An optical network comprises a fiber distribution cable and a terminal assembly. The terminal assembly receives a plurality of optical fibers from the fiber distribution cable and distributes one or more individual fibers to one or more single fiber bare-fiber holders that hold and protect each single fiber prepared and configured for splicing via an individual splicing element. The splicing element includes an alignment mechanism having a base plate and a clamp plate. At least one of the base plate and clamp plate is formed from a silica material and at least one of the base plate and clamp plate includes an alignment groove or channel configured to receive the first and second optical fibers in an end-to-end manner. The splice element also comprises an optical adhesive disposed in at least a portion of the alignment groove, wherein the optical adhesive is curable via actinic radiation.

An optical fiber holder includes: a holder body including an accommodating portion, the accommodating portion being configured to accommodate a plurality of optical fibers in a state in which the plurality of optical fibers are arranged in parallel; and a first lid portion configured to be opened and closed relative to the holder body and cover at least a part of the accommodating portion. The accommodating portion includes a pitch conversion portion having a plurality of ridge portions arranged in parallel and a plurality of flat bottom portions between the plurality of ridge portions. The plurality of ridge portions have a uniform height of 0.1 mm or less from the bottom portions, and parallel intervals in between enlarge or lessen from one side toward the other side in a longitudinal direction.

A holder includes a base including a reference surface and a slider to which an optical-fiber retainer that retains an optical-fiber can be attached. The slider is movable in a front-rear direction with respect to the base, and at least a portion of the optical-fiber retainer is accommodated between the reference surface and the slider when the optical-fiber retainer is attached to the slider and the optical-fiber retainer is positioned with respect to the reference surface by moving the slider toward a reference surface side.

A fiber holding tool and a fiber spacing adjustment method, which comprises a body and a cover, among which, the body and the cover are pivotally connected by a rotating shaft, and the body comprises a fiber accommodating groove used to accommodate the fiber, wherein, the fiber holding tool comprises a spacing conversion portion that can be rotated relative to the body, and the body comprises a conversion gap accommodating the spacing conversion portion; the spacing conversion portion comprises a plurality of groove bodies of different spacing for accommodating the optical fibers. The fiber holding tool according to the present invention can use the original fusion splicer to weld the ribbon fiber having a diameter of 200 m, without replacing with a new supporting optical communication device, which results in low cost, and can ensure welding quality, and ease the operation.

A pitch conversion device includes a main body portion configured to allow an optical fiber to be arranged thereon; and a turning portion configured to be attached to the main body portion. The turning portion includes a first holding portion configured to hold a plurality of the optical fibers at a first pitch, and a second holding portion configured to hold a plurality of the optical fibers at a second pitch. The turning portion rotates around an axis passing through an inside thereof in a state of being attached to the main body portion. A position at which the optical fibers are held is changeable to the first holding portion or the second holding portion depending on a rotation angle of the turning portion.

The present disclosure relates to an optical splice package for splicing together first and second optical fibers or first and second sets of optical fibers. The optical fibers have elastic bending characteristics. The splice package includes a splice housing including a mechanical alignment feature for co-axially aligning ends of the first and second optical fibers or sets of optical fibers within the splice housing. The splice housing contains adhesive for securing the ends of the first and second optical fibers or sets of optical fibers within the splice housing. The optical package has a weight less than a spring force corresponding to the elastic bending characteristics of the first and second optical fibers or sets of optical fibers.

An optical fiber termination tool includes a tool base having a pocket to receive a mechanical splice optical fiber connector; a lever hingedly connected to the tool base, the lever including a wedge; and a slide mounted to the lever, the slide slidable relative to the lever, the slide movable from a first position to a second position to move the wedge from a disengaged position to an engaged position.

A multi-electrode system includes a fiber holder that holds at least one optical fiber, a plurality of electrodes arranged to generate a heated field to heat the at least one optical fiber, and a vibration mechanism that causes at least one of the electrodes from the plurality of electrodes to vibrate. The electrodes can be disposed in at least a partial vacuum. The system can be used for processing many types of fibers, such processing including, as examples, stripping, splicing, annealing, tapering, and so on. Corresponding fiber processing methods are also provided.
