  • Publication number: 20230288649
    Abstract: In a fiber optic connection system, an adapter has an expandable wall portion that snaps onto a connector and latches with a latch knob of the connector housing. A lock and an extractor are disposed on the connector housing. During insertion, the extractor is in a forward position as the connector housing is inserted into the adapter. The adapter moves the lock backward relative to the housing and extractor, toward an unlocking position, until the adapter snaps onto the latch knob. Then the lock returns to the locking position to lock the connector to the adapter. To extracts the connector, the extractor is pulled backward. This moves the lock backward to unlock the connector from the adapter. Further pulling unlatches the adapter from the latch knob by expanding the expandable wall portion and extracts the connector.

  • Patent number: 11747572
    Abstract: A reversible polarity fiber optic connector includes an outer housing including a polarity key for coupling the outer housing to a fiber optic receptacle in only one orientation. A ferrule assembly is received in the outer housing in a first position corresponding to a first polarity of the fiber optic connector and in a second position corresponding to a second polarity of the fiber optic connector. The ferrule assembly forms an optical connection with the fiber optic receptacle. A boot assembly is releasably connected to the outer housing to enable the ferrule assembly to be inserted into and removed from the outer housing. The boot assembly includes a rotor rotatable between locked and release positions. The rotor includes a blocking portion to block disconnection of the boot assembly with the outer housing in the locked position and to permit disconnection of the boot assembly with the outer housing in the release position.

  • Publication number: 20230135807
    Abstract: An optical fiber connector with a housing configured to hold a plurality of optical fiber ferrules is selectively reconfigurable between a first configuration and a second configuration different from the first configuration. The housing can have different widths in the first and second configurations. The ferrules can have different ferrule arrangements in the first and second configurations. The optical fiber connector can be mateable with different types of receptacles in the first and second configurations. Reconfiguration can be achieved by disconnecting a rear housing from a plurality of front housings at first set of attachment points, rotating the rear housing 180° in relation to the front housings, and attaching the rear housing to the front housings at the second set of attachment points.
