An assembly comprises an optic cable comprising a plurality of optic fiber subunits each comprising at least one optic fiber encased in a fiber jacket and a plurality of aramid strands is disclosed. The assembly further comprises one or more blocks comprising a passage ways for receiving the optic fiber subunits and maintaining adjacent ones of the optic fiber subunits at a predetermined spacing. A housing is moulded over the open end of the cable jacket, the aramid strands and the first end of the at least one block. A method of overmoulding a transition between an optic fiber cable and a furcation jacketing is also disclosed wherein a mould comprises ribs arranged at right angles to an axis of the mould and such that aramid strands are prevented during injecting from reaching a surface of the mould.

A novel panel-mountable fiber optic cable feedthrough is described that has two main body parts that can be brought together around single or multiple fiber optic cables and secured in place to prevent slippage of the cable(s). Use of two such main body parts that split along a plane that passes through the axis of the fiber optic cable(s) allows joining the two main parts at any position along the cable(s) without the need to thread the cable(s) through a one or more pre-formed cylindrical cavities in the body of the feedthrough. The main parts for this fiber optic feedthrough can be made by plastic injection molding suitably shaped to relieve bending strain in the glass optical fiber(s) within the cable(s). The foot-print for mounting such a feedthrough can be made compatible with that of a number of popular fiber optic connector mounts, including the SC-connector.

A fiber optic cable sub-assembly comprises a fiber optic cable including at least one optical fiber, a cable jacket that houses the optical fiber and at least one metal strength member. A collar is attached to an end portion of the metal strength member, wherein the optical fiber extends beyond an outer axial end of the collar. In another example a fiber optic cable assembly is fabricated from the fiber optic cable sub-assembly wherein a connector housing is attached to the collar, and an interface operably connects an end portion of the optical fiber to an active optical component within the connector housing. In further examples, methods of assembly for a fiber optic cable sub-assembly are provided along with using the sub-assembly for making a fiber optic cable assembly.

A ferrule-based fiber optic connectors having a connector assembly with a ferrule having an integral ferrule insertion stop for limiting the insertion of the ferrule into a ferrule sleeve are disclosed. In one embodiment, the fiber optic connector comprising a connector assembly, a connector sleeve assembly and a female coupling housing. The connector assembly comprises a ferrule and a resilient member for biasing the ferrule forward and the connector sleeve assembly comprises a housing and a ferrule sleeve, where the ferrule of the connector assembly is at least partially disposed in the ferrule sleeve when assembled. The ferrule has an integral ferrule insertion stop that limits the depth that the ferrule may be inserted into the ferrule sleeve.

According to embodiments of the present invention, a cable sealing assembly for providing an environmental seal about a cable includes a housing, a flowable cable sealant and a compression feature. The housing includes first and second housing parts. The first housing part defines a cable passage to receive a cable having a lengthwise cable axis. The cable sealant is disposed in the cable passage. The compression feature forms at least a part of the second housing part and is movable in an installation direction between a ready position and an installed position. The compression feature is shaped and configured to force the cable sealant to flow about the cable in a direction transverse to the cable axis to circumferentially surround a portion of the cable when the compression feature is moved from the ready position to the installed position.

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 cable fixation device (10) includes a base (110), an upright (114) projecting from the base and including a fixation projection (116) having a reduced dimensional portion (118) for receiving a cable tie (124). Ribs (126) are provided for engaging the cable jacket or a wrap around the cable. The base (110) and the fixation projections (116) can be made from molded plastic. The fixation projections (116) can be staggered on the cable fixation device (10). The cable fixation device (10) can be mounted with a snap arrangement (38) to an enclosure (12) with one or more additional cable fixation devices (10).

A strain relief for a fiber optic assembly is provided including a base, a forward cable channel, a rear cable channel aligned with the at least one forward cable channel along a longitudinal axis, and an offset post disposed between the at least one forward cable channel and the at least one rear cable channel. Each of the forward cable channel and the rear cable channel includes a first post and a second post extending from the base. The offset post is disposed along the longitudinal axis, such that when an optical cable is installed into the strain relief the optical cable bends around the offset post out of the longitudinal axis.

An apparatus includes a base having walls that define a track. The track has input and output ends and defines a coiled path that spirals inward from the input end, reaches an inflection point where a direction of curvature is reversed, and spirals outward towards the output end. The track is configured to receive and maintain a majority of an optical fiber in an at least substantially planar coiled arrangement. The apparatus also includes a first transition arm positioned at the input end and a second transition arm positioned at the output end. Each transition arm is configured to be mechanically coupled to the base and includes a groove configured to receive and maintain a portion of the optical fiber in an at least substantially straight orientation. The walls and transition arms are configured to maintain thermal contact with the optical fiber along its entire length.
