Patent number: 6556754Abstract: A three dimensional optical circuit featuring an optical manifold for organizing, guiding and protecting individual optical fibers is shown. One aspect of the present invention is a three dimensional manifold which may be constructed using a rapid prototyping process such as, but not limited to, stereolithography (“SLA”), fused deposition modeling (“FDM”), selective laser sintering (“SLS”), and the like. The manifold has a number of input openings in a first ordered arrangement at one end connected by passageways to a number of output openings in a second ordered arrangement at the opposite end. A plurality of optical fibers may be directed through the passageways of the manifold to produce a three dimensional optical circuit such as a shuffle. Moreover, the optical manifold may be used in conjunction with a number of connections or terminations to form a various optical modules. These modules may be configured for rack mounting within enclosures for electrical components.Type: GrantFiled: August 10, 2001Date of Patent: April 29, 2003Assignee: 3M Innovative Properties CompanyInventors: Richard L. Simmons, Curtis L. Shoemaker, Kenneth L. Kornele, Harry A. Loder, Edward B. Lurie

Patent number: 5458528Abstract: 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 an APC finish to a chamfered ferrule while maintaining the apex of the spherical end face on the fiber axis.Type: GrantFiled: June 28, 1994Date of Patent: October 17, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Edward B. Lurie, Raman K. Selli

Patent number: 5109983Abstract: A package for handling and shipping optical fiber jumpers which permit testing during manufacturing and by the end user, which package includes a sheet having allochiral halves each with cut-outs to form ears upon which to spirally wind a length of optical fiber having a connector plug formed on each end. The halves are folded together and subsequently the length of fiber bridging the fold line can be cut to provide two pigtails.Type: GrantFiled: January 28, 1991Date of Patent: May 5, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: James P. Malone, Warren J. Biskupek, Edward B. Lurie
