Further, the outside of described optical fiber is tightly to overlap mode or loose cover mode is enclosed with plastic layer.
Further, water-absorbing material is filled with between described optical fiber and described oversheath.
Further, described reinforcement is made up of FRP, KFRP, steel wire or composite fibre materials.
Further, the material of making of described optical fiber is glass or synthetic plastic.
Present invention also offers combination optical cable, comprising a kind of novel low core number access optical cable as above is the optical cable unit that basic structure is combined into, and the reinforcing sleeve structure be wrapped in successively from inside to outside outside described optical cable unit and jacket structure, in described optical cable unit, boundling shape parallel shows at least two described novel low core number access optical cables.
Further, the quantity of described novel low core number access optical cable is two, and described optical cable unit also comprises the copper cash of more than at least two, described copper cash is symmetricly set on longitudinal both sides of the axis of described reinforcing sleeve structure, and two described novel low core number access optical cables are along the horizontal array arrangement in geometry mediad both sides of two described copper cash.
Advantage of the present invention: the embodiment of the present invention by adopt xsect be circular optical cable make whole optical cable xsect diminish, one is to save material, better economical, two is adopt xsect to be that circular optical cable can make optical cable can bend in any angle, therefore goes for the installation of the narrow and small rotating channel of optical cable; Optical fiber is arranged on the twice that the whole position of sheath internal deviation axis and the diameter of reinforcement are described fibre diameter, can make optical cable compression in any direction that optical fiber all can not be made impaired, and how much wider the fiber number that the optical cable of this spline structure holds is, apply widely so provide in LAN (Local Area Network), data center, optical fiber to antenna etc., exceed fiber to the home field.
