Description
Technical field
The present invention relates to a kind of dished optical cable, particularly the easily branched butterfly optical cable with oversheath.
Background technology
Fiber To The Building to FTTB(along with photoelectric communication), the FTTO(Fiber-To-The-Office), FTTH(fiber-to-the-home front yard) etc. the development of direction, butterfly optical cable is used in Access Network in a large number.For simplifying construction maintenance, a kind of self-bearing type butterfly optical cable that can use at indoor and outdoors simultaneously is widely used; Outdoor section its can be used as that self-support cable is built on stilts to be used; Before optical cable is registered one's residence the messenger wire element cut off and be fixed on the special-purpose fixator, the residue optical cable removes and becomes butterfly optical cable behind the messenger wire element and introduce indoorly, cooperates fast connecting joint or optical fiber cold joint to use.Traditional butterfly optical cable lays inconvenience, and difficulty of construction is higher, and self-supporting intensity is lower.
Chinese patent application number: 201220437851.9 disclose a kind of self-bearing type butterfly photoelectric mixed cable, it comprises the butterfly sheath, be laid with optical communication element in the middle of it is characterized in that in the butterfly sheath, difference laying wire in both sides in the butterfly sheath, the outer upside of butterfly sheath is connected with messenger wire.Such structure construction gets up more loaded down with trivial details, in the future if carry out the Full Fibre Network transformation, necessary gigantic project, the time-consuming ground rewiring of taking a lot of work.
Chinese patent application number: 201220363366.1 disclose a kind of photoelectricity mixing ripple cable; comprise optical communication element, communication unit and oversheath; this optical communication element comprises at least one pair of fiber cores; this communication unit comprises at least one electronic communication link; its carrying of the ripple cable of this structure and resistance to tension are poor; the cable major part is exposed in the extraneous air, and after through long-term exposing to the sun and rain, the protective effect that the outer jacket of cable plays is little.
In laid processes, register one's residence in the place of difficulty maximum often photoelectricity, and cable needs branch, yet the cable of common mechanical better performances is difficult when branch.Traditional cable need to draw a messenger wire specially when laying in addition, is used for reducing the load of cable, this so-called messenger wire is generally exposed steel cable, and long term exposure is in air, and messenger wire is easily by corrosion, even disconnect, thereby can not play the effect of messenger wire place of cable tension.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of self-supporting intensity high, lay simple to operate, time saving and energy saving and can improve the easily branched butterfly optical cable with oversheath of cable machinery performance.
Purpose of the present invention is achieved through the following technical solutions: the easily branched butterfly optical cable with oversheath, it comprises the messenger wire sheath, oversheath, connecting portion, messenger wire and butterfly optical cable unit, messenger wire sheath and oversheath be arranged in parallel, link to each other by connecting portion between messenger wire sheath and the oversheath, many messenger wires are arranged at the inside of messenger wire sheath, the butterfly optical cable unit is arranged at the inside of oversheath, the butterfly optical cable unit comprises a plurality of butterfly sheaths, optical fiber, reinforcement and open the stripping point, a plurality of butterfly sheaths are set up in parallel, the center of each butterfly sheath is provided with optical fiber, and the butterfly sheath inside of optical fiber both sides is provided with the reinforcement that is parallel to each other; Be provided with filling material in the space between butterfly optical cable unit outer wall and the oversheath inwall.
The junction of described adjacent two butterfly sheaths is provided with out the stripping point.
Described oversheath, messenger wire sheath, connecting portion and butterfly sheath adopt PVC or LSZH to make.
Described reinforcement adopts glass fibre to make.
Described filling material is cable cream.
The present invention has the following advantages:
1, oversheath is provided with messenger wire, and integrated have stronger stretch-proof performance from bearing structure, when laying, does not need to draw in addition a more independent messenger wire, has good laying property.
2, adopt this optical cable can conveniently implement the built on stilts of optical cable and lay, reduce built on stilts density, reduce fiber cable laying cost and labour intensity, improve fiber cable laying efficient, lay simple to operate, time saving and energy saving.
3, the reinforcement that is parallel to each other is set in the butterfly sheath, it is stressed evenly to lay rear cable, significantly improves the mechanical property of butterfly optical cable.
