  • DUPLEX OPTICAL CONNECTOR WITH LATERALLY REPOSITIONABLE CONNECTORS AND PULL BOOT RELEASE
    Publication number: 20230280543
    Abstract: A duplex optical connector includes a holder, a pair of optical connectors rotatably disposed in the holder, a cable boot slidably attached to the holder, and a clip removably attached to the holder. The clip functions to maintain a lateral position of the optical connectors relative to the holder and transfer applied force on the pull boot into actuating force on the connector latches. Connector openings formed in the holder are elongated in the lateral direction to provide separate use and polarity reversal connector positions, wherein the connectors non-rotatably engage the holder in their use position and rotatably engage the holder in their polarity reversal position.
