摘要： In various examples, a fiber-optic-splice enclosure may be suitable for use in various applications, environments, and use conditions. In at least some embodiments, the fiber-optic-splice enclosure includes an adjustable length, which may permit the fiber-optic-splice enclosure to be customized to fit various lengths of a spliced region. In a further aspect, the fiber-optic-splice enclosure may include a splice retainer to attenuate vibrational and other forces and reduce potential effects of those forces on the splice. Moreover, in some other aspects, the construction of the fiber-optic-splice enclosure may allow for relatively straightforward and efficient assembly. For example, a key and keyway configuration between different components of the fiber-optic-splice enclosure may permit the components to selectively slide relative to one another or be engaged to one another.

摘要： A multi-fiber cable assembly includes a pigtail segments spliced to a trunk segment using multiple mass fusion splices. The splices are disposed at axially spaced positions within a hollow, flexible conduit. Fibers of the trunk segment are axially fixed at a first demarcation region disposed at the first end of the conduit. Fibers of the pigtail segments are axially fixed at a separate, second demarcation region disposed at the second end of the conduit.

摘要： A fusion splicer management system for managing progress of a fusion splicing work performed by each splicing technician by using a fusion splicer. This management system includes an acquisition unit, a determination unit, and a notification unit. The acquisition unit acquires fusion splicing data regarding the fusion splicing work performed by each splicing technician who uses each fusion splicer whenever each fusion splicing work is performed. The determination unit determines a progress status of each fusion splicing work by comparing the fusion splicing data with work plan data indicating a work plan. The notification unit notifies of the progress status of each fusion splicing work determined by the determination unit.

摘要： An object is to be capable of housing an optical fiber that connects between components not to exceed a bending limit of the optical fiber in a housing of a pluggable optical module. A pluggable electric connector (11) is configured to be insertable into and removable from an optical communication apparatus (93). An optical output module (12) outputs an optical signal (LS1) and a local oscillation light (LO). An optical reception module (13) outputs a communication data signal (DAT) generated by demodulating using the local oscillation light (LO). A pluggable optical receptor (15) is configured in such a manner that optical fibers are insertable thereinto and removable therefrom. A first optical fiber (F11) is connected between the optical output module (12) and the pluggable optical receptor (15). A second optical fiber (F12) is connected between the optical output module (12) and the optical reception module (13). A third optical fiber (F13) is connected between the optical reception module (13) and the pluggable optical receptor (15). Optical fiber housing means winds extra lengths of the first to third optical fibers (F11 to F13) around a guide.

摘要： An optical fiber alignment method makes it possible to reduce the time required for alignment work for an optical fiber. This alignment method includes: an image acquisition step of acquiring an end surface image of an optical fiber; a measurement step of measuring arrangement data relating to a plurality of elements from the end surface image; a calculation step of calculating an amount of deviation of each of the plurality of elements from a target element arrangement from a correspondence relationship of the elements between the obtained arrangement data and reference arrangement data for element identification recorded in advance; and an alignment step of rotating the optical fiber around a central axis such that the obtained amount of deviation is reduced.

摘要： A mounting system (700/900) for locking two pieces of telecommunications equipment (610/810) to prevent relative sliding therebetween and relative separation therebetween in a direction generally perpendicular to the direction of the relative sliding includes a first locking feature (701/901) defined by a stud (702/902) with a stem portion (708/908) and a flange portion (710/910) having a larger profile than the stem portion (708/908) and a second locking feature (703/903) defined by a slot (704/904) with a receiver portion (712/912) and a retention portion (714/914). The receiver portion (712/912) is sized to accommodate the flange portion (710/910) of the stud (702/902) and the retention portion (714/914) is sized to accommodate the stem portion (708/908) but not the flange portion (710/910) of the stud (702/902). A third locking feature (705/905) prevents relative sliding between the two pieces of telecommunications equipment (610/810) once the stud stem portion (708/908) has been slid within the slot retention portion (714/914) and the stud flange portion (710/910) is out of alignment with the slot receiver portion (712/912).
