A stacking feature may be configured to removably attach a second retainer assembly to the retainer assembly. The at least one retainer may be configured to releasably retain the one or more optical fibers to strain relief the one of more optical fibers. The mounting surface may be fiber optic equipment. The fiber optic equipment may be a shelf mounted to a chassis in a fiber optic equipment rack.

A support shelf for fiber optic hardware is disclosed. Generally, the support shelf includes a plurality of component mounting features that permits releasably mounting of fiber optic hardware at a plurality of locations on the support shelf. The component mounting features are generally openings in a base of the support shelf and may be slots in the base as well. With this improved configuration, fiber optic hardware such as adapter panels can be mounted at a variety of locations on the support shelf ranging from flush with a front edge of the support shelf to a recessed mounting, which is a distance from the front edge.

Movable adapter panel

There is provided fiber drop terminal ('FDT') assemblies for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDT assemblies include a base and a cover that define a tongue and groove that selectively engage to seal the base and cover. The FDT assemblies also include a mounting plate for mounting of the base and cover, as well as a mounting plate extension for mounting of a skirt. The skirt provides slack storage for drop cables exiting the FDT. The components of the FDT assembly are selectively interlockable to prevent unauthorized access to the interior cavity of the base and cover and to the slack storage area of the skirt.

Fiber optic terminal assembly

A multi-layer module that includes a multi-fiber cable storage layer having a cable entry opening and a cable winding structure is disclosed. Also included is a splice storage layer that is discrete from the multi-fiber cable storage layer, the splice storage layer having a splice layer receiving opening in communication with the multi-fiber cable storage layer and a slack storage area. The multi-layer module includes a pigtail storage layer that is discrete from both the multi-fiber cable storage layer and the splice storage layer, the pigtail storage layer having a pigtail connector area and a pigtail storage area, the pigtail storage area comprising a pigtail storage layer receiving opening in communication with the splice storage layer.

Multi-layer module

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.

Multi-configurable splice holder

A compact optical splitter module is disclosed. One type of compact optical splitter module is a planar attenuated splitter module that includes a branching waveguide network having j&#x2267;1 50:50 splitters that form up to n&#x2266;2output waveguides having associated n output ports, wherein only m&#x3c;n output ports are suitable for transmitting light to the at least one external output device. This provides a 1&#xd7;m splitter module wherein each output port has the attenuation of a 1&#xd7;n splitter module, thereby obviating the need for external attenuation. Another type of compact optical splitter module is a direct-connect splitter module that eliminates the need for an optical fiber array when coupling to external optical fibers. Another type of compact optical splitter module is a microsplitter module that serves as device and module at the same time and that eliminates the differentiation between device and module. The integration of device and module also makes manufacturing the microsplitter module cost-effect. Embodiments of microsplitter modules that account for differences in the coefficient of thermal expansion of the materials making up the microsplitter are also disclosed.

A polymer based index-matching gel for use with nanostructure optical fibers is disclosed. The index-matching gel has at least one polymer component having a viscosity &#x3b7; at 25&#xb0; C. of 3 Pa-s&#x2266;&#x3b7;&#x2266;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.

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.

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.
