Description
Technical field
The present invention relates to optical cable technology field more particularly to a kind of tension access optical cables.
Background technique
Along with the rapid development of IT wave, optical cable plays an increasingly important role in communication process, makees
For the important medium that information is propagated, the transinformation of optical fiber is most important, existing facing to more and more massive informations
Single fiber cable more seems awkward in transmittability, and more single fiber cables, which are simply banded together, to be made
With then it is low to be easy loose and tensile capacity for it, and the outer wall of optical cable is also easily damaged, a kind of with big it is therefore necessary to provide
The optical cable of capacity communication ability meets growing use demand, preferably serves users.
Summary of the invention
To solve technical problem present in background technique, the present invention proposes a kind of tension access optical cable.
A kind of tension access optical cable proposed by the present invention, including：Cable core, Loose tube, enhancement layer, restrictive coating；
Cable core includes multifiber unit, and Loose tube is set in outside cable core, and Loose tube internal clearance is filled with fiber paste, is reinforced
Layer is coated on outside Loose tube, and restrictive coating is coated on outside enhancement layer.
Preferably, enhancement layer is made of aramid fiber.
Preferably, tear rope is equipped in Loose tube side wall.
Preferably, tear rope is axially extending along Loose tube.
Preferably, two tear ropes are equipped in Loose tube side wall, two tear ropes are located at cable core two sides.
Preferably, multifiber unit outer wall color is different.
Preferably, separation layer is equipped between Loose tube and enhancement layer, separation layer is formed using aluminium-plastic tape is wrapped.
In the present invention, the tension access optical cable proposed, including：Cable core, Loose tube, enhancement layer, restrictive coating；Cable core includes
Multifiber unit, Loose tube are set in outside cable core, and Loose tube internal clearance is filled with fiber paste, and enhancement layer is coated on outside Loose tube
Portion, restrictive coating are coated on outside enhancement layer.By the tension access optical cable of above-mentioned optimization design, cable core is set in by Loose tube
Protection is realized to the fiber unit of cable core in outside, while the fiber paste filled in Loose tube is played to cable core buffer function, enhancement layer
Effective protection cable core is particularly suitable for applying in optical fiber sensing not by damage outside cable core with restrictive coating.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of tension access optical cable proposed by the present invention.
Specific embodiment
As shown in FIG. 1, FIG. 1 is a kind of structural schematic diagrams of tension access optical cable proposed by the present invention.
Referring to Fig.1, a kind of tension access optical cable proposed by the present invention, including：Cable core, Loose tube 1, enhancement layer 2, restrictive coating
3；
Cable core includes multifiber unit 4, and Loose tube 1 is set in outside cable core, and 1 internal clearance of Loose tube is filled with fiber paste,
Enhancement layer 2 is coated on outside Loose tube 1, and restrictive coating 3 is coated on outside enhancement layer 2.
In the present embodiment, the tension access optical cable proposed, including：Cable core, Loose tube, enhancement layer, restrictive coating；Cable core
Including multifiber unit, Loose tube is set in outside cable core, and Loose tube internal clearance is filled with fiber paste, and enhancement layer is coated on loose set
Outside pipe, restrictive coating is coated on outside enhancement layer.By the tension access optical cable of above-mentioned optimization design, it is set in by Loose tube
Outside cable core, protection is realized to the fiber unit of cable core, while the fiber paste filled in Loose tube is played to cable core buffer function, is added
Strong layer and restrictive coating the effective protection cable core outside cable core is particularly suitable for applying in optical fiber sensing not by damage.
In a specific embodiment, enhancement layer 2 is made of aramid fiber, while guaranteeing mechanical strength, does not influence electricity
The weight of cable.
In the specific embodiment of Loose tube, it is equipped with tear rope 5 in 1 side wall of Loose tube, is convenient for cable core from outer layer sheath
Middle removing.
In further specific embodiment, tear rope 5 is axially extending along Loose tube 1, further tears convenient for tear rope.
In other specific set-up modes of Loose tube, two tear ropes 5, two tear ropes 5 are equipped in 1 side wall of Loose tube
It is located at cable core two sides.
In other specific embodiments, 4 outer wall color of multifiber unit is different.
In another specific embodiment, separation layer 6 is equipped between Loose tube 1 and enhancement layer 2, separation layer 6 uses plastic-aluminum
Composite band is wrapped to be formed, by the way that separation layer is arranged, on the one hand in use, aluminum metal layer guarantees heat in optical cable in warming system
Surface is uniformly distributed, and on the other hand, fiber paste is effectively isolated in Loose tube by separation layer.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
