Ferrule assemblies, connector assemblies, and optical couplings having coded magnetic arrays

A ferrule assembly comprising:

• a ferrule body having a coupling surface;
• a coded magnetic array including a bulk magnetic material positioned within the coupling surface of the ferrule body and comprising a plurality of magnetic regions;
• and
• a lens component located within the ferrule body, the lens component comprising a facet at the coupling surface of the ferrule body, wherein the coded magnetic array is configured for mating the lens component.

A ferrule assembly comprising:

• a ferrule body having a coupling surface and an angled rear wall located within an optical path of the ferrule body;
• a coded magnetic array located within the coupling surface and comprising a plurality of magnetic regions;
• and
• a lens component located within the optical path of the ferrule body, the lens component comprising a facet at the coupling surface of the ferrule body so that an optical signal propagating within the lens component is reflected by the angled rear wall, wherein the coded magnetic array is configured for mating the lens component.
