Patent number: 8870467Abstract: An apparatus includes a connector that connects to optical fibers for connecting first and second optical signals to the apparatus. A first optical ferrule is mounted perpendicularly to the connector, and transfers the first optical signals between the connector and first optical transducers mounted on a first substrate, via first holes formed in the first substrate. A second optical ferrule is mounted perpendicularly to the connector, and transfers the second optical signals between the connector and second optical transducers mounted on a second substrate, via second holes formed in the second substrate. A light rotation module bends and transfers the first and second optical signals between the connector and the first and second ferrules. One or more lenses are mounted between the first ferrule and the first holes, so as to couple the first optical signals via the first holes between the first ferrule and the first optical transducers.Type: GrantFiled: December 30, 2012Date of Patent: October 28, 2014Assignee: Mellanox Technologies Ltd.Inventors: Shmuel Levy, Shai Rephaeli, Nimer Khazen, Yonatan Malkiman

Patent number: 8864389Abstract: An optical fiber connector includes a connector housing and a positioning unit. The connector housing has two opposite side walls, a base wall disposed between and interconnecting the side walls, and a lid disposed between and inter-engaging releasably the side walls. The connector housing defines an inner space, and an access opening in spatial communication with the inner space and covered by the lid. The positioning unit is mounted in the inner space and includes first and second holding members and a coupling sleeve extending into and interconnecting the first and second holding members. The positioning unit is inserted into the inner space through the access opening so as to be mounted in the inner space before covering the access opening with the lid.Type: GrantFiled: February 4, 2013Date of Patent: October 21, 2014Assignees: Gloriole Electroptic Technology Corp., Ample Sun Trading LimitedInventor: Jim Lin

Patent number: 8858090Abstract: Ferrule holders with an integral lead-in tube employed in fiber optic connector assemblies, and related components, connectors, and methods are disclosed. By integrating the integral lead-in tube as part of the ferrule holder, the integral lead-in tube may be less expensive to manufacture and easier to install. The integral lead-in tube may also be less susceptible to inadvertent removal by friction with a bonding agent syringe or by vibration during shipment. The ferrule holder may include a ferrule holder body and integral lead-in tube. The integral lead-in tube may guide an optical fiber from a rear end of a fiber optic connector to an internal passage of the ferrule holder, where the optical fiber may be further guided to a ferrule for precise alignment. The integral lead-in tube may also protect the optical fiber during installation, shipment, and use in the fiber optic connector.Type: GrantFiled: June 5, 2012Date of Patent: October 14, 2014Assignee: Corning Cable Systems LLCInventors: Charles T.
