Patent number: 11892688Abstract: 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.Type: GrantFiled: February 16, 2023Date of Patent: February 6, 2024Assignee: Senko Advanced Components, Inc.Inventors: Jimmy Jun Fu Chang, Kazuyoshi Takano
