    摘要: A method for manufacturing a coated optical fiber including the step of determining a desired temperature operating range of a coated optical fiber having at least one critical limit. The intercoating delamination stresses at the critical limit of said temperature range are determined. A zero-stress temperature region using the critical limit and the delamination stresses is then selected. An optical fiber is provided and the optical fiber is coated with a first polymer coating. The first polymer coating is exposed to a source of actinic radiation, wherein the source of actinic radiation generates heat. A second polymer coating including a photopolymerizable composition is applied to the optical fiber directly on the first polymer coating. The second polymer coating is cured, where at the time the second polymer coating is cured the first polymer coating is at the zero-stress temperature region.

    摘要: A filament coating apparatus comprising a frame including a first filament holding fixture and a second holding fixture for releasably securing a filament adjacent to an extrusion coating fixture also attached to said frame. The extrusion coating fixture comprises a guide rod, a carriage movably mounted on the guide rod, and a coating head including an opening for directing a curable coating composition to a filament positioned in a channel formed in the coating head. A radiation source is aligned to the coating head for radiation curing of the curable coating composition applied to the filament. Both the coating head and the radiation source are joined to the carriage to move relative to a portion of a filament during application of curable coating composition to its surface.

    摘要: A coated optical fiber adjusted to operate at a predetermined temperature range. The coated fiber includes an optical fiber, a first polymer coating generally concentrically surrounding the optical fiber and a second polymer coating generally concentrically surrounding the first polymer coating, wherein the first polymer coating includes substantially no coefficient of thermal expansion stresses when the optical fiber is placed at a lower end of the temperature range.
