The present invention relates to fiber-optic connector, tip, designed for use in fiber-optic connector and method of manufacturing the tip. In particular, the present invention relates to fiber-optic connector, intended for precise alignment relative position of the cores of optical fibers and connecting them with each other by inserting optical fibers in supporting cylindrical tips, tip, designed for use in fiber-optic connector and method of manufacturing the tip. The present invention relates also to a device, the supporting wire element, intended for use in the manufacture of the tip.

The LEVEL of TECHNOLOGY

In recent years, electric cables for telephone lines around the world give way to the fiber-optic cables. Optical fiber is used not only in telephone optical communication. The optical fiber also finds wide application in optical devices, equipment, LANs (local area networks) and various optical systems. In optical communication systems use known methods of connecting optical fibers, including the way of permanent connection based on the use of splavki or mechanical splicing, and the way the split connection, based on the use of fiber-optic connector. For the application of fiber-optical connector according to the latest way you want, so you can easily perform connection and disconnection and to fiber optic connector has been sustainable to the environment. In addition, to create an optical communication system with high bandwidth, performing long-range communications, it is necessary to reduce losses in the connection, provide a fiber optic connector, and apply processing non-reflective substance to stabilize the transmittance of the laser radiation.

Typically, as shown in figure 1 (C), fiber optic connector comprises a tubular elements 1A and 1b (hereinafter referred to as "tips"), has a cross-sectional circle, designed for mounting optical fibers 40A, 40b with a diameter of about 0.13 mm in certain positions relative to the axis specified with high precision, the alignment section 42, in which the nozzles 1a, 1b may be located adjacent to each other. Consider, for example, the tip of the cylindrical form shown in figure 1 (A), made of a ceramic material based on zirconium dioxide or similar material. Tip 1 shown in figure 1 (A), is a tip for the accommodation is single core. For example, in the handpiece 1 has a through hole 2 exactly circular cross section φ=0.126 mm, passing in the longitudinal direction along the axis of the cylinder with a length of about 8 mm Tip G, shown in figure 1 (B)represents a tip for two hearts. In the handpiece 1' has two through holes 2A, 2b, through which you can skip two optical fibers.

For the manufacture of the tip shown in figure 1 (A) use the following method. First, the source material which is a mixture of powdered Zirconia and resin, molded, giving it the shape of a cylinder, using, for example, molds for injection molding or extrusion. Thereafter, the molded product is calcined at a temperature of about 500°to decompose resinous component, and then calcined at a high temperature of about 1200°C. In the obtained cylindrical sintered product has a through hole in which the insert element diamond polishing pads having a linear configuration, in order to accurately adjust the inner diameter of the through hole. Finally, the outer part of the cylindrical product is subjected to mechanical treatment relative to the center of the inner hole for finishing tip to give it exactly round shape.

According to the above is the method of molding, sintered molded product is slightly narrowed a result of firing, and therefore its internal diameter corresponds to the desired size. For this reason, the polishing process based on the use of diamond polishing, which is carried out after firing, is absolutely necessary processing stage. However, polishing is time consuming, requiring skill, which reduces performance. In addition, when the polishing process, it is not easy to achieve exactly the same internal diameter relative position in the direction of the axis of the inner hole of baked goods, such as heterogeneous attach the diamond to the linear polishing element. In addition, there is a problem of high cost of the equipment, due to the expense and wear and tear item of diamond polishing.

For the above-described injection molding or extrusion requires specialized and expensive machine to mold and shape. It should be noted that powdered zirconium dioxide, because of its exceptional hardness, have a significant abrasive effect on the machine for forming and shape, which greatly reduces their lifespan. Therefore, the surface of the machine for forming and forms should also be made of solid material is as. However, the cost of manufacturing such a specialized machine for molding and specialized forms increases. In addition, the use of burning at temperatures from 500 to 1200°results in high power consumption, which leads to the expenditure of energy source. Because of the high cost of manufacture of the tip with the use of the method described above, the cost of manufacturing optical fiber connector in which is placed the tip is also high.

