The technical field to which the invention relates.

[0002] the Present invention relates to curable emission is m coatings for optical fibers, coated with the aforementioned coating optical fibers and methods for producing optical fibers with coatings.

The level of technology

[0003] Optical fibers typically cover two or more radiation-curable coatings. These coatings are usually applied on the optical fiber in liquid form, and then exposed to radiation to effect the curing. The type of radiation that can be used for curing coatings, must be such as to be able to initiate the polymerization of one or more radiation-curable components such coatings. Radiation suitable for curing such coatings, it is well known and includes ultraviolet radiation (hereinafter UV)and electron beam (E). The preferred type of radiation for curing coatings used for obtaining an optical fiber with a coating that is UV.

[0004] Coating, which is in direct contact with the optical fiber, called primary coating, and the coating that covers the primary coating, referred to as the secondary coating. In the field of radiation curable coatings for optical fibers is known that the primary coatings are softer than the secondary coating. One advantage of this layout is the increased resistance is Troshina.

[0005] Microengine are sharp, but microscopic curvature of the optical fiber involving local axial displacement on a few micrometers and spatial wavelengths of a few millimeters. Microengine can be caused by thermal stress and/or mechanical shearing forces. In case of their presence microengine weaken the ability of the signal transmission optical fiber coating. Weakening is an undesirable decrease of the signal transmitted by the optical fiber. Relatively soft primary coating provides resistance optical fiber to microshell, thereby minimizing signal attenuation. Relatively more rigid secondary coating provides resistance manipulative efforts, such as efforts that occur when laying fiber coated in tape and/or the laying of cable.

In the article "UV-CURABLE POLYURETHANE-ACRYLIC COMPOSITION as a SOLID OUTER LAYERS two-layer PROTECTIVE COATINGS FOR OPTICAL FIBERS" ("UV-CURED POLYURETHANE-ACRYLIC COMPOSITIONS AS HARD EXTERNAL LAYERS OF TWO-LAYER PROTECTIVE COATINGS FOR OPTICAL FIBRES") authors W.Podkoscielny and .Tarasiuk, Polim. Tworz. Wielk, edition 41, Numbers 7/8, str-55, 1996, NDN-131-0123-9398-2 described an optimization study of the synthesis of UV-curable urethane-acrylic oligomers and their use as solid protective cover that protects the events for optical fibers. For the synthesis used made in Poland oligotherapy, diethylene glycol, colorvision (Izocyn T-80) and isophorondiisocyanate in addition to hydroxyethyl - and hydroxypropylmethacrylate. Active diluents (butyl acrylate, 2-ethyl hexyl acrylate and 1,4-batangyagit or mixtures thereof) and 2,2-dimethoxy-2-phenylacetophenone as photoinitiator was added to the urethane-acrylic oligomer, which had a polymerization-active double bond. The composition was irradiated with UV light in an oxygen-free atmosphere. I recorded the IR spectra of these compositions was determined by some physical, chemical and mechanical properties before and after curing (density, molecular weight, viscosity as a function of temperature, the refractive index, the content of the gel, the glass transition temperature, shore hardness, young's modulus, tensile strength, elongation at break, heat resistance and the diffusion coefficient of water vapor).

In the article "properties of UV-CURABLE POLYURETHANE-ACRYLATES" ("PROPERTIES OF ULTRAVIOLET CURABLE POLYURETHANE-ACRYLATES") authors M.Koshiba; K.K.S.Hwang; S.K.Foley; D.J.Yarusso and S.L.Cooper; published in J. Mat. Sci., 17, No. 5, may 1982, str-58; NDN-131-0063-1179-2 described the investigation of the dependence between the chemical structure and physical properties of UV-hardened polyurethane-acrylate-based isophorondiisocyanate and towardis the cyanate (TDI). These two systems were obtained with different molecular weight of the soft segment and the content of the crosslinking agent. The results of dynamic mechanical tests showed that it was possible to get one - or two-phase materials, depending on the molecular weight of the soft segment. As more recent Tcpolyol shifted to lower temperatures. Increase using either N-vinylpyrrolidone (NVP), or polietilenglikolsuktsinata (PEGDA) was caused by the increase of young's modulus and tensile strength. Cross stitching NVP increased the fracture toughness of two-phase materials and moved the high temperature peak of the Tcto higher temperatures, and PEGDA were not given these effects. Tensile properties of the two described systems were generally similar.

