The technical problems to be solved in the utility model; provide a kind of submarine cable for optical fibres telecommunications. class wherein is installed as making light--the lead of-electronics repeater power supply usefulness; can protect optical fiber to avoid running in the operation of cloth cable impact; also because the interior tight of optical cable; no matter and the degree of depth of lay how, the convection cell static pressure can have extremely superior stability, and is simple in structure; weight saving, can easily realize between lead and lead and optical fiber and optical fiber and optical fiber between effective the butt joint.
It is to realize by following technical scheme that the utility model will solve above-mentioned technical matters:
A kind of submarine cable for optical fibres telecommunications, it includes the armouring and the plastics oversheath of stable mechanical performance, be packaged with in the sheath fibre bundle, for transmitted number of optical fiber with light--the lead of electronics repeater power supply, it is characterized in that: described armouring is an anti-twist rope that compacts, the secret fluid that is filled with in space between the silk of this rope, that is:
Be provided with bundle conductor and Duo Gen pipe between described rope and the plastics oversheath, be filled with fluid in the pipe, pine is allocated at least one optical fiber into simultaneously, and lead and pipe then spiral shell change the described rope of shape ground coiling; And in adjacent a pair of pipe, be inserted with a lead at least, pipe---lead assembly is coated with plastic layer, they are surrounded accordingly by the penetralia surface of self in the plastic layer diametrically, pipe--between-lead assembly and rope not by in the occupied space of plastic layer, be filled with fluid.
Each pipe is adjacent with two leads, and touches with latter's subsides.
The diameter of described lead is identical with the external diameter of described pipe.
Described pipe--between-lead subassembly and the rope in the space, between rope wires in the space filling with a kind of fluid.
Described fluid is viscosity or high-viscosity fluid.
The submarine cable for optical fibres telecommunications of said structure provided by the utility model; can protect optical fiber to avoid running in the operation of cloth cable impact; also because the interior tight of optical cable; no matter and the degree of depth of lay how; the convection cell static pressure can have extremely superior stability; simple in structure, weight saving, can easily realize between lead and lead and optical fiber and optical fiber and optical fiber between effective the butt joint.The utility model is suitable for makes communication water bottom line cable.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the one-piece construction figure of the utility model embodiment.
Embodiment
Figure 1 shows that a kind of submarine cable for optical fibres telecommunications.Be a kind of armouring of forming by an anti-twist rope 1 that compacts, rope 1` is along radially in occupation of inner most position (size of rope 1 is wanted to withstand the cloth cable fully or to rise the traction stresses that is applied in the cable operation, is to have the material that the material of the steady foot of high degree of mechanical such as steel, aromatic poly amide, charcoal fiber and other material make by counter stress to constitute).
The periphery helically of rope 1 is coiling lead 4 and plastics or the metal tube of being made by copper or aluminium 5, and they have formed a kind of periphery of protuberance.(spiral fashion winding lead 4 and pipe 5 can be closed or open spirality, that is to say the trend that lead 4 and pipe 5 can be spread coiled s shape or z shape)
Pine is allocated at least one optical fiber into and is filled with for example incompressible viscosity or the high-viscosity fluid 7 of silicone profit oil, vaseline and so in the pipe 5.
The diameter of lead 4 can be greater than or less than the external diameter of pipe; The diameter of lead 4 is preferably identical with the external diameter of pipe 5; Its wall thickness then can be according to these pipes are determined with the degree of incompressible fluid institute filling.Pipe 5 is with lead 4 contact that misplaces mutually, and rope 1 pastes to touch and form around the latter and swells periphery together: every pipe 5 is adjacent and touch between subsides wherein and with it with two leads.
As shown in FIG., have two leads 4 to be inserted in a pair of adjacent pipe 5, the number of lead wires of in fact inserting in a pair of adjacent pipe 5 can be arbitrarily, can equate with the right number of whole pipes.Every pipe will touch with two adjacent subsides of lead, thereby also plays supporting role for tube wall.
At pipe---on the protuberance periphery that the lead assembly forms a plastic layer 8 is arranged.This plastic layer can make by polyolefin or the Polyvinylchloride or the nylon etc. of extruded polyethylene and so on.
Can dispose the conventional anti-erosion protective layer that adopts in the subaqueous cable at the outermost layer of optical cable.
The inner surface that plastic layer 8 is asked along the footpath and the outmost surface radially of pipe 5 one leads 4 subassemblies are coupled, and clog this subassembly with the space between the rope 19 through this subassembly.
In optical cable of the present utility model, the direct current return wire of powering for light-electronics repeater is a seawater itself.The plastic layer 8 owing to the formation cable jacket was between lead 4 and played between the seawater of return wire effect this moment, and was subjected to the effect of dielectric stress.
In optical cable of the present utility model, make butt joint between optical fiber and optical fiber with by the used light-electronic relay of transmission signals between be connected, become more or less freely.
Pipe 5 is to adjoin each other with lead 4, any type of dislocation obstacle when this has just prevented to carry out above-mentioned two classes and connects, and the reliability that all these helps connecting, thereby also just improved the reliability of the optical cable of being formed on the whole.
When between the space of pipe 5---lead 4 these assemblys with the incompressible fluid filling after, just can simplify to greatest extent and being connected because of this measure of butt joint between optical fiber and optical fiber and repeater be convenient to remove a part of sheath or plastic layer 8 from optical cable, simultaneously this be again when connecting operation must do.
Containing the pipe of optical fiber can be correctly lay and stably in place around armouring, because lead 4 has been arranged, their diameter is preferably with the equating of these pipes-and do adjacent subsides with pipe and touch, after forming plastic layer 8 by extruding, just got rid of any may change of pipe 5 on arranging, correctly dispose these pipes and lead, help to simplify butt joint and optical fiber and light--being connected of-electronics repeater between optical fiber.
Optical cable of the present utility model is reduced to bottom line with weight. and be that maximum flexible is arranged simultaneously; Because in this optical cable innermost zone radially, dispose the dress of the stable mechanical performance of forming by the anti-twist rope that compacts, and the size of this rope being enough to resist cloth cable and the traction stresses that rises in the cable operation. this itself just makes optical cable possess the lightest weight as much as to say; In addition, the axis that constitutes the rope of cable armor is with the optical cable dead in line of representing the flexural center axis. the lead in the optical cable then touches with its subsides, the silk material and the above-mentioned lead that constitute rope just have from the presumable bee-line of optical cable central axis, make optical cable that maximum flexible arranged; Set lead 4 is placed in solid metal part on the rope 1 that compacts for some; adjacent with pipe 5 and paste and touch. this has just played supporting role to tube wall, at the cloth cable and/or rises in the cable operation. and protecting the optical fiber of these pipes and Qi Nei dress to avoid the shock effect (even at this moment also harmless) that optical cable itself unavoidably experiences around the armouring that stable mechanical performance is not set in the optical cable district that protects optical fiber.
