Abstract: Systems, methods, and other embodiments associated with computer deepfake detection are described. In one embodiment, a method includes converting audio-visual content of a person delivering a speech into a set of time series signals. Residual time series signals of residuals that indicate an extent to which the time series signals differ from machine learning estimates of authentic delivery of the speech by the person are generated. Residual values from one synchronous observation of the residual time series signals are placed into an array of residual values for a point in time. A sequential analysis of the residual values of the array is performed to detect an anomaly in the residual values for the point in time. In response to detection of the anomaly, an alert that deepfake content is detected in the audio-visual content is generated.

Abstract: Molded fiber optic cable furcation assemblies, and related fiber optic components, assemblies, and methods are disclosed. In one embodiment, an end portion of a fiber optic cable with a portion of a cable jacket removed to expose optical fibers and/or a cable strength member(s) therein and thereafter placing the cable into a mold for creating a molded furcation plug about the end portion of the fiber optic cable. The furcation plug may be overmolded about the end portion of the fiber optic cable. The molded furcation plug can be used to pull a fiber optic cable without damaging the optical fiber(s) disposed within the fiber optic cable. The molded furcation plug is advantageous since it manufactured with fewer parts, without epoxy, and/or without a labor intensive process that may be difficult to automate.

Abstract: A fiber optic connector that employs an optical fiber guide member, and a cable assembly that uses the connector are disclosed. The connector has a connector housing formed by mateable sections. The connector housing defines a housing passage having opposite connector-end and channel-end portions that define respective connector-end and channel-end passages, with the channel-end portion configured to be arranged adjacent the end of a fiber optic cable. An optical fiber guide member is disposed in the channel-end passage and has a first transition end that faces the connector-end passage. The optical fiber guide member has a conduit configured to loosely confine and guide the optical fibers to the connector-end passage. Connector sub-assemblies can be operably supported at the connector-end portion supporting end portions of the optical fiber.

Abstract: Embodiments disclosed herein include ferrule assembly having a ferrule and a ferrule boot that is coupled to the ferrule. The ferrule boot is used for aligning an array of optical fibers in the desired arrangement when entering the ferrule. In one embodiment, the ferrule boot may have a two-piece construction that includes a fiber alignment portion that defines a first groove for a first row of optical fibers and a cover portion. Moreover, the ferrule boot may be configured to accommodate multiple rows of optical fibers. Other embodiments may use a bendable material for the ferrule boot and/or include color coding for aiding the craft with fiber positioning.

Abstract: Fiber optic cable furcation methods and assemblies are disclosed, wherein the method includes removing an end portion of the cable outer jacket from the fiber optic cable to expose end portions of the micromodules contained within. The method also includes helically stranding the exposed micromodule end portions to form a stranded section having a stranded configuration that includes at least three turns and that substantially immobilizes the optical fibers within their respective micromodules. The method also includes arranging a maintaining member on at least a portion of the stranded section to maintain the stranded configuration.

Abstract: A fiber optic connector assembly and method employing one or more fiber movement supports. The one or more fiber movement supports are each disposed around one or more optical fibers and are configured to inhibit kinks or sharp bends from occurring in the one or more optical fibers. The fiber movement support is more rigid than an optical fiber. Thus, when a force is exerted on an optical fiber in a direction angled to the axis of the optical fiber, the force is directed to the fiber movement support. The fiber movement support translates the non-axial force in a direction toward the axis of the optical fiber. This causes the optical fiber to be pushed back towards the fiber optic cable instead of the kinking or bending the optical fiber, thus avoiding or reducing high insertion losses resulting from bending of the optical fiber.

Abstract: An exemplary apparatus includes ferrule offset assemblies each having opposing ferrules with respective ends and respective fiber channels maintained in general relative and adjustable alignment. Offset adjusting devices adjust the relative alignment of the fiber channels to create at least one select fiber channel alignment offset. Respective multimode fibers are disposed in the fiber channels and have a fiber alignment corresponding to the fiber channel alignment. One of the multimode fibers has an end configured to optically couple to a launch multimode fiber, which is connected to a device having a light source. The multimode fiber receives light from the launch multimode fiber so that at least some of the light passes through to the other multimode fiber and then to a power meter. Power measurements for different fiber offsets are then compared to established attenuation values.

Abstract: Disclosed are fiber optic cable assemblies having a composite covering disposed about a portion of a transition location for providing a fiber optic assembly suitable for indoor or indoor/outdoor applications. The composite covering provides a combination of an underlying heat dissipative structure, such as a metal foil along with a high temperature capable substrate, such as mica, thereby providing the desired characteristics for indoor or indoor/outdoor use that a single layer of either material is incapable of providing. The covering may also include an optional flame-retardant wrap as an outer portion for sealing and/or mechanical protection.
