20080232744 | Multifiber ferrule with precision bumpers and methods for making the same - A multifiber (MF) ferrule produced using a ferrule molding insert that is jig ground in order to improve the tolerance on the bumper height of a molded ferrule and the surface finish on the region of interest (ROI), thus improving manufacturing yields. | 09-25-2008 |
20080304796 | Connectorized nano-engineered optical fibers and methods of forming same - 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. | 12-11-2008 |

20120082419 | POLISHING JIG, FERRULE, AND OPTICAL CONNECTOR - A polishing jig | 04-05-2012 |
20120263422 | Methods for Processing a Multi-Fiber Ferrule - A method for processing ferrules for fiber optic connectors is disclosed herein. The method involves ablating a distal end face of the ferrule with the plurality of laser beam pulses to remove a distal layer of the ferrule without removing an optical fiber secured within the ferrule. By removing the distal layer from the ferrule, the optical fiber is caused to protrude distally outwardly from the distal end of the ferrule by a desired amount. | 10-18-2012 |
20130343710 | SIMULTANEOUS THERMAL FORMING OF FERRULE AND OPTICAL FIBER IN A FERRULE ASSEMBLY TO THERMALLY FORM AN OPTICAL SURFACE IN THE FERRULE ASSEMBLY, AND RELATED FIBER OPTIC COMPONENTS, FIBER CONNECTORS, ASSEMBLIES, AND METHODS - Simultaneous thermal forming of a ferrule and optical fiber as part of a ferrule assembly to thermally form an optical surface in the ferrule assembly. Related fiber optic components, connectors, assemblies, and methods are disclosed. In certain embodiments, the ferrule assembly is comprised of a ferrule and an optical fiber having an end portion extending from an end face of the ferrule. The ferrule may be made from a material or material composition having the same or similar thermal energy absorption characteristics as the optical fiber disposed in the ferrule. Thus, when the end face of the ferrule and an end portion of an optical fiber are simultaneously exposed to a wavelength(s) of a laser beam emitted by a laser, at least a portion of the end face of the ferrule and end portion of the optical fiber are both thermally formed together to form an optical surface. | 12-26-2013 |

The optical fiber and first sub-assembly can be routed through a structure (e.g., a building) prior to installation of the second sub-assembly. The second sub-assembly interlocks with the first sub-assembly to inhibit relative axial movement therebetween. Example first sub-assemblies include a ferrule, a hub, and a strain-relief sleeve that mount to an optical fiber. Example second sub-assemblies include a mounting block; and an outer connector housing forming a plug portion. | 03-03-2016 |
20160187592 | METHOD OF LASER POLISHING A CONNECTORIZED OPTICAL FIBER AND A CONNECTORIZED OPTICAL FIBER FORMED IN ACCORDANCE THEREWITH - Laser polishing is achieved by directing laser beam perpendicular at the fiber end face in a connectorized optical fiber having a metal ferrule. The spot size of the laser beam is larger than the bare optical fiber diameter, providing a more uniform spatial distribution of the radiation energy over the fiber end face. The metal ferrule provides heat conduction to prevent excessive heat built up at the fiber tip, which would lead to undesirable surface defects and geometries. The connectorized optical fiber may be pre-shaped prior to laser polishing. Subsequent laser polishing flattens the fiber end face. | 06-30-2016 |