In addition, there is the following problem. Although still primarily use the tip of a single core, depicted in figure 1 (A), gradually develops the need for tips to accommodate the two cores shown in figure 1 (B), and the tips to accommodate more than two cores. As for tips for placing two or more hearts, you can make sizes by polishing using a item of diamond polishing is extremely difficult. Tips for placement of three or more hearts to make practically impossible.

To connect with one another optical fiber with fiber optic connector establishes connection, in which the ends of the optical fibers are adjacent to each other, i.e. form the so-called physical contact (below oboznacheny "FC"), to reduce reflection losses at the connection point. In order to achieve a connection with FC carry out the following processing. The end surface of the ferrule is polished to obtain a convex spherical surface or a convex spherical surface with a bevel, or the end surface of the ferrule is polished to obtain a flat surface or beveled flat surface, together with the end of the optical fiber when the optical fiber is inserted into the tip. When using traditional tips, made of Zirconia or glass, there is a problem with the complexity of such a process.

In accordance with conventional technology, in order to place the handpiece in the fiber optic connector, you must first place the handpiece in the holder, and then, together with holder, set in a fiber-optical connector, since the holder allows you to rotate the tip, adjusting its position relative to the axis. In connection with the use of such holder the amount of detail fiber optic connector increases, which is also a problem.

The INVENTION

Considering the above problems inherent in the prior art, a first object of the present invention is the tip, the manufacturing method and device is on for its manufacture, to make the tip at low power consumption by using simple and inexpensive equipment, without having to use any expensive and specialized equipment, such as machines for molding and forms.

According to the first aspect of the present invention, a method of manufacturing a tip used for the optical connection in the curl, containing phases in which the precipitated metal by electroplating processes on at least one wire element for receiving product electrotype in the form of a rod without providing a layer of solder on the wire element, with at least one wire element has a diameter slightly greater than the diameter of the optical fiber, and pull or ekstragiruyut wire element of the product electrotype without the use of dilution and application of heat, causing deterioration of characteristics of the wire element. The inner diameter of the tip is determined by the outer diameter of the wire element, the precision of the inner diameter of the tip is determined by the accuracy of the outer diameter of the wire element, therefore, in the presence of the wire element, the cross section which repeats the cross-section of the optical fiber, and a width or diameter greater than the thickness of the optical fiber and which has a high accuracy, linearity and circularity, you can get a tip, characterized by exceptional precision of the inner diameter. In this regard, there is no need for polishing operations, which produced so far to ensure the dimensional accuracy of the inner diameter of the tip. After deposition on the wire metal element method is galvanoplastic wire element can be removed from the product electrotype by placing the product electrotype on Wednesday, dissolving only the wire element, or by extrusion or extrusion of the wire element from the product of the electrotype. Accordingly, it becomes possible to obtain a cylindrical metal tube, which has a through hole with a cross-section of the same shape as that of the wire element. It is desirable to use a wire element consisted of a wire element, the outer diameter of which does not exceed 0.2 mm, preferably not greater than 0,13 mm

For receiving the tip of the product electrotype to the product electrotype use mechanical handling, first cut into pieces of a certain length. The outer peripheral portion of the product electrotype can be cut around the center through hole, which is formed by the removal of the product electrotype wire element.

According to the method that meets the present invention, for example, if the wire element is made of aluminum or alloy thereof to remove the wire element of the product electrotype it is preferable to dissolve the wire element in an alkaline or acidic solution at the end of step electrotype. If the wire element is made of iron or alloy based on it, before stage electrotype pre is respectfully apply to the wire element processing for release forms, and at the end of step electrotype be removed from the product electrotype wire element, pulling or squeezing the wire element of the product electrotype.

Two wire element is positioned so that between the wire elements were placed two rods of the same diameter, which allows you to easily and precisely adjust the distance between the two wire elements. In a similar way it is possible to make the tip to accommodate three or more hearts, having three or more wire element parallel to each other and providing a uniform distance between them, for example, by using two or more studs.

