Optical receptacles having compliance support interface for facilitating alignment with fiber optic connectors during insertion, and related components, systems, and methods
View Patent ↗Optical receptacles having compliance for facilitating alignment with fiber optic connectors during insertion, and related components, systems and methods are disclosed. In one example, an optical receptacle disposed in a receptacle optical assembly optically connects to a fiber optic component, for example, a ferrule, for facilitating transmission of an optical signal from the optical receptacle to the exemplary ferrule. A support interface between the optical receptacle and receptacle housing contains a compliance feature that permits the optical receptacle to move with respect to the receptacle housing during insertion of the fiber optic connector. An insertion force of the fiber optic connector causes the optical receptacle to be able to move into optical alignment with the connector during insertion of the fiber optic connector, thereby moving ferrule(s) of the fiber optic connector into optical alignment with the ferrule(s) of the optical receptacle.
