Abstract

A double-coated optical fiber and method includes providing a core that serves as a light transmission medium. A cladding surrounds the core and has a smaller reflective index than the core. A primary coating layer is formed of a UV-cured polymer around the clad, and a secondary coating layer is formed of a UV-cured polymer around the primary coating layer, to a thickness ranging from about 22 to 37.5 mum in order to obtain a coating strip force ranging from about 1.0 to 1.63 N and a dynamic stress corrosion parameter ranging from 20 to 29. The primary and secondary coating layers can be formed by a wet on wet or wet on dry process.

Description

technical field [0001] The present invention generally relates to an optical fiber. More specifically, the present invention relates to a double-coated optical fiber and its coating peel force. Background technique [0002] In general, optical fibers include a core that provides a medium for transmission of light and a cladding surrounding the core to confine light within the core. A coating surrounds the cladding and serves to protect the interior of the fiber from the external environment. [0003] The coating is a very important component for determining the physical fiber properties such as bend, chemical resistance and mechanical strength. In order to measure the mechanical properties of the optical fiber, it is known in the art to perform a dynamic fatigue test and a coating layer peeling test to evaluate the quality of the optical fiber. [0004] Because optical fibers undergo physical changes due to external factors when they are used in real-world applications, d...