According to the second aspect of the present invention, is provided with a metal head, the precision of the inner diameter of which is determined by the accuracy of the outer diameter of the wire element, and made way related to the first aspect.

According to a third aspect of the present invention, a handpiece designed for use when you connect the AI of the optical fibers, moreover, the tip is formed only of a metal material as a whole.

The metal tip that meets the present invention, it is possible to simply, inexpensively, and with high accuracy to produce, for example, by electroplating, in accordance with the present invention. In order to join together two optical fibers using fiber optic connector, which is the tip end of the tip should be polished together with the optical fiber to provide a flat interface or interface with FC. Polishing the tip meets the present invention is very simple because it is made of metal. The tip meets the present invention allows the operation of polishing with high-precision adjustment. This gives the possibility to perform high-quality docking with FC and to achieve low reflection losses at the interface of optical fibers.

At both ends of a tip that meets the present invention, there are openings through which may pass the optical fiber, these holes by machining, attached to the conical shape that allows you to use the tip as a coupling for mechanical splicing.

The tip may contain columnar section of the cavity, passing in the longitudinal direction of the handpiece, the first end of the handpiece may be the first hole, the diameter of which is equal to the diameter of the section of the cavity, and the second end of the handpiece may be the second hole, the diameter of which is larger than the diameter of the section of the cavity (see Fig). The section of the cavity may contain a first section of the cavity, the second section of the cavity, the diameter of which is larger than the diameter of the first section of the cavity, and a third section of the cavity of conical shape, connecting the first section of the cavity with the second section of the cavity. In this configuration, the region of the optical fiber, coated, is placed in the second section of the cavity, and the sheath of the optical fiber is placed in the first section of the cavity. Thus, the second section of the cavity plays the role of a traditional handpiece holder. The third section of the cavity facilitates the introduction sheath of the optical fiber in the first section of the cavity.

According to a third aspect of the present invention provides a fiber optic connector intended for connection of optical fibres, containing the tip, formed only of a metal material as a whole, and the housing for placement of the tip.

Two wire element in contact with the protrusions, for example, pressed against the protrusions, for example to the support pins located on the carrier plate opposite each other. Thus, the wire elements are arranged on both sides of the protrusions. Accordingly, the distance between the two wire elements with high precision regulated in accordance with the diameter of the supporting studs. To be able to set different distances between multiple internal holes in the tip to accommodate multiple cores, you can pre-prepare the supporting studs of different diameters, and the proper way to change the reference pins depending on the desired distance between the inner holes.

PREFERRED embodiments of the INVENTIONS

First of all, let us consider, with reference to figure 2, the device for manufacturing a tip according to the present invention, by electroplating. The device shown in figure 2, contains a bath 50 for electrotype, solution 3 for electrotype, tucked into the tub 50 for electrotype, and the anode 4 and the cathode 8, placed in the bath 50 for electrotype. Four of the anode 4 are arranged around the cathode based on 52 mounted on the bottom of the bath 50 for electrotype. As described below, the cathode 8 is installed on the host mounting the device 5 and is electrically connected to the wire element 9, stretched between the upper and lower ends of the bearing mounting fixture 5. Based on 52 provided air nozzle 6, arranged around a wire element 9 at intervals of 90°.

Solution 3 for electrotype choose depending on what kind of metal material is electro-deposition on the wire element 9, and the metal deposition is possible to use Nickel or alloy thereof of iron or alloy, copper or an alloy based, cobalt or an alloy based alloy based on tungsten and the metal in the dispersed state, consisting of small particles. As solution 3 for electrotype you can use the solution, the main component of which is an aqueous solution of sulpham Nickel, Nickel chloride, Nickel sulfate, sulpham iron, perborate iron pyrophosphate copper, copper sulfate, perborate copper, fertilitate copper, formetanate copper, alkanesulfonyl copper, cobalt sulfate, sodium tungstate, and the like, and a solution obtained by dispersing in the aforesaid solution of fine powder of silicon carbide, tungsten carbide, boron carbide, zirconium oxide, silicon nitride, aluminum oxide, diamond, etc. From the viewpoint of simplifying the process of electroplating processes, the reduction of stresses in the product electrotype, providing chemical resistance and ease of welding, it is most preferable to fill the tub, as the main component, sulpham Nickel.

