摘要： An optical fiber coated with a single ultraviolet cured resin wherein the attenuation losses are less than 0.5 decibels/kilometer. The resin has a tensile modulus of about 7,800 psi. This cable is particularly useful in loosely wrapped cable structures such as open channel or loose tube cables.

摘要： In the manufacture of optical fibers, at least a portion of a preform of optical glass is heated into a molten state and drawn to create an optical fiber of the desired diameter. To cool the fiber during the drawing process and prior to coating thereof, the invention contemplates providing a cooling device with a laminar flow of inert gas therein to surround and cool the fiber.
