Description
Technical field
The utility model is related to optical cable technology fields, and in particular to a kind of skeleton all dielectric optical fiber ribbon cable of pressure resistance.
Background technology
With the development of optical communications industry, the range of network distribution is more and more extensive.For near mountain forest field, rail
When severe region carries out the network coverage, current fiber cable laying mode is mainly grooving laying optical cable or is applied using pipeline
If optical cable.However, the bad environments near mountain forest field or rail, difficulty of construction is larger, so that laid down cost is high, construction risk
The problem of degree is high low with efficiency.Also, optical cable uses outdoors for a long time, often is hit to nibble with mouse ant by thunder and lightning and gnaw, destroys optical cable.
Invention content
For the prior art there are above-mentioned technical problem, the utility model provides the bone of a kind of pressure resistance, stretch-proof and high-ductility
Posture all dielectric optical fiber ribbon cable.
To achieve the above object, the utility model provides following technical scheme：
It provides a kind of pressure resistance skeleton all dielectric optical fiber ribbon cable, including skeleton, is opened on the backbone length direction
Fiber optic ribbon cable core wire in skeleton grooves, the embedded skeleton grooves, the skeleton is outer to be arranged with internal layer, external sheath layer successively outward from interior
With fire-retardant nylon layer, armouring has the first strengthening core in the skeleton, and armouring has second between the internal layer and the external sheath layer
Strengthening core.
Wherein, the skeleton grooves are set as four, and four skeleton grooves are uniformly opened on the skeleton.
Wherein, the cross section of the skeleton grooves is c-type, and the opening size of the skeleton grooves is less than the vallecular cavity of the skeleton grooves
Diameter.
Wherein, the fiber optic ribbon cable core wire includes Loose tube, the fibre ribbon in the Loose tube, the Loose tube and institute
It states between fibre ribbon filled with fiber paste.
Wherein, the first strengthening core armouring is in the center of the skeleton.
Wherein, second strengthening core is equipped at least two, and at least two strengthening core is uniformly distributed in described
Between layer and the external sheath layer.
Wherein, first strengthening core and second strengthening core are FRP round bar strengthening cores.
Wherein, the external sheath layer is low smoke and zero halogen external sheath layer.
The beneficial effects of the utility model：
The skeleton all dielectric optical fiber ribbon cable of a kind of pressure resistance of the utility model, using the skeleton of high intensity and skeleton grooves branch
Support is embedded in the Loose tube of high durometer polymeric extrusion molding, armouring strengthening core in skeleton and in jacket layer, and use three sheaths in addition
Structure, optical cable have the performance of superpower pressure resistance, stretch-proof and high-ductility, can directly be laid on the spot, the standard without early period
It is standby to work or using facilities resources such as existing pipeline, grooves, considerably increase flexibility and the operability of construction；And the light
The high-ductility performance of cable itself can be suitably used for mouse ant and spread unchecked grade bad environments region.
