Abstract
The invention discloses an optical cable which comprises an optical fiber, a loose tube which sleeves the optical fiber, an aramid fiber layer which coats the loose tube, and an outer sheath which sleeves the aramid fiber layer. A release agent layer is arranged between the loose tube and the aramid fiber layer. A problem of thermal deformation in the process of production is effectively solved, the qualified rate of products is ensured, the appearance of defective products is avoided, and the production cost is indirectly reduced.
Description
Technical field
The present invention relates to optical fiber transmission technique field, more particularly, it relates to a kind of optical cable.
Background technology
In prior art, in outer sheathing, Loose tube can become Loose tube because being heated
Shape.This thermal deformation is because when oversheath is extruded, heat is caused by aramid fiber Es-region propagations
Aramid layers heat shrinkable, because aramid layers are that denser is wrapped on Loose tube, causes pine
Sleeve stress deforms, and so as to the roundness for causing Loose tube does not reach production requirement, causes optical fiber
Signal attenuation increases, and affects the final qualification rate of product.
The content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of optical cable, its
Efficiently solve the problems, such as thermal deformation in production process, it is ensured that the qualification rate of product, it is to avoid
The appearance of defect ware, reduces production cost indirectly.
To solve the above problems, the technical solution adopted in the present invention is as follows：
A kind of optical cable, including optical fiber, the Loose tube being set on optical fiber, are wrapped on Loose tube
Aramid layers and the oversheath that is set in aramid layers, arrange between the Loose tube and aramid layers
There is parting agent layer.
Preferably, also including the soft sheath being wrapped on oversheath, the soft sheath is PA12
Material.
Preferably, the soft sheath thickness is 0.1-0.5cm.
Preferably, the external sheath layer material is low smoke and zero halogen material.
Preferably, the parting agent layer is oiliness parting agent layer.
Preferably, screen layer is provided between the optical fiber and Loose tube, the optical fiber is many,
Laid out in parallel is simultaneously wrapped in screen layer.
Preferably, the screen layer is aluminium strip layer.
Preferably, optical fiber ointment is filled between the optical fiber and screen layer.
Compared to existing technology, the beneficial effects of the present invention is：
The present invention efficiently solves the problems, such as thermal deformation in production process, it is ensured that product it is qualified
Rate, it is to avoid the appearance of defect ware, reduces production cost indirectly；In Loose tube and aramid layers
Between coat one layer of oiliness mould release, the effect of oiliness mould release is lubrication so that Loose tube
And aramid layers between adhesive force reduce, such aramid layers when temperature distortion, due to oiliness
The effect of mould release so that the active force of aramid layers is weakened, it is impossible to cause Loose tube to deform,
Ensure the overall normal structure of optical fiber, it is ensured that the stability of fiber-optic signal transmission.In addition, using
Thickness 0.1-0.5cm nylon 12 (PA12) as soft sheath, the hardness of nylon 12 is old
Mouse cannot gnaw, and nylon is self-lubricating material, and frictional force is very low, and easy poling is easy to light
Cable construction in later period is used.
