Abstract
The invention discloses a dual self-holding optical fiber ribbon type wiring optical cable. The dual self-holding optical fiber ribbon type wiring optical cable comprises an optical fiber ribbon, reinforcement members, messenger wires and an oversheath. The wiring optical cable is symmetrical on the left and on the right; the optical fiber ribbon is disposed at the center of the wiring optical cable; the two messenger wires are respectively disposed at the left end and the right end of the wiring optical cable; the two reinforcement members are respectively disposed between the optical fiber ribbon and the corresponding messenger wires; and the oversheath is disposed at the peripheral side of the wiring optical cable. The wiring optical cable provided by the invention is large in cable core number, small in dimension and high in tensile strength, and can be applied to machine room wiring or fiber to the premise of indoor and outdoor buildings.
Description
Technical field
The present invention relates to a kind of wiring optical cable, be specifically related to a kind of double self-holding type optical fiber belt wiring optical cable.
Background technology
Along with 4G, the construction of cloud computing center, and Internet enterprises is pursued faster, computer room construction demand higher, more, the fiber capacity of machine room is increasing, but space is fairly limited, simultaneously for adapting to current machine room and the batch construction needs of residential quarters, Cable Core Number is required large core number, but cable size is the least.Wiring optical cable many employings branched cable of existing machine room or pencil optical cable, it is impossible to meet demand.In residential quarters, owing to community number, unit building are more, can not lead to below each unit building by outdoor optical cable, need to utilize wiring optical cable to be introduced to unit building in optical fiber distributing box from fiber box by outdoor optical cable, in fiber box, when outdoor optical cable and wiring optical cable welding, the light cell mesh of wiring optical cable is easily because under tension causes fibre loss abnormal.
Summary of the invention
The invention aims to solve defect present in prior art, it is provided that a kind of double self-holding type optical fiber belt wiring optical cables, this wiring optical cable includes fibre ribbon, reinforcement, messenger wire and oversheath；Wiring optical cable is symmetrical；Fibre ribbon is positioned at the center of wiring optical cable；Messenger wire is two, lays respectively at the two ends, left and right of wiring optical cable；Reinforcement is two, lays respectively between fibre ribbon and the messenger wire of correspondence；Oversheath is positioned at the outer circumferential side of wiring optical cable.
The cross section of wiring optical cable of the present invention is butterfly-type, including rectangular central portion and rounded ends；Rounded ends is positioned at rectangular central portion both sides, inside sets above-mentioned messenger wire；Fibre ribbon and reinforcement is set in rectangular central portion；It is connected by oversheath between rectangular central portion and rounded ends；Oversheath is provided with groove in the junction of rectangular central portion and rounded ends.
Wherein, messenger wire uses single round steel wire or steel strand wires；Reinforcement uses G-FRP(Glass Fiber Reinforced Plastic Rods, fiberglass reinforced plastics, is commonly called as fiberglass) or finer wire.
Fibre ribbon uses stacked strips structure, and core number is 4-288.
The cross sectional dimensions of the rectangular central portion of above-mentioned wiring optical cable is 7mm × 9mm；A diameter of 7mm of rounded ends.
The present invention has the advantage that compared to existing technology
1, present invention type optical fiber belt wiring optical cable of controlling oneself utilizes two messenger wires, common or each serve as drawing-resistant function, and the protection to optical fiber is more preferable.
2, middle part fibre ribbon uses stacked strips structure, and the design meeting core number requires demand, it is possible to by changing mould, and the most large-sized reserved endoporus, at middle superposition correspondence core number；Normally core number can meet and ensure quality between 4 core-288 cores.
3, middle part fibre ribbon and two ends messenger wire use dual-cavity design; the sheath of light cell mesh can be torn during construction easily from any side, take out required optical fiber, draw and connect use; the messenger wire of opposite side can ensure that the intensity of optical cable is unaffected, plays a very good protection optical fiber；And use double self-holding type design, and it is suitable for built on stilts use, wherein a self-holding messenger wire can be used to suspension joint box, another root cuts off welding, fixing use, more convenient, it is not necessary to be put into by optical cable on the ground, hang again after welding is good in making the return trip empty, improve the convenience of efficiency of construction and operation.
4, mid portion uses two thin reinforcements, after messenger wire separates, it is ensured that the intensity of middle light cell mesh, and joint riveting can be easy to when welding or quick connector, make do not produce dislocation between joint and optical fiber or move, it is ensured that the quality of joint and the reliability of transmission.
5, use oversheath to have outstanding aging resistance and uvioresistant performance, prevent the problems of crack after outdoor long-time sun exposure, relatively good to fiber optic protection.
6, wiring optical cable core number of the present invention is big, size is little, and tensile strength is high, can be used as machine room wiring or indoor and outdoor building fiber entering household.
Accompanying drawing explanation
Fig. 1 is the structural representation of wiring optical cable of the present invention.
In figure, 1-fibre ribbon, 2-reinforcement, 3-messenger wire, 4-oversheath.
Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the double self-holding type optical fiber belt wiring optical cable of the present invention is a kind of butterfly-type optical cable, including rectangular central portion and rounded ends.The cross sectional dimensions of rectangular central portion is 7mm × 9mm, inside sets fibre ribbon 1 and reinforcement 2.Fibre ribbon 1 is light cell mesh, uses stacked strips structure, core number as required to change mould, and reserved adaptive endoporus, middle superposition correspondence core number (between 4 core-288 cores), to meet and to ensure quality.Reinforcement 2 uses two thin reinforcements, usually G-FRP or finer wire, it is located at the two ends of fibre ribbon 1, effect is after messenger wire separates, the intensity of light cell mesh in the middle of ensureing, and joint riveting can be easy to when welding or quick connector, make do not produce dislocation between joint and optical fiber or move, it is ensured that the quality of joint and the reliability of transmission.Rounded ends is two, lays respectively at rectangular central portion two ends, and cross-sectional diameter size is 7mm, inside sets messenger wire 3.Two messenger wires 3, use single round steel wire or steel strand wires to play drawing-resistant function, it is ensured that the tensile strength of product and the convenience of construction.The outer circumferential side of wiring optical cable is coated with oversheath 4, is protected optical fiber by oversheath 4.
When wiring optical cable of the present invention carries out welding, first when taking optical fiber, a wherein messenger wire can be cut off; tear the sheath of light unit; take out required optical fiber and carry out the constructions such as welding, and another root messenger wire can ensure that the intensity of cable is unaffected, plays a very good protection optical fiber；Secondly, this optical cable is also adaptable for built on stilts use, and during welding, connector box can be hung directly from one of them messenger wire, convenient, and operation sequence is succinct, need not be put into by optical cable on the ground, hangs in making the return trip empty again, improve the convenience of efficiency of construction and operation after welding is good.
