  • Patent number: 12072536
    Abstract: A retaining mechanism engages springs in a fiber optic connector to prevent movement of the springs relative to the fiber optic ferrules and the housing during curing of an epoxy inserted into the fiber optic connector. The retaining mechanism may be removably attached to the housing of the fiber optic connector. It may be inserted from a rear end of the fiber optic connector or disposed around an outside portion of the housing. The retaining mechanism may also be integral with an inside surface of the housing.

  • Patent number: 12055770
    Abstract: A tool is used for inserting and removing an MT-type fiber optic ferrule from an adapter. The tool includes a handle having one or both of an insertion portion and a removal portion. An insertion head is movably coupled to the insertion portion of the handle. A removal head is movably coupled to the removal portion of the handle. The handle has opposing ends for the insertion portion and the removal portion. The handle may have other configurations. A sliding lock may be used to lock the rotatable insertion portion and rotatable removal portion in a fixed position relative to the handle.

  • Patent number: 11982847
    Abstract: A push-pull boot for an MPO fiber optic connector has rear portion, a middle portion, a transition portion disposed therebetween, at least two front extensions extending from the middle portion and a cross bar between the at least two front extensions. The push-pull boot has a spine that extends from an end of a rear portion to the transition portion and parallel to a longitudinal axis. The push-pull boot may also have a rear facing surface that is configured to engage a forward facing surface on the outer housing during a pulling operation. It may also have a spring push seat located in the middle portion of the push-pull boot and configured to engage a spring push of the MPO fiber optic connector during a pushing operation of the MPO fiber optic connector.
