Publication number: 20140016899Abstract: A method of manufacturing an optical cable including plural waveguides each including plural optical channels and each of the waveguides and the optical channels having a first end and a second end. A central portion of each of the waveguides is displaced along a central longitudinal axis of the waveguides which traverses a central bifurcation line of the first and second connectors. A first optical channel connection pattern is formed on the first connector by the first ends of the optical channels of the waveguides connected thereto; and a second optical channel connection pattern formed on the second connector by the second ends of the optical channels of the waveguides connect to the second connector. The first optical channel connection pattern is a different pattern than the second optical channel connection pattern in relation to a connection hole pattern which is the same for both the first and second connectors.Type: ApplicationFiled: September 13, 2013Publication date: January 16, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Russell A.

Publication number: 20130322825Abstract: A multi-fiber fiber optic connector is configured to include a switchable polarity key that can be used to define first and second polarity configurations for the connector. The connector has a multi-fiber ferrule surrounded by an inner housing. The inner housing has top and bottom recesses sized to accommodate the polarity key. The polarity key is removably secured in either a top or bottom recess using a latching feature. The polarity of the connector can be switched by moving the polarity key from one position in the connector to the other rather than having to disassemble the connector.Type: ApplicationFiled: June 4, 2012Publication date: December 5, 2013Inventors: Terry L.

Publication number: 20130308907Abstract: A male optical connector includes a connector body, a hollow pusher, a number of lenses, and two elastic shielding plates. The connector body defines a receiving hole with an opening and includes a connection surface in the receiving hole. The connection surface faces the opening. The pusher extends from the connector body and surrounds the receiving hole. The lenses are received in the receiving hole. The two elastic shielding plates have two fixed ends fixed to opposite sides of the pusher, and opposite free ends overlappable to cover the opening.Type: ApplicationFiled: August 27, 2012Publication date: November 21, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: I-THUN LIN

Publication number: 20130294725Abstract: 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: ApplicationFiled: December 30, 2012Publication date: November 7, 2013Applicant: MELLANOX TECHNOLOGIES LTD.Inventors: Shmuel Levy, Shai Rephaeli, Nimer Khazen, Yonatan Malkiman

Patent number: 8573854Abstract: A fiber optic connector assembly includes a front housing and a rear housing movably coupled to the front housing between retracted and advanced positions. A drive mechanism is coupled to the rear housing that moves the rear housing from the retracted position to the advanced position. Fiber optic connectors are fixedly coupled to the rear housing with a mating end driven with respect to the front housing in a mating direction when the rear housing is moved from the retracted position to the advanced position. Optionally, the fiber optic connector assembly may be side-loaded into position with respect to a fixed connector assembly, and then the fiber optic connector is driven to the advanced position in a direction generally perpendicular to the direction of loading.Type: GrantFiled: April 18, 2011Date of Patent: November 5, 2013Assignee: Tyco Electronics CorporationInventors: Robert C.

Patent number: 8529138Abstract: The invention pertains to a ferrule for aligning optical transports within an optical connector for coupling to a mating optical connector for purposes of aligning the optical transports in the first connector with optical transports in the mating connector. The ferrule comprises a main body portion defining a longitudinal cavity running between a front face and the rear face of the main ferrule body. The cavity has an opening to a lateral side of the ferrule main body that permits the installation of optical transports into the cavity from a lateral direction (as well as still permitting longitudinal installation, if desired). A cover may be provided for closing off the lateral opening after the optical transports are installed in the cavity.Type: GrantFiled: July 15, 2010Date of Patent: September 10, 2013Assignee: Tyco Electronics CorporationInventors: Jeroen Antonius Maria Duis, Jan Willem Rietveld, Marcellus Petrus Josephus Buijs, Ton Antonius Bernardus Gerardus Bolhaar, Joseph Gerardus Maria Vos, Shelly A.
