Abstract
The invention discloses a butterfly self-support type sensing cable. The butterfly self-support type sensing cable comprises an outer protective sheath (3), reinforcing members (2) and sensing optical fiber (1). The sensing optical fiber (1) comprises a PBT (polybutylece terephthalate) pipe layer (4), a waterproof layer (5), an adhesion layer (6) and a fiber core (7). The inside of the outer protective sheath (3) is provided with the sensing optical fiber (1) and the reinforcing members (2), and the axises of the sensing optical fiber and a pair of the reinforcing members (2) are on the same plane. The cross section of the butterfly self-support type sensing cable is in a butterfly shape, thereby effectively preventing parasites from living in the concave surface of a traditional optical cable and avoiding ponding corrosion of rainwater; meanwhile, the sensing optical fiber is arranged at the portion with the smallest thickness of the outer protective sheath, accordingly the sensing performance of the sensing fiber to temperature and pressure is enhanced, and further the stability of the optical fiber during transmission can be improved.
Description
Technical field
The present invention relates to a kind of self-bearing type sensing optic cable of communications optical cable technology, particularly a kind of butterfly.
Background technology
The FTTH network enters the phase of speeding up the construction, economy and the speed of for FTTH, building, and the optical cable and the access way thereof that are applied to FTTH present the characteristics that are different from arterial grid, as have microminiaturization, are easy to span centre branch, the optical cable of the characteristics such as dry type.Yet the common self-bearing type butterfly leading in cable of the general employing of traditional indoor optical cable, sprung parts separates at the place of registering one's residence with the light unit, and fiber unit is directly registered one's residence, eliminated the switching of indoor and outdoor optical cable, while laying, without setting up messenger wire and hook, operating efficiency is high, and expense is low.But traditional self-support cable is because oversheath is too thick, and sensitivity is very low, be difficult to adapt to the use under rugged surroundings.
Chinese Patent Application No.: CN201220528202 discloses a kind of self-bearing type leading in cable, comprise FRP center strengthening core, some single core butterfly optical fiber, waterstop, compound aluminium strip, multiply steel strand wires and pe sheath, described some single core butterfly optical fiber is distributed in strengthening core outer ring, described FRP center, the described some single core butterfly optical fiber of described waterstop parcel, described compound aluminium strip is located at described waterstop outer ring, described multiply steel strand wires are positioned at described compound aluminium strip top, described pe sheath is wrapped in outside described compound aluminium strip and multiply steel strand wires, this optical cable can conveniently be implemented the built on stilts of optical cable and lay, reduce built on stilts density, reduce fiber cable laying cost and labour intensity, but this optical cable is too poor to the perception of external environment.
Chinese Patent Application No.: CN201210507982 discloses a kind of tree-shaped sensing optic cable, comprise the high index of refraction fibre core that low-refraction integument and Duo Gen link together, the many high index of refraction fibre cores that link together comprise that main fiber fibre core and Duo Gen prop up fiber core, and main fiber fibre core and a fiber core need to be tree-shaped welding at certain node location according to application.This optical cable sensing optic cable does not need another oil (gas) filling device while being applied to multiple branch circuit, save optical cable, and comes to compare along separate routes with coupling mechanism or shunt, and loss and the additional interference of energy are all very little, but this optical cable tensile is stretched poor performance, is not suitable for built on stilts laying.
Chinese Patent Application No.: CN201220304442 discloses a kind of Combined type sensing optical cable, comprise cable sleeve and some single-core line cores, the single-core line core is annular arrangement, described cable sleeve is wrapped in single-core line core bundle outward, in addition, also be provided with one deck aramid fiber enhancement Layer for strengthening optical cable between sleeve pipe and single-core line core bundle, simultaneously, skin at every single-core line core also is enclosed with single core sleeve, and also be filled with water-proof plaster oil between single core sleeve and cable sleeve, such optical cable is easy to process can effectively be protected the optical cable cable, but this optical cable sensing capabilities is poor, effectively the temperature and pressure in the perception external world changes.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of self-bearing type sensing optic cable of butterfly is provided, design novel butterfly structure, avoided traditional mosquito to live away from home in the optical cable concave surface, sensor fibre is designed in oversheath wall thickness thinnest part simultaneously, strengthened the sensitive property of sensor fibre to temperature and pressure.
The objective of the invention is to be achieved through the following technical solutions: a kind of self-bearing type sensor fibre of butterfly, it comprises oversheath, reinforcement and sensor fibre, the sensor fibre ecto-entad is followed successively by PBT pipe layer, material water-proof material layer, adhesive linkage and fibre core, oversheath inside is provided with sensor fibre and reinforcement, and the axial line of described sensor fibre and pair of reinforcing pieces is positioned on same level.
The low-smoke halogen-free polyolefin protective cover material that described oversheath is anti-electric trace.
Described reinforcement is two parallel FRP material reinforcements.
Described adhesive linkage material comprises epoxy resin.
The present invention has following several large advantage:
1. optical cable adopts butterfly structure, has effectively avoided parasite to live away from home in traditional sensing optic cable concave surface, has also avoided the long-pending low-lying area of concave surface rainwater to cause corrosion;
2. sensor fibre is arranged at oversheath wall thickness thinnest part, has strengthened the sensitivity of sensor fibre to the temperature and pressure perception, makes optical fiber more stable in transmitting procedure;
3. optical cable also adopts two FRP reinforcements, and the axle center of reinforcement and sensor fibre be in same level, has strengthened that optical cable tensile is stretched, flattened, bending and the performance vibrated;
4. the butterfly structure that cable outer sheath adopts, avoided optical fiber unbalance stress everywhere, slackened the impact of oversheath on optical fiber sensitivity.
The accompanying drawing explanation