The metal component of the solution for electrotype service is tons of material, the components of the product electrotype, i.e. the tip. As described below, the tip is subjected to polishing to ensure a FC when making connections. From the viewpoint of polishing to ensure FC, is particularly preferably used as a metal component, a Nickel-cobalt alloy.

The solution for electroplating processes can be filtered with a high speed in the bath for electroplating processes using a filter (not shown), the filtering accuracy of approximately 0.1-0.2 μm, and it can be heated so that its temperature can be adjusted in the proper temperature range, about 50±5°C. it is Preferable to periodically apply a treatment with activated carbon to remove organic impurities. Supplying electricity, it is desirable to provide a low current density of about 0.2 A/DM²to remove metal impurities, such as copper, from a solution for electrotype, who is in the bath, using coal as the anode and the corrugated sheet is made of iron coated with Nickel as the cathode.

The anode 4 is selected depending on the metal that is subjected to electrodeposition, which may be, for example, Nickel, iron, copper or cobalt. It is preferable to use the anode plate or spherical configuration of the AI. In the case of spherical electrodes can be used, for example, spheres, placed in a basket made of titanium, and cover them with a cover made from polyester.

Now, with reference to figure 3, let us consider in more detail the construction of the carrier mounting device 5. Figure 3 (A) shows a side view, and figure 3 (B) shows a view in section of the bottom plate 11, observed in the direction of the In-Century Bearing mounting device 5 includes an upper plate 10 and lower plate 11, connected to each other by four supporting posts 12 located between them. The top plate 10 and bottom plate 11 may be made of insulating material, such as polyvinyl chloride, polyamide, acetal resin, or polyethylene. Supporting rack 12 can be made of metal, for example stainless steel or titanium, or plastic. The top plate 10 and bottom plate 11 can be fastened to the supporting uprights by screws (not shown). In the Central part of the upper plate 10 includes a screw 13A of corrosion-resistant material acting as a cathode 8, and the screw 13A of corrosion-resistant material passes through the top plate 10. Screw 13A of corrosion-resistant material secures the first end 7a of the spring 7 made of stainless steel, on the lower surface of the upper plate 10. Similar is about, in the Central part of the bottom plate 11 there is a screw 13b made of corrosion-resistant material, and the screw 13b made of corrosion-resistant material passes through the bottom plate 11 and protrudes from the upper surface of the bottom plate 11. The screw 13b attached to the clamp 15, is made of plastic. As described above, in the bottom plate 11 in four places-drilled round holes 14 under the air nozzle. The first end of the wire element 9 is suspended at the second end 7b of the spring 7 made of stainless steel. The other end of the wire element 9 is clamped in the clamp 15, which provides the tension of the wire element 9 due to the elongation of the spring 7. When the wire element 9 is attached to the bearing mounting device 5 as described above, the wire element 9 is supported in the tub 50 for electrotype taut and upright.

Bearing mounting device 5, shown in figure 3, is a mounting device by which the electroforming to form the tip of a single core. In order by electroforming to form the tip to accommodate two hearts, can be used, for example, a carrier mounting device 5', the construction of which is depicted in figure 4. Mounting lighting fixtures is of 5', shown in figure 4, contains support elements 17, made of plastic, which are located in two positions between the top plate 10 and bottom plate 11. In the Central part of the supporting element 17 is embedded profilaktiniai element 18, is made of plastic, in two places which are drilled pores 19. The screws 13 made of corrosion-resistant material and clamps 15 are provided, respectively, in two places. To ensure the parallelism of the two wire elements 9 and a certain distance between them on a wire elements 9 supported between the supporting elements 17, provided by the elements 25 of the solder, arranged with certain intervals, for connecting wire elements 9. The design of the mounting device 5' is similar to the design of the mounting device 5, shown in figure 3, except for the above design features.

