Aspects of the present disclosure are related unmanned aerial vehicles tethered to ground stations with an expendable airborne fiber-optic link. The tethers may be fiber-optic cables that can be used as a communications conduit between a ground station and a UAV for providing vehicle positioning/control information to the UAV as well as transmitting a large amount of information/data to the UAV. As the information being transmitted between to the UAV the ground station is critical, fiber-optic cables provide the bandwidth and transmission capabilities required with the added benefit of electromagnetic interference (EMI) and radio-frequency interference (RFI) immunity, making this an ideal solution for these applications.

A fiber optic distribution terminal includes a cable spool rotatably disposed within an enclosure; an optical power splitter and a termination region carried by the cable spool; an optical cable deployable from the enclosure by rotating the cable spool by pulling on a connectorized end of the optical cable; and splitter pigtails extending between the optical power splitter and the termination region. One fiber of the optical cable extending between the connectorized end and the splitter input. The other fibers of the optical cable extend to a multi-fiber adapter.

The present disclosure relates to a fiber management device or system for facilitating routing and storing optical fibers. The fiber management device includes a flexible, film-like substrate that has optical fiber management, storing functionality, and splicing functionality all on one film-like substrate. The flexible, film-like substrate can provide a routing path for routing optical fibers onto a flexible planar substrate that can be temporarily supported by, mounted on or attached to the flexible planar substrate. The flexible, film-like substrate can accommodate fibers that are in a multi-fiber (e.g., ribbon) configuration or a single fiber configuration.

An enclosure box assembly for fiber optic cable includes an enclosure box, a backplate, a preterminated fiber optic drop cable preinstalled with the enclosure box, and a fiber optic adapter preinstalled with the enclosure box and optically connected with the fiber optic drop cable. The backplate includes a plurality of latches that are configured to interlock with a complementary latching structure on the enclosure box, and a plurality of slotted countersunk screw holes configured to receive screws for attaching the backplate to a support structure. The backplate includes a first exit opening through a middle portion of the backplate, a second exit opening at a top end of the backplate, and a third exit opening at a bottom end of the backplate.

Apparatuses and methods for optical fiber loop relaxation are provided for telecommunications management apparatuses, such as fiber optic telecommunications trays. The apparatus includes a radius limiter block for routing fibers therearound, and a fiber loop management recess provided on a peripheral surface of the radius limiter block. The fiber loop management recess is configured to receive a fiber loop management device between the radius limiter block and the fibers routed around the radius limiter block.

Provided is an optical-fiber-cable winding bobbin 100 including: a body member 110 on which an optical fiber cable is wound; and a pair of flange members 120 that are provided at both ends of the body member 110, wherein the flange members 120 are made of ABS resin, and the body member 110 is made of a material having a smaller linear expansion coefficient than the flange members 120.

A telecommunications assembly includes a chassis and a plurality of fiber optic splitter modules mounted within the chassis. Each splitter module includes at least one fiber optic connector. Within an interior of the chassis are positioned at least one fiber optic adapter. Inserting the splitter module through a front opening of the chassis at a mounting location positions the connector of the splitter module for insertion into and mating with the adapter of the chassis. The adapters mounted within the interior of the chassis are integrally formed as part of a removable adapter assembly. A method of mounting a fiber optic splitter module within a telecommunications chassis is also disclosed.

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, fibers can be stored and deployed form storage spools.

An example cable enclosure is provided that includes a chassis, a front cover coupled to the chassis, and first and second slide rails slidably coupled relative to the chassis. The cable enclosure includes a first release lever mounted to the chassis. The first release lever is capable of being positioned into a first position and a second position. In the first position, the first release lever engages the chassis to prevent sliding of the chassis and the front cover relative to the first and second slide rails. In the second position, the first release lever disengages the chassis to allow for sliding of the chassis and the front cover relative to the first and second slide rails.

A system that may be used for deploying optical cables, the system may include a track having an outer edge and a surface, the track having a track gear disposed proximate the outer edge and a plurality of track grooves disposed on the surface of the track. The system may also include a spool having a first outer edge and a second outer edge. The spool may include a first wheel disposed on the first outer edge, a second wheel disposed on the second outer edge, a spool gear disposed on the first wheel and interfacing with the track gear, plurality of spool grooves, and a plurality of guides interfacing with the track to align the track grooves with the spool grooves.
