Ferrule-less Fiber Optic Adapter with V-Groove Alignment

The patent introduces an intermediate fiber alignment device with V-grooves that serves as a mediator between the ferrule-less connector and the fiber ends. The V-grooves provide precise geometric alignment for multiple optical fibers without requiring ferrules, resolving the contradiction by enabling high-precision alignment for numerous fibers simultaneously.

The patent applies local quality by providing individualized alignment features (V-grooves) for each fiber position within the connector. Each fiber receives tailored alignment guidance at its specific location, allowing precise alignment for multiple fibers while maintaining the ferrule-less design.

The patent implements beforehand cushioning by incorporating a protective shroud that covers the fiber ends before connection. The shroud prevents damage and contamination to the fragile fiber ends, ensuring reliable optical connections when multiple fibers are connected in a compact arrangement.

The fiber alignment device with V-grooves acts as an intermediary that ensures proper fiber end alignment and protection, enabling reliable connections for high-density multi-fiber configurations without ferrules.

The patent achieves universality by designing the ferrule-less connector with an adapter interface that is compatible with both conventional SC and LC mounting structures. The connector can be universally installed in existing adapter frameworks while maintaining the advanced ferrule-less multi-fiber alignment technology, thus preserving compatibility with conventional systems.

The connector is segmented into distinct functional zones: the ferrule-less fiber alignment section for high-density fiber connection and the conventional adapter mounting section for compatibility. This segmentation allows each part to optimize its specific function while maintaining overall system compatibility.

The patent merges multiple alignment functions into a single integrated V-groove structure. Instead of requiring separate alignment mechanisms for each fiber, the unified V-groove design simultaneously aligns multiple optical fibers in parallel, reducing device complexity while accommodating increased fiber quantities.

The patent transitions from individual fiber alignment (one-dimensional approach) to multi-fiber parallel alignment (two-dimensional arrangement). The V-grooves are configured to handle multiple fibers simultaneously in a planar arrangement, simplifying the overall alignment structure while increasing connection density.
