Description

The system and method for coating on curing optical fiber

Technical field

The system and method that the coating on curing optical fiber is related generally in terms of present disclosure.Specifically, present disclosure Different aspect be related to coming using light emitting diode (LED) device of the radiation-curable coating on curing optical fiber, system and Method.

Background

Optical fiber uses and has the advantages that some for being better than other media in various applications.For example, data can be with It is transmitted by optical fiber with data rate more higher than process electric wire.Optical fiber is lighter than electric wire and more flexible, therefore optical fiber is frequent Data transmission is used in telecommunications industry.However, if be not protected, because transmitting the thin glass of optical signalling across it The fragility of precursor, optical fiber are not suitable for onsite application.In addition to its sensibility to physical damage, uncoated optical fiber will also be by To the negative effect of contact with moisture.As a result, typically surface coating is administered on optical fiber for protecting and ensuring height Horizontal performance.

Optical fiber is produced by traction often to be coated with the radiation-curable coating of two or more superpositions immediately.Directly The coating of contact optical fiber is known as " coating of internal layer " and covers coating referred to as " outer layer secondary coating ".In some bibliography In, coating of internal layer is simply referred as " coating " again and outer layer secondary coating is known as " secondary coating ".Typically will Coating of internal layer is at lower modulus more notable than secondary coating.

Coating of internal layer of flexible relative provides the resistance for microbend, which leads to the letter of the optical fiber of coating Number transmission attenuation increases, therefore is undesirable.Microbend be related to several microns local axial displacement and several millimeters Microcosmic curvature in the optical fiber of space wavelength.Microbend can be induced by thermal stress and/or mechanical lateral force.Coating can provide Protect optical fiber from the protection of the lateral forces of microbend, but as paint thickness reduces, the amount of the protection provided drops It is low.Such as in D.Gloge, " optical fiber cladding and its influence (Optical-fiber for optical fiber straightness and loss Packaging and its influence on fiber straightness and loss) " Bell System Technical Journal (BellSystem Technical Journal), volume 54,2,245 (1975);The W.B.Gardner, " microbend in optical fiber It is lost (Microbending Loss in Optical Fibers) ", Bell System Technical Journal, volume 54, the 2nd phase, the Page 457 (1975);J.Baldauf, " mechanical property of the single mode optical fiber of double coatings and the relationship of microbend loss (Relationship of Mechanical Characteristics of Dual Coated Single Mode Optical Fibers and Microbending Loss) ", IEICE communicates journal (IEICE Trans.Commun.), the E76-B volumes, the 4th phase, 352 (1993);And K.Kobayashi, " the microbend loss research in optical fiber and fibre ribbon that scumbling is covered (Study of Microbending Loss in Thin Coated Fibers and Fiber Ribbons) ", IWCS, Discussed in 386 (1993) coating and from cause microbend lateral stress protection between relationship.Harder outer layer Secondary coating (that is, secondary coating) is provided for processing power (as when being formed band-like by the optical fiber of coating and/or met when twisting into cable To those of) resistance.

Before curing, optical fiber secondary coating composition generally includes the mixture of following item:Often by dissolving or dividing The ethylenically unsaturated compounds and light for the one or more oligomer composition being dispersed in liquid ethylenic bond unsaturation diluent draw Send out agent.Typically the coating composition is administered on optical fiber in liquid form, and is then exposed under light radiation to carry out Solidification.

Coating preferably has refractive index more higher than the covering of associated optical fiber, to allow it by the light of mistake Signal is learned to remove from the core of the optical fiber.Coating should maintain during heat and hydrolysising aging and the enough of glass optical fiber glues Attached, also (change if necessary) can be strippable by its for engagement purpose.The typical thickness of coating is in 20-50 In μ m (for example, about 25 or 32.5 μm), thinner thickness (optical fiber for 200 μm) in 15-25 μ ms.

Coating preferred thickness is less than about 40 μm.Typically by a coating be administered on glass optical fiber and with After cure.There may also be the various additives for the one or more characteristics for enhancing a coating, including antioxidant, adherency Accelerating agent, PAG compounds, photosensitizer, vehicle surfactant, tackifier, catalyst, stabilizer, surface agent and optical brightening Agent.

