May 10, 2005

Appl. No.:

11/126778

Inventors:

Michael Heath Rasmussen - Keller TX, US

Assignee:

Corning Incorporated - Corning NY

International Classification:

G02B 6/04
G02B 6/02

US Classification:

385115, 385126

Abstract:

The present invention relates to fiber bundles and methods for making fiber bundles. According to one embodiment of the invention, a fused fiber bundle has a terminal section ending with an endface, and includes a plurality of optical fibers, each of the optical fibers having a terminal segment ending with a proximal end, and a distal end; and a cellular holding structure, the cellular holding structure including a cellular web portion having a plurality of longitudinal cells arranged substantially in parallel and surrounded by a web material; and a tube portion surrounding the cellular web portion. The terminal segments of the optical fibers are arranged substantially in parallel, and the terminal segment of each optical fiber is disposed in a longitudinal cell of the cellular holding structure and substantially fused to the web material, thereby forming the terminal section of the fused fiber bundle.

US Classification:

385125, 977762

Abstract:

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 collapse the airlines therein so as to form an 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 airline-free portion positioned at the ferrule end face. The fiber is then cleaved at or near the ferrule end face in the 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 at most only minimal changes to the mode field diameter (MFD) and/or to the outer cladding diameter, which is essential in forming a connectorized nano-engineered fiber that can connect to like-size nano-engineered or non-nano-engineered fibers.

Abstract:

A polymer based index-matching gel for use with nanostructure optical fibers is disclosed. The index-matching gel has a viscosity η at 25 C. of 3 Pa-s≦η≦100 Pa-s, which prevents the index-matching gel from wicking into the voids and down the nanostructure optical fiber to a depth where the fiber performance and/or device performance is compromised. The gel is suitable for use when mechanically splicing optical fibers when at least one of the optical fibers is a nanostructure optical fiber. The gel is also suitable for use in fiber optic connectors wherein at least one of the optical fibers constituting the connection is a nanostructure optical fiber.

Abstract:

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.

Abstract:

Splice holders for managing and storing splices between optical fibers in fiber optic hardware and equipment are disclosed herein. The splice holder include a base portion and an array of splice holding partitions extending from the base portion. In some embodiments the array of splice holding partitions define a plurality of rows for receiving a respective first splice component along a first direction and a plurality of columns intersecting the plurality of fiber rows for receiving a second splice component along a second direction. Similarly, in some embodiments, selected pairs of splice holding partitions define a column width and selected pairs of splice holding partitions define a row width. Additionally, in some embodiments, the column width is sufficiently greater than the row width to accommodate the second splice component oriented along one of the plurality of columns that could not otherwise be accommodated if oriented along one of the plurality of rows.
