An illuminator including a receptacle for connecting a light cable to an illuminator. The receptacle includes a clamp assembly having a plurality of clamping jaws that are moveable from an open configuration in which a connecter of the light cable can be positioned between the clamping jaws for receiving light traveling in a light pathway in the illuminator to a closed configuration in which the clamping jaws completely block the light pathway, and a clutch that is movable between an engaged position for holding the clamping jaws in the open configuration and a disengaged position for allowing the clamping jaws to move to a gripped configuration and to the closed configuration, the clutch can be pushed by the connector when the connector is positioned between the clamping jaws to move the clutch out of the engaged position so that the clamp assembly moves the clamping jaws to the gripped configuration.

An apparatus including a first ferrule, a second ferrule and a tracing fiber. The first ferrule may comprise a cap. The second ferrule may comprise the cap. The tracing fiber may be configured to propagate light from the first ferrule to the second ferrule. The first ferrule may enable the light to be directed into the tracing fiber when the cap is removed. The cap of the second ferrule may be configured to scatter the light to provide an omnidirectional emission of the light from the second ferrule. The tracing fiber may be bundled with one or more data carrying lines in a cable. Each of the data carrying lines may be configured to enable a communication of data. The tracing fiber may be configured to propagate the light without interrupting the communication of data.

There is provided an interface module (200), comprising: an interface (208) for connection with a signal connector (250); a cage (206) for guiding the signal connector towards the interface; and a heat sink (202). The cage (206) comprises a cage portion (212) that is configured to move from a first position to a second position upon insertion of the signal connector (250) into the cage. In the first position, the cage portion is not in thermal contact with the heat sink; when in the second position, the cage portion is in thermal contact with the heat sink. The cage portion (212) comprises one or more apertures (218).

An optical receptacle of the present invention includes: a first optical surface configured to allow light emitted from the photoelectric conversion element to enter the optical receptacle; a second optical surface configured to emit, toward the optical transmission member, the light having entered through the first optical surface; a positioning part configured to position an end face of the optical transmission member in such a way that the end face faces the second optical surface; and a region disposed at an optical surface in the optical receptacle. The region is configured in such a way that as a distance from an emission position of the light on the second optical surface to a center of the second optical surface increases, a distance from a position where the light intersects a central axis of the second optical surface to the second optical surface increases.

The sliding member is configured to move along the first direction. The rotational member has a hole. The sliding member has a second spindle. The first spindle and the second spindle are fit with the hole. The optical transceiver includes an inner part provided inside the apparatus upon the engagement with the apparatus. The hole has a first circular area, a second circular area, and a straight area. The first spindle is fit with the first circular area. The second spindle is fit with the second circular area. The straight area is connected between the first circular area and the second circular area.

Technologies for allocating resources of managed nodes to workloads to balance multiple resource allocation objectives include an orchestrator server to receive resource allocation objective data indicative of multiple resource allocation objectives to be satisfied. The orchestrator server is additionally to determine an initial assignment of a set of workloads among the managed nodes and receive telemetry data from the managed nodes. The orchestrator server is further to determine, as a function of the telemetry data and the resource allocation objective data, an adjustment to the assignment of the workloads to increase an achievement of at least one of the resource allocation objectives without decreasing an achievement of another of the resource allocation objectives, and apply the adjustments to the assignments of the workloads among the managed nodes as the workloads are performed. Other embodiments are also described and claimed.

A fiber plug facilitates optical coupling of a light-guiding fiber to a plug receptacle and includes a plug housing for receiving and locking parts of the fiber plug in position relative to one another. The plug housing has: a fiber inlet and a fiber bearing for the spatially fixed reception of the fiber; optically downstream of the fiber bearing along a beam path, an optical lens for collecting light exiting at an end face of the light-guiding fiber and for collimating the collected light; and a coupling surface with an output of the beam path and with a coupling structure for connection to a receptacle structure that is complementary to the coupling structure. An adjustable optical element is arranged optically downstream of the fiber bearing in the beam path and has a first component of a magnetic coupling consisting of two components and a first component of a kinematic coupling.
