摘要:
A polishing assembly and method for polishing optical cables, the polishing assembly having a platform configured to receive a polishing film and configured to rotate according to a dual orbital motion; a force gauge functionally coupled to the platform and configured to measure downward force applied against the platform; a mounting fixture configured to mount a plurality of optical cables; and a movable arm configured to move the mounting fixture downwards to press mounted cables against the polishing film, upwards to pull the mounted cables away from the polishing film, and to rotate circularly along a continuous circular path. The optical cables are pressed against the rotating polishing film while simultaneously monitoring the downward force applied against the platform so that downward force can be maintained within a prescribed tolerance throughout the polishing process.

Devices and methods for optical-fiber processing for connector applications are disclosed, wherein the devices and methods utilize a quantum cascade laser operated under select processing parameters to carry out end face polishing. The method includes supporting the optical fiber in a ferrule so that a bare end section of the fiber protrudes from an end of the ferrule by a protrusion distance. The method then includes irradiating the end face with light from the quantum cascade laser to polish the end face. The quantum cascade laser can also be used to form a bump in a central portion of the end face, wherein the bump facilitates physical contact between respective end faces of connected optical fibers.

[PROBLEMS] To provide an electron beam assisted EEM method that can realize ultraprecision machining of workpieces, including glass ceramic materials, in which at least two component materials different from each other in machining speed in a machining process are present in a refined mixed state and the surface state is not even, to a surface roughness of 0.2 to 0.05 nm RMS. [MEANS FOR SOLVING PROBLEMS] The EEM method comprises a working process in which a workpiece and chemically reactive fine particles are allowed to flow along the working face to remove atoms on the working face chemically bonded to the fine particles together with the fine particles through chemical interaction between the fine particles and the working face interface. The workpiece comprises at least two component materials present in a refined mixed state and different from each other in machining speed in the machining process. After the exposure of the workpiece in its working face to an electron beam to conduct modification so that the machining speed of the surface layer part in the working face is substantially even, ultraprecision smoothening is carried out by working process.

A polishing apparatus for an optical fiber connector (10) that includes an optical fiber ferrule (14) and a connector housing (30), comprises a polishing puck (110) having an aperture (113) to permit passage of the ferrule therethrough and a mount (114) to hold the connector housing at a predetermined angle. The polishing apparatus further includes a stabilizer (120) having a first portion mountable on the polishing puck to provide a grip separate from the connector housing. The polishing apparatus further includes a weighting device (130), at least a portion of which is disposed in the stabilizer, to provide a direct force on the connector housing, substantially independent from the stabilizer. The polishing apparatus provides a hand-polishing tool that controls the force and tilt placed on a terminated optical fiber connector during the polishing process, thereby providing more repeatable polished ferrules with respect to ferrule geometry such as ferrule radius of curvature (ROC), apex offset, and fiber height.

Apparatus for cutting an industrial-size roll of paper or other sheet material into two or more rolls. The apparatus includes a circular saw with a radius large enough to cut through such a roll in a single cut, leaving press-ready rolls that require no finish-trimming on the ends. The saw blade is mounted in a saw frame that travels along a carriage and positions the blade at any desired cutting position on the roll. The apparatus includes a support bed and load-bearing arms for supporting the weight of a large roll and keeping it in position during the cutting operation. Load/unload tables and a system of kicking cylinders guide the roll onto and off of the support bed. The saw frame is a tower that positions the saw blade above the roll at the desired cutting position, or a floor frame that positions the saw along side or beneath the roll at the desired cutting position. The apparatus further includes a finishing station for sanding the ends of cut rolls.

Eine Schleifvorrichtung (10) zum Schleifen von Körpern, insbesondere Ferrulen von optischen Steckverbindern, weist eine Vorrichtung (31) zur Aufnahme der zu schleifenden Körper auf, die entlang einer Achse (34) mit einer vorgebbaren Anpresskraft (F) gegen Schleifmittel gepresst werden kann, die in einer quer zur Achse (34) liegenden Schleifebene (32) angeordnet sind. Bei einer solchen Schleifvorrichtung wird bei einfachem Aufbau eine hohe Präzision dadurch erreicht, dass die Aufnahmevorrichtung (31) in der Achse (34) mittels einer Parallelogrammführung (30) geführt ist.
