20100014815 | FERRULE, AND METHOD OF PRODUCING AN OPTICAL WAVEGUIDE CONNECTOR, AND OPTICAL WAVEGUIDE CONNECTOR WHICH USE THE FERRULE - A method of producing an optical waveguide connector in which the productivity of a ferrule member can be improved, and the connection loss with a counter connector can be suppressed to a low level is obtained. | 01-21-2010 |
20100044406 | OPTICAL FIBER CUTTING APPARATUS AND OPTICAL FIBER CUTTING METHOD - There are provided an optical fiber cutting method and a cutting apparatus which can easily cut a coated optical fiber without a step of removing a coating from the optical fiber. It includes a clamp which holds the coated optical fiber, having a glass fiber and the coating, on both sides of a portion-to-be-cut, a disk-shaped blade member which moves at the portion-to-be-cut in a direction orthogonal to an axis of the optical fiber to cut the coating and to provide a slit into the glass fiber, and a support which presses, with a predetermined pressing force, the portion-to-be-cut from an opposite side of the blade member with respect to the portion-to-be-cut when cutting the coating and providing the slit into the glass fiber. A head of the support is formed with a groove along a sliding direction of the blade member. | 02-25-2010 |
20100098382 | OPTICAL MODULE AND CABLE UNIT PROVIDED WITH OPTICAL MODULE - Operation efficiency can be dramatically improved and a smaller configuration can be obtained by simplifying the optical connection. An optical module has an electrical connector to connect a device; an optical element unit being electrically connected to the electrical connector and provided with optical elements to convert electrical signals and optical signals and emitting or receiving light; an optical ferrule, having a plurality of optical fiber insertion holes, to hold optical fibers inserted into the plurality of optical fiber insertion holes so as to allow the fibers to be optically connected to the optical element; and an optical cable inlet to introduce an end part of an optical cable provided with the optical fibers. The cable unit with an optical module has an optical cable that includes a plurality of optical fibers and an optical module provided at two ends of the optical cable. | 04-22-2010 |
20100108868 | OPTICAL MODULE - An optical module is configured such that it is not susceptible to fine particulate matter when an optical fiber is inserted into a fiber insertion hole thereof. The optical module is also configured to prevent any reduction in the optical coupling efficiency and degradation of anti-noise properties with the optical fiber. The optical module includes: a ferrule, having the fiber insertion hole formed on an end surface on which an electrical circuit is formed; a photoelectric conversion element, connected to the electrical circuit and facing the fiber insertion hole; and an optical fiber, optically coupled directly with the photoelectric conversion element. The optical fiber has a glass fiber and a protective coating, and is aligned with the insertion hole with the protective coating interposed therebetween. The optical fiber is retained in the insertion hole with the glass fiber not in contact with the insertion hole. | 05-06-2010 |
20100187276 | OPTICAL FIBER CUTTING DEVICE, OPTICAL FIBER CUTTING METHOD, AND OPTICAL FIBER CUTTING BLADE MEMBER - An optical fiber cutting device and method, and optical fiber cutting blade member in which excellent workability is obtained by a simple configuration, and a cost reduction can be attained are provided. | 07-29-2010 |
20100220960 | OPTICAL CONNECTOR, METHOD OF ATTACHING THE OPTICAL CONNECTOR TO COATED OPTICAL FIBER, AND OPTICAL CONNECTION MEMBER - An optical connector in which works of attaching an incorporated optical fiber to a ferrule, removing a coating of the tip end side of a coated optical fiber, and attaching an optical connector to the coated optical fiber can be made more efficient, and the transmission characteristics can be prevented from being lowered in the optical connector, and a method of attaching the optical connector to a coated optical fiber are provided. | 09-02-2010 |
20100284654 | OPTICAL CONNECTING MEMBER AND METHOD OF FITTING THE SAME - To provide an optical connecting member capable of positioning and connecting a coated fiber by a simple connecting work with high precision, and a method of fitting the same. | 11-11-2010 |
20110194820 | OPTICAL MODULE AND METHOD OF ASSEMBLING THE SAME - An optical module is obtained in which a photoelectric converting element can be fixed by a highly reliable resin material while the resin material can be prevented from intruding into an optical path and the transparency of the optical path is ensured. | 08-11-2011 |