For the manufacture of the tip to accommodate three or more hearts, you can modify profilaktiniai element 18, in accordance with the number of wires, in the same way as in the mounting device 5', shown in figure 4, and, accordingly, to increase the number of screws 13 made of corrosion-resistant material and clamps 15. However, there are other ways to support wire elements is 9, different from the above-described method. For example, instead of springs, you can use another elastic member such as rubber or, for tensioning the wire to the bottom end can be loaded with cargo. For more precise adjustment of the distance between the two wire elements, it is preferable to use a carrier mounting device that meets the fourth variant implementation, described below.

In the manufacture of the tip to accommodate two or more cores, high accuracy is required observance of the sizes described above. Therefore, the cross section of the wire element 9 does not necessarily have the shape of a circle. For example, it is preferable to use a wire materials, cross-sections are shown in figure 5 (A)-(G)differ from the circle. In (A) shows the wire for the manufacture of the tip to accommodate two hearts, the cross section of which has the shape of an ellipse. The dotted line in the drawing correspond to the optical fibers, which can be held inside the tip, which is produced by electroforming using a wire element.

Figure 5 (B) shows a view in section of the wire element for the manufacture of the tip to accommodate the three of hearts, the cross section of which has the shape of a triangle with rounded corners. Figure 5 (C) is rendered view in section of the wire element for the manufacture of the tip to hold four hearts, the cross-section of which has the shape of a rectangle with rounded corners. Figure 5 (D) shows a view in section of the wire element for the manufacture of the tip to accommodate the five of hearts, the cross section of which has the shape of a Pentagon with rounded corners. Figure 5 (E) shows a view in section of the wire element for the manufacture of the tip to accommodate the six of hearts, the cross section of which has the shape of a hexagon with rounded corners. Figure 5 (F) shows a view in section of the wire element for the manufacture of the tip to accommodate the seven of hearts, the cross section of which has the form of a septangle with rounded corners. Figure 5 (G) shows a view in section of the wire element for the manufacture of the tip to accommodate the four of hearts, the cross section of which has an elongated shape. According to figure 5 (G), it is assumed that the optical fiber is denoted by dashed lines, are received within the tip in one line. Wire depicted in figure 5 (A)-(G) may have a cross-section without any rounded corners. Wire can be used instead of the wire element 9 shown in figure 1-4.

According to figure 2, through the openings of the air nozzles 6 are releasing a small amount of air to mix a solution of 3 for galvano the astika. However, for mixing the solution for 3 electrotype is not necessary to blow out the air, but you can apply other methods based on, for example, using a propeller stirrer, ultrasonic waves or ultrasonic vibrations. From the point of view of ensuring the linearity of the wire element 9 is particularly preferable to use a mixing ultrasonic wave.

As the wire element 9, it is preferable to select and use, for example, a metal wire made of iron or alloy on its basis, of aluminum or of an alloy based on, or copper or an alloy based on it, the same wire, covered with a thin layer of solder and plastic wire, made of nylon, polyester, Teflon, etc. In the case of using a plastic wire you need to create a conductive surface, depositing, for example, Nickel or silver, by the method of chemical recovery. It is preferable to use a conductive plastic. In this case, upon completion of the electrotype, passing an electric current through conductive plastic heat, you can easily release form to retrieve it from the product of the electrotype. The wire element 9 defines the inner diameter of the tip, produced by electroforming. Therefore, thickness, roundness and inanest wire must be maintained with high accuracy. Adjustment of the thickness, roundness and linearity of the wire can be accomplished by, for example, the method based on extrusion through the die, wire drawing or non-centered treatment. At present, there is, for example, corrosion-resistant wire with a diameter of 125 μm with a deviation in the range of about ±0.5 μm, which can be used to make corrosion-resistant wire element. In the case of stranded wire, the cross-sectional shape which differs from a circle, shown in figure 5, you can get the exact dimensions, for example by extrusion using a stamp.

