Abstract: A waveguide includes a plurality of sets of layers arranged in a stack. Each set of layers includes a first layer that comprises at least tantalum and oxygen, and a second layer that comprises at least silicon and oxygen. The waveguide is configured to propagate light associated with a particular wavelength in a first direction that is orthogonal to a second direction in which the plurality of sets of layers are arranged in the stack. A quantity of the plurality of sets of layers is greater than or equal to 15. Respective thicknesses of the first layer and the second layer, in the second direction, are less than or equal to a fifteenth of the particular wavelength.

Abstract: A concealment component for an optical sensor device includes an optical filter and one or more diffusive optical structures. The one or more diffusive optical structures are configured to distribute light in a diffused pattern on an input surface of the optical filter. The optical filter is configured to pass a first set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are associated with a particular wavelength range, and prevent a second set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are not associated with the particular wavelength range, from passing. Preventing the second set of light beams from passing is to cause the second set of light beams to be directed away from or absorbed by the concealment component in a concealment pattern.

Abstract: A pluggable transceiver receives, from a client, a first message that indicates a first source IP address as being an IP address of a client, a first destination IP address as being an IP address of the pluggable transceiver, a first source port as being a port of the client, and a first destination port as being a port of the pluggable transceiver. The pluggable transceiver updates the first message to indicate the first source IP address as being the IP address of the pluggable transceiver, the first destination IP address as being an IP address of a server, and the first destination port as being a port of the server. The pluggable transceiver sends the updated first message to the server.

Abstract: In some implementations, a device may receive, from a path monitoring subsystem, an indication of a path risk associated with a path to a resource in a computing environment. The device may transmit, to a client device, digital authorization data based on a threat posture associated with an application in the computing environment, wherein the threat posture is based on the path risk associated with the path, and an access request by the client device to access the resource is based on the digital authorization data.

Abstract: Methods and systems for adjacent channel leakage ratio (ACLR) measurement in a cellular network are provided by creating a measurement timing for a symbol or signal transmitted from a base station of the cellular network in an allocated frequency band, measuring power levels of the signal in the allocated frequency band based on the created measurement timing, and measuring power levels in adjacent bands based on the created measurement timing, and deriving the ACLR measurement from the measured power levels in the allocated frequency band and the measured power levels in the adjacent bands.

Abstract: A microscope may receive a fiber optic connector via a connector adapter of the microscope, wherein the connector adapter includes an opening and a shaped reflective surface surrounding the opening. The microscope may align a ferrule of the fiber optic connector with the opening of the connector adapter of the microscope, wherein the ferrule includes a ferrule chamfer or a ferrule radius. The microscope may transmit direct light onto the shaped reflective surface and may receive reflected light from the ferrule chamfer or the ferrule radius and with a camera of the microscope.

Abstract: Apparatuses and methods for implementing a real-time Open Radio Access Network (O-RAN) fronthaul analyzer are provided. In one example, a hardware accelerator may receive and timestamp packets in an O-RAN fronthaul packet traffic flow, parse and route the time-stamped packets on different circuit paths to one or more hardware packet analyzers, where the one or more hardware packet analyzers generate analytical timing measurements in real-time using the timestamps on the plural packets. In some examples, the hardware accelerator may include a flow tracker to track packet flows and a parser to parse metadata from packet headers and route individual packets onto appropriate circuit paths. In some examples, the real-time O-RAN fronthaul analyzer may be used for testing an O-RAN fronthaul link for compliance with O-RAN standards.

Abstract: According to examples, an O-RAN FHA may include a packet analyzer including hardware, an impairment generator, and a Parser to receive packet traffic flows outputted by an O-DU) and/or an O-RU. The Parser may parse packets in the received packet traffic flows, determine which of the received packet traffic flows are to receive impairments, and set action bits for the packets in the packet traffic flows that are to receive impairments, in which the action bits denote information indicating types of impairments to be applied to certain ones of the packet traffic flows. The Parser may also output the packet traffic flows with the action bits set for the packets to the packet analyzer and the impairment generator, in which the impairment generator is to generate impairments on the packet traffic flows based on settings of the action bits for the packets in the packet traffic flows.
