Disclosed is a fiber cable terminal which comprises a cable assembly, a cable fixing portion and a thermal shrinkable tube. The cable assembly includes: an inner sheath through 5 which the fiber can pass; and a protection layer provided outside of the inner sheath. The cable fixing portion includes: an insertion portion to be inserted between the protection layer and the inner sheath; and a fixing portion connected with the insertion portion and positioned outside of the protection layer. The thermal shrinkable tube wraps a part of the fixing portion and a part of the protection layer and fixes the cable fixing portion and the 10 cable assembly together. All the members of the fiber cable terminal are pre-assembled into a sealed one-piece, the sealing performance between the cable fixing portion and the protecting layer is thus improved. The fiber cable terminal is mated with the through hole of the supporting body to improve the sealing performance between the fiber cable terminal and the supporting body.

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.

An assembly includes: first and second fiber optic cables, each of the first and second fiber optic cables including an exposed portion of an optical fiber and an overlying jacket, wherein the optical fiber of the first fiber optic cable is fusion spliced to the optical fiber of the second fiber optic cable to form a splice area; a splice protector that surrounds the splice area of the first and second fiber optic cables; a flexible tube that encircles the splice protector, the exposed portions of the first and second fiber optic cables, and end portions of the jackets of the first and second fiber optic cables, wherein the splice protector, the exposed portions of optical fibers of the first and second fiber optic cables reside in a lumen of the flexible tube; first and second adhesive barriers positioned between an inner surface of the flexible tube and the end portions of the first and second fiber optic cables, respectively; and an outer sleeve that circumferentially overlies the flexible tube and portions of the jackets of the first and second fiber optic cables.

This invention discloses a type of optical cable wiring system, including: a main optical cable, first optical cable connector box and optical cable fan-out disposed near a first user zone; a second optical cable connector box disposed at a distance from the first user zone and near a second user zone; and a single main adapter optical cable disposed between the first optical cable connector box and second optical cable connector box. An optical cable fan-out converts a single main adapter optical cable to multiple branch adapter optical cables. Multiple branch adapter optical cables are connected to the main optical cable via a first optical cable connector box; multiple first distribution optical cables for the purpose of connection to a first user zone are connected to a main optical cable via a first optical cable connector box; multiple first distribution optical cables for the purpose of connection to a second user zone are connected to a single main adapter optical cable via a second optical cable connector box. In this manner, it becomes unnecessary to lay multiple second distribution optical cables over long distances between the first user zone and second user zone, thus reducing the laying length of second distribution optical cables, reducing material and labour costs, and additionally improving municipal aesthetics.

Anchoring an input cable (190) at an input port (123, 223) of an enclosure (110) includes inserting the input cable (190) through an anchor member (151, 251) so that a cable jacket (191) terminates within the anchor member (151, 251) and at least one optical fiber (195) extends outwardly from the anchor member (151, 251). The anchor member (151, 251) is secured to the cable jacket (191) using the sheath (175). A cover (162, 260) is mounted to the anchor member (151, 251) to form a pass-through assembly (150, 250) defining an enclosed region. Material is injected into the enclosed region to fix strength members (197) and/or optical fibers (195) of the input cable (190) to the pass-through assembly (150, 250). The ruggedized pass-through assembly (150, 250) is disposed at a base (120, 220) of the enclosure (110).

A fiber optic cable assembly having a reduced cross-dimensional width includes a fiber optic cable carrying a plurality of optical fibers and having a furcation formed at an end thereof. The furcation includes a furcation housing and a plurality of furcation tubes extending from the furcation housing. Each of the plurality of furcation tubes is configured to receive a number of the plurality of optical fibers. The furcation further includes at least one connection interface terminating the optical fibers received in each of the plurality of furcation tubes. At least one of the furcation tubes has a diameter substantially equal to a theoretical minimum diameter corresponding to the number and size of the optical fibers received therein, and may be formed from a heat shrink material. A method of making such a fiber optic cable assembly is also disclosed.

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.

Embodiments of a furcated optical fiber cable are provided. A main distribution cable has optical fibers surrounded by a cable jacket. The optical fibers are divided into at least two furcation legs. A furcation plug is located at a transition point between the main distribution cable and the at least two furcation legs. The furcation plug surrounds at least a portion of the main distribution cable and each of the at least two furcation legs. Optical connectors are provided for each of the at least two furcation legs, and each connector includes optical fibers that are spliced at a splice location to the optical fibers of the connector's respective furcation leg. The splice location is closer to the connector than to the furcation plug. A method of furcating an optical fiber cable and a pulling configuration for the furcated optical fiber cable are also provided.
