Abstract

The utility model relates to a FTTH butterfly optical cable. The purpose is that the optical cable that provides can satisfy more installation requirements, still has the characteristics that optic fibre high -usage, simple to operate and tensile strength are good, need not to lay in addition the copper wire during outdoor installation. Technical scheme is: FTTH butterfly optical cable, this optical cable include a self -acceptance line and the two bar butterfly optical cables of parallel arrangement in self -acceptance line both sides, it is even as an organic whole through connecting portion between the oversheath of self -acceptance line and the sheath of butterfly optical cable, a self -acceptance steel wire or steel strand wires have been arranged in the oversheath of self -acceptance line, its characterized in that: there is parallel arrangement's about two optic fibre in the sheath of butterfly optical cable and is located two reinforcements of optic fibre both sides to each system of sheath two sides has a length direction extension along the optical cable to be beneficial to the recess of tearing the sheath.

Description

FTTH butterfly optical cable
Technical field
The utility model relates to a kind of communication component, specifically a kind of FTTH butterfly optical cable.
Background technology
Volume is little, cost is low owing to having for butterfly optical cable, good bending property and lay the advantages such as convenient, obtains and apply widely in Intelligent Building, digital cells, campus network and LAN (Local Area Network).But the inside of existing butterfly optical cable is only furnished with an optical fiber, often can not meet demand in use; Meanwhile, usually need to lay the wirerope being used for bulit on stilts before outdoor mounted butterfly optical cable, installation process is comparatively loaded down with trivial details.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, a kind of FTTH butterfly optical cable is provided, this optical cable can meet more installation requirements, also has the feature that fiber utilization is high, easy for installation and tensile strength is good, without the need to laying steel wire in addition during outdoor mounted.
The technical solution of the utility model is:
FTTH butterfly optical cable, this optical cable comprises a self-supporting line and is arranged in parallel in two butterfly optical cables of self-supporting line both sides; Be connected as a single entity by connecting portion between the oversheath of described self-supporting line and the sheath of butterfly optical cable; A self-supporting steel wire or steel strand wires are furnished with in the oversheath of described self-supporting line; It is characterized in that: have about two optical fiber be arranged in parallel in the sheath of described butterfly optical cable and be positioned at two reinforcements of optical fiber both sides, and sheath two sides is respectively shaped with the groove that an extension of the length direction along optical cable is beneficial to ripping sheath.
Described reinforcement is steel wire or FRP reinforcement.
The thickness of described connecting portion is 1-3mm.
Described sheath and oversheath all adopt low-smoke halogen-free flame retardant material.
Described steel wire and self-supporting steel wire all adopt phosphating steel wire.
The beneficial effects of the utility model are:
Be furnished with two optical fiber in every bar butterfly optical cable in the utility model, thus improve the utilization factor of optical fiber, meet user demand, install also very convenient; And the utility model is also provided with one for carrying high-tensile self-supporting line, when outdoor mounted without the need to laying steel wire in advance, thus simplifying installation process, improve installation effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model xsect.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, FTTH butterfly optical cable, comprises a self-supporting line and is arranged in parallel in two butterfly optical cables of self-supporting line both sides.
Described self-supporting line comprises a self-supporting steel wire 21 (or steel strand wires) and is wrapped in the oversheath 22 of self-supporting steel wire outside; Described self-supporting steel wire is phosphating steel wire and oversheath adopts low-smoke halogen-free flame retardant material; This self-supporting line effectively can improve the tensile strength of the two butterfly optical cable of self-bearing type.
Described every bar butterfly optical cable comprises two optical fiber 11 and two reinforcements 13 that extend in the same way and the sheath 12 being wrapped in optical fiber and reinforcement outside; Described two optical fiber are arranged in parallel in the center of sheath up and down, and reinforcement is then arranged in the both sides (left and right directions in figure) of optical fiber; Described reinforcement is steel wire (preferred phosphating steel wire) or FRP reinforcement and sheath adopts low-smoke halogen-free flame retardant material.
The sheath of every bar butterfly optical cable is a ribbon ennation, and the two sides (upper and lower surface in figure) of sheath is respectively shaped with one and extends the groove 14 being beneficial to ripping sheath in the longitudinal direction; Exerted oneself with different directions in the sheath both sides (both sides of side groove) of butterfly optical cable, the line direction of lower notches (in figure shown in A) just can be forced to occur rupture and be separated both sides sheath, thus separate the optical fiber being positioned at sheath center.
The structure of described butterfly optical cable is similar to the structure of existing butterfly optical cable, therefore can install existing fibre-optical splice easily; Its difference part is only the utilization factor into improving optical fiber, and meet larger demand, the internal placement of butterfly optical cable has two optical fiber.
Described self-supporting line and butterfly optical cable extend in the same way and two butterfly optical cables are arranged in the both sides of self-supporting line.Be connected as a single entity by connecting portion 3 between the oversheath of described self-supporting line and the sheath of butterfly optical cable; The thickness of this connecting portion is generally 1-3mm, is less than the thickness of butterfly optical cable, so just can reduce the structural strength of connecting portion, and when being subject to external force and pullling, connecting portion can break at first, the stripping of self-supporting line when ensureing to install; When pinching two butterfly optical cables and to both sides tearing, the length direction of connecting portion ruptures, butterfly optical cable and self-supporting line disconnected from each other.
