Description
Technical field
The invention belongs to fields of communication technology, and in particular to a kind of optical cable.
Background technology
With the continuous development of network construction, the range of the network coverage is also constantly expanding, and optical cable is in addition to from underground and building
It builds outside laying, there is also submarine layings, make somebody a mere figurehead situations such as being laid with.Self-support cable full name All Dielectric self-support refers to
Optical cable itself stiffener can bear dead weight and external load, due to being to make somebody a mere figurehead to use on electric force pole tower, match so must have
Optical cable is fixed on shaft tower by the pendant of set, furthermore the mechanical strength in order to improve its own, generally requires the reinforcement of setting center
Part, therefore weight is laid particular stress on respect to ordinary optical cable.
Invention content
The technical purpose of the present invention is to provide a kind of light-weight novel cable, and technical solution is：
A kind of self-support cable is equipped with optical cable core, steel wire twisted wire cable core and sheath, which is characterized in that the sheath includes outer
Layer sheath and internal layer sheath, the internal layer sheath include steel wire twisted wire sheath and cable jacket, and steel wire twisted wire cable core is arranged in steel
In silk twisted wire sheath, optical cable core is arranged in cable jacket, passes through messenger wire between the steel wire twisted wire sheath and cable jacket
Connection, the outer protective sleeve are then wrapped in the outer surface of internal layer sheath, are equipped in the internal layer sheath and gasket for packing is stranded in one
The more optical cable units risen, the optical cable unit is made of dry type Loose tube and the optical cable core, the optical cable core by
Using the multifiber composition that water blocking yarn is wrapped, the gap between optical cable unit, gasket for packing and internal layer sheath uses material water-proof material
Filling, the material water-proof material includes water blocking yarn.
On the basis of said program, it is further improved or preferred scheme further includes：
The outer protective sleeve, internal layer sheath and messenger wire are polythene material.The dry type Loose tube is poly terephthalic acid
Butanediol ester material.
The optical fiber is G.654 optical fiber.
The line density of the water blocking yarn is 200~1500m/kg
The outer diameter of the dry type pine set unit is 2.5~3.0mm.
The outer diameter for wrapping up the first jacket portions of optical cable core is more than the second jacket portions of wrapped wire twisted wire cable core, and described the
The outer diameter of one jacket portions is 7.5mm, and the distance between the first sheath and the second sheath both ends are 14mm.
Advantageous effect：
Self-support cable structural planning of the present invention is reasonable, have the advantages that it is light, be suitable for long range aerial laying, and construct
It is convenient, it is suitble to promote the use of.
