Description
[technical field]
The utility model relates to communication facilities technical field, specifically the peripheral reinforced simple and easy optical cable of a kind of dry type.
[background technology]
Fiber to the home, and cable configuration used is various, has self-bearing type 8 shaped optical cables, butterfly optical cable, central-beam tube type fiber optic cable, layer-stranding cable etc.According to current used situation, these optical cables all have some limitations, and such as external diameter is large, Heavy Weight, pulling force is little, fiber capacity is little, construction is inconvenient etc.And layer-stranding cable unit number generally more than Unit 5, and needs the center strengthening core of corresponding size as support, thereby physical dimension is large, and optical cable is from heavy, and ointment is filled, and lays loaded down with trivial details with installation procedure and environment is had a certain impact.Therefore, microminiaturization, lightness are by the developing direction of optical cable after being, especially fiber entering household roughing-in space is narrow, and to cable size, fiber capacity, combination property require high.And current existing technology is difficult to meet these requirements simultaneously.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of dry type peripheral reinforced simple and easy optical cable, both ensured that optical cable longitudinally blocked water comprehensively, construction environment is clean, and the glass fiber tape of different-thickness can make optical cable reach different pulling force, there is effect that anti-mouse to a certain degree bites.
Design for achieving the above object the peripheral reinforced simple and easy optical cable of a kind of dry type, comprise cable core and oversheath 9, between described cable core and oversheath 9, be enclosed with successively from the inside to the outside waterstop 7 and glass fiber tape 8.
Described cable core by pine overlap unit, nonmetal reinforcing element 4, gasket for packing 5SZ is stranded forms.
Described pine cover unit comprises loose sleeve pipe 3, in described loose sleeve pipe 3, is placed with optical fiber 1 and extraordinary water blocking yarn 2.
The stranded center position in described pine cover unit is placed with some water blocking yarns 6.
Described pine cover unit, nonmetal reinforcing element 4 are provided with more than at least one.
Optical fiber 1 in described loose sleeve pipe 3 is provided with more than at least two, and described optical fiber 1 is no more than at most 12.
Described loose sleeve pipe 3 is dry type pine sleeve pipe.
The material of described oversheath 9 is tygon or low smoke and zero halogen.
Described optical cable xsect is round shape.
Gasket for packing 5SZ is stranded forms by the nonmetal reinforcing element in two pine cover unit, three 4, one for described cable core, the nonmetal reinforcing element in described two pine cover unit, three 4, stranded being distributed in around water blocking yarn 6 of the even SZ of gasket for packing 5.
The utility model compared with the existing technology, cable configuration size is little, more soft than conventional layer strand optical cable and 8 font self-support cables, good bending property, can lay at right angle, be convenient to that Fiber to the home, its structure adopts dry type, in pine sleeve pipe, place extraordinary water blocking yarn, the stranded center clearance of loose sleeve pipe is placed water blocking yarn, cable core outer wrapping waterstop and glass fiber tape, thereby whole optical cable is without ointment, both ensured that optical cable longitudinally blocked water comprehensively, and can ensure that again construction environment was clean, whole continue and installation process convenient and swift; Because the peripheral reinforcing element of optical cable is a very crucial part, thereby adding of nonmetal reinforcing element can make optical cable rounding, saved the space of central reinforce member part, and larger pulling force can be provided, and greatly reduced the external diameter of optical cable; And in oversheath, be placed with glass fiber tape, thereby the glass fiber tape of different-thickness can make optical cable reach different pulling force, glass fiber tape also has effect that anti-mouse to a certain degree bites; Therefore, the peripheral reinforced simple and easy optical cable of dry type described in the utility model is applicable to building very much, house wiring, and Fiber to the home etc., is worthy of popularization.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model;
In figure: 1, optical fiber 2, extraordinary water blocking yarn 3, loose sleeve pipe 4, nonmetal reinforcing element 5, gasket for packing 6, water blocking yarn 7, waterstop 8, glass fiber tape 9, oversheath.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is done to following further illustrating:
The utility model comprises: cable core and oversheath 9, between cable core and oversheath 9, be enclosed with successively from the inside to the outside waterstop 7 and glass fiber tape 8, cable core by pine overlap unit, nonmetal reinforcing element 4, gasket for packing 5SZ is stranded forms, pine cover unit comprises loose sleeve pipe 3, in pine sleeve pipe 3, be placed with optical fiber 1 and extraordinary water blocking yarn 2, the stranded center position in pine cover unit is placed with some water blocking yarns 6; Wherein, pine cover unit, nonmetal reinforcing element 4 are provided with more than at least one, and the optical fiber 1 in loose sleeve pipe 3 is provided with more than at least two, and optical fiber 1 is no more than at most 12, pine sleeve pipe 3 is dry type pine sleeve pipe, and the material of oversheath 9 is tygon or low smoke and zero halogen.
