Abstract
The invention provides a method for producing long-distance transmission optical cables made of manganese and cupronickel special alloy. A preformed rod made of the manganese and cupronickel special alloy is subjected to high-speed wiredrawing and becomes a fiber core of an optical fiber. The fiber core is subjected to coating and cladding to obtain the optical fiber with the depletion rate of less than 3dB/km. The optical fiber with the depletion rate of less than 3dB/km reaches the international leading level of the manganese and cupronickel alloy optical fiber. The optical cable made of the manganese and cupronickel special alloy is an insulator material, has strong immunity on electromagnetic interference in the process of transmitting signals, and is free from natural thunder interference and interference of artificially released electromagnetism. Moreover, the optical cable made of the manganese and cupronickel special alloy is thin in wire diameter, light in weight, flexible, small in occupied space, little in pollution, high in electrical conductivity, corrosion-resistant, heat-resistant, simple in technological process, long in service life and wide in application range. Therefore, products developed through adoption of the method not only can be applied to main communication lines, but also can be applied to an electric power telecommunication control system for industrial monitoring and control. The application range of the optical cables is substantially expanded.
Description
Technical field
The present invention relates to a kind of production method of digital fiber cable, the long Distance Transmission production method of digital fiber cable that especially relates to a kind of manganese, copper-nickel alloy special alloy.
Background technology
At present, in the power communication industry, that what adopt is pure silica core is more for general digital fiber cable, and quartz glass optical fiber is little with its decay, the bandwidth advantages of higher is used as at a distance, the optical transmission medium of capacity common network greatly.Quartz glass optical fiber is high because of its material purity, it is complicated to make, not anti-bending and extruding, continuously the drawbacks limit such as difficulty the compound advantage of low-voltage power cable, when having restricted its short distance optical fiber access as a large amount of utilizations of compound transmission medium.No matter the present far and near and broadband demand of communication distance on market and in the communication network planning design, generally take special-purpose silica fibre to transmit light signal, cause in the short distance situation problems such as communications cost is high, excessive the enforcements inconvenience of cost (especially for indoor employing silica fibre connection).This has just required a kind of medium to make cost relatively cheap, and function is relatively powerful, passage is more, the light switching is flexible, and has higher broadband rich, just optical fiber is had higher requirement in this case.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of long Distance Transmission digital fiber cable, and cost is relatively cheap, function is relatively powerful, passage is more, the light switching is relatively flexible.
For achieving the above object, the present invention solves the scheme that its technical matters adopts: the long Distance Transmission of a kind of manganese, copper-nickel alloy special alloy is with the production method of digital fiber cable, it is characterized in that, described manganese, copper-nickel alloy special alloy fibre core are that the new element that adds in Mn copper-nickel alloy is manganese and nickel, the prefabricated rods that obtains is through becoming the fibre core of optical fiber after high-speed wire-drawing, and manganese and the suitable proportional range of nickel are manganese Mn (1% ~ 9%) and nickel (40% ~ 44%).
A kind of long Distance Transmission of making described manganese, copper-nickel alloy special alloy production method of digital fiber cable, its step is as follows:
Step 1: the manufacturing of special alloy fiber core: than the fibre core of general silica fibre, this technique has increased the treatment process of alloy bar material, as cold treatment process and multiple tracks Technologies for Heating Processing such as extrusion, cold-drawns, can guarantee that so on the one hand the variation of tissue can not occur the special alloy prefabricated rods that obtains in follow-up process, and lay the foundation for follow-up change in size, guaranteed that by cold and hot processing in earlier stage the deformation of subsequent treatment is controlled;
Step 2: prefabricated rods is carried out wire drawing: although basic technology is identical with general drawing optical fibers link, all adopted the pattern of two-way reinforcing wire drawing in high temperature furnace, the material in conjunction with the prefabricated rods of my company has two places significantly to innovate on technique.One is because prefabricated rods is that alloy and pliability are good, so my company adopted the pattern of high-speed wire-drawing in drawing process, has reached the flank speed of 380 meters of per minutes, and in conjunction with the automatic rotation take-up reel, speed of production has reached the decades of times of silica fibre.In addition, inner structure and warm area that my company has also improved fiber drawing furnace distribute, make burner hearth inside produce the directed flow of air-flow, act on the prefabricated rods surface that is stretched, reducing the deposition of pollution object in drawing process adheres to, and this air current flow and warm area distribute and also help to produce desirable prefabricated rods and become the neck shape, thereby guarantee normally carrying out of wire drawing process;
Step 3: the coating of optical fiber: my company improves original technique that applies at a slow speed, still is combined with the wire drawing link, adopts the bare fibre core body after being out of shape to pass through at a high speed the technique that is coated with feed liquid.The dope viscosity difference that temperature difference on the bare fibre core that adopts this technique to take full advantage of to enter paint can causes, thus coating is produced from flowing, guarantee to apply on the bare fibre core surface the stable of liquid level;
Step 4: the dyeing of optical fiber: the whole chromatogram of application standard identifies, and requires high temperature not fade and does not move;
Step 5: secondary extrusion molding: my company has adopted unique gel implantttion technique.General technique is to get final product inserting through the optical fiber core that applies in the plastic casing of corresponding secondary extrusion moulding, but present technique is that gel is injected in the cage walls that is inserted with optical fiber core, alleviate with this stress that produces in follow-up stranded link on optical fiber, thereby improve pliability and the angularity of the optical fiber of final molding, expanded the range of application of optical fiber;
Step 6: stranded: the optical fiber that several extrusion moldings are good with strengthen the unit and twist together;
Step 7: add protective sleeve: the use laid condition different according to optical fiber, fibre core adds different sheaths outward, to satisfy under different condition the mechanical protection with optical fiber.
beneficial effect of the present invention is: the prefabricated rods that the manganese-copper special alloy is made is through becoming the fibre core of optical fiber after high-speed wire-drawing, the proportion of goods damageds of the optical fiber that obtains after process coating and coating again are less than 3dB/km, reached the top standard of Mn copper-nickel alloy optical fiber in the world, and the optical cable that the manganese-copper special alloy is made is insulating material, when transmitting, signal has extremely strong immunity for electromagnetic interference (EMI), not disturbed by natural thunder and lightning and the artificial electromagnetic interference (EMI) that discharges, its wire diameter is thin in addition, lightweight, soft, institute takes up space little, meet wire diameter and mechanics and the electric property technical requirement of client's needs, pollute simultaneously little, conductance is high, corrosion-resistant, high temperature resistant, technological process is simple, long service life and applied range.The product of developing so not only can be applied in the basic routing line of communication, can also be applied in the power communication control system, carries out industry monitoring, control, and range of application is significantly expanded.
