Publication number: 20220276440Abstract: A fusion splicing device includes a fusion splicing unit, a fusion splicing control unit, an imaging unit, and a notification unit. The fusion splicing unit fusion-splices optical fibers by discharge between a pair of electrode rods. The fusion splicing control unit controls an operation of the fusion splicing unit and has an operation mode for performing a discharge test. The imaging unit generates image data of a fusion spliced portion of the optical fibers. The notification unit notifies various kinds of information. The discharge test is to fusion-splice the optical fibers, to check a fusion-spliced state of the optical fibers on the basis of the image data, and to adjust a fusion splicing condition to be close to an optimum condition. When a predetermined start condition is satisfied, the fusion splicing control unit causes the notification unit to notify information for requesting execution of the discharge test.Type: ApplicationFiled: August 19, 2020Publication date: September 1, 2022Applicant: SUMITOMO ELECTRIC OPTIFRONTIER CO., LTD.Inventors: Kazuyoshi OOKI, Makoto MIYAMORI, Hideaki YUSA
