Abstract
The invention discloses an improved central tube type optical cable which comprises an optical cable sheath (1). Two or more than two loose tubes (2) in different colors are parallelly arranged in the optical cable sheath (1), optical fibers (3) in different colors are arranged in each loose tube (2), first water-blocking substances (4) are filled in the loose tubes (2) which are longitudinally wrapped by a composite metal belt (5), second water-blocking substances (6) are filled among the loose tubes (2) and the composite metal belt (5), and reinforcers (7) are parallelly arranged in the optical cable sheath (1). The improved central tube type optical cable solves the technical problems during production of central tube type optical cables with more than 12 cores in the prior art, and is simple in structure and convenient to manufacture.
Description
Technical field
The present invention relates to the communications optical cable field, be specifically related to a kind of improved central tube type optical cable.
Background technology
Central-beam tube type fiber optic cable under the prior art condition, its structure are that the center is a loose sleeve pipe, and optical fiber all is arranged in this loose sleeve pipe, and stiffener and sheath are positioned at the outside of loose sleeve pipe.The optical cable of this structure is generally below 12 cores.Existing central-beam tube type fiber optic cable is distinguished after will producing and must using the bundle yarn of different colours to wrap up to optical fiber more than 12 cores, so production technology and production equipment has been proposed very high requirement, generally is difficult to reach.The application prior art is produced the above central-beam tube type fiber optic cable of 12 cores and is very easily caused raw-material waste and economic loss.
Summary of the invention
The technical matters that (one) will solve
The technical problem to be solved in the present invention is how to utilize existing common production device fabrication to make the above central tubular communications optical cable of 12 cores.
(2) technical scheme
For solving the problems of the technologies described above, a kind of improved central tube type optical cable is proposed, comprise cable jacket, the loose sleeve pipe of two or two above different colours is arranged in parallel in described cable jacket, be furnished with the optical fiber of different colours in each described loose sleeve pipe, in each described loose sleeve pipe, be filled with first material that blocks water, each loose sleeve pipe vertically wraps up by metal compound belt, be filled with second material that blocks water between described loose sleeve pipe and described metal compound belt, reinforcement is arranged in parallel in described cable jacket.
Preferably, described cable jacket is the black polyethylene sheath.
Preferably, described loose sleeve pipe adopts PBT (polybutylene terephthalate) material or MODIFIED PP (acrylic plastering) material to make.
Preferably, described first block water material for filling optical fiber cream or water blocking yarn.
Preferably, described metal compound belt is composite steel-plastic belt or aluminium-plastic tape.
Preferably, described reinforcement is the phosphatization steel wire.
Preferably, described reinforcement is the even number root, and arranges in pairs.
(3) beneficial effect
Loose sleeve pipe in the improved central tube type optical cable of the present invention becomes state of nature to distribute, and has saved the stranded bundle yarn link of layer-stranding cable, has shortened the production cycle, has saved starting material, obtains economical and temporal doulbe-sides' victory.Adopt two or more loose sleeve pipes to replace single loose sleeve pipe of the prior art, make the production that realizes the above Multi-core number central tube type optical cable of 12 cores more oversimplify convenient purification.Cancelled the complicated production technique that reaches the purpose of distinguishing optical fiber in the present technology with the bundle yarn wrapping optical fiber of different colours, utilized existing common production equipment to realize very simply producing and being easy to color separation, convenient construction uses.
Description of drawings
Fig. 1 is the structural representation according to the improved central tube type optical cable of embodiment of the present invention.
Wherein, 1: cable jacket; 2: loose sleeve pipe; 3: optical fiber; 4: the first materials that block water; 5: metal compound belt; 6: the second materials that block water; 7: reinforcement.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done into a detailed description.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, embodiment of the present invention provides a kind of improved central tube type optical cable, comprise cable jacket 1, the loose sleeve pipe 2 of two or two above different colours is arranged in parallel in cable jacket 1, be furnished with the optical fiber 3 of different colours in each loose sleeve pipe 2, be filled with first material 4 that blocks water in each loose sleeve pipe 2, each loose sleeve pipe 2 vertically wraps up by metal compound belt 5, be filled with second material 6 that blocks water between loose sleeve pipe 2 and metal compound belt 5, reinforcement 7 is arranged in parallel in cable jacket 1.
The characteristics of embodiment of the present invention maximum are the loose sleeve pipes 2 that the center of cable configuration is placed 2 and above different colours at least, and each loose sleeve pipe becomes state of nature to be distributed in the cable configuration center.Can adopt two kinds of modes that block water in the pine sleeve pipe 2, first kind of way is to take the most general existing technology, fills second material that blocks water in each loose sleeve pipe, and second material that blocks water is generally optical fiber cream; The second way is to adopt the dry type stop water, fills other first materials that blocks water in loose sleeve pipe the inside, usually adopts water blocking yarn.Every loose sleeve pipe 2 inside can comprise the optical fiber 3 of the different colours of 1～12 core.The color of pine sleeve pipe 2 is different, and at the outside of loose sleeve pipe 2 double plastic-coated metal compound belt 5, metal compound belt 5 can be selected for example composite steel-plastic belt or aluminum plastic composite belt longitudinal bag.Gap-fill second between metal compound belt 5 and the loose sleeve pipe 2 blocks water material 6 to guarantee compactness and the longitudinal water-blocking characteristic of optical cable, and the interpolation of composite band has increased anti-extrusion ability and the waterproof and dampproof ability of optical cable.Composite band extrudes the cable jacket 1 of black polyethylene (PE) outward, parallel at least placement two reinforcements 7 in cable jacket 1, and reinforcement 7 can be phosphatization steel wire or other materials, reaches requirement with the tensile strength that guarantees optical cable.
Loose sleeve pipe in the improved central tube type optical cable light of the present invention becomes state of nature to distribute, and has saved the stranded bundle yarn link of layer-stranding cable, has shortened the production cycle, has saved starting material, obtains economical and temporal doulbe-sides' victory.Adopt two or more loose sleeve pipes to replace single loose sleeve pipe of the prior art, make the production that realizes the above Multi-core number central-beam tube type fiber optic cable of 12 cores more oversimplify convenient purification.Cancelled the complicated production technique that reaches the purpose of distinguishing optical fiber in the present technology with the bundle yarn wrapping optical fiber of different colours, utilized existing common production equipment to realize very simply producing and being easy to color separation, convenient construction uses.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
