The utility model discloses a kind of novel buildings to make somebody a mere figurehead cable, including tight tube fiber, central tube, aramid yarn layer and oversheath；Multiple tight tube fibers are uniformly placed in the central tube, the tight tube fiber includes bare fibre, coat and fixed coating successively from the inside to the outside；Central tube is coated with aramid yarn layer, and aramid yarn layer is coated with oversheath；Two FRP reinforcing elements are symmetrically embedded in the oversheath.Not only there is the utility model good mechanical performance and environmental performance, the features such as capable of preventing outdoor unfirmly closing, gunslinging also to have good flexibility, and can support large-capacity data transmission, and laser propagation effect is good.
Description
Technical field
The utility model is related to communications optical cable technical field, especially a kind of novel building makes somebody a mere figurehead cable.
Background technology
Existing common cable configuration includes layer-stranding cable and central-beam tube type fiber optic cable, the cable cores of these optical cables be all by
The Loose tube for being set with optical fiber is constituted.Loose tube in existing optical cable mostly uses polybutylene terephthalate (PBT)（PBT）System
It is standby to form.PBT has the performances such as good solvent resistant, oil resistant, resistant to chemical etching, while having higher crystallinity, thus has
There are higher intensity and hardness, is the ideal material of conventional cable Loose tube.
But the bending performance of PBT casings is poor, attainable minimum bending radius is larger, usually in 8D（D is Loose tube
Diameter）More than, for the preferable optical fiber of bending resistance, excellent counter-bending of optical fiber cannot be given full play to using PBT casings
Performance.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of aerial cable of novel building, this
Not only there is empty cable good mechanical performance and environmental performance, the features such as capable of preventing outdoor unfirmly closing, gunslinging also to have good soft
It is soft, and can support large-capacity data transmission, laser propagation effect is good.
The purpose of this utility model is achieved through the following technical solutions：
A kind of aerial cable of novel building, including tight tube fiber, central tube, aramid yarn layer and oversheath；The central tube
Inside uniformly it is placed with multiple tight tube fibers, the tight tube fiber includes bare fibre, coat and fixed coating successively from the inside to the outside
Layer；Central tube is coated with aramid yarn layer, and aramid yarn layer is coated with oversheath；Two FRP are symmetrically embedded in the oversheath
Reinforcing element.
In the present invention, the quantity of the tight tube fiber is 2-12 roots, can support large-capacity data transmission, have
Good transmission performance.
In the present invention, the oversheath is PVC sheath, LSZH sheaths, TPU sheaths, and it is curved to avoid conventional cable
The feature of folding endurance difference, softness are flexibly applied to a variety of environment uses.
In the present invention, it is additionally provided with filled composite in the central tube.
The utility model has the beneficial effects that：
（1）With good mechanical performance and environmental performance, the features such as outdoor unfirmly closing, gunslinging can be prevented, also have good
Flexibility, and can support large-capacity data transmission, laser propagation effect is good；
（2）It is arranged with two FRP reinforcing elements in oversheath, there is good lateral pressure resistant performance and stretch-resistance
Energy；
（3）Filled composite is equipped in central tube so that tight tube fiber be not easy during laying installation and disk are stayed by
Damage.
