Patent number: 6632025Abstract: A high power expanded beam and methods for making and using the high power expanded beam connector are described herein. Basically, the high power expanded beam connector includes a first lensed optical fiber that is optically coupled to a second lensed optical fiber but physically separated from the second lensed optical fiber. The first lensed optical fiber is capable of expanding a light beam traveling therein and outputting a collimated light beam. The second lensed optical fiber is capable of receiving the collimated light beam and focusing the received light beam such that the light beam travels from the first lensed optical fiber to the second lensed optical fiber. In a similar manner, the high power expanded beam connector can transmit a light beam from the second lensed optical fiber to the first lensed optical fiber.Type: GrantFiled: May 16, 2002Date of Patent: October 14, 2003Assignee: Corning IncorporatedInventor: Ljerka Ukrainczyk

Patent number: 6604864Abstract: A retainer (60) at the rear of each passage (14) that holds an optical fiber terminus (30), abuts the rear end (62) of a spring to normally retain the terminus while allowing its removal, with the retainer being rugged, easily manipulated, and of small diameter to allow numerous passages to lie close together. Each retainer has a primarily cylindrical outer surface (74) but with a pair of projections (80, 82). The rear portion of the passage has a first part (90) through which the retainer can be slid forwardly while the retainer is in an initial rotational orientation. A third passage part (94) receives the retainer and allows it to be turned from the initial orientation (60A) to a lock rotational orientation (60B). A second passage part (92) that lies between the first and third passage parts, allows the projections to move rearwardly into recesses (112) that prevent rotation of the retainer and that have forwardly-facing shoulders (114) that abut the retainer to limit its rearward movement.Type: GrantFiled: April 17, 2001Date of Patent: August 12, 2003Assignee: ITT Manufacturing Enterprises, Inc.Inventor: Can Trong Nguyen

Patent number: 6554484Abstract: An optical fiber connector adapter has a sensing mechanism for determining when the adapter has a connector plug therein and when the adapter is vacant or empty. The sensing mechanism creates an indication of the state of the adapter which is transmitted to a control circuit.

The laser is deactivated when the adapter has no connector plug therein and is activated when there is a connector plug in place in the adapter. In two of the embodiments of the invention, the sensing mechanism signals the impending insertion or withdrawal of the connector plug relative to the adapter.Type: GrantFiled: December 27, 2000Date of Patent: April 29, 2003Assignee: Fitel USA Corp.Inventors: Norman R.
