  • Patent number: 6632025
    Abstract: 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.

  • Patent number: 6607308
    Abstract: A fiber-optic module having a housing/shielding unit and a module chassis frame having optical, electrical and electro-optical components. The housing/shielding unit functions both as a protective outer housing and an electromagnetic shield. The housing/shielding unit includes forward fingers and backward fingers. The forward fingers provide an EMI seal around an opening in a bezel, face-plate, backplate, wall, or panel of a host system and thereby can ground the housing/shielding unit to a chassis ground. The backward fingers can contact host tabs of the host system and can also thereby ground the housing/shielding unit to a chassis ground. The module chassis frame may be formed of a conductive material and can be grounded as well through a host system faceplate or otherwise to the chassis ground.

  • Patent number: 6604864
    Abstract: 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.

  • Patent number: 6592269
    Abstract: An apparatus and method integrates optical transceivers for transfer of signals between optical and electronic media with surface mount packages, such as ball grid arrays and quad flat packs. A surface mount package is positioned directly beneath a modular optical transceiver. The surface mount package provides for electrically coupling external signals to the optical transceiver, so as to allow full performance functionality of data transfer components. An electrical coupling mechanism with high performance at high frequency is positioned between the surface mount package and the optical transceiver, electrically connecting them. In one implementation, the optical transceiver module is mounted directly to said surface mount package such that it is removable. In one embodiment, heat dissipation is provided by integral components and thermal vias, in addition to heat sinks.

  • Patent number: 6554484
    Abstract: 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 control circuit responds to the indication by activating or deactivating a laser, for example, which applies optical energy to the adapter. 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.
