Abstract
The method of distributing fibers to doors adopts skeletal flat optical cable with branching windows connected to optical cable joint box for withdrawing branching fiber band and converting into tail fiber to door. The cable core in the skeletal flat optical cable has no filled ointment for easy to construction, the skeletal flat optical cable can hold more fibers, and each optical cable may have several branching windows in different axial positions. The present invention has greatly reduced cable consumption, easy construction and low cost, and is favorable to distributing fibers to doors.
Description
Technical field
The present invention relates to a kind of employing slotted core fiber ribbon cable and be used for fiber-to-the-home fiber cable laying difference cloth method for fiber.
Background technology
Along with the develop rapidly of the communication technology and industry, the transmission of optical fiber has begun therefrom long Distance Transmission progressively to short-range fiber-to-the-home direction expansion.Existing fiber mostly adopts tight sleeve optic cable and common loose jacket layer strand optical cable to the fiber cable laying cloth method for fiber at family, when needs difference house lead in optical fiber, can only cut off that optical cable continues or lay simultaneously and tap into many optical cables because of starting separator window, so not only design is complicated, the amount of expending of optical cable is big, the pipeline space that takies when laying is big, and a large amount of cables are crowded, difference continues very loaded down with trivial details, and the factice for filling in tight sleeve optic cable and the common loose jacket layer strand optical cable also brings very big inconvenience to construction.When fiber-to-the-home quantity was big, above-mentioned situation was especially serious.
Also have and adopt fiber optic tap to carry out that difference continues, but the cost height that lays, the construction trouble.
Summary of the invention
Technical matters to be solved by this invention be the deficiency that exists at above-mentioned prior art and provide that a kind of cable consumption is few, easy construction, fiber-to-the-home fiber cable laying difference cloth method for fiber that laid down cost is low.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is: adopt slotted core fiber ribbon cable, offer the difference window at the parting of optical cable, difference window place and cable splice closure join, and from the cable core of difference window, take out the fibre ribbon of drawing difference, fibre ribbon is transferred into tail optical fiber by the cable splice closure separation and is entered indoor.
Press such scheme, described difference window is that the oversheath of slotted core fiber ribbon cable is opened stripping along circumferentially all or part of, exposes one section cable core, required fibre ribbon is taken out from the skeleton grooves of cable core drawn.
Described cable splice closure includes solid cable device and fibre ribbon fan-out tail optical fiber storing tray.
Described slotted core fiber ribbon cable has 2～12 fine troughs of belt, and the fibre ribbon of placing in the fine trough of belt is 4～8 core fibre bands.
Slotted core fiber ribbon cable of the present invention can lay along vertical and/or horizontal direction, promptly inserts vertical shaft corridor and/or horizontal pipe, and offers a plurality of difference windows with the extension of cable length; Each difference window will need the fibre ribbon of difference to cut off by the window of difference the preceding that extends forward, take out the difference optical fiber that the fibre ribbon conduct of drawing a segment length continues from the difference window.
Beneficial effect of the present invention is: 1, because each difference window can will need the fibre ribbon of difference to cut off by the window of difference the preceding that extends forward, directly from the fine trough of belt of cable core, divide the inconsistent fibre ribbon that continues, and be not with factice for filling in the cable core of slotted core fiber ribbon cable, therefore, construction is laid very easy; 2, slotted core fiber ribbon cable can hold more optical fiber, can offer a plurality of difference windows on an optical cable vertically, and direct difference tens places that continue on such optical cable significantly reduce fiber-to-the-home cable consumption; 3, because required optical cable is few, and it is little to lay the pipeline space that takies, and optical cable is easy to difference, easy construction, therefore fiber-to-the-home laid down cost significantly reduces, and helps fiber-to-the-home enforcement and popularization.

Embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
First embodiment such as Fig. 1, shown in 3, be used for the access of vertical shaft corridor 2, adopt the slotted core fiber ribbon cable 5 of 3～9 fine troughs of belt, commonly used is 3,5, the slotted core fiber ribbon cable of 6 or 8 fine troughs of belt, slotted core fiber ribbon cable is offered difference window 3 at every layer, the axial length of difference window is 40～70mm, the oversheath that is about to optical cable is all opened stripping 40～70mm, form the difference window, from the cable core of difference window, take out the fibre ribbon 8 of drawing difference from the section of extending forward, be that each difference window will need the fibre ribbon of difference to cut off by the window of difference the preceding that extends forward, take out the fibre ribbon of drawing a segment length as the difference optical fiber that continues from the difference window, forward the trend that tapers off of the light pricker band in the optical cable core of Yan Shening; Fibre ribbon can be 4 cores or 6 cores, transfers into tail optical fiber 4 by cable splice closure and enters indoor.Described cable splice closure is a box body 12, the box body both sides are provided with optical cable turnover inlet, be provided with solid cable device 11 and fibre ribbon fan-out tail optical fiber storing tray in the box body, Gu cable device is made of the compaction hoop of both sides, fixedly cable core device also can be set, fibre ribbon fan-out tail optical fiber storing tray comprises fibre ribbon storing tray 9 and fan-out modular 10, and the fibre ribbon storing tray can be double-decker, is used for up-winding fiber band and tail optical fiber; The optical fiber storing tray is 1.2 meters fibre ribbon receiving spaces, and minimum bending radius is greater than 37.5mm.Slotted core fiber ribbon cable 5 links by commuting case 6 and outer cable, and the upper end of optical cable and anti-fall device 1 join.
Second embodiment as shown in Figure 2, be used for the slotted core fiber ribbon cable 5 that horizontal pipe inserts, the main difference of it and a last embodiment is that described slotted core fiber ribbon cable along continuous straight runs lays, put 7 each user and be separated required fibre ribbon, the method that its difference continues is identical with a last embodiment.
Cable splice closure of the present invention can be installed in and indoorly also can be installed in outdoorly, and its box body of cable splice closure that outdoor mounted is used must seal.
