摘要： An optical fiber (21) which has been drawn from a preform (22) is moved into and through a chamber (38) of a housing. A source of vacuum is connected to the chamber to prevent the attachment of air pockets to the optical fiber as it is being moved through the chamber and through an opening of a die. The die includes a flow path (55) which is substantially normal to the path of travel of the optical fiber and the die opening is substantially larger than the diameter of the optical fiber. The thickness of the flow path in a direction along the path of travel is sufficiently small so as to prevent the recirculation of the coating material in the vicinity of the point of application to the optical fiber. Also, the fiber draw rate, the pressure of the coating material the direction of the flow path relative to the longitudinal axis of the optical fiber and the diameter of the die opening are such that a gap forms between the coating material and the die. That gap is allowed to be maintained because of the pressure differential between ambient atmosphere an the chamber. As a result, the coating material as it leaves the disc-like flow path and is directed toward the optical fiber is bounded by free surfaces instead of by solid surfaces in the immediate vicinity of where it is applied to the optical fiber. This prevents the development of shear fields and allows the diameter of the coated optical fiber to be varied.

摘要： Fibers are coated with two (or more) layers. A first coating liquid is applied by an applicator having a die that provides for the formation of a gap between the die and the first coated layer. A second die is located at the exit of the first die, with the second coating liquid flowing onto the fiber through a relatively narrow clearance between the first and second dies. The clearance is formed by die surfaces perpendicular to the fiber axis. This second die also provides for a gap, so that the second layer is applied at a "free surface" at the point of contact with the first coated layer. This approach eliminates turbulence and coating nonuniformities associated with prior art multiple coating techniques.

摘要： In order to recoat bared end portions (32--32) of optical fibers (34--34) which have been spliced together, the spliced portions of the fibers and portions adjacent thereto are positioned in a groove (51) of a base plate (43) of a mold and enclosed with a cover (60). The cover is slidably moveable relative to the groove to allow an injection nozzle (81) which extends through the cover to become aligned with the fiber. Coating material (92) is introduced through the nozzle into engagement with the spliced end portions after which the cover is moved relative to the base plate to shear across the coating material along the interface between the cover and the base plate. Movement is discontinued when a channel (86) in the cover becomes aligned with the recoated splice. This allows the coating material to be solidified in the presence of a free surface (90) which avoids the formation of bubbles in the coating material and causes the recoated portion to remain in engagement with the original coated portions adjacent to the spliced end portions.

摘要： The present invention continuously monitors the amount of curing radiation available for curing coating material on a moving optical fiber and includes a curing system having a radiation source capable of providing radiation energy for curing coating material on an optical fiber and a reflector system which redirects non-direct radiation back toward the article. An optical fiber which has been provided with a curable coating material is moved along a path of travel through a curing area. The coating material is cured by causing the radiation source to emit energy suitable for curing the curable coating material. The predictable average amount of light energy properly redirected by the reflector system toward the curable article is sensed as the curable coating material is being cured to obtain continuous in-process reading. The average radiation value is obtained by positioning three longitudinally aligned holes adjacent the fiber path and between the fiber and a radiation sensing device. Furthermore, the amount of the light energy available from the reflector system may be sensed at a location which is outside the reflector system to obtain a reference reading. The in-process readings may then be compared with the reference reading to determine the portion of the radiation available from the radiation source which is actually available for curing the curable coating material.

摘要： Optical fiber and cable performance are assured by a category of UV-cured polyurethane acrylates. Low cost is the consequence of use of the polycarbonate oligomer. Good performance and long life are ascribed to other ingredients of the coatings. Dependence on the hindered phenols for antioxidant protection assures sufficient protection for these inherently stable materials without incurring fiber damage found to result from use of hindered amine antioxidants.

摘要： A sheathed optical fiber (15) which may be used in a package (20) in guidance systems for tethered vehicles includes a carrier (21) on which are wrapped a plurality of convolutions of the sheathed optical fiber. The sheathed optical fiber in a preferred embodiment includes a metallic tubular member (40) with optical fiber (30) being disposed in a longitudinally extending passageway (42) of the tubular member and secured therein against unintended lateral disassociation with the tubular member in a manner which minimize microbending losses. The reinforced optical fiber has mechanical ruggedness and tensile load capability which render it ideal for use in tethered vehicles.

摘要： An optical fiber transmission medium (30) ) includes optical fiber (21) provided with a coating system (31) typically including two layers each of a different coating material. An inner layer (32) of a first coating material is called the primary coating and an outer layer is termed the secondary. In order to achieve desired performance characteristics, performance is related to properties of a coating system. The coating materials have well defined moduli and the second coating material has an elongation which is substantially less than in prior secondary coating materials. Adhesion levels which are optimized rather than maximized are substantially stable with respect to time. Curing of the coating materials may be accomplished simultaneously or in tandem with the application separately of the coating materials.

摘要： Drawn optical fiber is provided with at least one layer of a coating material. The coating material typically is a UV curable material and provides the optical fiber with mechanical and environmental protection. It has been found that the temperature at which the optical fiber is cured has a pronounced effect on the modulus of the cured coating material. In order to provide a coated optical fiber of which the coating material has a desired modulus, the temperature of the coating material during cure is controlled by controlling the amount of energy of infrared wavelength which impinges on the coating material.

摘要： A coated fiber strand including at least one heterogeneous region present in one or more coating layers. The heterogeneous region(s) preferably comprises a material useful for coding of the fiber. The optical fiber can include a primary coating layer and a secondary coating layer where the heterogeneous region(s) defines one or more colored stripes in or on the secondary coating layer. A method for forming a coated fiber, such as an optical fiber, includes introducing at least one coating layer onto a fiber strand such that one or more coating layers cover a portion of the surface of the strand. At least one heterogeneous region is introduced into or onto one or more coating layers, and the strand is cured to provide a desired product. A desired functionality, e.g., coding, can thus be introduced onto a fiber without adversely effecting subsequent processing steps, e.g., curing of the coating layer(s).

摘要： The outside coating of dual coated optical fibers is improved by the addition of a filler to increase the microbending resistance of the optical fiber. The coating is improved by the addition of very small clay platelets, with the platelets aligned along the fiber axis. It is found that standard polymer coatings can be loaded with enough filler to enhance the mechanical properties, while the particulates are small enough to be essentially transparent to the UV curing radiation.
