The axes of holding sleeves are the axes thereof, which avoids multiple holding sleeves from deviating each other due to assembly errors, and ensures that the ceramic sleeve may float freely within the holding sleeve.

In an aspect of the present disclosure, a submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body.

An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

The disclosure relates to an optical fiber connector and cable assembly that includes an optical fiber cable and an optical fiber connector, wherein the optical fiber cable has an optical fiber and a cable sheath, and a free end of the optical fiber is provided with a ferrule, and the ferrule is associated with a ferrule spring. The optical fiber connector includes a connector body and a cover; a first fixing sleeve and a second fixing sleeve, between which the cable sheath is anchored; an insert mounted at a distal end of the first fixing sleeve, having a passage for receiving a proximal section of the ferrule and supporting the ferrule spring. In a direction facing a distal end of the connector body, the cover presses a first fixing sleeve, the first fixing sleeve presses the insert, the insert presses the ferrule spring, and the ferrule spring presses the ferrule. The disclosure also relates to an optical fiber cable connection system including two optical fiber connector and cable assemblies to be connected to each other. The optical fiber connector and cable assembly may have relatively simple structure, easy assembly and reliable operation.

In some embodiments, the present disclosure is directed at an optical fiber connector that occupies a small volume, and can therefore fit into small optical modules. In some embodiments, the optical fiber connector may comprise a removable faceplate. During installation, the faceplate may be removed to allow an optical fiber plug with a flange to be placed within the optical fiber connector. The flange may comprise one or more spring tabs. The faceplate may then be re-attached to the optical fiber connector, wherein at least a portion of the faceplate engages with the flange and secures the optical fiber plug with the optical fiber connector. The one or more spring tabs may also engage with the removable faceplate, thereby holding the optical fiber plug in place so as to ensure proper light transmission from the fiber to an opposing fiber.

An optical fiber inspection system may include an alignment guide having a sleeve portion and a mechanical key structure. The sleeve portion may comprise a first opening arranged to be proximal to one or more optical components in an inspection device and a second opening arranged to be distal to the one or more optical components when the alignment guide is removably engaged with the inspection device. The mechanical key structure may be located adjacent to the second opening and have a shape to engage a geometry of one or more recesses in a bulkhead. Accordingly, the alignment guide may stabilize the inspection device at a particular angle relative to an end face of an object in a field of view of the one or more optical components when a shaft of the inspection device is inserted into the bulkhead.
