  • Patent number: 11275221
    Abstract: An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly. When the latch pin passes over the apex and resides in a recess, an audible sound is made indicating the hybrid assembly adapter and coupling nut is mated.

  • Patent number: 11275219
    Abstract: A multi-fiber, fiber optic connector is interchangeable between a male connector and a female connector by including a pin retainer having a releasable retention device configured to lock the pins in place within the retainer. The retention device may be opened, for example, with a release tool, to free the retention pins for removal of the pins. A method for switching a connector between a male connector configuration and a female connector configuration may be possible as a result of the releasable retention configuration.

  • Patent number: 11275217
    Abstract: A field installable fiber optic connector is formed without the need to splice two opposing optical fibers together. A ferrule flange assembly with one or more crimp zones secures an optical fiber therein. The assembly is secured within a plug frame housing that has a bias spring, both secured therein by an extender cap. A cable retainer with at least two wings secures the optical cable when a retainer nut is screwed onto a backpost of the extender cap.

  • Publication number: 20220075126
    Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A mating receptacle (transceiver or adapter) includes internal alignment slots configured to accept a corresponding alignment key on connector outer housing to ensure alignment and orientation for maximum signal transfer between opposing ferrule end faces.

  • Patent number: 11256041
    Abstract: A multiple fiber push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and including a stepped portion extending from at least one pair of opposing exterior surfaces of the ferrule. A one-piece housing-backpost is provided having a distal end in a connection direction and a proximal end in a cable direction. The one-piece housing-backpost is configured to receive a ferrule spring and the ferrule from the distal end. The housing-backpost includes at least one resiliently-deformable ferrule-retaining protrusion extending from a sidewall to engage the corresponding stepped portion of the ferrule. The resiliently-deformable ferrule-retaining protrusion is configured to deform towards the housing-backpost interior sidewall as the ferrule is inserted from the distal end and to extend outward against the stepped portion of the ferrule when the ferrule is seated in the housing-backpost to maintain the ferrule in the housing-backpost.

  • Publication number: 20220026643
    Abstract: A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.