Usually in the production of radiation curable coatings for use on optical fiber in order to obtain urethane oligomers using isocyanates. In many references, including U.S. patent No. 7135229 "radiation-CURABLE COATING COMPOSITION" ("RADIATION-CURABLE COATING COMPOSITION"), issued on November 14, 2006, assigned to the patentee DSM IP Assets B.V., column 7, lines 10-32 provided the following information as a guide for specialists in the synthesis of the urethane oligomer: "the Polyisocyanates suitable for use in preparation of the of omposite of the present invention, can be aliphatic, cycloaliphatic or aromatic and include diisocyanates, such as 2,4-colorvision, 2,6-colorvision, 1,3-xylylenediisocyanate, 1,4-xylylenediisocyanate, 1,5-naphthalenedisulfonate, m-delete the entry, the n-delete the entry, 3,3'-dimethyl-4,4'-diphenylmethanediisocyanate, 4,4'-diphenylmethanediisocyanate, 3,3'-dimethylphenylsilane, 4,4'-biphenylenediisocyanate, 1,6-hexadienal, isophorondiisocyanate, Methylenebis(4-cyclohexyl)isocyanate, 2,2,4-trimethylhexamethylenediamine, bis(2-isocyanate-ethyl)fumarate, 6-isopropyl-1,3-phenyldiazonium, 4-diphenylmethanediisocyanate, liaindizecign, hydrogenated diphenylmethanediisocyanate, hydrogenated xylylenediisocyanate, tetramethylethylenediamine and 2,5(or 6)-bis(isocyanatomethyl)-bicyclo[2.2.1]heptane. Among these particularly preferred diisocyanates are 2,4-colorvision, isophorondiisocyanate, xylylenediisocyanate and Methylenebis(4-cyclohexylidene). These diisocyanate compounds are used either individually or in combination of two or more".

[0006] Microengine are sharp, but microscopic curvature of the optical fiber involving local axial displacement on a few micrometers and spatial wavelengths of a few millimeters. Microengine can be caused by thermal strain is mi and/or mechanical shearing forces. In the presence of microengine weaken the ability of the signal transmission optical fiber coating. Weakening is an undesirable decrease of the signal transmitted by the optical fiber.

[0007] a Relatively soft primary coating provides resistance optical fiber formation microthiol, which leads to reduction in the ability to the signal transmission optical fiber with the coating and is therefore undesirable. Microengine are sharp, but microscopic curvature of the optical fiber involving local axial displacement on a few micrometers and spatial wavelengths of a few millimeters. Microengine can be caused by thermal stress and/or mechanical shearing forces. Coatings can provide protection from shear forces, protecting the optical fiber from the formation of microthiol, however, with decreasing diameter of the coating is reduced provide a degree of protection. The relationship between coverage and protection from the transverse stress, which leads to the formation of microthiol, is discussed, for example, in the work D.Gloge "Sheath of the optical fiber and its effect on the straightness of the fibers and transmission losses" ("Optical-fiber packaging and its influence on fiber straightness and loss", Bell System Technical Journal, volume 54, 2, 245 (1975); W.B.Gardner, "Losses micro is shibah in optical fibers" ("Microbending Loss in Optical Fibers"), Bell System Technical Journal, volume 54, Number 2, str (1975); .Yabuta, "Structural analysis of the optical fibers with a protective shell under lateral pressure" ("Structural Analysis of Jacketed Optical Fibers Under Lateral Pressure"), J.Lightwave Tech., including LT-1, Number 4, str (1983); L.L.Blyler, "Polymer coatings for optical fibers" ("Polymer Coatings for Optical Fibers"), Chemtech, str.682 (1987); J.Baldauf, "Dependence of mechanical characteristics of single-mode optical fibers with a double coating and losses microshear" ("Relationship of Mechanical Characteristics of Dual Coated Single Mode Optical Fibers and Microbending Loss", IEICE Trans. Commun., that I-In, Number 4, 352 (1993); and .Kobayashi, "investigation of the loss of signal when microshear in fibers with thin coatings and fiber tapes" ("Study of Microbending Loss in Thin Coated Fibers and Fiber Ribbons"), IWCS, 386 (1993). More solid outer primary coating, that is, the secondary coating provides resistance to handling stress, such as efforts that arise when laying fiber coated in tape and/or the laying of cable.

