Abstract
The utility model relates to a unit type optical fiber belt optical cable used for the transmission field of the communication, comprising optical fiber belts folded with each other, a bundling element and an outer protecting sleeve. The utility model is characterized in that each optical fiber belt is sheathed with a sub protecting sleeve and is configured with a tensile fiber, the optical fiber belts are 1-12 strips, the optical fibers of the optical fiber belts are 2-24 roots, the bundling element is a bundling yarn, a bundling belt or a polyester belt, the outer protecting sleeve is a polyvinyl chloride outer protecting sleeve or a halogen-free fire resistant polythene outer protective sleeve, and the tensile fiber can be an aramid fiber yarn or a glass fiber. The beneficial effects of the utility model are that each optical fiber belt is provided with an independent reinforcing element and a protecting sleeve, the utility model not only reinforces the intensity of optical cables of the integral optical fiber belts, but also the optical fiber belts can not be penetrated through plastic sleeve tubes after the optical cables are discharged and split, and unit type optical fiber belt optical cable has high intensity and good protecting performance and is able to prevent the damage caused by outer force in the process of being installed and used so as to be convenient to be installed and used.
Description
Technical field
The utility model relates to a kind of modular optical fibre band optical cable that is used for field of communication transmission.
Background technology
Fibre ribbon is owing to have the density of optic fibre height, is convenient to the characteristics of separated time and butt joint and is widely used.Existing optical fibre band optical cable as stern fast all adopts the central beam tube type structure; constitute by superimposed fibre ribbon, binder, traction-resistant fibre and oversheath; fibre ribbon does not wherein have independent enhancing element and sheath; such fibre ribbon need add when going out the cable separated time wears plastic casing; this not only gives and uses and wiring has brought inconvenience; and the fibre ribbon intensity that goes out cable is low, and protective value is poor, is easy to impaired.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and a kind of strong modular optical fibre band optical cable of fibre ribbon protective value behind separated time and the separated time of being convenient to is provided.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include the fibre ribbon 1 that is superimposed, and dressing part 6 and oversheath 5, its difference is that every fibre ribbon is with sub-sheath 2 and configuration traction-resistant fibre 3.
Press such scheme, described fibre ribbon 1 is 1～12, and the optical fiber of every fibre ribbon is 2～24; Described dressing part 6 is for pricking yarn, band or polyester belt; Described oversheath is Polyvinylchloride oversheath or Zero halogen flame resistance polyethylene oversheath; Described traction-resistant fibre can be aramid yarn or glass fibre.
The beneficial effects of the utility model are every fibre ribbon is provided with independently reinforcing element and protection sheath; this has not only strengthened the intensity of whole optical fibre band optical cable; and the fibre ribbon that goes out behind the cable separated time need not be worn plastic casing; its intensity height, protective value are good; can prevent to install the damage that is caused with the power effect of use China and foreign countries, use and installation brings convenience thereby give.
Description of drawings
Fig. 1 is the radial section figure of fibre ribbon among the utility model embodiment.
Fig. 2 is the radial section figure of an embodiment of the utility model.
Fig. 3 is the radial section figure of another embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
First embodiment as shown in Figure 1, 2, include fibre ribbon 1, fibre ribbon has 12 optical fiber, and fibre ribbon is covered with traction-resistant fibre 3 outward and is with sub-sheath 2, constitutes platypelloid type tight tube fiber band thus, after being superimposed, wraps up by each tight tube fiber band with dressing part 6, constitute cable core, fibre ribbon can be 4～6, can lay the traction-resistant fibre 7 of optical cable and wrap up one deck again with dressing part 6 outside cable core, coat with oversheath 5 at last, oversheath is the Zero halogen flame resistance polyethylene oversheath.
Second embodiment shown in Fig. 1,3, the main difference part of it and a last embodiment is that the endoporus interface of oversheath is a rectangle, the outside is circular, in the rectangle endoporus, be provided with the cable core that the tight tube fiber band with dressing part 6 parcel is constituted, adopt this outer jacket structure both can avoid the upset of cable core in oversheath, also can save sheath material, reduce optic cable diameter, be convenient to install.
Claims (6)