Now consider the operation of forming the tubular element by electroforming using a device 100 for electrotype, shown in figure 2. The tub 50 for electrotype fill with solution 3 for electrotype, then between the anode 4 and the cathode serves 8 this DC voltage, providing a current density of from about 4 to 20 A/DM². By electrotyping for about 1 day at the above current density around the wire element 9 can increase product electrotype thickness or diameter of 3 mm At the completion of the electrotype bearing mounting device 5 is removed from the bath 50 and the wire element 9 is removed from the carrier mounting fixture is 5. The wire element 9 can be removed, for example by pulling it from the product electrotype or dissolving it heated alkaline or acidic water solution. In the case of a metal wire coated with solder, the metal wire can be pulled out, heating it.

Alternatively, the wire element 9 can also be derived from the product of the electrotype by extrusion. For this purpose, for example, the pin 22 of the cemented carbide and the guide 21, which is done through hole 21A, shown in Fig.6, setting the guide 21 in relation to the product 23 electrotype so that the through holes 21A, 23a connected with each other by passing through them studs 22 of the cemented carbide. Thus, the wire element 9 can be squeezed out of the product 23 electrotype pin 22 of the cemented carbide. Before carrying out this procedure, the end of the wire element 9 product 23 electrotype preferably slightly dilute with reagent.

A procedure in which a wire element 9 located in the centre of the product electrotype, pull, squeeze or dissolve the reagent is chosen depending on the material from which made the wire element 9. In General, if the wire element is poorly soluble reagent and the region which gives high tensile strength, it is preferable to use a process of extrusion or extrusion. If the wire element is readily soluble reagent, it is preferable to apply the dissolution. For example, if the wire element is made of iron or alloy based on it, you can perform the following procedure. Subjecting the wire element 9 processing for release forms, cover separate areas of the wire electrically insulating element 20, for example with vinyl tape as shown in Fig.7, and then perform the above step electrotype. When electrically insulating element 20 prepare the chin from the product of the electrotype to expose the wire element 9, as shown in Fig, the wire element 9 can be easily pulled out of the product 23 electrotype. When using a metal wire, which is deposited a layer of solder, and a plastic wire, subjected to precipitation by chemical recovery, the wire can be pulled as described above, without performing the processing for release forms. When using wire, covered with a layer of solder, the wire can be pulled out, heating her. When using the method of extrusion, it is preferable to use as the wire element 9 corrosion-resistant wire with a diameter of 0.126 mm and a length of 100 mm

If the wire element 9 is made, for example, aluminum or alloy thereof, copper or an alloy based on it, the method of removing by dissolution is more efficient because the wire element 9 is readily soluble in acidic or alkaline aqueous solution. Preferably used as the solvent of the solution strongly alkaline aqueous solution, which dissolves the aluminum or alloy based on it and almost does not affect the metal deposited by electroplating. In particular, the wire can be easily dissolved and removed with an effective heated to about 100±3°using a strongly alkaline aqueous solution consisting, for example, sodium hydroxide or potassium hydroxide with a concentration of about 5-10% weight/volume. It was established experimentally that aluminum wire length of 10 mm was successfully dissolved and removed in about 90 minutes. In this case there is no need to perform the extrusion. So no need to cover the wire insulating element, as shown in figure 1, before the implementation of the electrotype. It is enough to perform the electroplating on the entire surface of the wire element 9. In addition, it is not necessary to expose the wire element 9 processing for release forms.

The resulting product electrotype can be used as a tip, cutting the product into pieces of a certain is Lina, for example, using a torch with a fine blade. Note that the application of the method according to the present invention enables to maintain the inner diameter of the tip with extremely high accuracy. Accuracy is determined by the size deviation above the wire element 9. To improve the roundness of the outer diameter of the tip, it is preferable to perform the final machining of the outer peripheral part. Finish machining the outer peripheral portion can be performed by subjecting the outer peripheral portion of the cutting using CNC machines. Removing the wire element 9 by the method of dissolution, proceed to the next procedure. In other words, after the implementation of the electrotype, linear product electrotype cut into pieces of the desired length. After that, the wire element 9 is completely dissolved in an acidic or alkaline solution for education within the product electrotype through holes. Then, the outer peripheral part can be subjected to a finishing process, for example, by using a CNC machine. In this case, the stage of dissolution can be carried out after processing the outer peripheral part.

