In order to suppress landing construction, these landing cables, which are installed offshore from a cable landing position, are each provided with: an initially used optical fiber that is used from the initial start of communication by the landing cable; and a preliminary optical fiber which is a preliminary optical fiber in addition to the initially used power feed line used from the initial start, wherein the preliminary optical fiber is connected from a cable landing position side terminal point to boundary points between the cable landing position side terminal point and a cable interval that does not include the preliminary optical fiber, and the terminal point of the preliminary optical fiber, which is the terminal point of the preliminary optical fiber in the boundary points, is held in a state of being usable in the future.

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.

Devices such as multiports comprising connection ports with associated sliding actuators that engage securing members and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, and at least one sliding actuator that engages with a complimentary securing member. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing member is associated with the connection port passageway and translating the sliding actuator allows the release of an optical connector disposed in the connection port.

A configurator design tool is provided to facilitate the manufacture of pre-configured multi-fiber optical cable and loaded optical fiber cable storage reels. The configurator design tool also facilitates the configuration of fiber-optic data centers or other types of fiber-optic infrastructure. The present disclosure also contemplates methodology for manufacturing pre-configured multi-fiber optical cable and loaded optical fiber cable storage reels, and for configuring fiber-optic data centers or other types of fiber-optic infrastructure. Additional embodiments relate to contemplated pre-configured multi-fiber optical cable loaded optical fiber cable storage reels, and to fiber-optic data centers or other types of fiber-optic infrastructures.

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.

A multi-member cable includes at least a first cable element and a second cable element. The first and second cable elements may extend in parallel, be stranded in a helical winding pattern, or be stranded in a reverse-oscillatory winding pattern, along the length of the cable. At least one binder is helically wrapped about the first and second cable elements to hold them together. The binder is formed of a material which disintegrates when exposed to a particular liquid or heat. In a preferred embodiment, the binder may be formed of polyvinyl-alcohol (PVA).

A transition adapter for routing a first optical cable into a plurality of optical cables of the present disclosure has a main body. In addition, the transition adapter has a first channel within the main body and configured for receiving the first optical cable, a second channel, the first channel open to the second channel, the second channel within the main body and configured for receiving a second optical cable, which is a first portion of the first optical cable, the second channel terminating with a first opening from which the second optical cable extends, and a third channel, the first channel open to the third channel, the third channel within the main body and configured for receiving a third optical cable, which is a second portion of the first optical cable, the third channel terminating with a second opening from which the third optical cable extends.

A fixture is for forming a fiber optic array that defines a plurality of discrete fibers extending from a spaced-apart arrangement to a consolidated arrangement wherein the fibers are layered next to each other for a further ribbonizing process.
