Claim:
1. An optical fiber connector comprising a frame and a ferrule connectable together, the ferrule being configured to house an optical fiber, wherein: the frame comprises an interior passage, a frame body that houses the interior passage, and a key insert for mating with the ferrule, the key insert being positioned in the interior passage and attached to the frame body, the key insert including an end having an opening surrounded by a rim of the end, the key insert further including a plurality of first mating members configured to mate with the ferrule; the ferrule comprises a ferrule body and a flange protruded from the ferrule body, the flange including a plurality of second mating members configured to mate with the plurality of first mating members; the plurality of second mating members comprises a first pre-determined number of substantially-similar V-grooves formed on a lateral surface of the flange, wherein each of the V-grooves having two sides; and the plurality of first mating members comprises the first pre-determined number of substantially-similar tips protruded from the rim, wherein each of the tips having an outer surface, and wherein for each of the two sides of each of the V-grooves, at least a portion thereof forms a substantially-seamless contact with a part of the outer surface when the plurality of second mating members mates with the plurality of first mating members, preventing the individual tip from making a motion in a direction parallel to the lateral surface of the flange to thereby resist an undesired angular displacement between the connector and the optical fiber to occur due to a rotational force applied to the connector after the frame and the ferrule are connected.
