  • Optical fiber connector
    Patent number: 10816736
    Abstract: An optical fiber connector includes a main unit and a housing unit. The main unit includes a boot and a connector module that has a rear part connected to a front end of the boot, and a front coupling end distal from the boot. The housing unit includes a sliding sleeve sleeved slidably around the connector module, and a light blocking member pivotally connected to the sliding sleeve. The sliding sleeve is operable between a light blocking position, where the light blocking member blocks light from the front coupling end, and a fiber coupling position, where the light blocking member rotates relative to the sliding sleeve and allows the front coupling end to be exposed from the sliding sleeve.