[0008] the Composition of the secondary coating of the optical fibers before curing usually contain a mixture ethyleneimine compounds, often consisting of one or more oligomers which are dissolved or dispersed in a liquid Ethylenediamine thinners, and photoinitiators. The composition of the coating is usually applied to the optical fiber in liquid form, and then exposed to actinic is zlecenia for curing.

[0009] In many of these compositions was applied urethane oligomer bearing a reactive end groups and the polymer main chain. In addition, the compositions typically contain reactive diluents, photoinitiators, to make compositions curable by UV radiation, and other suitable additives.

[0010] In the published PCT patent application WO 2005/026228 A1-Curable liquid polymer composition" ("Curable Liquid Resin Composition"), published 24.03.2005 some years, the name of the authors Sugimoto, Kamo, Shigemoto, Komiya and Steeman described and claimed curable liquid polymer composition comprising: (A) a urethane(meth)acrylate having a structure derived from the polyol, and srednecenovogo molecular weight of 800 g/mol or more, but less than 6000 g/mol, and (B) a urethane(meth)acrylate having structure, derived from the polyol, and srednecenovogo molecular weight of 6000 g/mol or more, but less than 20,000 g/mol, and the total amount of the component (a) and component (b) is 20-95 wt.% from the curable liquid polymer composition, and the content of component (C) is 0.1-30 wt.% from the amount of the component (a) and component (B). Superimposed on each of the primary and secondary coatings described in this document do not meet the requirements set forth in the formula of the present invention, in particular, in relation to the percentage of reacted acrylic is Noah unsaturation (% RAU) and in-situ modulus primary coating.

[0011] For use as a polymer main chain of the urethane oligomer was offered a lot of material. For example, the urethane oligomers used polyols, such as hydrocarbon polyols, simple polyether polyols polycarbonatediol and complex polyether polyols. Complex polyether polyols are preferred due to their availability on the market, oxidation stability and versatility, allowing you to adapt the characteristics of the coating by modification of the main chain. The use of complex polyether polyols of the polymer main chain in urethaneacrylate the oligomer described, for example, in U.S. patents 5146531, 6023547, 6584263, 6707977, 6775451 and 6862392, as well as in the European patent 539030 A.

[0012] the Problems of cost, use and processing of precursors of urethanes led to the use of basurmanova oligomers in the coating compositions. For example, basurmanova complex preferability oligomers used in the radiation curable compositions of coatings for optical fibres. In the Japan patent 57-092552 (Nitto Electric) described the coating of optical glass fiber comprising polyester di(meth)acrylate, where koinopolitia main chain has an average molecular weight of 300 or more. In the application for patent in Germany 04126860 A1 (Bayer) described a matrix material for tremolo is evident tape consisting of lozhnopolaugitionah oligomer, 2-(N-butyl-carbamyl)acrylate as a reactive diluent and 2-hydroxy-2-methyl-1-phenyl-propane-1-it as photoinitiator. In the patent application of Japan 10-243227 (publication No. 2000-072821) described liquid curable polymer composition comprising lozhnopolojitelny oligomer, which consists of polyetherdiol bearing as the active end groups of two decollate or anhydride and ending with hydroxyethylacrylate. In U.S. patent 6714712 B2 describes radiation-curable coating composition comprising lozhnopolojitelny and/or Alcide-(meth)acrylate oligomer containing the corresponding polyacidic the remainder or its anhydride, optional reactionnary diluent and optionally photoinitiator. In addition, the article Mark D.Soucek and Aaron H.Johnson "New intramolecular effect observed for polyesters: Anomeric effect" ("New Intramolecular Effect Observed for Polyesters: An Anomeric Effect"), JCT Research, volume 1, Number 2, str (April 2004)described the use of hexahydrophthalic acid hydrolytic stability.

