Embodiment Construction

[0023] The coating machine assembly will now be described in detail with reference to the accompanying drawings. While the coater assembly is described with reference to the figures, it is not intended to be limited to the embodiments disclosed herein. On the contrary, it is intended to cover all alterations, modifications and equivalents, which may be included within the spirit and scope of the recoater assembly as defined by the appended claims.

[0024] Referring now to FIG. 1, a system 10 is shown for drawing a cylindrical preform 13 to an optical fiber 11 and subsequently using a preferred embodiment of a multi-position coater assembly 100 according to the present invention. Optical fiber 11 is coated. Typically, the manufacture of optical fiber 11 begins by drawing a glass preform 13, which is maintained in an electric furnace 12 at a temperature of 2000°C or higher. Various gauges 16, such as clad diameter and fiber extensometers, provide feedback to furnace temperatu...

Abstract

An apparatus for applying a primary coating and a secondary coating to an optical fiber is disclosed. The apparatus includes at least one pressurized source of primary coating, a first primary reservoir for applying a first layer of the primary coating to the optical fiber, a first primary die including a first primary land configured to size the first layer of the primary coating, a second primary reservoir for applying a second layer of the primary coating to the optical fiber, a second primary die including a second primary land, a pressurized source of the secondary coating, a secondary reservoir for applying a layer of the secondary coating to the optical fiber, and a secondary die including a secondary land configured to size the layer of the secondary coating.

Description

technical field [0001] The present invention relates generally to coating optical fibers, and more particularly, the present invention relates to an apparatus for applying multiple coatings to an optical fiber. Background technique [0002] The production of optical fibers generally involves drawing an optical fiber, often composed of silica glass, and subsequently applying a protective coating material to the fiber. The primary coating material typically contains a softer polymeric material which protects the fibers from displacement and losses associated therewith. Also, the primary coating helps to absorb forces applied to the coated fibers and prevent them from being transmitted to the fiber core. Typically, a second coat material comprising a higher modulus polymeric material is applied over the primary coat. The second layer maintains the high strength and abrasion resistance of the coated optical fiber. Each fiber after coating must therefore be able to withstand, ...
