20100260458 | OPTICAL FIBER CABLE HOLDER, FUSION SPLICER INCLUDING THE HOLDER, AND FUSION SPLICING METHOD USING THE HOLDER - A holder capable of holding an optical fiber cable without breaking or damaging the cable includes a holder main body, a fiber holding portion, and a cable holding portion. The main body has a groove for receiving the optical fiber exposed from the cable sheath at an end part of the cable, and a portion for receiving the end part of the cable sheath. A positioning surface with which an end surface of the cable sheath can come in contact is provided at the boundary between the fiber receiving groove and the cable receiving part. A fiber holding portion for pressing and holding the optical fiber received by the fiber receiving groove, and a cable holding portion for pressing and holding the cable sheath received by the cable receiving part, are configured so that holding by the cable holding portion is released in conjunction with the release of holding by the fiber holding portion. | 10-14-2010 |
20120201500 | SPLICED OPITCAL CABLE ASSEMBLY - A spliced optical cable assembly is reinforced at a spliced portion of coated optical fibers to have adequate strength. The spliced optical cable assembly includes: a pair of optical fiber cables in which high-strength fibers are aligned in the longitudinal direction around coated optical fibers. The outer circumference of the coated optical fibers being covered by sheaths. The spliced optical cable assembly further includes a connecting portion in which the pair of optical fiber cables are connected and the coated optical fibers extend from the sheaths. Glass fibers exposed from the coating of the coated optical fibers spliced to each other. The connected portion is covered and formed into an integral unit, together with the high-strength fibers exposed from the sheaths, by a reinforcing tube placed over the optical fiber cables and caused to contract so that both ends of the reinforcing tube engage the sheaths of the respective optical fiber cables. | 08-09-2012 |
20130230286 | HEATING DEVICE FOR OPTICAL-FIBER REINFORCEMENT, AND OPTICAL-FIBER FUSION SPLICING DEVICE - An optical fiber reinforcing heating device has a base part, to which a first lid part for covering a sleeve accommodation groove for containing a fiber reinforcement sleeve covering a fusion-splicing part of optical fibers is attached so as to be openable and closable. A pair of fiber holders for holding and securing the optical fibers are disposed on both end sides of the first lid part. Each fiber holder has a second lid part which is attached to a fiber container so as to be openable and closable and presses the optical fiber against the fiber container. A switch lever which is movable longitudinally of the sleeve accommodation groove is disposed on the upper face of the second lid part built in with a pin adapted to move in conjunction with the switch lever. A joint hole adapted to engage the pin is formed within the first lid part. | 09-05-2013 |
20130236146 | OPTICAL FIBER HOLDER AND OPTICAL FIBER FUSION-CONNECTING DEVICE - An optical fiber fusion splicer includes optical fiber holders that hold optical fibers. Each optical fiber holder includes a base, a cover, and a connecting portion. The base includes a setting table on which an optical fiber F is placed so as to be oriented in the longitudinal direction of the base. The cover has pressing members that press the optical fiber F placed on the setting table against the setting table. The connecting portion joins the cover to the base such that the cover is openable away from and closeable over the base and movable in the longitudinal direction of the base. | 09-12-2013 |
20130277356 | METHOD OF FUSION-SPLICING OPTICAL FIBERS AND FUSION SPLICER - A method of fusion-splicing includes attaching a stab to a stub cap having a non-axisymmetric structure, positioning an embedded optical fiber to a fusion splicing working part by fixing the stub cap thereto; positioning an outside optical fiber to the fusion splicing working part; fusion-splicing the embedded optical fiber and the outside optical fiber; repositioning the embedded optical fiber to a reinforcing working part by fixing the stub cap thereto and repositioning the outside optical fiber to the reinforcing working part such that a relative positional relationship between the embedded optical fiber and the outside optical fiber becomes the same as that at the fusion splicing working part; and reinforcing a spliced portion between the embedded optical fiber and the outside optical fiber while a tension is applied to the embedded optical fiber and the outside optical fiber. | 10-24-2013 |
20130284377 | OPTICAL FIBER FUSION-CONNECTING DEVICE - An optical fiber fusion-splicing device is equipped with a fusing unit disposed on a housing, which fuses optical fibers F to each other, and a windproof cover that prevents winds from entering the fusing unit. The windproof cover is provided with a blocking elastic body arranged so as to block, in cooperation with a blocking elastic body of the housing, an inlet for introducing the optical fiber F into the fusing unit, a bias spring that biases the blocking elastic body toward the blocking elastic body, and a transmission member that transmits a biasing force of the bias spring to the blocking elastic body. | 10-31-2013 |