Superimposed on each of the primary and secondary coatings described in this document do not satisfy the physical requirements set forth in the formula of the present invention.

[0014] EP-A-1408017 describes radiation-curable composition containing a radiation-curable oligomers, but not specifically discloses the primary coating.

[0015] WO-A-98/50317 contains consolidated tape, which contains many coated optical glass fibers with colored or colored outer primary coating (also known as the secondary coating) on at least one of the coated optical glass fibers and a matrix material that binds this set covered optical fibers with each other. This document does not specifically disclose the primary coverage.

[0016] US-A-2003/0100627 discloses coated optical fiber containing a fiber coated with a combination of inner primary coating (also known as a primary coating and the outer primary coating (also known as secondary coverage). The combination of inner and outer primary coatings described in this document does not meet the physical requirements set forth in the formula of the present invention.

Superimposed on the other of the primary and secondary coatings, described in this document do not satisfy the physical requirements set forth in the formula of the present invention, in particular, in relation to the percentage reacted acrylate unsaturation (% RAU) primary coverage.

Superpatriot

[0064] After the primary coating and secondary coating synthesized, are applied on the optical fiber. Average experts in the art are aware of how to manufacture the optical fiber. The coating on the optical fiber typically occurs in the same place where the manufactured optical fiber itself.

[0065] in the Beginning put the primary floor, and when using the "wet on dry" the next stage is that the radiation source impinges on the primary floor, causing the cured primary coating. When using the "wet on wet" the next stage consists of applying a secondary coating.

[0066] In any case, after the primary coating is applied over the primary coating is applied to the secondary floor, exposed radiation and utverjdayut secondary coating.

[0067] the Radiation used for curing coatings, is any radiation capable of initiating the polymerization reaction. Radiation, under Odysee for curing coatings as is known, includes ultraviolet (UV) and electron beam (E) radiation. The preferred type of radiation for curing the primary and secondary coatings according to the invention used in an optical fiber is UV radiation. This combination of the primary coating and the secondary coating is referred to as superpatriot.

[0068] Superpatriot can be successfully applied to the optical fiber at a linear speed between 750 m/min and 2100 m/min

[0069] After the secondary coating overiden not necessarily put a layer of "paint", and then covered and coated optical fiber is placed next to the other covered and coated optical fibers in a combined tape and use a radiation-curable matrix coating for holding the optical fibers in the desired position in the team the tape.

[0070] Preferably, superpatriot includes a primary coating selected from the group consisting of a primary coating of CR, the primary coating P, primary cover, SA and BJ primary coating and secondary coating selected from the secondary cover D and the secondary coating R, as defined here.

[0071] the Combination of superority with the physical properties of both primary and secondary coating on the optical fiber or wire used in the simulator extraction columns, socl is optimal.

[0072] Examples of the simulator exhaust columns

[0073] In the early years of the development of coatings of optical fibers all newly developed primary and secondary coatings were first tested on the hardened properties of their films, and then sent for evaluation at the columns of pulling the fiber. All of the coatings that were required to pull, as it was found, at most 30% of them have experienced the extraction column due to the high cost and difficulties in scheduling. The time from the moment when the surface was first drawn up, until the moment when it is applied to fiberglass, was usually about 6 months, which has slowed down the development cycle of the product.

