  • Patent number: 11115735
    Abstract: Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.

  • Patent number: 11099336
    Abstract: An optical fiber connector includes a connector housing module, a fastener, a linkage member, and a pull handle. The connector housing module includes at least one clip arm, and the connector housing module is adapted to be inserted into a target object and buckled to the target object by the clip arm. The fastener buckles the connector housing module. The linkage member is pivotally connected to the fastener and movably abuts against the clip arm. The pull handle movably passes between the fastener and the linkage member to be connected to the linkage member. When the connector housing module is inserted into the target object, the pull handle is adapted to be forced to drive the linkage member to pivot relative to the fastener and press against the clip arm, so as to remove a buckling state between the clip arm and the target object and pull the connector housing module out of the target object.
