On-Line Sensor Systems for Monitoring the Cure of Coatings on Glass Optical Fibers and Assemblies

PDF Version Also Available for Download.

Description

Glass fiber technology, which enables light transmission and communication over great distances, was developed in the U.S. and has evolved into a major industry in this country. Continuous innovation is required to maintain the leadership position that the U.S. enjoys in glass optical fiber technology. This project addressed a key quality assurance aspect of glass optical fiber and cable assembly production-namely, assuring full cure of the polymer coating that protects the fiber from physical damage and moisture degradation. Properly cured coatings are imperative for the cable-assembly industry because they provide protection from the environment and assure both mechanical strength and ... continued below

Description

Glass fiber technology, which enables light transmission and communication over great distances, was developed in the U.S. and has evolved into a major industry in this country. Continuous innovation is required to maintain the leadership position that the U.S. enjoys in glass optical fiber technology. This project addressed a key quality assurance aspect of glass optical fiber and cable assembly production-namely, assuring full cure of the polymer coating that protects the fiber from physical damage and moisture degradation. Properly cured coatings are imperative for the cable-assembly industry because they provide protection from the environment and assure both mechanical strength and long-term performance of the cable assembly, The industry loses approximately 5% of its production due to under-cured fiber. This loss amounts to roughly $70,000,000 per year. The standard procedure in the industry is to spot check cables after production because no on-line method has been available to continuously monitor cure during either the glass-fiber drawing process, which operates at high speeds of roughly 1 kilometer per minute, or the cable-assembly process. Many kilometers of out-of-specification material can therefore be produced before tests catch the flaw. This project strove to eliminate this delay.