[0074] In the technology of radiation hardened coatings for optical fibers is known that, when either the primary coating, a secondary coating applied to the glass, its properties often differ from the properties of flat film of the same of the cured coating. I believe that this is due to the fact that the coating on the fiber and flat film coatings have differences in sample size, geometry, intensity of UV radiation, the total dose received UV radiation, speed of processing, the temperature of the substrate, the curing temperature and possibly inert conditions in a nitrogen atmosphere.

[0075] In order to provide more robust development of the coating and the treatment period introduction we developed the equipment, which would support curing, similar to the conditions existing in the manufacturing of fiber. This type of alternative equipment for applying and curing should be easy to use, have low operating costs and to give reproducible technological parameters. The name of this equipment - simulator extraction columns", hereinafter abbreviated as denoted by the "CPI". Simulators exhaust columns developed on request of the consumer and create on the basis of a detailed study of the structural elements of the real pillars of glass fiber drawing. All measurements (position lamps, the distance between the rungs of the coating, the gaps between the steps of coating and UV lamps etc. are copied from the columns of glass fiber drawing. This allows you to simulate the process conditions used in the industrial production of glass.

[0076] One of the known CPI has five lamps Fusion F600: two for the top step of coating and three on the bottom. The second lamp at each stage can be rotated at different angles between 15-135°, providing a more detailed study of the curing profile.

[0077] the "Core"used in the known CPI, is a conductor (wire) stainless steel diameter 130,0±1,0 μm. To assess the available applicators for pulling the fiber of different designs from different vendors. This configuration provides a coating on the optical fiber under conditions similar to those which actually exist in the industry.

[0078] the exhaust Simulator columns have been used to deepen the analysis of radiation-curable coatings for optical fiber. Method of measuring in-situ modulus of the primary coating, which can be used to determine the strength of the coating, the degree of curing and performance of fiber in different environments was presented in 2003 ...Steerhan, J J.M.Slot, H.G.. van Melick, A.A.F. v.d. Ven, NSA and R.Johnson in Materials 52nd International Symposium cable-wire products (the Proceedings of the 52nd IWCS), str (2003). In 2004 Steeman with co-authors reported how the rheological profile of the coatings of the optical fibers at high shear rate can be used to predict the maintainability of the coatings at higher speeds stretching, see ...Steeman, W.Zoetelief, NSA and M.Bulters, Materials 53rd IWCS conference, str (2004). Simulator extraction columns can be used to further study the properties of the primary and secondary coating on the optical fiber.

[0079] test Methods

[0080] the test Method for percent reacted acrylate unsaturation in the primary coating, shortly denoted as % RAU.

[0081] the Degree utverzhdeni the inner primary coating on an optical fiber or a metal wire is determined using infrared spectroscopy with Fourier transform (FTIR) with a diamond fittings the ATR. The parameters of the device FTIR include: 100 jointly imposed scans, resolution 4 cm-1detector DTGS, spectral range 4000-650 cm-1and approximately 25%reduction in the default rate mirrors to improve the ratio of signal to noise ratio. Requires two spectra: one for the uncured liquid coating, which corresponds to the coating on the fiber or wire, and one for the inner primary coating on the fiber or wire. In the Central area of 2.54-cm (1-inch) square piece of Mylar film thickness of 76 microns (3 mil) smear a thin film of contact glue. After contact adhesive becomes sticky, he placed a piece of optical fiber or wire. The sample is placed under an optical microscope with low magnification. The coating on the fiber or wire to cut glass using a sharp scalpel. Then cover the cut longitudinally to the outer side of the fiber or wire to approximately 1 cm, making sure that the cut is clean and that the external coating is not bent on the primary floor. Then cover the spread on contact adhesive so that the primary floor next to the glass or wire disclosed in the form of a flat film. Fiberglass or wire break in that place, where disclosed primary coverage.

