OPTICAL FIBER CONNECTOR AND METHOD FOR USING SAME Abstract In a plug-type optical fiber connector low loss can be achieved, without any active alignment of the fiber cores, if the two cylindrical plugs used in the connector are "contiguous" plugs, i.e., derived from contiguous segments of the tubular stock from which the plugs are produced and if the plugs are arranged such that the "contiguous" ends of the plugs are the mating ends, and such that the rotational relationship between the plugs is substantially the one that existed prior to sectioning. The inventive connector comprises two contiguous plugs and includes features that permit identification of the contiguous ends and of the rotational relationship. In a preferred embodiment, the tubular stock is drawn glass stock, the two contiguous segments are left joined but scored circumferentially to permit easy separation in the field, with a longitudinal groove in the outer cylinder surface of the contiguous segments identifying the original rotational relationship. The plugs are to be inserted into an alignment sleeve, or into, e.g., three-rod alignment means. Disclosed is also a novel corrugated tube alignment sleeve that has general applicability in plug and sleeve-type connectors.
