Technical field:

This utility model relates to fiber optic cable configuration, particularly relates to novel low core number access optical cable and group Close optical cable.

Background technology:

Due to popularizing of fiber to the home service, the demand of compact little core number optical cable increases year by year, As it is shown in figure 1, be currently employed for fiber-to-the-home compact little core number covered wire cable general structure Square jacket is set for outside, two reinforcements are set in sheath, parallel between two reinforcements set Putting optical fiber, optical fiber is with reinforcement geometric center point-blank.Although these optical cables have good Good mechanical performance, hot property, and be widely used in fiber to the home, but, this wherein wrap Flat optical cable containing two reinforcements has the disadvantage in that 1, sectional area is relatively big, causes material Material waste；2, can only be to a direction bending, bending direction is fixed, and has installation limitation, It is not suitable for the installation of small space；3, reinforcement extruding optical fiber during transverse compression, easily makes Becoming optical fiber damage, anti-compression properties is poor.

Utility model content:

The purpose of this utility model is to provide novel low core number access optical cable and combination optical cable, solves Certainly current square optical cable volume is big, bending property is poor, resistance to compression is poor, the asking of narrow application range Topic.

In order to solve above-mentioned technical problem, this utility model provides novel low core number access optical cable, Including oversheath, reinforcement and optical fiber, described reinforcement and described optical fiber all with described oversheath Axis be arranged in parallel, the cross section of described oversheath is circular, is coated with in described oversheath Two described reinforcements along the axis lateral symmetry setting of described oversheath and at least one institute Stating optical fiber, described optical fiber is arranged on the center deviateing described oversheath between two described reinforcements On the position of axis.

Further, the diameter of described reinforcement is at least above the diameter of described optical fiber.

Further, the quantity of described optical fiber is two, and two described optical fiber is respectively along outside described The another arranged on both sides of axis of sheath is arranged.

Further, the outside of described optical fiber is enclosed with plastic layer with tight set mode or pine set mode.

Further, it is filled with water absorbing material 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.

This utility model additionally provides combination optical cable, including a kind of novel low core number as above Access optical cable is the optical cable unit that basic structure is combined into, and is wrapped in institute the most successively Stating the reinforcing sleeve structure outside optical cable unit and jacket structure, in described optical cable unit, collection pencil is parallel It is arranged with novel low core number access optical cable described at least two.

Further, the quantity of described novel low core number access optical cable is two, and described optical cable list Unit also includes the copper cash of more than at least two, and described copper cash is symmetricly set on described reinforcing sleeve structure Longitudinal both sides of axis, two described novel low core number access optical cables are along two described copper cash The arrangement of geometry mediad both sides horizontal arrays.

Advantage of the present utility model: this utility model embodiment is circular by using cross section Optical cable make whole optical cable cross section diminish, one is to save material, economical more preferably, Two be use cross section be circular optical cable so that optical cable can bend in any angle, because of This goes for the installation of the narrow and small rotating channel of optical cable；It is internal partially that optical fiber is arranged on whole sheath The position of off-axis line and the twice of a diameter of described fibre diameter of reinforcement, so that light Cable compression in any direction is impaired all without making optical fiber, and the fibre that the optical cable of this spline structure accommodates Dimension is the most wider, so carrying to aspects such as antennas at LAN, data center, optical fiber For wider application, beyond fiber to the home field.

Detailed description of the invention:

For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, It is described in detail below in conjunction with the accompanying drawings and the specific embodiments.

Embodiment 1: as in figure 2 it is shown, provide novel low core number in this utility model embodiment Access optical cable, including 1, two reinforcements 2 of oversheath and two optical fiber 3, oversheath 1 Cross section is circular, is coated with two axis lateral symmetry along oversheath 1 and sets in oversheath 1 The optical fiber 3 that the reinforcement 2 put and two another both sides of the axis along oversheath 1 are arranged, reinforcement The diameter of 2 is more than optical fiber 3 diameter, and optical fiber 3 is outside is enclosed with plastic layer 4 in tight set mode.

Embodiment 2: as it is shown on figure 3, provide a kind of circular light in this utility model embodiment Cable, including 1, two reinforcements 2 of oversheath and four optical fiber 3, the cross section of oversheath 1 For circle, in oversheath 1, it is coated with adding of two axis lateral symmetry settings along oversheath 1 The optical fiber 3 that the another both sides of strong part 2 and four axis along oversheath 1 are arranged；Reinforcement 2 Diameter, more than the diameter of optical fiber 3, is filled with water absorbing material 5 between optical fiber 3 and oversheath 1.

In specific embodiment of the utility model, reinforcement 2 is made for steel wire or fiberglass.

This utility model embodiment makes whole optical cable by using the optical cable that cross section is circular Cross section diminish, one is to save material, economical more preferably, two be use cross section be Circular optical cable, so that optical cable can bend in any angle, therefore goes for narrow and small The installation of optical cable in rotating channel；Optical fiber 3 is arranged on the position of whole sheath internal deviation axis And be arranged in the border of two reinforcements 2, and the diameter of reinforcement 2 is straight more than optical fiber 3 Footpath, so that the compression that optical cable is in any direction is impaired all without making optical fiber 3, therefore optical cable Anti-compression properties good, and this spline structure optical cable accommodate number of fibers the most wider, So in multiple fields application such as LAN, data center, optical fiber to antenna.