[0082] Range of liquid covered what I get after completely coating the diamond surface coating. The liquid must be from the same batch, which is used for coating the fiber or wire, but the minimum requirement is that it must be of the same composition. The final format of the spectrum must be on the uptake. Open primary coating on the Mylar film was placed in the center of the diamond, with the axis of the fiber or wire parallel to the direction of the infrared beam. To the reverse side of the specimen shall be applied the pressure to ensure good contact with the crystal. The spectrum should not contain any absorption bands from the contact adhesive. If the peaks of contact adhesive may be necessary to prepare a fresh sample. It is important to remove the range directly after sample preparation, and not to prepare some other samples and to remove spectra after all samples will be prepared. The final format of the spectrum must be on the uptake.

[0083] for the liquid, and to the cured coating measure the peak area as the peak of the double bond of the acrylate at 810 cm-1and control the peak in the field of 750-780 cm-1. The peak area determined using the method baseline, where baseline is Vybrat tangent to the minima of the absorption on both sides of the peak. Then determined the area under the peak and above the base line. The limits of integration for MS the who and the cured samples are not identical, but like that, especially for the control of the peak.

[0084] the Ratio of the peak area of the acrylate to the square of the control peak detect and liquid, and for the cured samples. The degree of cure, expressed as a percentage reacted acrylate unsaturation (% RAU), is calculated by the following equation:

,

where RLrepresents the ratio of the area of the liquid sample, a RF- the ratio of the area of the cured primary coating.

[0085] the Method for testing the % RAU secondary coverage: the Degree of curing the outer coating on the optical fiber is determined using FTIR with diamond snap the ATR. The parameters of the device FTIR include: 100 jointly imposed scans, resolution 4 cm-1detector DTGS, spectral range 4000-650 cm-1and approximately 25%reduction in the default rate mirrors to improve the ratio of signal to noise ratio. Requires two spectra: one for the uncured liquid coating, which corresponds to the coating on the fiber, and one for the external coating on the fiber. Range of liquid coatings obtained after complete coverage of the diamond surface coating. The liquid must be from the same batch, which is used for coating on the fiber, but the minimum requirement is that it must Battalova same composition. The final format of the spectrum must be on the uptake.

[0086] the Fiber mounted on diamond pad and applied to the fiber sufficient pressure to obtain a spectrum that is suitable for quantitative analysis. For maximum spectral intensity of the fiber should be placed in the center of the diamond parallel to the direction of the infrared beam. If one fiber is received insufficient intensity, on the diamond, you can put 2-3 fibers are parallel to each other and at the close the distance. The final format of the spectrum must be on the uptake.

[0087] for the liquid, and to the cured coating measure the peak area as the peak of the double bond of the acrylate at 810 cm-1and control the peak in the field of 750-780 cm-1. The peak area determined using the method baseline, where the baseline was chosen tangent to the minima of the absorption on both sides of the peak. Then determine the area under the peak and above the base line. The limits of integration for liquid and cured sample are not identical, but similar, especially for the control of the peak.

[0088] the Ratio of the peak area of the acrylate to the square of the control peak detect and liquid, and for the cured samples. The degree of cure, expressed as a percentage reacted acrylate unsaturation (% RAU), calculated at the following level is the s:

where RLrepresents the ratio of the area of the liquid sample, a RF- the ratio of the area of the cured coating.

