METHOD FOR POLISHING FIBER OPTIC FERRULES

Title:

METHOD FOR POLISHING FIBER OPTIC FERRULES

Document Type and Number:

WIPO Patent Application WO/1995/000870

Kind Code:

A1

Abstract:

A method of polishing ferrules used in optical fiber connectors centers the apex of the spherical end face of the ferrule on the fiber axis. The invention is directed to ferrules whose ends are angled and generally spherical, providing angled physical contact (APC) between a pair of interconnected fibers. These ferrules commonly have a chamfer from the outermost diameter leading to the spherical, angled end face. In such prior art ferrules, the apex of the spherical end face does not coincide with the fiber axis, leading to a potential gap between the fiber ends which affects several performance factors, including insertion loss, stability and repeatability. The present invention provides several practical methods for imparting and APC finish to a chamfered ferrule while maintaining the apex of the spherical end face on the fiber axis.
