Abstract
A buffered optical waveguide fiber suitable for use in forming an optical waveguide cable is described. An optical waveguide fiber is first coated with a glass protective coating applied to the exterior longitudinal surface of the fiber with a release agent coating applied over the glass protective coating. Thereafter, a protective layer of a thermoplastic synthetic resinous material surrounding the fiber is disposed over the coating of release agent.
