  • Publication number: 20200355877
    Abstract: A guide pin for aligning fiber optic ferrules includes an elongated cylindrical element with a proximal end, a distal end, a longitudinal axis therethrough, and a diameter. The distal end has a configuration to be insertable into a first ferrule to align the fiber optic ferrules. The proximal end is configured to be inserted into and retained in a guide pin opening in a second ferrule, the guide pin opening in the second ferrule having a diameter, the proximal end of the elongated cylindrical element having a first portion having a profile that is related to an arc with radius equal to or smaller than the diameter of the guide pin opening and a second portion having a profile defined by a line associated with the arc, the second portion being proximal relative to the first portion.

  • Publication number: 20200348475
    Abstract: An optical connector assembly (OCA) includes a connector housing to maintain alignment between optical components housed within the OCA and photoelectric converters on an optoelectronic substrate (OES) assembly. The optical components include a ferrule and an optical cable. The ferrule is optically coupled to the optical cable. The OCA includes a ferrule holder to hold the ferrule within the OCA, and a spring located between the connector housing and the ferrule holder. The spring is to apply a separating force between the ferrule holder and the connector housing. The OCA includes a gasket coupled to the connector housing. The coupling of the connector housing to a socket compresses the gasket to provide a seal between the connector housing and the socket.

  • Publication number: 20200341210
    Abstract: A fiber optic ferrule and a guide pin clamp allows for changing guide pins in the field. The guide pin clamp has a forward clamp portion, a rearward clamp portion configured to engage the biasing spring and a guide pin retaining plate. The forward clamp portion and the rearward clamp portion move relative to one another to also move guide pin retaining plate from a first position to a second position to allow for the removal or insertion of guide pins.

  • Publication number: 20200341199
    Abstract: A lens plate for fiber-optic ferrules has an inner side and an outer side. The inner side of the lens plate has a plurality of lenses on an inner base in an inner central recessed portion of the inner side, the inner side facing an end face of the fiber-optic ferrule. The plurality of lenses are configured to collimate an optical beam received thereupon. There is an outer base in an outer central recessed portion on the outer side and at least partially circumscribed by an outer face, the inner central recessed portion and the outer central recessed portion at least partially overlie one another. There is also a method for collimating an optical beam output from a fiber-optic ferrule end face using a lens plate.

  • Publication number: 20200341206
    Abstract: A fiber optic connector along with a tool allows for the changing of the polarity of the fiber optic connector. Keys may be installed in both the top and the bottom of the fiber optic connector, one in a first position and the other in a second position. Using the tool in one back-and-forth motion, the polarity of the fiber optic connector can be changed. The keys have a configuration that resist an incorrect insertion and provide better retention of the keys in the correct configuration due to a better retention force.

  • Patent number: 10809482
    Abstract: A device for rearranging optical fibers has a proximal and distal ends. The ends have openings therein to allow optical fibers to pass therethrough. A crimp band may be included at either end to provide strain relief to the optical fibers as they enter and exit from the device. A lid with latches is also provided to assist with organization, security, and compression of the optical fibers. A tool is also provided to disengage the lid from the device.

  • Publication number: 20200301085
    Abstract: An fiber-optic connector assembly includes a fiber optic ferrule and a connector, which engage an optical transceiver component. The fiber optic ferrule engages a mating plane of a lens array in the optical transceiver component and floats within the connector. The engagement of the assembly and the optical transceiver component may be removable rather than fixed. The fiber optic ferrule also engages a mechanical interface to account for three degrees of freedom, while the engagement of the mating surfaces account for another three degrees of freedom.

  • Publication number: 20200301089
    Abstract: A device for rearranging optical fibers has a proximal and distal end. The ends have openings therein to allow optical fibers to pass therethrough. The openings in the distal end have a width that is less than twice the optical fiber's diameter. Dividers separate the distal end openings and have a projection that narrows the distal openings to prevent the optical fibers from accidentally moving out of the openings. A lid is also provided to assist with organization and compression of the optical fibers.

  • Publication number: 20200285001
    Abstract: A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.

  • Publication number: 20200241214
    Abstract: A fiber optic connector assembly is mated with a bracket on a printed circuit board at one end and inserted into a backplane adapter that is adjacent a backplane. In particular a spring push in slidingly attached to the bracket and also to the housing of the fiber optic connector assembly. The housing of the fiber optic connector assembly insertable into the backplane adapter using passive alignment features. A fiber optic ferrule in the fiber optic connector assembly is biased in a forward direction by a spring in the spring push. At the same time the spring allows for movement of the spring push within the housing to allow for movement of the printed circuit board relative to the backplane adapter.

  • Publication number: 20200209490
    Abstract: A fiber optic ferrule has an entrance surface that is angled at an angle that other than perpendicular to the optical fiber axis. The optical fibers disposed within the fiber optic ferrule are preferably separated from the entrance surface. These features reduce the amount of reflection of the light back into the optical fiber and increase the performance of the fiber optic ferrule.
