Abstract
The utility model discloses a kind of twin-core butterfly optical cable, comprise integrated two interconnective plastic sheaths, fibre-optic package is at the center of sheath, and encapsulate two reinforcements in sheath, reinforcement is positioned at the both sides of optical fiber; The width of two sheath coupling parts is less than the width of sheath.Two optical fiber of this optical cable are encapsulated in two sheaths respectively, and two optical fiber are relatively independent, are independent of each other, and occur that abnormal probability reduces greatly simultaneously, can effectively ensure the normal of optical fiber communication.
Description
Technical field
The utility model relates to a kind of twin-core butterfly optical cable.
Background technology
Optical fiber is a kind of fiber be made up of glass or plastics, can be used as light conduction instrument.Based on optical fiber good confidentiality, the characteristic such as capacity is high, speed is high, optical fiber has a wide range of applications in the communications.
As shown in Figure 1, it is a kind of traditional single core butterfly optical cable, packaged fiber in plastic sheath, the shortcoming of single core butterfly optical cable is if fibercuts, easily causes the interruption of optical fiber communication, so generally adopt twin fiber cable at important transmission network of registering one's residence, the object of use twin fiber cable is the needs due to equipment, twin-core uses all simultaneously, or wherein an optical fiber uses as spare fibre, in case wherein an optical fiber occurs abnormal.
Figure 2 shows that the structural representation of conventional a kind of twin fiber cable, two optical fiber encapsulated in plastic sheath side by side, but because the optical fiber in this kind of twin fiber cable is close to, except the exception that the factor of optical fiber itself causes, by the external world carry out causing squeeze, pressure, the situation such as curved all can impact two optical fiber simultaneously.So when this kind of twin fiber cable is generally as spare fibre, have little significance.
Utility model content
The purpose of this utility model is to provide a kind of twin-core butterfly optical cable, and two optical fiber are relatively independent, are independent of each other, and occurs that abnormal probability reduces greatly simultaneously.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise integrated two interconnective plastic sheaths, fibre-optic package is at the center of sheath, and encapsulate two reinforcements in sheath, reinforcement is positioned at the both sides of optical fiber; The width of two sheath coupling parts is less than the width of sheath.
Preferably, one end of a sheath connects wrap attachment.
Preferably, wrap attachment is integrated messenger jacket with sheath, encapsulation messenger wire reinforcement in messenger jacket.
Preferably, sheath material therefor is flame retardant type tygon, and reinforcement material therefor is that steel wire or non-metal reinforcement member are as KFRP, GFRP, QFRP etc.
Preferably, messenger jacket material therefor is flame retardant type tygon, and messenger wire reinforcement material therefor is steel wire.
Preferably, the width of two sheath coupling parts is 0.5 millimeter.
The beneficial effect that this butterfly optical cable produces is:
1, two optical fiber are encapsulated in two sheaths respectively, and two optical fiber are relatively independent, are independent of each other, and occur that abnormal probability reduces greatly simultaneously, can effectively ensure the normal of optical fiber communication.
2, the coupling part between optical cable is 0.5mm, play fixing while, two optical cables can also well be separated each other, can as common two single core butterfly optical cables after separation.
Accompanying drawing explanation
Figure 1 shows that traditional single core butterfly optical cable structural representation.

With reference to figure 3, Figure 3 shows that the cross-sectional view of an embodiment of a kind of twin-core butterfly optical cable of the present utility model.In the present embodiment, twin-core butterfly optical cable comprises integrated two interconnective plastic sheaths 1, and optical fiber 11 is encapsulated in the center of sheath 1, encapsulation two reinforcements 12 in sheath 1, and reinforcement 12 is positioned at the both sides of optical fiber 11; The width of two sheath coupling parts 2 is less than the width of sheath 1.
With reference to figure 4, in an embodiment of the present utility model, one end of a sheath 1 connects wrap attachment 3, and the twin-core butterfly optical cable of this structure may be used for outdoor.
Further, with reference to figure 4, in an embodiment of the present utility model, wrap attachment 3 is integrated messenger jacket 31 with sheath 1, encapsulation messenger wire reinforcement 32 in messenger jacket 31.
With reference to figure 3, in an embodiment of the present utility model, sheath 1 material therefor is flame retardant type tygon, and reinforcement 12 material therefor is that steel wire or non-metal reinforcement member are as KFRP, GFRP, QFRP etc.
With reference to figure 4, in an embodiment of the present utility model, messenger jacket 31 material therefor is flame retardant type tygon, and messenger wire reinforcement 32 material therefor is steel wire.
With reference to figure 3, Fig. 4, in an embodiment of the present utility model, the width of two sheath coupling parts 2 is 0.5 millimeter, play fixing while, two optical cables can also well be separated each other, can as common two single core butterfly optical cables after separation.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
