Abstract
The utility model relates to a minitype optical cable which is easy to wire divergently and is used in the communication field. The minitype optical cable comprises a cable core and an outer protective sleeve which coats the cable core. The minitype optical cable is characterized in that two parallel strengthening parts are embedded inside two sides of the outer protective sleeve, the cable core is composed of a plurality of fully dry type loose tubes, optical fibers are contained inside fully dry type loose tubes which are coated by the outer protective sleeve in a straight mode or in a winding mode, and a gapped loose tube state is kept between the cable core and the outer protective sleeve. The minitype optical cable has the advantages that the minitype optical cable is simple in structure, light in weight and capable of effectively reducing the diameter of the optical cable and improving the installation density of optical fibers, so that the manufacturing cost of the optical fiber is reduced; by the aid of the minitype optical cable, optical fibers are easy to draw out from the optical cable through window opening, so that divergent fiber laying is easy, and fully dry structures is beneficial to connection and installation of optical fibers; and indicating wire slots or indicating color strips are arranged on the outer protective sleeve of the optical cable, so that damage of strengthening parts can be avoided when windows are opened on the protective sleeve of the optical cable.
Description
Technical field
The utility model relates to a kind of miniature easy difference wiring optical cable that is used to communicate by letter.
Background technology
Along with the development of optical fiber communication, more and more need the lightguide cable link of big core number, low connecting loss and low installation cost to FTTB (Fiber To The Building), FTTO (Fiber-To-The-Office), FTTH directions such as (fiber-to-the-home front yards).Particularly in FTTH engineering construction process, executive cost accounts for the significant proportion that optical cable is installed budget.Therefore, simplify the expense that cable configuration will help to reduce the lightguide cable link construction.On the other hand, existing pine cover filling type optical cable necessary SC when divesting cable jacket and loose sleeve pipe and cleaning optical fiber is prone to break optical fiber; Increased cost so not only for the installation of pine cover filling type optical cable; And when being connected with patch bay, all optical fiber must be made in order, and with the ointment wiped clean on the optical fiber; For big core number wiring optical cable; The ointment of cleaning on the optical fiber will have been spent lot of manpower and material resources, and loose jacket layer strand filling type optical cable be difficult to adopt draw under the fine method difference fine, the difference very inconvenience that continues.
Summary of the invention
The utility model technical matters to be solved is the deficiency that exists to above-mentioned prior art and a kind of miniature easy difference wiring optical cable that proposes, and it is not only simple in structure, and is in light weight, and is easy under the difference finely, and is convenient to continue and install.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Include cable core and the oversheath that coats cable core; It is characterized in that described oversheath both sides are embedded with two parallel reinforcements; Described cable core is made up of many dry type pine sleeve pipes; Include optical fiber in the dry type pine sleeve pipe, dry type pine sleeve pipe to be directly putting or in the mode of putting is coated on oversheath, and keeps misunderstanding each other loose cover state between cable core and the oversheath.
Press such scheme, described cable core is outside equipped with band or aramid yarn.
Press such scheme, the corresponding reinforcement in both sides, described oversheath outside is provided with indication wire casing or indication vitta.
Press such scheme, described dry type pine casing diameter is 0.6mm～3.0mm.
Press such scheme, fiber number is 2～12 cores in the described dry type pine sleeve pipe.
Press such scheme, described reinforcement is metal or non-metal reinforcement member.
The beneficial effect of the utility model is: 1, simple in structure, in light weight, can effectively reduce optic cable diameter, and improve the dress collection density of optical fiber, thereby reduce the cost of manufacture of optical cable; 2, adopt the utility model to be easy to optical fiber extracted out from optical cable, promptly be easy to fibre under the difference, and the dry type structure is convenient to continuing and installing of optical fiber through the mode of windowing; 3, indication wire casing or indication vitta are set on cable outer sheath, can avoid damage reinforcement when cable jacket uplifting window mouth.
Description of drawings
Fig. 1 is the radial structure sectional view of first embodiment of the utility model.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
It is the miniature easy difference wiring optical cable of one 288 cored structure; The about 14mm of its optic cable diameter includes cable core and is embedded in both sides in the sheath with 6, the two parallel reinforcements 4 of oversheath that coat cable core; Described reinforcement is a metal reinforcement; The corresponding reinforcement in both sides, oversheath outside is provided with indication wire casing 3, and described cable core is made up of 24 dry type pine sleeve pipes 2 that include 12 core fibres 1, and described cable core is outside equipped with band 5; Dry type pine sleeve pipe in the mode of putting is laid in oversheath, and keeps misunderstanding each other loose cover state with unidirectional between cable core and the oversheath.
Claims (6)
1. miniature easy difference wiring optical cable; Include cable core and the oversheath that coats cable core; It is characterized in that described oversheath both sides are embedded with two parallel reinforcements, described cable core is made up of many dry type pine sleeve pipes, includes optical fiber in the dry type pine sleeve pipe; Dry type pine sleeve pipe to be directly putting or in the mode of putting is coated on oversheath, and keeps misunderstanding each other loose cover state between cable core and the oversheath.
