Publication number: 20100054686Abstract: Furcation management structures and fiber optic shelf assemblies including one or more furcation management structures are disclosed. The furcation management structures are disposed in a chassis of a fiber optic shelf assembly and define a mounting surface for mounting at least one furcation body of a fiber optic cable assembly thereto. The furcation management structure may allow the fiber optic shelf assemblies to provide a greater density of fiber optic cable assemblies to support high density fiber optic equipment. Moreover, the furcation management structures provides the craft with an organized mounting structure that is relatively quick and easy to remove, rearrange, and/or reconfigure.Type: ApplicationFiled: April 2, 2009Publication date: March 4, 2010Inventors: Terry L. Cooke, David L. Dean, JR., Tory A. Klavuhn, Manuel Alejandro Lopez Sanchez, Harley J. Staber

Publication number: 20100051886Abstract: Pulling grip housing assemblies for a fiber optic assembly are disclosed. In one embodiment, the pulling grip assembly is comprised of a pulling grip housing for receiving part of a fiber optic assembly. A pulling grip sleeve is also provided. The pulling grip sleeve has at least one sleeve locking feature suitable for cooperating with a housing locking feature of the pulling grip housing to secure the pulling grip housing to the pulling grip sleeve. In this manner, the pulling grip housing can easily be secured to the pulling grip sleeve and removed when pulling of a fiber optic assembly is completed. The pulling grip housing and pulling grip sleeve can also be reused for pulling other fiber optic assemblies.Type: ApplicationFiled: November 26, 2008Publication date: March 4, 2010Inventors: Terry L.

Publication number: 20100052346Abstract: Pulling grips for installing a fiber optic assembly are disclosed. The pulling grip includes a pulling grip housing for receiving part of a fiber optic assembly therein. The pulling grip may also include a pulling grip sleeve and/or pulling sock. In one embodiment, the pulling grip housing has a friction fit with the pulling grip sleeve when assembled, thereby inhibiting rotation therebetween. Consequently, the friction fit advantageously inhibits twisting of the fiber optic assembly when installing the same using the pulling grip. In this manner, the pulling grip housing can easily be insert into the pulling grip sleeve and removed when pulling of a fiber optic assembly is completed. The pulling grip housing, pulling grip sleeve, and/or pulling sock may also be reused for pulling other fiber optic assemblies.Type: ApplicationFiled: June 19, 2009Publication date: March 4, 2010Inventors: Terry L. Cooke, David L. Dean, JR., Tory A. Klavuhn

Publication number: 20100054684Abstract: A fiber optic apparatus having a fiber optic equipment tray and an extension adapted to receive, organize and manage fiber optic cables routed to the fiber optic equipment tray is disclosed. The fiber optic equipment tray has a front, a rear, a base, and at least one extension rail. The extension movably attaches to the fiber optic equipment tray at the extension rail and, thereby, slidably extends from and retracts toward the rear of the fiber optic equipment tray. The extension comprises a shelf and a cable management tray hingedly attached to the shelf. The shelf moves over the base when the extension extends from and retracts toward the fiber optic equipment tray. The cable management tray is in planer alignment with the fiber optic equipment tray when the extension is retracted, and allowed to pivot downwardly when the extension is extended. At least one furcation plug tray attaches to the cable management tray.Type: ApplicationFiled: February 27, 2009Publication date: March 4, 2010Inventors: Terry L. Cooke, Tory A. Klavuhn, David L.

Publication number: 20100054685Abstract: Embodiments disclosed in the detailed description include a telescoping fiber optic module. The telescoping fiber optic module may be provided in a fiber optic equipment chassis which may be disposed in an equipment rack to support fiber optic connections. In embodiments disclosed herein, the telescoping fiber optic module is comprised of a fixed housing portion having an opening on a front side defining a passage inside the fixed housing portion. The fiber optic module is also comprised of a telescoping portion received in the passage inside the fixed housing portion. In this manner, the telescoping portion can telescope in and out of the fixed housing portion. This allows fiber optic connectors or adapters disposed in the telescoping portion and any connections made thereto to be telescoped out for improved access and telescoped back into the fixed housing portion when access is no longer needed.Type: ApplicationFiled: March 31, 2009Publication date: March 4, 2010Inventors: Terry L.

Patent number: 7660504Abstract: Connectorized nano-engineered optical fibers and method for forming them are disclosed. The methods include heating a mid-span bare fiber portion of the nano-engineered fiber to substantially collapse the airlines therein so as to form a substantially airline-free portion. The fiber is then inserted into a ferrule channel so that the fiber end protrudes beyond the ferrule end face, but with the substantially airline-free portion positioned at the ferrule end face. The fiber is then cleaved at or near the ferrule end face in the substantially airline-free portion, and the new fiber end face polished to create a solid fiber end face that coincides with the ferrule end face. The methods result in relatively small changes to the mode field diameter (MFD) and/or to the outer cladding diameter.Type: GrantFiled: July 23, 2008Date of Patent: February 9, 2010Assignee: Corning Cable Systems LLCInventors: Robert R. Beshears, Dana C. Bookbinder, Terry L. Cooke, John B. Johnson, Dennis M. Knecht, Ming-Jun Li, Michael H. Rasmussen

Publication number: 20090180737Abstract: Optical fiber interconnection devices, which can take the form of a module, are disclosed that include an array of optical fibers and multi-fiber optical-fiber connectors, for example, two twelve-port connectors or multiples thereof, and three eight-port connectors or multiples thereof. The array of optical fibers is color-coded and is configured to optically interconnect the ports of the two twelve-port connectors to the three eight-port connectors in a manner that preserves transmit and receive polarization. In one embodiment, the interconnection devices provide optical interconnections between twelve-fiber optical connector configurations to eight-fiber optical connector configurations, such as from twelve-fiber line cards to eight-fiber line cards, without having to make structural changes to cabling infrastructure. In one aspect, the optical fiber interconnection devices provide a migration path from duplex optics to parallel optics.Type: ApplicationFiled: March 20, 2008Publication date: July 16, 2009Inventors: William R.
