A cable assembly for optical monitoring is assembled by laying optical fibers into an adhesive layer on a substrate to form an optical circuit. First ends of the fibers are arranged in various groups and second ends of the fibers are arranged in various groups. Groups at a first end of the circuit are spliced to coupler input fibers and coupler output fibers. Groups at the second end of the circuit are terminated at one or more input connectors, one or more output connectors, and one or more monitoring connectors. Some cable assemblies monitor signals received at the input connectors. Other cable assemblies monitor signals received at both the input connectors and the output connectors.

Disclosed herein are preconnectorized cable assemblies and methods of making by cable segmentation. One method includes making cable assemblies by adding jacket segments around a cable bundle including a plurality of cable units having at least one optical fiber, and then attaching the plurality of jacket segments together. Another method includes making cable assemblies by inserting jacket segments between base jacket portions. The method includes circumferentially cutting a ring cut in a base jacket surrounding a cable bundle having a plurality of subunit cables with at least one optical fiber. An insert jacket segment is then positioned around the cable bundle and inserted within an access window in the base jacket. The insert jacket segment is joined along a longitudinal slit and ends of the insert jacket segment are attached to the base jacket. A subunit cable of the cable bundle extends through the first side opening.

Disclosed herein are preconnectorized cable assemblies and methods of making using a pull string. One embodiment of the disclosure relates to a method of manufacturing a distribution cable assembly using a pull string fed through a jacket of a distribution cable. Subunit cables are attached to the pull string through openings in the jacket of the distribution cable, and then pulled, via the pull string, through the jacket until drawn through a distribution end opening of the jacket. Another embodiment relates to a distribution cable assembly including junction shells covering side openings in the jacket. The junction shell includes a first half shell attached to a second half shell by a fastener. The first half shell includes stops proximate ends of a side opening to fix the junction shell along an axis of the jacket.

The present disclosure relates to a distribution cable assembly that has various features to enable flexible configurations to accommodate various data center configurations.

A method of laying an optical cable according to the present disclosure includes: installing a laying strip, in which the optical cable is to be embedded, on a road surface or a wall surface; forming a cut line, for embedding the optical cable, on the installed laying strip; and embedding the optical cable in the formed cut line.

Embodiments of the disclosure relate to a method of preparing a bundled cable. In the method, a plurality of subunits is wound around a central member in one or more layers of subunits to form the bundled cable. For a section of the central member, each layer of subunits has a pitch over which a subunit of the layer of subunits makes one revolution around the section of the central member and a length of the subunit required to make the one revolution. The subunits are configured to have a nominal helical length equal to the ratio of a nominal length to a nominal pitch. Further, in the method, a measurement of the bundled cable is monitored, and a winding rate of the plurality of subunits is adjusted based on the measurement in order to account for deviations from the nominal helical length.

A breakout device for mid-span fiber separation. First and second portions that each have a hollow interior space that defines a first part of a primary interior pathway and that defines a first part of a secondary interior pathway that branches away from the primary pathway. The first and second portions together bound the primary and secondary pathways. The first and second portions together define: a first entrance orifice, a second exit orifice and a third exit orifice. The first and second portions are configured to permit in-situ placement of the device upon elongated fibers. All the fibers extend through the first entrance orifice at the entrance to the primary pathway, a first group of the fibers extend through the second exit orifice at an exit from the primary pathway, and a second group of the fibers extend through the third exit orifice at an exit from the secondary pathway.

The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, spare ports can be providing in a forward direction and reverse direction ports can also be provided.

The present disclosure relates to fiber optic components and structures for use in building fiber optic networks using an indexing architecture. In certain examples, fan-out structures are used.
