Abstract
A soft optical cable for wiring, which comprises metal detecting wires, consists of a tightly wrapping and protecting layer (3), an aramid fiber reinforcing layer (4) and an outer sheath layer (5), which wrap a cable (2). The metal detecting wires (1) are arranged inside the outer sheath layer (5) and the aramid fiber reinforcing layer (4) in parallel with the cable. An optical cable or a plurality of cables is provided. The metal detecting wires are one or a plurality of bare copper wires, silver-plated copper wires, tin-plated copper wires, aluminum wires or other well-conductive metal wires, and each metal detecting wire is provided with one or a plurality of cords. The utility model is widely used as the soft optical cable for wiring in a communication equipment room. The advantage of the utility model is that the cable can quickly find and correctly judge the fiber-broken cable, quickly judge the malfunctioning cable, and manage and dispatch the whole wiring system to operate normally, so the improving working efficiency is promoted..
Description
Affiliated technical field
The utility model relates to a kind of communications optical cable, especially a kind of flexible optical cable that contains the metal detection line.
Background technology
Be used at present between the communications equipment room frame and frame in distribution flexible optical cable tail optical fiber in all do not have the metal detection line, be a kind of full optical element.The joint length of these cables is all shorter, be generally several meters to tens meters, yet quantity is a lot.For safety and attractive in appearance, these cables generally band together, and are disconnected fine if a cable wherein takes place, and can only detect with the optics instrument and judge.Because length is short, optical time domain reflectometer commonly used can't be differentiated, and must come light path with light source and two instrument of light power meter, and workload is huge, and efficient is extremely low.If two or two disconnected fibres of above cables generation are arranged, resolve fine cable even find out, can't find out disconnected fine two ends fast end to end, often to open bounding wire and rejudge, tie up installation then again, very inconvenient.
Summary of the invention
In order to overcome the difficult problem that the hundreds of thousands of bundled cable inconvenience of existing communication machine room determine disconnected fine optical cable, the utility model provides a kind of distribution flexible optical cable that contains the metal detection line, make its method with electricity judge in the bundled cable every cable end to end, whole distributing system is managed and dispatched to the failure judgement cable also fast.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of distribution flexible optical cable that contains the metal detection line is made up of optical fiber, hard-pressed bale sheath, plain conductor, aramid fiber enhancement Layer and external sheath layer, it is characterized in that optical fiber from inside to outside coats hard-pressed bale sheath, aramid fiber enhancement Layer and external sheath layer outward successively, has the metal detection line with the optical fiber parallel lay-up in the aramid fiber enhancement Layer in oversheath.The above-mentioned described tightly packaged fiber number that is coated in the interior aramid fiber enhancement Layer of external sheath layer can be single or many; The metal wire that above-mentioned described metal detection line is bare copper wire, silver-coated copper wire, tinned wird, aluminum steel or other good conductive, the radical of this metal wire is single or many, every is detected metal wire is sub-thread or multiply.
The beneficial effects of the utility model are add the metal detection line in the distribution flexible optical cable after, can judge in the bundled cable every cable quickly and easily end to end with electrical method, failure judgement cable fast, and management, the whole distributing system of scheduling normally move.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the flexible optical cable cross-sectional view that the utility model contains single core metal detection line.
Fig. 2 is the flexible optical cable cross-sectional view that the utility model contains twin-core metal detection line.
In Fig. 1 one Fig. 2: 1. metal detection line, 2. optical fiber, 3. hard-pressed bale sheath, 4. aramid fiber enhancement Layer, 5. external sheath layer.
Embodiment
A kind of distribution flexible optical cable that contains the metal detection line is from inside to outside to coat hard-pressed bale sheath (3), aramid fiber enhancement Layer (4) and external sheath layer (5) successively to constitute outside optical fiber (2), be arranged with metal detection line (1) in parallel with optical fiber (2) in the aramid fiber enhancement Layer (4) in external sheath layer (5), the above-mentioned described tightly packaged fiber number that is coated in the aramid fiber enhancement Layer (4) is single or many; Above-mentioned described metal detection line (1) is the metal wire of bare copper wire, silver-coated copper wire, tinned wird, aluminum steel or other good conductive; The radical of above-mentioned described metal detection line is single or many, and the number of share of stock of every metal detection line is sub-thread or multiply.
Claims (4)
1. a distribution flexible optical cable that contains the metal detection line is made up of metal detection line (1), optical fiber (2), hard-pressed bale sheath (3), aramid fiber enhancement Layer (4) and external sheath layer (5), it is characterized in that optical fiber (2) outer from inside to outside outsourcing hard-pressed bale sheath (3), aramid fiber enhancement Layer (4) and external sheath layer (5) successively, in the aramid fiber enhancement Layer (4) of external sheath layer (5) inboard, be arranged with metal detection line (1) in parallel with optical fiber (2).
2. the distribution flexible optical cable that contains the metal detection line according to claim 1 is characterized in that above-mentioned described tightly packaged fiber (2) number that is coated in the aramid fiber enhancement Layer (4) is single or many.
3. the distribution flexible optical cable that contains the metal detection line according to claim 1 is characterized in that above-mentioned described metal detection line (1) is the metal wire of bare copper wire, silver-coated copper wire, tinned wird, aluminum steel or other good conductive.
