An optical fiber connector in which a terminus assembly (20) can be keyed so it is always installed in a predetermined rotational position about the axis of a terminus-receiving passage (18) of a housing (12). When a terminus rotational position is found that results in minimal insertion loss, a noncircular index sleeve (40) is placed around the terminus body (24) and fixed thereto. An indexing plate (70) is installed in the connector housing, with indexing passage portions (72) that receive the index sleeve at only a single rotational position of the indexing sleeve about the passage axis.
