Abstract: Provided are embodiments of an optical fiber cable. The optical fiber cable includes a cable jacket with an inner surface and an outer surface in which the inner surface defines a central cable bore and in which the outer surface defines an outermost surface of the optical fiber cable. The optical fiber cable includes from 48 to 864 optical fibers disposed within the central cable bore. Further, the outer surface of the cable jacket defines a cable diameter of at least 2 mm and up to 11 mm. The optical fiber cable has a fiber density of at least 7.5 optical fibers/mm2 based on a cross-sectional area of the optical fiber cable as measured from the outer surface of the cable jacket.

Abstract: Disclosed are embodiments of an optical fiber ribbon. In the optical fiber ribbon, subunits each include a subunit coating surrounding at least one optical fiber. Bonds are intermittently formed between adjacent subunits. Each bond has a unique longitudinal position along a length of the optical fiber ribbon such that no other bond is located at the unique longitudinal position. Each optical fiber includes a core region, a cladding region surrounding the core region, a primary coating surrounding the cladding region, and a secondary coating surrounding the primary coating. The cladding region defines a glass diameter in a range from 90 microns to 110 microns, and the secondary coating defines an outer diameter of 140 microns to 170 microns. The cladding region has a depressed index region comprising a trench volume of -20 %Δ-micron2.

Abstract: A system for maintaining relative position of separate fibers is provided. The system comprises a fiber holder and fibers extending parallel along a Z-axis. The fibers include a first and second fiber, both having a coating and a core section. The fiber holder has a first and second alignment slots. The first alignment slot defines a first recess in a first surface of the fiber holder. The first recess is configured to receive the first fiber therein to provide frictional resistance to the first fiber. The second alignment slot defines a second recess in the first surface. The second recess is configured to receive the second fiber therein to provide frictional resistance to the second fiber. The first alignment slot is positioned in a fixed spaced apart manner from the second alignment slot to maintain at least a relative position of the first fiber and the second fiber.

Abstract: A method, system, and computer program product for determining a core-to- ferrule offset of a ferrule for a fiber optic connector, A reference ferrule is physically aligned with a core imager by positioning the reference ferrule so that edges of the reference ferrule in a plurality of profile images are aligned with fiducial markers in the images. The reference ferrule is incrementally rotated about its longitudinal center access, a core image captured at each rotational angle, and a reference core-to-ferrule offset determined based on the core images. A test ferrule is physically aligned with the core imager by positioning the test ferrule so that edges of the test ferule are aligned with the edges of the reference ferrule in a plurality of profile images. The core-to-ferrule offset of the test ferrule is then determined based on an offset between the test and reference cores in a composite core image.

Abstract: An optical fiber cable that includes subunits is provided. Optical fiber cables are used to transmit data over distance. The subunits are twisted and stranded within the cable to reduce degradation of stranding during use of the cable. The subunits of one or more optical fiber cables are arranged in complimentary configurations that counteract their varying asymmetrical forces to provide an improved handling performance for the optical fiber cable.
