Abstract

The utility model 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

The large core of self-bearing type is counted the butterfly leading in cable
Technical field
The utility model relates to a kind of optical cable, relates in particular to the large core of a kind of self-bearing type and counts 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 refers to from shaft tower to the optical cable the user house, the main model of optical cable is GJYX (F) DCH type, it has following shortcoming in construction, use procedure:, the fibre ribbon processing characteristics is unstable, smooth master is inhomogeneous for fibre ribbon, the outside dimension of optical cable is large, 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, easily produces passage between fibre ribbon and sheath, effective waterproof, and then affect normal use and the serviceable life thereof of optical cable.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, and the large 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 utility model is achieved through the following technical solutions: the large core of this self-bearing type is counted the butterfly leading in cable, comprise that the optical fiber loose tube that is positioned at the optical cable center and extrusion molding are at the sheath of optical fiber loose tube outside, be provided with the reinforcement that is positioned at the optical fiber loose tube both sides in described sheath, described reinforcement is symmetricly set on the left and right sides of optical fiber loose tube, and described reinforcement is parallel with optical cable reinforcement messenger wire extrudes sheath composition cable by extruding the sheath mode.
Compared with prior art, usefulness of the present utility model is: the large core of this self-bearing type is counted the butterfly leading in cable and is adopted the self-bearing type structure, can be suitable for the larger occasion of span under carry out indoor and outdoor and introduce and use, structure is light, constructability; Adopt the half dry type structure, constructability is conducive to protection of the environment; Product is processed into Song Taohou, the oversheath one-shot forming, and processing technology is simple, and yield rate is high, owing to having adopted loose casing fiber optic unit, has improved widely in the optical cable construction protection to optical fiber.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is that the large core of the utility model self-bearing type is counted butterfly leading in cable structural representation.
In figure: 1, optical fiber loose tube; 2, reinforcement; 3, optical cable is strengthened messenger wire; 4, sheath.
Embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
The large core of a kind of self-bearing type shown in Figure 1 is counted the butterfly leading in cable, comprise that the optical fiber loose tube 1 that is positioned at the optical cable center and extrusion molding are at the sheath 4 of optical fiber loose tube 1 outside, be provided with the reinforcement 2 that is positioned at optical fiber loose tube 1 both sides in described sheath 4, described reinforcement 2 is symmetricly set on the left and right sides of optical fiber loose tube 1, described reinforcement 2 is parallel with optical cable reinforcement messenger wire 3 extrudes sheath 4 composition cables by extruding sheath 4 modes, and described optical fiber loose tube 1 is the discrete type optical fiber loose tube.
The large core of this self-bearing type is counted the butterfly leading in cable and is adopted the self-bearing type structure, can be suitable for the larger occasion of span under carry out indoor and outdoor and introduce and use, structure is light, constructability; Adopt the half dry type structure, constructability is conducive to protection of the environment; Product is processed into Song Taohou, the oversheath one-shot forming, and processing technology is simple, and yield rate is high, owing to having adopted loose casing fiber optic unit, has improved widely in the optical cable construction protection to optical fiber.
It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