[0089] the Method of testing in-situ modulus of the primary coating In-situ modulus of the primary coating on the glass fiber or metal fiber-wire with two coverings (soft primary coating and a solid secondary coverage) measured in this test method. A detailed discussion of this test can be found in Steeman, P.A.M., Slot, J.J.M., Melick, N.G.H. van, Ven, A.A.F, van de, Cao, H. & Johnson, R. (2003), "Mechanical analysis tests in-situ modulus of the primary coating on the optical fibers in the Materials of the 52nd International Symposium cable-wire products (IWCS, Philadelphia, USA, 10-13 November 2003), article 41. For sample preparation, remove a short section (length ~2 mm) of the coating layer using a tool for removing insulation, at a distance of ~2 cm from the end of the fiber. Fiber cut, having the other end exactly on the measured distance of 8 mm from the edge of the removed cover to the end of the fiber. Then part 8-mm coated fiber is inserted into a metal clamping device for samples, as schematically shown in Figure 6 in the paper [1]. Coated fiber pomest in microtrace in the mounting bracket; microtube consisted of two polos indecency recesses; its diameter was selected approximately the same as the outer diameter (~245 µm) standard fiber. Fiber tightly clamp after tightening the screw; clamping force on the surface of the secondary coating was homogeneous and significant deformation in the coating layer does not occur. Then clamping device with the fiber mounted on the device DMA (Dynamic Mechanical Analysis): the analyzer Rheometrics RSA-II). Metal clamping device is clamped by the lower clamp. The upper clamp is tightened, pressing on the upper part of the coated fiber to such an extent that he destroyed the coating layer. Clamping device and the fiber must be strictly vertical. You need to ensure that not sandwiched portion of the fiber had a constant length for each sample, in our tests - 6 mm Offset deformation regulated by setting the axial pretensioning almost zero (-1 g ~ 1 g).

[0090] To measure the shear modulus G of the primary coating selected geometric layout of the two-sided test on the shift. The width of the sample, W, in two-sided test shift introduced is equal to 0.24 mm, which was calculated according to the following equation:

where Rfand Rprepresent the outer radius of the bare fiber and the primary coating, respectively. To calculate use geo is atriu standard fiber, Rf=62.5 μm and Rp=92,5 μm. In geometry, two-sided test shift enter the length of the sample 8 mm (clamped plot) and a thickness of 0.03 mm (the thickness of the primary coating). Testing was performed at room temperature (~23°C). Used the measurement frequency was 1.0 rad/S. the shear Deformation ε set at 0.05. Conduct dynamic time base, having 4 experimental points measured storage modulus shear G. Given G value represents the average value for all experimental points.

[0091] Then, the measured shear modulus G adjusted according to the correction method described in the article [1]. Correction is needed to account for the stretching of the glass pressed and not pressed parts. In the correction procedure, you must enter the modulus of elasticity tensile bare fiber (Ef). For fiberglass Ef=70 GPA. For fiber-wire stainless steel S314 Ef=120 GPA. The adjusted value of G then Ousterhout using the actual values of Rfand Rp. For optical fiber geometry, fiber, including the values of Rfand Rpmeasure using RC Fiber Geometry System. For fiber-wire Rfis 65 μm when using wire stainless steel S314 diameter of 130 μm; Rpmeasured under a microscope. Finally, in-situ module panel the guests E (modulus tensile) for the primary coating on the fiber is calculated according to the formula E=3G. Given the value of E is the average of three test specimens.

[0092] the Method of testing in-situ modulus secondary coating In-situ modulus secondary coating on glass or metal volkmarode with two coverings (soft primary coating and a solid secondary coverage) measured in this test method. For sample preparation, with fiber peeling off layers of coating a length of ~2 cm in the form of a solid tube cover with one end covered with fiber, first immersing the end of the coated fiber with a tool for removing insulation in liquid N2for at least 10 seconds, and then pulling the tube cover fast movement, until the layers of the coating remain hard. Device DMA (Dynamic Mechanical Analysis): the analyzer Rheometrics RSA-II) is used to measure the elastic modulus of the secondary coating. In the case of a fiber with two coating secondary coating has a much higher modulus of elasticity than the primary coating; therefore, the contribution of the primary coating in the results of the dynamic tensile test, made with a pipe coating, can be neglected. For RSA-II, in which the regulation of the distance between the two clamps is limited, the sample tube cover may be shorter than the distance between the two clamps. A simple sample holder, made the first metal plate, curved and contractible in the open end of the screw, is used to firmly hold the sample tube covering the bottom end. Shift the clamping device in the center of the lower clamp and tighten the clamp. With tweezers pipe coating line in vertical position through the top clamp. The upper clamp is closed and tighten. The offset strain to regulate until pretensioning not reached values of ~10,

