A passive optical fiber switch includes: a housing defining a plurality of ports configured to receive fiber optic connectors; a substrate positioned within the housing, the substrate defining a plurality of waveguide paths; and an arm positioned relative to one of the plurality of ports such that the arm moves as a fiber optic connector is positioned in the one port, movement of the arm causing the waveguide paths to shift to break a normal through configuration.

A high-capacity optical fiber switching system enables selective interconnection of individual input fibers to output fibers. A three-dimensional array of paired linear elements with selectable flexibility and length is arranged in horizontal rows and vertical columns to form a transverse interchange plane. Each pair consists of a stationary lower element and a movable upper element, the latter holding a terminus of a distinct optical fiber. Couplers placed within this array facilitate signal conductor connections. A transport device with an axially movable gripper moves in horizontal spaces between columns to reposition the movable fiber terminals. Signal-controlled, orthogonal linear drives provide vertical and horizontal movements of the transport device, enabling placement within the fiber array.

An optical switch and system including the same are provided. The optical switch includes (i) a fastening portion configured to releasably attach directly or indirectly to a fuse casing, (ii) a cable connecting portion including a first fiber optic cable connection port, a second fiber optic cable connection port, and an optical through-channel extending from the first fiber optic cable connection port and the second fiber optic connection port; and (iii) an actuator configured to move between a first position associated with a non-blown fuse and a second position associated with a blown fuse. The actuator includes an optical blocking portion that is moved into or within the optical through-channel of the cable connecting portion when the actuator is in the second position.

The invention refers to an optical fiber coupling device for ensuring contamination-free coupling and uncoupling of an optical fiber to a further optical component. The optical fiber coupling device comprises a lid mechanism for opening and closing an axial channel of the optical fiber coupling device. The lid mechanism comprises a driver element and a lid element. The driver element is arranged on an exterior side of a main coupling structure of the device and is movable between a first and a second position. The lid element arranged in an interior of the main coupling structure and is movable between a closed position, in which the lid element closes the axial channel, and an open position, in which the lid element exposes the axial channel. The lid element is magnetically coupled to the driver element. The invention further refers to a laser module comprising the optical fiber coupling device.
