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 endface. The microscope may transmit light onto the shaped reflective surface and may receive reflected light from the ferrule endface and with a camera of the microscope.

Abstract: A device for cleaning an end face of an optical fiber may receive a first pressure signal from a first pressure sensor, wherein the device includes a pneumatic circuit, wherein the pneumatic circuit includes: one or more circuit components, the first pressure sensor, and a second pressure sensor. The device may receive a second pressure signal from the second pressure sensor. The device may determine, based on the first pressure signal and the second pressure signal, whether a pressure difference across a circuit component, of the one or more circuit components, satisfies a threshold. The device may perform, based on the pressure difference across the circuit component not satisfying the threshold, one or more actions.

Abstract: A microscope may receive a fiber optic connector via a connector adapter that includes an opening and may align a ferrule of the fiber optic connector with the opening of the connector adapter, where the ferrule includes a ferrule endface. The microscope may transmit light onto the ferrule endface and may receive reflected light, as an image of the ferrule endface, with a camera of the microscope. The microscope may determine intensities of brightness of the image and may create a topographical map of the intensities of the brightness of the image. The microscope may determine a radius and an apex of the ferrule endface based on the topographical map and may calculate an apex offset of the ferrule endface based on the radius and the apex of the ferrule endface. The microscope may perform one or more actions based on the apex offset of the ferrule endface.

Abstract: An optical system may include an objective lens system having a primary optical axis and a relay lens system having a relay optical axis. The relay optical axis may have a first angular offset with respect to the primary optical axis. The objective lens system may be configured to provide light from a light source to the relay lens system and provide light from the relay lens system to an image sensor. The relay lens system may be configured to provide light from the objective lens system to an end face of an optical fiber, where the end face has a second angular offset with respect to a cross-sectional axis of the optical fiber. The relay lens system may provide light reflected from the end face to the objective lens system.

Abstract: An optical fiber inspection system may include an alignment guide having a sleeve portion and a mechanical key structure. The sleeve portion may comprise a first opening arranged to be proximal to one or more optical components in an inspection device and a second opening arranged to be distal to the one or more optical components when the alignment guide is removably engaged with the inspection device. The mechanical key structure may be located adjacent to the second opening and have a shape to engage a geometry of one or more recesses in a bulkhead. Accordingly, the alignment guide may stabilize the inspection device at a particular angle relative to an end face of an object in a field of view of the one or more optical components when a shaft of the inspection device is inserted into the bulkhead.

Abstract: A device for connecting to an optical cable having a set of optical fibers may include a microscope, an assembly to move the microscope in a continuous manner about an axis substantially parallel to a mating surface of the optical cable, and without moving the device, to bring one or more optical fibers, of the set of optical fibers, within a field of view of the microscope without moving the optical cable, and one or more processors. The device may receive an indication to perform a set of analyses of the set of optical fibers of the optical cable. The device may perform the set of analyses of the set of optical fibers by modifying a position of the microscope of the assembly of the device in a set of directions. The device may output a result of the set of analyses for display.

Abstract: In some implementations, an optical component of a microscope may capture an image of a profile of a ferrule and a connector of an optical fiber based on the ferrule being received by a first opening of a first connector adapter of the microscope. A mechanical axis of the ferrule may be orthogonal to an optical path from a camera of the microscope to the ferrule when the ferrule is received by the first opening. One or more processors associated with the microscope may process the image to determine a measurement of a chamfer of the ferrule. The optical component may capture an image of an endface of the ferrule based on the ferrule being received by a second opening of a second connector adapter. The mechanical axis of the ferrule may be axially aligned with the optical path when the ferrule is received by the second opening.

Abstract: A device for cleaning an end face of an optical fiber may apply a vacuum to a solvent tank, where the device includes a vacuum generator to apply the vacuum and the solvent tank. The device may receive, from a solvent reservoir and in response to applying the vacuum, solvent with the solvent tank. Additionally, or alternatively, a device for cleaning an end face of an optical fiber may apply a pressure to a solvent reservoir, where the device includes a pressure port to apply the pressure and a solvent tank. The device may receive, from the solvent reservoir and in response to applying the pressure, solvent with the solvent tank.
