20100158452 | METHOD CONNECTING OPTICAL FIBER OF OPTICAL CONNECTOR WITH OPTICAL TRANSMISSION ELEMENT, CONNECTOR-ATTACHED OPTICAL TRANSMISSION ELEMENT, OPTICAL CONNECTOR, AND ASSEMBLING METHOD OF OPTICAL CONNECTOR - A connection method connects an optical connector and an optical transmission element. The optical connector includes a connector housing, a stop-ring structure, and an optical fiber which protrudes from an end part of the stop-ring structure. The optical transmission element includes a tensile-strength fiber body. The connection method includes fuse-connecting a first end of the optical fiber with a second end of an optical fiber protruding from a transmission element terminal part of the optical transmission element; inserting a fuse-connected optical fiber part and the tensile strength fiber body inside a reinforcing sleeve provided with a hot melt body, and covering and bridging the transmission element terminal part and at least the end part of the stop-ring structure; and integrating the fuse-connected optical fiber part, the tensile strength fiber body, the transmission element terminal part, and the stop-ring structure, by a hot melt resin melted from the hot melt body. | 06-24-2010 |
20110217004 | DEVICE FOR BENDING OPTICAL FIBER AND RECEIVING LIGHT - A device for bending an optical fiber and receiving light is provided with a recessed holding member having a recess, a projecting holding member having a projection projecting toward the recess, light receiving elements for receiving leak light from an optical fiber held between the recess and the projection, and a supplemental support mechanism that is substantially independent of the recess or the projection and supplementarily supports the optical fiber between the recess and the projection such that the leak light from the optical fiber is received by center of the light receiving elements. | 09-08-2011 |
20110308358 | SHEATH REMOVING UNIT AND OPTICAL FIBER-SHEATH REMOVING DEVICE - A sheath removing unit according to the invention includes a sheath removing blade that includes a pair of blade bodies disposed so as to face each other, and an optical fiber guide that includes first guide body and the second guide body. The first guide body includes a first protruding portion that is disposed so as to be superimposed on a first blade body of the blade bodies and protrudes from the first blade body toward a second blade body. The second guide body includes a second protruding portion that is disposed so as to be superimposed on the second blade body and protrudes from the second blade body toward the first blade body. The first protruding portion includes a lower inclined portion, which is inclined outward toward a protruding direction of the first protruding portion, on the surface thereof facing the second guide body. The second protruding portion includes an upper inclined portion, which is inclined outward toward a protruding direction of the second protruding portion, on the surface thereof facing the first guide body. | 12-22-2011 |
20130126502 | DEVICE AND METHOD FOR APPLYING ELECTRIC DISCHARGE ON OPTICAL FIBER - A device for applying electric discharge on an optical fiber by electrodes is comprised of a first driving mechanism for controllably driving the electrodes in a first direction perpendicular to an axial direction of the optical fiber; and a second driving mechanism for controllably and synchronously driving the electrodes in a second direction perpendicular to the axial direction of the optical fiber but not identical to the first direction. | 05-23-2013 |
20130140290 | OPTICAL FIBER FUSION SPLICER - A device for applying electric discharge to an optical fiber is comprised of a pair of electrodes having the optical fiber interposed between the electrodes and being opposed to each other; a pedestal configured to support the electrodes; a member configured to securely press the electrodes onto the pedestal; and a heat radiation fin provided on the member. | 06-06-2013 |

20140044339 | FUSION SPLICER AND METHOD FOR DETERMINING AN OPTICAL FIBER TYPE - A fusion splicer includes an imaging unit configured to take a lateral transmission image by illuminating a target optical fiber from a lateral direction of the target optical fiber; a determination module configured to create a target luminance distribution in a direction perpendicular to an optical axis of the target optical fiber using the lateral transmission image so as to determine a type of the target optical fiber, by comparing the target luminance distribution with preliminarily registered data of a reference luminance distribution of a reference optical fiber; and a registration module configured to create a message when the target luminance distribution is determined to be outside a tolerance of the reference luminance distribution and to display the message to an operator so that the operator can decide whether or not to register the target luminance distribution of the target optical fiber as a new reference luminance distribution. | 02-13-2014 |
20140157830 | OPTICAL FIBER FUSION SPLICE SYSTEM - An optical fiber fusion splice system includes a working table and a storage box which stores the working table. The working table includes a fusion splicing machine installation portion accommodating a fusion splicing machine to be stored in the storage box and a working surface on which preparation work for an optical fiber is configured to be performed. The fusion splicing machine installation portion includes a fusion splicing machine restriction portion being configured to restrict the fusion splicing machine without the fusion splicing machine moving in a horizontal direction with respect to the working table. The working surface includes a protrusion provided on an outer circumference of the working surface, the protrusion being configured to prevent a tool used in the preparation work from falling from the working surface. The storage box includes a box main body and a cover which covers an upper portion of the box main body. | 06-12-2014 |
20150049991 | OPTICAL FIBER FUSION SPLICER - An optical fiber fusion splicer includes: a windshield cover that is formed so as to be openable and closable and that includes one or more cover members that cover a heat fusion portion in a closed state; a pair of fiber mounting portions that are provided on left and right sides of the heat fusion portion; a pair of fiber mounting detectors that are provided in the fiber mounting portions and that detect that an optical fiber has been mounted. Also, when both the fiber mounting detectors detect that the optical fibers have been mounted in a state where the cover member is open, an operation to close the cover member is performed, the fusion splice is performed, connection portion inspection is performed, and an operation to open the windshield cover is performed after the connection portion inspection is completed. | 02-19-2015 |
