Abstract
The present invention discloses a kind of optical cable, including：The central shaft that fiber paste, multiple Loose tubes between optical fiber, optical fiber and Loose tube crack that Loose tube wraps up closely surround, the multiple Loose tube is close to be connected with water blocking layer, sheath, aramid yarn and outer jacket successively filled with cable cream, the Loose tube outside between each other.The cable configuration is simple, and oversheath can not only be effectively protected internal structure, and is easy to worker's stripping, will not damage optical fiber.
Description
Technical field
The present invention relates to optical fiber cable communication technique field, more particularly to a kind of optical cable.
Background technology
The basic structure of optical cable includes cable core and the oversheath outside cable core, and cable core includes optical fiber, Loose tube and center
Reinforcer, the optical fiber are arranged in Loose tube, and the Loose tube is arranged around center reinforcemen, are cut with scissors between adjacent two Loose tube
Connect.As domestic and international optical cable is largely laid with application, in the construction process, the construction efficiency requirement to information communication operation maintenance personnel is increasingly
The stripping of height, wherein oversheath has a great impact construction efficiency.In the prior art, the stripping of oversheath mainly has transverse direction
Stripping and longitudinal stripping.Horizontal stripping after cutter is installed, adjusts the insert depth of cutter, it is necessary to using special cable cutter
Suitable with oversheath wall thickness, outer shield can be cut by rotating a circle, and then be extracted the outer shield cut out, suitable for relatively short distance
Stripping, length easily damages optical fiber about within 1m.Longitudinal stripping method is more, common are tear rope and stripping knife
Tool.One or more tear rope is arranged with for PE in the jacket material of optical cable, in construction, by manually pulling tear
Rope stripping fiber optic cables, this method consumes one's strength very much, more demanding to operation maintenance personnel fitness；Using special longitudinal stripping cutter
When carrying out longitudinal stripping, after cutter is installed, it is suitable with oversheath wall thickness to adjust the insert depth of cutter, along the direction of cable
Being moved to tail end can cut.Special longitudinal stripping cutter easily hurts Loose tube during due to stripping, and then damages optical fiber, influences
The light characteristic and laser propagation effect of optical fiber, institute are also undesirable in this way.
The content of the invention
For above-mentioned deficiency of the prior art, the present invention provides a kind of optical cable, and the cable configuration is simple, and oversheath is not
Internal structure can be only effectively protected, and is easy to worker's stripping, optical fiber will not be damaged.
In order to reach foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of optical cable, including：Fiber paste, multiple Loose tubes between optical fiber, optical fiber and Loose tube crack that Loose tube wraps up closely are enclosed
Around central shaft, the multiple Loose tube between each other filled with cable cream, be close to be connected with successively on the outside of the Loose tube water blocking layer,
Sheath, aramid yarn and outer jacket.
Further, the outer jacket material is low smoke and zero halogen material.
Further, the water blocking layer is made of heat conduction greasy for preventing water material.
Beneficial effects of the present invention are：
Optical cable provided by the invention, its outer jacket structure is complete, has good mechanical performance, can be effectively protected internal junction
Structure；In the construction process, an openning is first scratched at each dividing strip of oversheath using cutter, is opened then along opening
Stripping, it is not necessary to use very big strength, optical fiber will not be damaged, the oversheath stripping time is short, and construction efficiency is high.

In order that the present invention can be more clearly and readily understood, below in conjunction with the attached drawing in the embodiment of the present invention,
Technical solution in the embodiment of the present invention is clearly and completely described.
A kind of as shown in Figure 1, optical cable, it is characterised in that including：Optical fiber 1, optical fiber 1 and the Loose tube 9 that Loose tube 9 wraps up
The central shaft 8 that fiber paste 2, multiple Loose tubes 9 between crack closely surround, the multiple Loose tube 9 between each other filled with cable cream 3,
It is close to be connected with water blocking layer 4, sheath 5, aramid yarn 6 and outer jacket 7 successively in the outside of Loose tube 9.
7 material of outer jacket is low smoke and zero halogen material.
The water blocking layer 4 is made of heat conduction greasy for preventing water material.
The foregoing is merely the preferred embodiment of patent of the present invention, is not intended to limit the invention patent, all at this
All any modification, equivalent and improvement made within the spirit and principle of patent of invention etc., should be included in patent of the present invention
Protection domain within.