While a single one-piece optical fiber 40A is already embedded in each of the tips. Optical cable 120 can be attached, for example, to another optical cable, or another fiber optic connector through an adapter 140, shown in Fig.

ELEVENTH VARIANT IMPLEMENTATION

On Fig shows another variant implementation of the handpiece according to the present invention. The tip 150, shown in Fig, is a cylindrical, made of a Nickel-cobalt alloy is formed by electroplating. It's time 150A with a diameter of about 0.126 mm, designed to accommodate the optical fiber, passes through the axis of the cylinder. It's time 150A has a conical extension at one end and passes into the section 150b cavity with a diameter of 0.9 mm Optical fiber 40A inserted by section 150b of the cavity of the tip 150. Covered part 40 (for example, φ=0.9 mm) optical fiber 40A is also inserted into the section 150b of the cavity. Thus, the tip 150 functions as the tip 92 (92A, 92b) and the holder 106 of the tip (a, 106b), shown in Fig and 17. In the case of traditional tip, the center of the pores eccentric relative to the outer surface. Therefore, in order to avoid reflection losses holder rotates so that the position of the cores of the optical fibers relative to each other coincide. However, the tip is obtained by electroforming according to the present invention, is of extreme dimensional accuracy of the inner diameter. This allows not to use the holder. In other words, the tip shown in Fig, can be seen as the tip, combined with the holder.

Accordingly, the tip design is shown on Fig, can be placed in the body of the connector without the aid of the holder. Therefore, using the tip of this design, you can further simplify the design of fiber-optic connector.

The tip design is depicted in Fig, can be produced by electroforming using a wire element whose shape matches the shape of the pores 150A and sections 150, cavity, i.e. the wire element containing coaxial sections, one of which has managemetn in accordance with the sometimes 150A, and the other has a large diameter in accordance with sections 150b cavity.

However, this is only illustrative embodiments of, and specialists in this field is obvious various improvements and modifications without leaving the scope of the present invention. The above is an implementation option is an illustrative fiber optic connector, which is the tip of a single core. However, there is no need to remind you that it is possible to construct a fiber optic connector using the tip of a single core, the manufacture of which is provided above options implementation.

An explanation was given on the example of a case where the material of the tip is the objects of study were aluminum alloy or SUS. However, you can use any materials in the presence of which can be electroformed. As the fiber optic connector were considered random fiber optic connectors containing the tip, including, for example, connector type, connector, connectors, socket, combinations thereof, and combinations of two plugs and adapter, receivers and connectors, equipped with a fiber-optic cable.

Therefore, the present invention consists in the method of manufacturing the tip, ensuring low energy consumption and energy savings.

According to the present invention, through the use of the method of the electrotype, is a high-precision transfer sizes. No longer needed is here in the polished product electrotype on the grinding machine, and therefore, eliminates manual operation. Therefore, the scrap rate is reduced and productivity increases. In particular, the deviation of the size of the internal diameter of the resulting tip is determined by the dimensional accuracy of the wire element is used as a supporting material for electroplating processes. Accordingly, it is easier to adjust the dimensions of the product. Therefore, unlike traditional methods, which use the holder (capillary) to set the rotary position of the tip in the fiber optic connector when placing the tip in the fiber optic connector when using the handpiece according to the present invention, it is possible to exclude the use of such holder. Thus, the tip according to the present invention enables to simplify the construction of fiber-optic connector.

When using the traditional way was extremely difficult to get the size by polishing tips for hosting multiple cores, resulting in the production of tips to accommodate three or more hearts have been possible. However, the method according to the present invention, makes it easy to make such tips are essentially the same manner as the lugs to fit one heart the guilt.

When using the device electrotype, equipped with a bearing device according to the present invention, it is possible to easily and accurately produce tips for hosting multiple cores with low cost.
