    摘要: An optical fiber fuse protection device includes an upstream optical fiber disposed on an upstream side, a downstream optical fiber disposed on a downstream side, and a wall interposed between a part of the upstream optical fiber and a part of the downstream optical fiber. The downstream optical fiber is fusion-spliced to the upstream optical fiber and is made of a single optical fiber or a plurality of optical fibers fusion-spliced to each other.

    摘要: An indexing terminal arrangement includes a terminal housing that receives an input cable; an optical power splitter disposed within the interior of the terminal housing; a first multi-fiber optical adapter coupled to the terminal housing; a first single-fiber optical adapter coupled to the terminal housing; and a pass-through multi-fiber optical adapter coupled to the terminal housing. Split optical signals are provided to the first multi-fiber optical adapter and the first single-fiber optical adapter. Unsplit and indexed optical signals are provided to the pass-through optical adapter.

    摘要: A field-assembly optical connector includes an inner sleeve module, a connector frame housing the inner sleeve module, and a cable boot coupled to the inner sleeve module to protect a sheath of an optical fiber. The inner sleeve module includes a sleeve body having a sleeve, an intermediate connector fitted on the sleeve body and having protrusions, a spring fitted on a threaded portion of the sleeve body, a fixing ring screwed to the threaded portion of the sleeve body, and a ferrule stub inserted into the sleeve body through the fixing ring. A cable boot is fixed to the sleeve body and is coupled to the intermediate connector to be moveable within a predetermined range.

    摘要: A splice holder tray has a splice holder section that includes a plurality of inclined channels. Each of the plurality of inclined channels includes a first portion presenting a cross section area that is measured on a reference plane, two opposite lateral openings, and a top opening and a bottom opening. The bottom opening has an area smaller than the cross section area.

    摘要: 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.
