Abstract
The invention relates to an improved optical cable, in particular to a miniature half-tight-sleeving gas-blast optical fiber unit comprising a plurality of core bodies formed by a plurality of optical fibers and an outer tube, the plurality of core bodies adopt half-tight-sleeving arrangement and is peripherally filled with silicon oil and wrapped by an outer jacket with a microchannel.
Description
Technical field
The present invention relates to a kind of modified optical cable, particularly miniature semi-tight sleeve air-blowing fiber unit.
Background technology
The rapid expansion of suspending business and being engaged in along with many matchmakers such as Internet data communication, video request program, videophone, video conferences, broadband, high speed to physical network are had higher requirement, make and be widely used in that Fiber to the home and the transmission network of fiber to the desk becomes optimal transmission mode, the maximum shortcoming of traditional enhancing fiber unit (EPFU) be exactly the air-blowing distance limit in 500m, can not satisfy the individual user to long requirement apart from air-blowing.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of miniature semi-tight sleeve air-blowing fiber unit, comprise many optical fiber, every optical fiber places PBT tubing to constitute multicore, its outer oversheath, filling silicon oil between oversheath and multicore of being provided with.
Wherein, described miniature semi-tight sleeve air-blowing fiber unit, its feature also is: oversheath holds the semi-tight sleeve setting.
Wherein said miniature semi-tight sleeve air-blowing fiber unit, its feature also is: the oversheath surface is formed with micro-channel.
Wherein said miniature semi-tight sleeve air-blowing fiber unit, its feature also is: the oversheath skin-friction coefficient is between 0.07-0.14.
Description of drawings

Fig. 2: miniature semi-tight sleeve air-blowing fiber unit structural representation.
Fig. 3: process chart of the present invention.
Embodiment
Preferably, as shown in Figure 2, the invention provides a kind of miniature semi-tight sleeve air-blowing fiber unit, comprise many optical fiber 1, every optical fiber places PBT tubing to constitute multicore, outside it oversheath 3 is set, filling silicon oil 2 between oversheath 3 and multicore, alleviate the optical fiber problem that transmission quality descends under stressed and temperature variation.Oversheath holds the semi-tight sleeve setting.The oversheath surface is formed with micro-channel, the friction force when having reduced air-blown installation.Preferably, oversheath is made of tygon silicon core pipe, and skin-friction coefficient is between 0.07-0.14, and optical cable adopts the air blowing mounting means in pipeline, and optical cable is avoided sustaining damage when laying, and the mechanical property of optical fiber is protected.
Optical cable adopts the mode of semi-tight sleeve and uses the most simple and easy to do mounting means, and it is minimum to make that the optical cable cost is reduced to; Optical cable adopts the mode that relies on air blast to lay in pipeline, optical cable is not influenced by any tensile force, makes optical fiber obtain superior mechanical property protection; Adopt various effectively pipeline solution, can effectively solve the problem of general room optical cable lateral pressure resistant ability, and can effectively replace common leading in cable, be used for the connection of outdoor and machine room and the connection between indoor equipment and the equipment; The fiber cable branch dilatation is simple, has eliminated numerous optical fiber contacts and has improved the optical fiber utilization factor greatly; Can satisfy the long distance (air-blown installation of L＞1KM).
As shown in Figure 3, miniature semi-tight sleeve air-blowing fiber unit is finished through the step of optical fiber warehouse-in-optical fiber coloring-hemicompact oversheath installation-detection.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of claim of the present invention.
