Abstract
The utility model discloses a self-supporting tight-buffered fiber bunched cable, which includes a tight-buffered fiber bunched cable core, a steel suspension wire and an overall outer sheath. The steel suspension wire and the tight-buffered fiber bunched cable core are parallelly arranged up and down and then are wrapped and sealed by the overall outer sheath. The tight-buffered fiber bunched cable core comprises a plurality of tight-buffered fiber single-core indoor cables winding a central FRP strengthening core and twisting forward and reverse in a manner of SZ. Water blocking yarn is arranged in twisting gaps among the tight-buffered fiber single-core indoor cables. The inner side of the bottom of the overall outer sheath is provided with rip cord. Through the above method, the self-supporting tight-buffered fiber bunched cable can be used for direct connection of optical network units (ONU) outputting from an optical splitter to dozens of home users or business building users. During construction, cables cannot be cut off for connection, and other cables are not required for through connection in the middle. Therefore, link optical fiber splice losses are minimized, construction cost is reduced, and reliability is raised.
Description
Technical field
The utility model relates to cable and optical cable and makes the field, particularly relates to a kind of self-bearing type tight tube fiber boundling optical cable.
Background technology
In the rural area or city dweller's high-rise residential building or business office building, sometimes the light splitting fiber-dividing box of EPON optical-fiber network also has distances tens of even hundreds of meters from each resident family or each user's office, existing way is to connect again a common beam tube type cable that contains multi-core fiber from the light splitting fiber-dividing box after out, arrived behind the residence stairs unit or a floor of ShangWu Building after, by fiber distribution box butterfly optical cable on the every optic fibre switching in the common beam tube type cable is connected in the resident family again.Optical fiber connects repeatedly that to shine into construction complicated like this, and cost is high, and splicing loss is large, the problems such as reliability reduction.
Summary of the invention
The technical matters that the utility model mainly solves provides a kind of self-bearing type tight tube fiber boundling optical cable, can be used in and connect the direct connection that outputs to dozens of domestic consumer or ShangWu Building user's optical network unit (ONU) from optical splitter, can not cut off optical cable during construction draws and connects, the centre does not need to transfer with other optical cable again, reduced the link fiber splicing loss, reducing the construction costs, improve reliability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of self-bearing type tight tube fiber boundling optical cable is provided, this self-bearing type tight tube fiber concentrated light cable wrap is drawn together tight tube fiber boundling cable core, steel wire messenger wire and total oversheath, described steel wire messenger wire and tight tube fiber boundling cable core up and down parallel placement afterwards by total oversheath parcel envelope system; Described tight tube fiber boundling cable core comprises many tight tube fiber list core inside cables around the forward and reverse SZ twisting of center FRP strengthening core, and the twisting gap between the tight tube fiber list core inside cable is provided with water blocking yarn; Described total oversheath bottom inside is provided with tears rope.
Preferably, described total oversheath comprises that the medial surface of Polyvinylchloride sheathcoat is provided with the vertical alclad band of parcel tight tube fiber boundling cable core.
Preferably, described tight tube fiber list core inside cable comprises that G.657A tight tube fiber wraps up and aramid fiber cushion and outer by low-smoke halogen-free flame-retardant sheath successively.
The beneficial effects of the utility model are: a kind of self-bearing type tight tube fiber of the utility model boundling optical cable, can be used in and connect the direct connection that outputs to dozens of domestic consumer or ShangWu Building user's optical network unit (ONU) from optical splitter, can not cut off optical cable during construction draws and connects, the centre does not need to transfer with other optical cable again, reduced the link fiber splicing loss, reducing the construction costs, improve reliability.