[0093] the Test was performed at room temperature (~23°C). In the dynamic mode of tensile test DMA the measurement frequency was set equal to 1.0 rad/s; the deformation is 5E-4. Chose a cylindrical geometry. The sample length equal to the length of the tube cover between the top edge of the metal clamping device and the lower clip, in our test-11 mm Diameter (D) was administered equal to 0.16 mm according to the following equation:

where Rsand Rprepresent the outer radius of the secondary and primary coatings, respectively. For calculations using the standard geometry of the fiber, Rs=122,5 μm and Rp=92,5 μm. Conduct dynamic time base and write 5 experimental points of the storage modulus tensile means that the value E represents average value for all the experiments is analnyj points. Then, the measured modulus E is correct, multiplying by a correction factor, which uses the actual geometry of the fiber. The correction factor is as follows:

For fiberglass actual geometry of the fiber, including the values of Rsand Rpmeasure using system RC Fiber Geometry System. For fiber-wire values of Rsand Rpmeasured under a microscope. Given the value E represents the average of three test specimens.

[0094] the Method of testing in-situ measurement of Tcthe primary and secondary coating:

The glass transition temperature (Tc) the primary and secondary coatings on glass or metal fiber-wire with two coatings measured by this method. These glass transition temperature is referred to as "Tctube".

[0095] For sample preparation, with the fiber removed layer covering length ~2 cm in the form of a solid tube cover with one end covered with fiber, first immersing the end of the coated fiber with a tool for removing insulation in liquid N2for at least 10 seconds, and then pulling the tube cover fast movement, until the layers of the coating remain hard.

[0096] the Device DMA (Dynamic Mechanical Analysis): use the analyzer Rheometrics RSA-II). In the case of RSA-II gap between the two sage the AMI RSA-II can be extended up to 1 mm The gap is initially set to the minimum level by adjusting the offset strain. A simple sample holder, made in the form of a metal plate, curved and contractible in the open end of the screw, is used to firmly hold the sample tube covering the bottom end. Shift the clamping device in the center of the lower clamp and tighten the clamp. With tweezers pipe coating line in vertical position through the top clamp. The upper clamp is closed and tighten. Heat chamber is closed and set the temperature in a heating Cabinet at a value greater than Tcfor secondary coverage, or 100°C, liquid nitrogen as a medium for temperature control. When the temperature of the heating Cabinet has reached this temperature, the offset strain to regulate until the pre-tensioning did not reach values from 0 g to 0.3 g

[0097] When conducting dynamic tests DMA at step temperature change of the frequency measurement determine a equal to 1.0 rad/s; the deformation is 5E-3; a step change in temperature is 2°C and the holding time is 10 seconds. Chose a cylindrical geometry. Set geometry parameters were the same as used for testing in-situ modulus of the secondary coating. The sample length equal to the length of the tube coating between faiths is it the end of the metal clamping device and the lower clamp, in our test-11 mm Diameter (D) was administered equal to 0.16 mm according to the following equation:

where Rsand Rprepresent the outer radius of the secondary and primary coatings, respectively. For calculations using the standard geometry of the fiber, Rs=122,5 μm and Rp=92,5 mm.

[0098] the Dynamic test at step temperature change is carried out from the initial temperature (100°C in our test) to a temperature below Tcprimary coverage or -80°C. After completion of the test cycle peaks on the curve of tan δ log Tcprimary coverage (corresponding to a lower temperature) and Tcthe secondary coating (corresponding to a higher temperature). It should be noted that the measured glass transition temperature, especially for the glass transition temperature of the primary coating should be considered as relative values of glass transition temperatures for the layers of the coating on the fiber due to the shift of the tan δ due to the complicated structure of the tube cover.
