Abstract
The utility model discloses a self-supporting butterfly optical cable-bundled optical cable. The self-supporting butterfly optical cable-bundled optical cable comprises a butterfly optical cable-bundled cable core, a steel wire hanging line and a total outer sheath; after being placed parallelly in an up-down manner, the steel wire hanging line and the butterfly optical cable-bundled cable core are wrapped and sealed through the total outer sheath; and a plurality of butterfly optical cables surround a central non-metal strengthening core and are stranded together with the central non-metal strengthening core in a forward/reverse S-Z stranding manner so as to form the butterfly optical cable-bundled cable core. The self-supporting butterfly optical cable-bundled optical cable further comprises a tearing rope arranged at the inner side of the bottom of the total outer sheath; and the external side of the total outer sheath is provided with a tearing gap corresponding to the tearing rope. The self-supporting butterfly optical cable-bundled optical cable can be used for directly connecting with optical network units (ONU) which enable optical fiber distribution boxes to output optical fibers to home, without breaking optical cables in a connection process required. One butterfly optical cable can be taken out from the optical cable directly to connect the optical network units without breaking the butterfly optical cable or the entire self-supporting butterfly optical cable-bundled optical cable in the connection process required. The self-supporting butterfly optical cable-bundled optical cable is advantageous in convenience in construction, reduction of material cost, reduction of optical joint loss and improved reliability.
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 butterfly optical cable boundling optical cable.
Background technology
At village, rural area or city neighborhood, sometimes the light splitting fiber-dividing box of EPON optical-fiber network also has distances tens of even hundreds of meters from the residential building group, existing way is to connect a common beam tube type cable that contains multi-core fiber again after the light splitting fiber-dividing box comes out, and has arrived in the village or by fiber-dividing box every optical fiber in the common beam tube type cable has been transferred to butterfly optical cable more again before the city dweller building to be connected in the resident family.Optical fiber repeatedly continues and causes construction complicated like this, the cost height, and the light loss that continues consumption is big, 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 butterfly optical cable boundling optical cable, can be used in the direct connection between the optical network unit (ONU) that the light splitting fiber-dividing box outputs to the user, the centre does not need to cut-off butterfly optical cable and whole self-bearing type butterfly optical cable boundling optical cable, directly therefrom drawing out a butterfly optical cable gets final product, make things convenient for construction, reduced consumables cost, reduce the light splicing loss, improved 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 butterfly optical cable boundling optical cable is provided, this self-bearing type butterfly optical cable concentrated light cable wrap is drawn together butterfly optical cable boundling cable core, steel wire messenger wire and total oversheath, and described steel wire messenger wire wraps up the envelope system with the up and down parallel placement of butterfly optical cable boundling cable core back by total oversheath; Described butterfly optical cable boundling cable core comprises that many butterfly optical cables are around the forward and reverse SZ twisting of the nonmetal strengthening core in center; Describedly comprise also that total oversheath bottom inside is provided with and tear rope that the position that total sheath bottom outside correspondence is torn rope also is provided with tearing port.
Preferably, described total oversheath comprises that the medial surface of medium density polyethylene sheathcoat is pasted with aluminium-plastic tape.
Preferably, G.657A described butterfly optical cable comprises optical fiber, FRP reinforcement and outward by low-smoke halogen-free flame-retardant sheath, described is butterfly by the xsect of low-smoke halogen-free flame-retardant sheath outward, and the center of xsect is provided with G.657A optical fiber, and the both sides of butterfly xsect are distributed with the FRP reinforcement.
The beneficial effects of the utility model are: a kind of self-bearing type butterfly optical cable of the utility model boundling optical cable, can be used in the direct connection between the optical network unit (ONU) that the light splitting fiber-dividing box outputs to the user, and the centre does not need to cut-off.Directly therefrom draw out a butterfly optical cable and get final product, the centre does not need to cut-off butterfly optical cable and whole self-bearing type butterfly optical cable boundling optical cable, has made things convenient for construction, has reduced consumables cost, has reduced the light splicing loss, has improved reliability.
