Angled Multifiber Ferrule Geometry for Polarity-Changeable Connectors

The patent applies asymmetry by skewing the angled ferrule contact surface at a specific angle (e.g., 8 degrees) relative to the transverse axis. This creates an asymmetric geometry that provides unique alignment features enabling polarity identification and changeability. The skewed contact surface allows the connector to be inserted in two orientations while maintaining proper fiber alignment, resolving the contradiction between reliability and device complexity by using geometric asymmetry rather than complex mechanical switching mechanisms

The patent applies parameter changes by specifying a precise skew angle parameter (e.g., 8 degrees) for the angled ferrule contact surface. This parameter change transforms the traditional perpendicular or symmetric angled contact surface into a skewed configuration that enables polarity changeability. The defined skew angle parameter allows for standardized manufacturing processes and quality control, resolving the contradiction between adaptability and manufacturing precision by establishing a specific geometric parameter that can be consistently manufactured

The patent applies preliminary anti-action by incorporating asymmetric alignment features (such as positioning protrusions and corresponding recesses) on the connector housing that prevent improper orientation insertion before the ferrule contact surfaces can engage. This preliminary preventive measure ensures that only properly oriented connections are made, eliminating the risk of high insertion loss from misalignment. The asymmetric features create mechanical interference that blocks incorrect orientations, resolving the contradiction between adaptability and energy loss by preventing harmful states before they occur
