摘要： An optical fiber package (52) includes a length of optical fiber (22) wound in a plurality of convolutions on a bobbin (50). In order to maintain the convolutions in a precision wound package and to prevent snags during payout, it is necessary that each convolution of optical fiber be adhered to at least a portion of an adjacent convolution. This is accomplished by providing the length of optical fiber with an adhesive material (32) which is not tacky at room temperature but which becomes tacky at a predetermined temperature. After the convolutions have been wound on the bobbin, the bobbin is treated to cause the adhesive material to become tacky and cause each convolution to adhere to at least a portion of adjacent convolutions. Suitable adhesion is caused to occur with any adhesive material for which molecular bonding can occur across the interface between contiguous portions of adjacent convolutions as a result of suitable treatment. The adhesion between convolutions is sufficient to cause a precision wound package to be maintained, but is such as to allow separation of each convolution from an adjacent convolution during payout without the occurrence of breaks.

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： A hermetically sealed optical fiber cable (20) includes a core (21) comprising a plurality of optical fiber ribbons (22,22) disposed within a core tube (30) comprised of a high temperature resistant polymeric material. The core tube is disposed within a hermetic sealing member (40) which comprises a metal of low electrochemical activity having a sealed seam. An outer jacket (50) is disposed about the hermetic sealing member. The core may be filled with a waterblocking filling material (35). The material of the core tube undergoes only limited degradation because of the limited amount of oxygen and/or moisture trapped in the hermetically sealed cable. The filling material and/or other materials of the cable scavenge moisture and oxygen which travel longitudinally of the cable and reach portions of the cable subjected to a high temperature because of a leak in an adjacent steam line. The filling material and/or other materials are such that they cooperate with polymeric materials of the cable to prevent oxygen and humidity from degrading coating material of the optical fiber. Further, the filling material and the core tube are such that degradation of the core tube in the hermetically sealed cable is avoided.

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.
