Abstract
The invention relates to a self-supporting high-fiber-count butterfly lead-in optical cable, which comprises an optical fiber loose tube which is arranged in the center of the optical cable and a jacket which is extruded on the periphery of the optical fiber loose tube, wherein reinforced members which are arranged on two sides of the optical fiber loose tube are arranged inside the jacket, the reinforced members are symmetrically arranged on the left side and the right side of the optical fiber loose tube, the reinforced members are parallel to an optical cable reinforced supporting wire, and the jacket is wrapped in an extruding way to form the cable. The self-supporting high-fiber-count butterfly lead-in optical cable has advantages that the self-supporting high-fiber-count butterfly lead-in optical cable is suitable for the indoor and outdoor lead-in application in the field with large span, light and simple in structure and is convenient to construct; a half-dry structure is adopted, so that convenience in construction is achieved, and the environmental protection can be favored; after a product is machined into a loose tube, the outer jacket is formed in one step, so that the machining process is simple, the rate of finished product is high; and due to the adoption of the loose-tube optical-fiber unit, the protection of the optical fibers in the construction of the optical cable can be greatly improved.
Description
Technical field
The present invention relates to a kind of optical cable, relate in particular to the big core of a kind of self-bearing type and count the butterfly leading in cable.
Background technology
Fiber to the home at present outdoorly connects optical cable to chamber structure of an essay dead band and is meant from shaft tower to the optical cable the user house; The main model of optical cable is GJYX (F) DCH type, and it has following shortcoming in construction, use:, the fibre ribbon processing characteristics is unstable; Smooth master is inhomogeneous for fibre ribbon; The outside dimension of optical cable is big, and quality is heavy, is not easy to construction, lays; Light unit fibre ribbon directly contacts with oversheath, fiber unit and damaged by external force; The inconvenience that continues of opening stripping and optical fiber of optical cable is unfavorable for construction, and fibre junction efficient is low; Light unit fibre ribbon directly contacts with oversheath, be prone to produce passage between fibre ribbon and sheath, effective waterproof, and then influence the normal use and the serviceable life thereof of optical cable.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of simple in structure, and the big core of the self-bearing type that safety coefficient is high is counted the butterfly leading in cable.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: the big core of this self-bearing type is counted the butterfly leading in cable; Comprise the optical fiber loose tube that is positioned at the optical cable center and extrusion molding sheath in the optical fiber loose tube outside; Be provided with the reinforcement that is positioned at the optical fiber loose tube both sides in the said sheath, said reinforcement is symmetricly set on the left and right sides of optical fiber loose tube, and said reinforcement is parallel with optical cable reinforcement messenger wire to extrude sheath composition cable through extruding the sheath mode.
Compared with prior art, usefulness of the present invention is: the big core of this self-bearing type is counted the butterfly leading in cable and is adopted the self-bearing type structure, and the following indoor and outdoor of carrying out that can be suitable for the bigger occasion of span is introduced use, and structure is light, is convenient to construction; Adopt the half dry type structure, be convenient to construction, help protecting environment; Product is processed into Song Taohou, the oversheath one-shot forming, and processing technology is simple, and yield rate is high, owing to adopted loose casing fiber optic unit, has improved in the optical cable construction protection to optical fiber widely.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is that the big core of self-bearing type of the present invention is counted butterfly leading in cable structural representation.
Among the figure: 1, optical fiber loose tube; 2, reinforcement; 3, optical cable is strengthened messenger wire; 4, sheath.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
The big core of a kind of self-bearing type shown in Figure 1 is counted the butterfly leading in cable; Comprise the optical fiber loose tube 1 and the sheath 4 of extrusion molding that are positioned at the optical cable center in optical fiber loose tube 1 outside; Be provided with the reinforcement 2 that is positioned at optical fiber loose tube 1 both sides in the said sheath 4; Said reinforcement 2 is symmetricly set on the left and right sides of optical fiber loose tube 1, and said reinforcement 2 and optical cable strengthen that messenger wire 3 is parallel to extrude sheath 4 and form cables through extruding sheath 4 modes, and said optical fiber loose tube 1 is the discrete type optical fiber loose tube.
The big core of this self-bearing type is counted the butterfly leading in cable and is adopted the self-bearing type structure, and the following indoor and outdoor of carrying out that can be suitable for the bigger occasion of span is introduced use, and structure is light, is convenient to construction; Adopt the half dry type structure, be convenient to construction, help protecting environment; Product is processed into Song Taohou, the oversheath one-shot forming, and processing technology is simple, and yield rate is high, owing to adopted loose casing fiber optic unit, has improved in the optical cable construction protection to optical fiber widely.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (1)
1. the big core of self-bearing type is counted the butterfly leading in cable; It is characterized in that: comprise the optical fiber loose tube (1) that is positioned at the optical cable center and extrusion molding sheath (4) in optical fiber loose tube (1) outside; Be provided with the reinforcement (2) that is positioned at optical fiber loose tube (1) both sides in the said sheath (4); Said reinforcement (2) is symmetricly set on the left and right sides of optical fiber loose tube (1), and said reinforcement (2) is parallel with optical cable reinforcement messenger wire (3) to extrude sheath (4) composition cable through extruding sheath (4) mode.
