Detailed description of the invention
In order to be illustrated more clearly that this utility model, the utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, this microflute type air-blowing minisize optical cable includes:
(1) Loose tube 3, sheath 4, tensile elements 5.Wherein, the material of Loose tube 3 uses Merlon, and the material of sheath 4 uses high density polyethylene (HDPE).
(2) being provided with many colored optical fibers 1 in described Loose tube 3, the color of described many colored optical fibers 1 is different, is filled with ointment 2 between many colored optical fibers 1 in Loose tube 3.Wherein, the quantity of described many colored optical fibers (1) is specially 24.
(3) described sheath 4 is the outermost layer of this micro optical cable, and sheath 4 is wrapped in outside described Loose tube 3, and described tensile elements 5 uses the aramid yarn of softness and tension, is arranged between Loose tube 3 and sheath 4.Wherein, tensile elements 5 quantity is 1.
Existing a kind of air-blowing minisize optical cable shown in Fig. 2, inside is made up of center reinforcement and optical fiber bundle unit, center reinforcement is arranged along the axis of outer jacket, and optical fiber bundle unit is surrounded on outside the reinforcement of center, and the great advantage of this air-blowing minisize optical cable is compact conformation, optical transport can be met, better mechanical property, diameter dimension is 5.6mm, and the minimum bending radius before installation is 112mm, minimum bending radius after installation is 56mm, and weight is 35Kg/km.And microflute type air-blowing minisize optical cable of the present utility model, do not use center reinforcement, but with aramid yarn as tensile elements, aramid yarn has the soft feature with tension, so the microflute type air-blowing minisize optical cable diameter dimension that this utility model provides is not more than 2.8mm, cable size is little, weight is not more than 5.8Kg/km, and unit weight is lighter, and the minimum bending radius before installation is not more than 56mm, minimum bending radius after installation is not more than 28mm, and lateral pressure resistant is good with bending resistance.
