Ferrule assemblies having a lens array

A ferrule assembly comprising:

• a ferrule body comprising:
• a first end face and a second end face;
• an array of holes extending between the first end face and the second end face;
• and
• at least one ferrule body alignment feature at an outer perimeter of the ferrule body;
• a lens array substrate comprising:
• a first end face and a second end face;
• an array of blind holes extending from the second end face, wherein each blind hole of the array of blind holes comprises a tapered opening;
• an array of lenses at the first end face, wherein the array of lenses is aligned with the array of blind holes;
• and
• at least one lens array alignment feature at an outer perimeter of the lens array substrate,
• wherein the second end face of the lens array substrate contacts the first end face of the ferrule body such that the array of blind holes of the lens array substrate is aligned with the array of holes of the ferrule body, and each of the at least one ferrule body alignment feature and the at least one lens array alignment feature is a notch or a positive feature.
