Patent number: 8867876Abstract: An optical fiber splitter has a higher density fiber optic array that allows for smaller packaging. The optical fibers that extend from the optical fiber splitter have one end connectorized and their spacing at the other end reduced, thereby eliminating components that were heretofore required. A method of making the fiber optic array includes interleaving the optical fibers to reduce the overall dimensions of the fiber optic array and the fiber optic splitter. A tool is used to reduce the spacing of the optical fibers in the fiber optic array.Type: GrantFiled: November 12, 2009Date of Patent: October 21, 2014Assignee: Corning Cable Sytems LLCInventors: Costas Saravanos, Elli Makrides-Saravanos, Otto I.

Patent number: 7277614Abstract: A tether assembly includes a tether cable containing optical fibers and adapted to be attached to a fiber optic distribution cable at a mid-span access location. A furcation at the end of the tether cable separates and transitions the optical fibers into furcation legs terminating in individual connector ports. Each connector port may be a receptacle for receiving a connector mounted upon one of the optical fibers and a mating connector of a drop cable, a plug mounted upon one of the optical fibers that is received within a plug alignment member operable to align the plug with a mating plug of a drop cable, or a connector that is routed to a receptacle disposed within an external wall of a network connection terminal from within the enclosure. The tether assembly provides a distribution cable assembly and method for mitigating a span length measurement difference in a pre-engineered communications network.Type: GrantFiled: December 3, 2004Date of Patent: October 2, 2007Assignee: Corning Cable Systems LLCInventors: Joseph T.

Patent number: 6742936Abstract: A method for assembling a population of ferrules to minimize the eccentricity of the fibers typically includes the steps of selecting a set of ferrules, determining the eccentricity of the ferrules, selecting a fiber, inserting the fiber within the ferrule bore, orienting the fiber within the ferrule, and securing the fiber in place. The result is a population of ferrules that can be mated with little or no insertion loss.Type: GrantFiled: November 6, 2000Date of Patent: June 1, 2004Assignee: Corning Cable Systems LLCInventors: Dennis M.

Patent number: 6396993Abstract: The challenge of pulling an optical fiber having a connector at its terminal end without incurring damage to the fiber or connector due to excessive pulling or bending is met by introducing a breakaway feature that disconnects the connectorized fiber from the pulling mechanism upon detecting excessive force. The breakaway feature may be positioned at several locations along the pathway connecting the optical fiber and the pulling force. In one embodiment the breakaway feature is disposed on a cover over the connectorized front end of the optical fiber. In other embodiments the breakaway element is inserted along the cord connecting the connectorized optical fiber to the pulling force.Type: GrantFiled: December 30, 1999Date of Patent: May 28, 2002Assignee: Corning Cable Systems LLCInventors: Markus A.

Patent number: 6044193Abstract: The fiber optic interconnection enclosure, such as a fiber optic distribution frame or the like, effectively limits the entry of particles, such as dust and other contaminants, into the enclosure. For example, the fiber optic interconnection enclosure can maintain a greater pressure, i.e., a positive pressure, within the internal cavity defined by the enclosure than outside of the internal cavity so as to effectively limit the entry of particles into the internal cavity, even as the door of the fiber optic interconnection enclosure is repeatedly opened and closed. The fiber optic interconnection enclosure generally includes at least one fan to draw air into the internal cavity through an air inlet port defined by the cabinet and to circulate the air through the internal cavity in order to reduce the number of particles that settle upon or are transferred to the end faces of the optical fibers or other surfaces within the internal cavity.Type: GrantFiled: July 10, 1998Date of Patent: March 28, 2000Assignee: Siecor Operations, LLCInventors: Otto I.

Patent number: 5748819Abstract: An optical fiber connector includes a longitudinally extending ferrule having fusion access means defined therein such that an optical fiber stub and a second optical fiber can be fused in the field during installation of the optical fiber connector. In one embodiment, the fusion access means includes a fusion access slot which extends transversely across the ferrule from a first side of the ferrule to a bottom portion of the fusion access slot such that a bore defined longitudinally through the ferrule opens into the fusion access slot. In this embodiment, the radial distance between the bottom portion of the fusion access slot and the second side of the ferrule, opposite the first side, is greater than a predetermined radial distance such that the fusion access slot does not significantly weaken the ferrule so that the ferrule remains structurally intact during use.Type: GrantFiled: April 5, 1995Date of Patent: May 5, 1998Assignee: Siecor CorporationInventors: Otto I. Szentesi, Rodney A. Throckmorton