Secondary coating is external coating.Secondary coating is that for example its molecular change obtains highly cross-linked Coating material composition upon polymerization The polymerizate of object.In embodiment described here, which has high in situ modulus (for example, being more than at 25 DEG C About 800Mpa, more preferably from about 1Gpa between about 3GPa) and high T_g(for example, greater than about 50 DEG C).The in-site secondary mould Amount is preferably greater than about 1000MPa.Secondary coating applied thickness is generally less than about 40 μm.

Use the optical fiber coating of one of following two methods application internal layer and outer layer coating:Wet pressing is wet (wet-on-wet) (WOW) and (wet-on-dry) (WOD) is done in wet pressing.In WOD methods, optical fiber undergoes a coating application first, and (it is via sudden and violent It is exposed to ultraviolet (UV) radiation curing), it then undergoes secondary coating and applies (it is then cured by similar means).In the side WOW In method, optical fiber undergoes a coating and secondary coating coating, is then carried out at the same time UV or UV-LED solidifications.In the wet method of wet pressing In, the cure lamp between a coating and secondary coating application is omitted.

Optical radiation energy is most important for using the production of the optical fiber of radiation-curable coating.Specifically, solidification process Carry out curing optical fiber coating using the radiation energy from UV lamp.In decades, the UV mercury lamps with broadband spectral are in the industry Preferably, since its high intensity and wide emission spectrum can ensure that the solidification of such radiation-curable coating quickly and completely. However, " electrodeless " microwave lamp feature of such transmitting ultraviolet light is bulky, strong noise, and the opto-electronic conversion of ultraviolet radioactive It is less efficient.

However, recently, increased popularity is had begun using the curing system of UV-LED (light emitting diode) lamp.Based on LED Curing system a large amount of benefits better than conventional mercury lamp are provided.Advantage includes reduced power consumption, greater compactness of design, immediately The ability of switch, longer lamp service life, the heating of less base material, seldom maintenance and better Environmental Sustainability.

However, several disadvantages have limited LED based curing system for the cured adaptability of optical fiber coating and competing Striving property.First, LED light typically generates radiant energy density more smaller than conventional mercury lamp.More LED light may be needed to carry For usual one or two conventional lamp with regard to enough required radiation energies.Secondly, it is normal that LED based lamp source is intended to transmitting ratio Advise the wavelength of the shorter range of lamp.The wavelength of wider range allows radiation energy to penetrate coating with different depth and thus generate more It is uniform bulk cured.Wave-length coverage is limited to be compensated by increasing the radiation energy being administered on coating, but this Sample, which increases power input, to be caused to increase energy consumption cost.

The surface of radiation-curable coating or main body owe solidification, it is possible to create a variety of undesirable results.For example, owing solidification A coating may be deteriorated in the adhesiveness on optical fiber, this leads to and (names just a few) lower optical fiber ablation power (SF), weak Mechanical property (such as weak tensile strength and cavitation intensity) and unstable microbend Reduction Level.

Similarly, owing cured secondary coating also leads to a variety of undesirable results.For example, optical fiber may be caused by owing solidification On protective layer lower modulus, therefore cause difference mechanical protection.Owing cured secondary coating may be due to chemistry or water Code insurance shield reduces, and optical fiber is easy to deteriorate under ambient storage conditions.

When the surface cure percentage of secondary coating is difference, especially when surface cure degree is even below about 90% When, generate the coating surface of viscosity or high frictional force.This can cause optical fiber wind and process lead to the problem of, and may at The interim optical fiber rupture of cable production process.

It has slightly been alleviated with the technological improvement on formulation for coating material in procedure for producing recently and has cured scheme phase using full LED The historic disadvantage of pass.Although however, having these high performance natures, there is no completely by these advanced features for UV LED light It is embodied on Photocurable composition.

With increased optical fiber demand and market competition, modern fiber manufacturing is required to be applicable in higher hauling speed The coating of (up to 2500m/min or higher).Under all other identical conditions, as so-called " hauling speed " continues Increase, the proportional quick reduction of energy of radiation-curable coating is awarded in the unit interval.

When optical fiber is drawn through cure lamp with quick rate, radiation-curable coating needs to receive enough Radiation energy.During production, the curing rate of optical fiber depends on that enough radiation energies can be administered to radiation-curable Coating on cure lamp.However, the radiation energy output for increasing LED based cure lamp may result in some problems, it is all Such as increase energy consumption and more heats, the electric energy and service life that reduce the lamp can be caused.Accordingly, there exist for being used for Use the demand of the improved devices, systems, and methods of LED based curing system curing optical fiber.
