US Patent 11709324 Self-aligning rotating optical connector

An optical connection includes a plurality of ferrules, an optical contact to allow transfer of light, a mechanical contact to allow torque transfer from the optical connection, and a rotational self-alignment structure to allow optical fibers of different optical connectors to self-rotate into rotational self-alignment upon action of connecting, wherein the ferrules are aligned and engage the torque transfer. The rotational self-alignment structure can be a tooth configuration, a helical thread configuration, a ferrule guide configuration, a spring sleeve configuration, derivatives thereof and combinations therefrom.
