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 flat-sandwich multiconductor optical cable.
A kind of flat-sandwich multiconductor optical cable proposed by the present invention, including：Cable core, inner sheath, enhancement layer, oversheath；
Cable core includes multiple fibre ribbons, and multiple fibre ribbons stack gradually arrangement, and each fibre ribbon includes setting gradually side by side
Multiple fiber units, the outer wall of two neighboring fiber unit is fixedly connected；
Inner sheath is coated on outside cable core, and enhancement layer is coated on outside inner sheath, and oversheath is coated on outside enhancement layer.
Preferably, enhancement layer is woven using aramid fiber.
Preferably, each fiber unit has circular cross-section, and the axis of multiple fiber units of each fibre ribbon is located at same
In one plane.
Preferably, fiber unit quantity included by multiple fibre ribbons is equal.
Preferably, fiber unit includes the optical fiber body for being located at middle part, the clad being coated on outside optical fiber body and is coated on
Hard-pressed bale layer outside clad.
Preferably, the light unit hard-pressed bale layer color of multiple fibre ribbons is all different.
Preferably, inner sheath is extruded in outside cable core.
In the present invention, the flat-sandwich multiconductor optical cable proposed, cable core includes multiple fibre ribbons, and multiple fibre ribbons stack gradually cloth
It sets, each fibre ribbon includes the multiple fiber units set gradually side by side, and the outer wall of two neighboring fiber unit is fixedly connected；It is interior
Sheath is coated on outside cable core, and enhancement layer is coated on outside inner sheath, and oversheath is coated on outside enhancement layer.Pass through above-mentioned optimization
The flat-sandwich multiconductor optical cable of design, by while greatly improving optical signal transmission performance, protecting the band-like arranged stacked of fiber unit
The flexibility of electric power is demonstrate,proved, enhancement layer carries out effective protection to cable core.
