provides a butterfly pipeline cable for a longitudinal steel strip lapping reinforcer. The butterfly pipeline cable comprises a butterfly optical cable subunit, two reinforcers, a water-blocking tape, polyester yarns, an aluminum tape and a sheath, the butterfly optical cable subunit is arranged in the middle, the two reinforcers are placed on two sides of the butterfly optical cable subunit respectively, the water-blocking tape closely wraps the butterfly optical cable subunit and the reinforcers, the aluminum tape is longitudinally lapped outside the water-blocking tape, the polyester yarns are filled in the space between the aluminum tape and the water-blocking tape, and the outside of the aluminum tape is wrapped with the sheath. The butterfly pipeline cable has the advantages that the cable is low in optical fiber transmission loss and chromatic dispersion, small in outer diameter, light in weight and applicable to being laid in a pipeline inlet place, the cable is directly connected with an indoor optical cable through a connector after the tip of the cable is stripped off, mounting efficiency is greatly improved, and flexibility and bending resistance are excellent.
Description
Technical field
The utility model relates to a kind of butterfly cable, specifically a kind of pipeline butterfly cable.
Background technology
FTTH (Fiber To The Home) is as the term suggests be exactly that an optical fiber direct is received family.Specifically, FTTH refers to optical network unit (ONU) is installed in household user or enterprise customer place, be in the light access series except FTTD (fiber to the desk) the most close user's optical access network application type.The remarkable technical characterstic of FTTH is the bandwidth that not only provides larger, and has strengthened the transparency of network to data form, speed, wavelength and agreement, has relaxed requirements such as environmental baseline and power supplies, has simplified and has safeguarded and installation.
Along with the high speed development of FTTH, the butterfly optical cable that is suitable for the FTTP network is widely used.And pipeline butterfly cable is applicable to lay in pipeline, its fiber transmission attenuation of structures shape of existing pipeline butterfly cable is large, external diameter is little large, and heavier, and needs welding during construction when being connected with the city optical cable, operation inconvenience has reduced operating efficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of pipeline butterfly cable of the vertical bag of steel band reinforcement of new structure, and fiber transmission attenuation is little, external diameter is little, and connects fast.
The utility model solves the problems of the technologies described above by the following technical solutions: the pipeline butterfly cable of the vertical bag of a kind of steel band reinforcement, comprise butterfly optical cable subelement, reinforcement, waterstop, polyester yarn, aluminium strip, and sheath, described butterfly optical cable subelement places the centre position, 2 reinforcements are placed on respectively the both sides of butterfly optical cable subelement, waterstop is the described butterfly optical cable subelement of parcel, reinforcement closely, waterstop is tied up polyester yarn outward, polyester yarn is the described aluminium strip of vertical bag outward, at the described sheath of aluminium strip coated outside.
Further, the pipeline butterfly cable xsect of the vertical bag of described steel band reinforcement is rounded, is fit to install in indoor or the pipeline.
Further, described butterfly optical cable subelement comprises optical fiber, the strengthening core in the middle of being positioned at, and butterfly sheath, described strengthening core has two, lay respectively at longitudinally upper and lower of optical fiber, the butterfly sheath is bundled together optical fiber and strengthening core, and the both lateral sides central authorities of described butterfly sheath have respectively a groove, strengthens the pliability of pipeline butterfly cable.
The utility model has the advantage of: fiber transmission attenuation is little, dispersion is low, external diameter is little, lightweight, is applicable to the laying in pipeline entering place, directly is connected with the city optical cable by connector after the strip off of termination, improved greatly installation effectiveness, pliability and counter-bending ability are good.
Description of drawings
Fig. 1 is the structural drawing of the pipeline butterfly cable of the vertical bag of the utility model steel band reinforcement.
Embodiment
See also shown in Figure 1ly, the pipeline butterfly cable wrap of the vertical bag of the utility model steel band reinforcement is drawn together butterfly optical cable subelement 1, reinforcement 2, waterstop 3, polyester yarn 4, aluminium strip 5, and sheath 6.
Described butterfly optical cable subelement 1 places the centre position, 2 reinforcements 2 are placed on respectively the both sides of butterfly optical cable subelement 1, waterstop 3 is the described butterfly optical cable subelement 1 of parcel, reinforcement 2 closely, the waterstop 3 outer polyester yarns 4 of tying up, the described aluminium strip 5 of polyester yarn 4 outer vertical bags is at the described sheath 6 of aluminium strip 5 coated outside.
The pipeline butterfly cable of this structure is on the basis of proof strength, and external diameter is little, lightweight, and fiber transmission attenuation is little, dispersion is low.For the structure that makes cable keeps stable, used polyester yarn 4 further to tie up butterfly optical cable subelement 1 and reinforcement 2, the use of aluminium strip 5 has not only further strengthened the intensity of pipeline butterfly cable and can prevent bad cable of animal bites, the pipeline butterfly cable xsect of the vertical bag of described steel band reinforcement is rounded, is fit to install in indoor or the pipeline.
Described butterfly optical cable subelement 1 comprises optical fiber 12, the strengthening core 14 in the middle of being positioned at, and butterfly sheath 16.Described strengthening core 14 has two, lays respectively at longitudinally upper and lower of optical fiber 12, and butterfly sheath 16 is bundled together optical fiber 12 and strengthening core 14, and the both lateral sides central authorities of described butterfly sheath 16 have respectively a groove 162, strengthens the pliability of pipeline butterfly cable.Described strengthening core 14 adopts KFRP(aromatic polyamide fiber reinforced plastics optical cable strengthening core), the KFRP strengthening core not only has good meat pliability, and also has certain rigidity.Its apportion optical fiber 12 both sides when pipeline butterfly cable is crooked, can well protect optical fiber 12 not by curved disconnected.Pipeline butterfly cable not only can adopt mode of traction when cable installation in pipe, also can adopt the mode of sending into.
The above is only for the preferred embodiment of the invention; not in order to limit the invention; all in the invention spirit and principle within do any modification, be equal to and replace and improvement etc., all should be included within the protection domain of the invention.
