Abstract: A polarized connector comprises a connector body having an opening for receiving a polarization key. The key comprises a polarization member and slotted shaft rotatable in the opening about a longitudinal axis. The slotted shaft permits user access to the key to rotate the key within the opening in the connector. The polarized connectors described herein permits simple polarization changes with a single key element that is retained with the connector for all polarization configurations.

Abstract: A dust cover for covering one or more fiber optic ferrules of an optical fiber connector. The dust cover comprises a base portion and at least one protruding portion extending therefrom, each of the at least one protruding portion having a cavity therein for receiving one of the one or more ferrules to cover the one or more ferrules when the dust cover is mounted to the connector. The dust cover is particularly designed for connectors having a plurality of ferrules for terminating a plurality of optical fibers, and is especially advantageous for connectors having a retractable body portion which normally surrounds the ferrules when the connector is not in use; and permits all of the plurality of ferrules of a connector to be individually covered substantially simultaneously in a single operation.

Abstract: An optical fiber connector (1) comprises, an alignment ferrule (11) for aligning an optical fiber (3) of an optical cable (2) and a molded, flexible, curved rubber boot (9) extending along a line having a radius of curvature to extend the line 90 degrees from the plane of connection between the ferrule (11) and the boot (9).
