A method for manufacturing an intermittently coupled-type optical fiber ribbon includes arranging a plurality of optical fibers in parallel in a direction orthogonal to a longitudinal direction of the plurality of optical fibers, coating all of the plurality of optical fibers with a coupling resin, intermittently inserting a cleaving blade into the coupling resin between some adjacent optical fibers of the plurality of optical fibers to form slits. An outer diameter of each of the optical fibers is 220 μm or less. A distance between the optical fibers into which the cleaving blade is inserted among the adjacent optical fibers is 10 μm or more and 100 μm or less.

The present disclosure describes an optical fiber splice closure for joining two fiber optic cables. The optical fiber splice closure comprises a strain relief assembly that securely holds the two fiber optic cables being connected, and an enclosure that houses the strain relief assembly. The configuration of the strain relief assembly allows for securing the two fiber optic cables in a compact space, thus permitting a compact enclosure of the optical fiber splice closure, while also providing quick and easy installation in the field. A method of joining fiber optic cables using the optical fiber splice closure is also disclosed. The optical fiber splice closure and ease of joining also facilitates repairing damaged fiber optic cable. A method of repairing existing fiber optic cable is disclosed.

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 ribbon is configured by arranging in parallel and coupling a plurality of single-core optical fibers. The optical fibers adjacent to each other are intermittently bonded by coupling parts at predetermined intervals in the longitudinal direction of the optical fiber ribbon. The coupling parts adjacent to each other in the width direction are disposed to be displaced from each other in the longitudinal direction of the optical fiber ribbon. In the optical fiber ribbon, the adjacent optical fibers are intermittently coupled by the coupling parts in the longitudinal direction, and the amounts of resin of the coupling parts are not uniform in the longitudinal direction of the optical fibers. Moreover, the Young's modulus of resin constituting the coupling part is preferably 130 MPa or less, and more preferably 80 MPa or less.

Embodiments of the present invention provide an improved method of determining splice losses of mechanically terminated optical connectors in the field, without the need of terminating both sides of the fiber link. Embodiments of the present invention also provide means for improving the quality of mechanical splices as utilized in pre-polished fiber optic connectors for terminating single-mode and multimode optical fibers in the field.

A splice module includes a main splicing channel and a rework channel. The main splicing channel has an encapsulated section at which one or more initial splices can be stored. The main splicing channel also includes a non-encapsulated section through which trunk cable fibers of the initial splices extend. If re-splicing is needed, the trunk cable fibers can be accessed at the non-encapsulated section, cut, and re-spliced to a new connectorized pigtail or other optical fibers.
