Abstract: An optical fiber connector comprises a frame and a ferrule connectable together. The frame has a key insert inside an interior passage of the frame for mating with the ferrule. The ferrule has a flange configured to mate with the key insert. The flange includes a number of V-grooves, and the key insert has the same number of tips for mating with the V-grooves. For each of two sides of an individual V-groove, at least a portion thereof forms a substantially-seamless contact with a part of an outer surface of an individual tip during mating. Hence, the individual tip is prevented from making a motion in a direction parallel to flange, thereby resisting an undesired angular displacement between the connector and an optical fiber therein to occur due to an accidental rotational force applied to the connector after the frame and the ferrule are connected.

Abstract: The present invention provides an optical fiber cable fixing mechanism and method for easy, rapid, and precise installation of an optical fiber in a field-fabricated optical fiber connector without the need for external installation equipment. The optical fiber fixing mechanism comprises a back post, a press ring, and a boot. The back post comprises at least an interior passage allowing the pass-through of the buffered section of the optical fiber cable there within; and at least one clamping latch. When the clamping latch is pressed towards the interior passage of the back post, it clamps on to the optical fiber cable laid there within. The press ring is for hooping around the back post and pressing on the clamping latch. The boot is for securing the press ring around the back post.

Abstract: A mount plate for an optical adaptor includes two bases bridged by a bar and a locking claw stemming out of each of the two bases. Each of the two bases has a folded structure erected at the back end of the base to fill up the gap between the optical adaptor and the hole of the panel and to reduce rattling. Supporting tips are provided at the base of the folded structure to support the folded structure and to keep the base securely attached to the optical adaptor.
